back to article Tesla launches electric truck it guarantees won't break for a million miles

Elon Musk has launched the “Tesla Semi”, complete with a guarantee that it will not break down for one million miles of driving. Speaking at a launch event in Los Angeles, Musk said the truck will be 20 per cent cheaper to operate than a diesel truck, in part because it will be faster. “We designed the truck to be like a …

    Tesla semi?

    Fnar, fnar. But it is a cool looking truck.

    Joking aside I've been talking to a few owners of electric cars (I was thinking about taking the plunge) and I'm hearing worrying tales of range under realistic driving conditions. It seems that the claimed 200-300 mile ranges for "pure" electric models (not just Tesla) can dwindle rapidly if you're not "feather-footing" it, leaving you with 2 or 3 recharging sessions on longer trips.

    Can any commentards here add to this?

      Given that electric motors do operate more efficiently at constant speed, this isn't unreasonable. Quick acceleration, speed changes, etc. will suck up amps just like it would on a gas powered vehicle. So yes, for best efficiency and mileage, a light foot, constant speed (if possible) is required.

        Re: Tesla semi?

        I would include a 4 cyl diesel engine anyway, to charge batteries while driving [or while sitting at a truck stop].

        Just worth pointing out, the worst problem to solve in trucking is ADEQUATE AIR CONDITIONING.

        As a truck driver, you're sitting on top of a high horsepower engine, constantly. Even good insulation isn't enough to block that heat on a hot day. You're gonna ROAST without proper air conditioning. And air conditioning uses power. It gets worse on hills during the summer, like the 'Grapevine' north of L.A., where drivers basically have to go slow in the 'special truck lane' and suffer through the heat. And so on. And the downlhill speed is limited to 15mph as I recall... (for safety). And uphill speed might be slower, depending. So not a lot of wind to help, yeah.

        I suppose if you plan your trip properly, you use energy giong up hill, and try to restore it going down with dynamic braking. But what if the batteries are already fully charged? You'll need a way to dissipate the extra power, maybe a resistor bank with a cooling system [like trains have].

        I have a strong, sneaky suspicion that this electric truck was designed by people who've never driven one on a long haul. So maybe my uncle (who owns a trucking business, though he's close to retiring now) could consult for them. Or any OTHER experienced driver that understands electricity and mechanical engineering, for that matter.

        I think they'll need that. Otherwise, it's like the proverbial "Superiority" (by Arthur C. Clarke) problem.

        New, Shiny not always "superior", yeah.

          Air con only takes a few hundred Watts. The power usage will be lost in the noise. As electric motors are far more efficient that diesel there won't be the heat source in the first place.

          The truck stops will have the mega-chargers so no engine required. I expect initial sales will be point to point though. General purpose will come later when the charging network has expanded out.

          Finally, it'll still have normal brakes. They just won't, normally, be used much.

            I guess you don't drive a truck. The friction brakes will still get used. Every time you leave a proper gap between the truck and the car in front, somebody moves into the space and hits their brakes causing you to hit the brakes too. I pity the armatures in the motors and still think that it won't be enough.

          It won’t have a high horsepower engine so your comment about air con seems misplaced. It will have air con, just like the Tesla cars do. There’s no need for resistor banks as it will have a standard air brake system, just like a normal truck.

            I'll say that having driven a truck both long haul and locally that the design is not going to be enjoyed by many drivers. I don't doubt the engineering is at least reasonable but there is a reason that cabover/forward control horses aren't very popular in the US even though they provide great visibility and it has everything to do with the relative locations of the front wheels and the driver's seat. While this truck appears to have the seat at least a bit behind the front wheels it isn't likely to be anywhere near a nice ride unless you happen to be a big fan of jerk and jounce. Hopefully the weight of the thing will keep it tolerable.

              If this really takes off I can see solar roof panels being retrofitted to trailers, or panel modules that can be attached on top of a shipping container in case the trailer is towed by an electric truck. And if shipping companies have a mixed fleet of solar and non-solar trailers, they can load the solar one if it's Jones The Electric Trucker who's coming to take the trailer to its destination.

              Tesco does deliveries to supermarkets with its own trucks. OK, might be some leasing and other ownership elements, but they're in Tesco markings, They could run a fleet with solar-boost on the trailers. I don't know what they use in urban areas, these could be too big to be practical, and you might not get enough sunlight in England, but there are relatively short-range urban delivery runs.

              And that sort of haulage operation could even swap from a long-range diesel to a Tesla for the urban leg. That does point to something Tesla may have missed. Low-speed urban maybe doesn't care so much about streamlining, but how well will this handle a standard trailer?

      I drive a plug-in hybrid with a claimed electric only range of 30 miles. On a sunny summer's day on pan-flat terrain, given a light foot and driven at a constant 56 mph, that could well be achievable. But I live in the Chiltern hills, with lots of 15% inclines, and I've never seen better than 24 miles. In winter, when batteries are less efficient and there's extra demand for lighting, heating, wipers etc, I often see less than 20 miles. Manufacturers' range figures should be treated like mpg claims for internal combustion vehicles: a good standard comparator, but not likely to be achieved in real-world use.

      As an aside, my car gets around 3 miles/kWh. Tesla claims for its Semi "< 2 kWh/mile" and a range of 300 miles (or 500 with a bigger battery option). So there must be at least 600 kWh of battery, and recharging that to 80% full in 30 minutes is going to need a 1MW supply. Connecting that safely and dealing with the waste heat is a non-trivial engineering challenge in itself. Dealing with 10 or 20 electric trucks simultaneously ...

        Of course, recharging it over the 12+ hours of mandatory rest (with only one seat you can't have two drivers working shifts) would only take ~50kW, and a 50kW diesel genset could be tucked in the back of the trailer along with a 100 gallon tank without sacrificing too much cargo space. Diesel-electric: no range problems, and much more efficient than a straight diesel.

              I agree, it has been used on railways for many decades. But not for efficiency reasons, simply because making a proper mechanical transmission that is economic to build, compact enough to be practical, and reliable for ultra-high torque drive on vehicles in the 35-700 tonne category is not at all easy, verging into the utterly impossible. Whereas diesel electric is, in relative terms.

              There were many attempts to make mechanical drive 100-tonne locomotives, but the system always ended up being less efficient because they needed transmissions involving hydraulic converters that were a big bit crap in many respects.

            There is no reliability problem with diesel engines. Most of the components on semi truck engines have a B50 rating of 750k miles or more. (B50 is a statistic on when 50% of the components would require a major repair, similar to MTBF on computer equipment) And diesels aren't that complex, until you start incorporating computer systems.

            And you wouldn't drop a genset on an electric truck. That would be ridiculous. What you would create is a serial hybrid. It would have just enough battery to boost the available power for accelerating and steep grades. The diesel engine would produce enough power to drive the electric motors at highway cruise speeds. So the weight you gain with the diesel engine, generator, and fuel, you lose by leaving some of those heavy batteries behind. Diesel hybrids need to use some of the decades of experience of the train industry.

            As far as safety is concerned, you'd have the worst of both worlds. BEVs are actually more dangerous that diesel fuel. Between battery charging, dangers from damaged batteries, and hazards to emergency service crews. Diesel, OTOH, is a known component and difficult (compared to gasoline) to ignite.

            Some issues I see with the Tesla truck are that there appears to be no sleeper. So no team drive and the driver has to end their shift at some kind of facility. 60 mph cruise speed is too slow for the United States. 65 or 70 will be required, or you'll lose all your drivers. (drivers get paid by the mile) And it's going to need more than a 500 mile range. 10hrs x 70mph puts you at 700 miles minimum. I'm also curious how they are going to handle the un-sprung weight of having a motor at each wheel.

Refrigerated trailers already have a separate diesel tank and a diesel-powered refrigeration unit that are very noisy. But they add a lot to the cost of the trailer and put 2000Lb of weight high on the headboard, which affects stability.

            The bigger problem I see is that typical over-the-road haulage requires two drivers who drive in shifts so that the truck can run for thousands of miles with only ten minute breaks to switch driver and refuel (fifteen minutes in the USA for pre- and post-trip inspections). An electric truck that has to stop every eight hours (or less) and stand for hours to recharge simply won't compete.

But I guess trucking is an application where careful planning could combine charging with mandatory rest breaks. If it can't, then the economics will be tricky, especially with just-in-time deliveries and contract penalties. ISTR a number of freight customers insist on specific and narrow time windows for deliveries, or penalties are applied.

          And the range if you're making maximum use of the performance, well, halve it? The same is true for ICE vehicles, but if you've got a maximum potential range of 600 miles in your tank, then even if you're driving like you stole it, there's a lot more leeway to refuel than if your maximum battery range is 300 miles, and you're driving in the same manner.

So, for solo routes, the Tesla truck could make sense if it can charge 100% in ten hours. But for long haul OTR, when the trucks run 2000+ miles day and night from say California to Pennsylvania, with two drivers working in shifts, the Tesla truck is a non-starter.

If the battery packs were designed sensibly they'd be interchangeable between cars and trucks. Where a car would require one or two while a truck might require 10 or 20(?).

        Exactly. What's the electric company going to charge to bring in 20MW of capability to an ET truck stop? That's about 167,000 square meters of solar panels (600W/sqm @ 20% efficiency) to be "green".

        If you're looking at claimed range of 30 miles NEDC, it makes sense you've never seen it, because the NEDC is a joke. Unfortunately the "fix" is to use the WLTP, which seems to have been designed to unify all the joke systems into a single joke system that eliminates the _really_ bad jokes.

        Anyway, back to the trucks ...

        At an individual level "megacharging" on such a large pack won't be a big deal since the 85kWh packs are already charged at up to 120kW. In bunches it's just a matter of scaling up. . As long as the use were steady the economics would be good.

        In terms of "burden" on the grid:

        2014 freight miles by truck were 1,996,165 million. (1)

        2016 US utility-scale electricity generation was 4.08 trillion kilowatthours (2)

        Using those numbers and wildly guessing at an average load of 20 tons, at 2 kWh/mile making all US truck freight electric would add 4.89% to US electricity demand. Not too bad.

        Regenerative braking is essential if the economics of electric power are to be realised in everyday stop-go driving on real roads.

        Basically, when braking the motor acts in reverse as a dynamo and charges a supercapacitor. When accelerating, you drain the supercapacitor before drawing on the battery. In F1 racing the system is called CURS.

        Also, you won't even need to use the brake pads unless braking sharply, as the dynamo exerts its own very effective braking force, so you greatly reduce copper and/or asbestos pollution of the roadside.

        How good the Tesla toys are at that depends on how good their designers are, but if F1 can do it routinely I don't see why Tesla can't.

          Re: Tesla semi?

          The issue with regenerative breaking we have found is that you need really, really big super capacitors, which are physical big and expensive. Batteries can't take charge as fast as breaking produces it and a fully laden truck will produce a great deal of current indeed under breaking. You can then charge the batteries off the super capacitors so as to leave them empty for recharging next time you break, if you're doing this for range (as we were) rather than speed (as F1 does). People generally use big resistors (which need cooling) to dump any current that doesn't fit in the capacitor.

            Kerse you, Red Baron!

            To reply to another post, of course stopping from speed will soon fill any sane supercapacitor and, if you don't divert the current, you will then get no more regenerative braking. So the system needs to be smart enough to understand that and adjust mechanical braking accordingly. But that is not my point.

            Most braking time is spent easing back gently for corners or other traffic hazards. Not spectacular amounts of energy on any given occasion, but repeated many times during a typical journey. It is this persistent low level of expenditure that regenerative systems can most easily recapture.

            1. ilmari

              Re: Tesla semi?

              The batteries should accept charge at the same rate as the stated acceleration, so 100 to 0 in 20 seconds. That seems like very aggressive braking under normal circumstances.

              Likewise, if it can maintain a specific speed going up a hill, it can maintain the same speed going down the hill without the use of friction braking.

A lot of truck fires are started by the brakes getting so hot that they set light to trailer. This is why truck drivers are trained on "stab" braking and the use of Jacobs brakes (engine braking through making a number of the engine's cylinders act as air compressors to slow the truck).

            Although I didn't read the entire site, I suspect the primary difference is that the truck doesn't require the overhead wires, it uses them where installed and possibly also charges it's own batteries from it at the same time. I wonder what the load capacity would need to be for a line of lorries as often happens? Maybe they need the smarts to stay away from each so there's never too many on one segment? I can see how this might appeal (barring any other obvious drawbacks) but I suspect any change to this sort of electrification would also require a change in attitudes across the entire haulage industry and a lot of co-operation between hauliers and their customers. JIT deliveries would have to be very, very carefully scheduled.

        The overhead power lines are there so that you can firstly avoid the cost of having to transport the batteries and secondly avoid the energy losses associated with charging and discharging batteries, because once you 'fix' the location of the batteries, it is relatively simple to remove them totally from the energy supply chain.

You are already splitting the load at this point, so there is limited additional handling.

          They can barely make thousands of the simple model 3, what makes you think they'll ever be able to deliver on the trucks in enough volume to not lose money on the whole thing? Tesla is bleeding cash at an alarming rate, and they have to either figure out their production problems or they'll end up bankrupt before the planned release date of the truck. Preselling model 3s via a deposit scheme to get cash up front was a clever scheme but the jig is up on that one, so they need to either start delivering on promises or some of those model 3 preorders will be canceled and they'll really be in trouble.

          I'll bet that those demo trucks were mostly a shell and pretty rough underneath the covers. To have a proper deliverable vehicle in 2019, they need to have a dozen or more trucks on the road being driven hard every day right now. It's going to take a couple of years of all weather driving and breaking things to get it ready for production. They will also have to get premises to build them, make tooling, create testing jigs and on and on. A company such as Navistar already has facilities, experience and legacy components to draw on and Tesla will need to come up with all of that from scratch. There is also the matter of certifications so they will need some pre-production units that can be destroyed and possibly more if the design changes substantially.

If they were part of a real car maker, Tesla could use the existing well established sales and logistics capabilities, and solve some of their immediate problems and reduce the SG&A costs.

        Tesla Corporation is certainly a financial black hole as it operates now, and if investors, Musk or the government don't bail them out, the company would go into Chapter 11 administration, and immediately be bought out. I suspect there would be a huge bun fight to see who would get to buy them, but I don;t think we'd end up there. Realistically, Musk would try and take Tesla private again before that happened, and either finance the continuing losses from his own pocket, or more likely do a quiet refinancing with a suitable private equity investor. The PE investor would take a big stake, but demand the right to take over most aspects of operational management. They'd then de-Musk the business operations, leaving Elon to be CEO in name, but more CTO by nature.

        Maybe Tesla Corporation will go bust, but my expectation is the private equity buy-in. Either way, I'll wager the product and the brand will be with us for a few more decades yet.

          Hardly, They have about half a million pre-orders for the model 3. All they have to do is announce a new vehicle and open up a website and people were queuing to give cash to product that wasn't even being built or had a full specification.

          The issue they have is that they can't get the car produced quick enough so the cash they are burning through is not being replaced with sales coming in because they don't have a model to sell. If they sort their production issues out smartish and (this is a big and) the price tag allows for enough profit then they'll be sitting pretty. Don't sort the production out or each car becomes a lot more expensive to produce than first thought and they'll have problems.

            They don't seem to understand how hard it is to be a car maker. As soon as they've got the Model 3 out and working, they will need to revisit the now ageing Model S, which in design terms is now a rather elderly seven years old. That'll need more R&D, more SG&A (but still need expensive logistics and after market support even when they've stopped making it).

        The obvious solution is to make batteries easily swappable.

        That way an electric equivalent of a "petrol station" would just be offload your nearly empty batteries, take onboard some fully charged ones.

        Could have the whole recharging of batteries going on at specialized power plants allowing high throughput charging (limited by batteries safe charging limits), and just a bit of logistics collecting "empties" and distributing "fulls" (in much the same way petrol tankers service "petrol station"s).

        That would need joined up thinking and (range of different) predefined battery dimensions and connections between competitors, so not imminent): But there is a need for "instant" power top up (where "instant" = not much different than "petrol station" fill up duration) to avoid irritated delayed people.

      EU trunks have a maximum TOTAL length of vehicle, so Cab+ Trailer. The idea is that you would get stupid long trucks suitable for some countries, but useless in others. The knock on effect of course, was small, flat cabs, and long trailers.

      The safest speed is slightly above the posted speed limit. A maximum speed of 60 MPH is not safe on a 70, 75, 80 MPH highway. Driving slow makes people behind you impatient and angry and thus you will do things you might not usually do in your rush to pass. These vehicles need to be able to drive highway speeds.

      Other than that, I like this. If enough recharging stations are available, then the 30 minute wait for trucks isn't a big deal like it is for passenger vehicles. Truckers need 30 minute breaks to stretch the legs and to help prevent drowsiness.

      Funny you should say that I was helping set up two different retail shops (for the same parent company) situated about 200 yards apart on the same road. I was waiting at the second shop for the truck to come from outside the first but there was no movement. Walked up there given I had equipment, cabling etc. in the back and asked why he wasn't moving. He said he had to have a rest period as mandated in the law and this was it. Asked whether he could have taken the rest period after driving the 200 yards to the other store but not he couldn't. So I told people to take their lunch immediately because he even wouldn't open the back of the vehicle to allow us to move stuff ourselves. At another store they were waiting for a truck that was held up because of driver rest periods. He hadn't got in to the rest stop until 9pm (11 hours rest) and therefore hadn't started driving again until 8:30am after breakfast. He was supposed to be there at 9am and had actually arrived an hour and a half late. delaying the start of fitting out. Therefore 11 hours should be plenty to recharge the batteries of both Tesla Truck and Driver.

        Of course it will. You are overestimating the requirements of the grid. Firstly the amount of electricity to produce petroleum is quite high, varying figures are mentioned but it is between 50 and 90% of that required to run an electric car in the same distance.

        Then you have the fact that many electric cars can charge overnight when little electricity is in use (cheap night tariffs, timer switches or smart electrical networks).

        Then small gas powered, nuclear or even large scale renewables could cover the rest.

        So you have the power sources sorted, the actual infrastructure can gradually be upgraded as required. It isn't that difficult to upgraded a substation or increase the UHV cable capacity. As long as it is gradual and not required in 5 years time. It's only a bit more difficult than getting FTTH for everyone.

        However with vehicles able to do 300 miles per charge and the average (UK) mileage of 7,900 miles p/a this would mean that a car would only need to charge on average twice a month. So the simultaneous charging will be spread out. Many cars will also be charged at service stations as well, with high speed charging and dedicated substations and electric supplies.

        I'm pretty confident that there will not be an electricity problem (in the UK at least ) with the gradual introduction of EVs up to 2040 (when no more petrol/diesel can be sold).

          Some unquantified caveats there. Having watched the progress of the build of an additonal feed from an offshore wind farm into the National Grid the progress is very slow. Infrastructure seems to be (quite sensibly) underground these days and a new link has to go through/past existing infrastructure which all takes time and planning. A lot of time seems to be taken up by archeology along the chosen route. You could of course just cover the whole country is a massive web of pylons and overhead cables.

          Yesterday's news, I'm afriad. Eaton announced an alliance with Nissan at least eighteen months ago to repurpose end of life EV batteries as static storage, and they aren't the only ones.

          Unfortunately the problem is that all the static battery system design, case, control gear, packaging, certifications, QC, assembly, warranty, installation, sales and marketing costs are the same when using second hand cells as using new cells. So you end up with a modest cost saving on the cells, that in a typical domestic storage system would be about 30% of the total cost, saving you perhaps 3-7% of the net cost on a competing brand new system. That is so small that there's no real merit in putting up with some cells that (even with a warranty) have been given a good thrashing in automotive applications. You call it previously loved, but that's a fine euphemism - traction applications are brutal on batteries, because they demand very high current.

          In larger commercial arrays the downsides and small cost savings might make more sense, but realistically it will be preferrable to recycle end of life batteries for the lithium rather than try and eke out their use for a modest cost saving. Also, although most grid arrays are currently lithium,. the chances are that as grid scale battery technology matures, other chemistries will prove preferrable.

        The cost of fossil fuels will need to treble at least before that happens, even though the cost of wind and solar has essentially bottomed out thanks to subsidies encouraging build out. The problem is the chained inefficiencies of renewable power to gas are very low, particularly because in the most obvious form, of dissociation of water into hydrogen, there's very low value in the oxygen, so it is released, and immediately you lose about a third of the energy of the molecular bonds you've just broken. Then you've got compression losses (for storage and transport) and decompression losses - individually not huge, but the chaining of inefficiencies is a real killer. There's further small losses if you are practical and decide not to fart around with H2, and methanate it to give you CH4 (obviously that's a whole lot easier to handle and use). If you can distribute by gas pipeline you lose about 1.5% in transit losses and system use, and then you'd have the modest efficiency of a spark ignition gas engine, similar to a modern ICE engine. You'd be lucky to see 15% end to end efficiency.

        All of which amounts to saying that you'd need a vast number of wind turbines to power any fraction of your road fleet. I did some fag packet maths, and an artic uses about 50 MWh of energy a year, and so the 120k artic tractor units on UK roads are going to need about 5 TWh (allowing for 20k truck out of the active fleet but registered). At 15% end to end efficiency, that gives you a need for 33 TWh of generation. That would mean that merely to power articulated HGV tractors via wind power to gas, you'd need all of the existing UK wind power fleet, and you'd then need to double it.

        You could perhaps use desert locations for truly vast PV arrays (with certain practical problems), but you'd then factor in either further losses - electricity transmission to Europe of around 10%, or 25% if shipping liquified gas via tankers. ICBA to do the maths, but I suspect that a desert array to power Europe's vehicles would be big enough for the albedo of the panels to be climate altering.

          In some situations it's possible to imagine closed loop systems that produce CH4 from excess power and use it as storage instead of batteries.

            The system problem is that while the excess power from renewables is sufficient to drive wholesale prices briefly negative, the actual volume of energy concerned that we might regard as excess is pitiful compared to aggregate demand. So "power-to-gas" becomes an expensive way of storing fairly small amounts of energy. I can see that it could work (and may have to work) for high value applications like synthetic aviation fuels, but keeping people's Xboxes and TVs running, I really don't see that being commercially viable.

Water is pumped up to a high reservoir when there is surplus power (from wind mostly) and let out through a power plant when needed. Batteries convert electrical energy to chemical energy and back.

      I would not want to be the first driver to run out of electrons a few miles from a charger because they'd used too much power taking off from traffic lights which can be almost every block in US cities.

              That is not such a big issue.

              Think back to the early days of the railroads (especially in the USA). Railroad stops were built at regular intervals, usually in the middle of nowhere, so the steam engines could take on more fuel and water.

              Retro, but regular truck stops surrounded by massive solar farms could solve that problem and also provide facilities for other travellers including tourists.

              Just look back to when locomotive fuel was less energy dense.

              1. Dave Bell

                Re: Sport truck! 0-60 in 5 seconds SA to WA

                There's a similar infrastructure problem in the UK. The old-style transport caffs maybe don't have room for solar panels, and electricity supply could need a big upgrade, but they were all over the place. Many have closed. Most of the time, all you see are places similar to a caravan in a lay-by. There were operations of the "Little Chef" sort that have mostly gone. Part of it is the motorway network, and in the years when I was doing long-distance driving, that sometimes felt like the only practical choice to be sure of a break.

                It's not as if you can pack sandwiches to recharge a truck. And I know of many petrol stations that have gone.

                General use of electric vehicles is going to depend on changes to the infrastructure. When "Top Gear" did a challenge on electric vehicles, it was hard finding places to recharge, and they maybe made a bit too much of a joke out of it. That's something to think about, something that maybe needs a new report. But I hope it has become too boring for "Top Gear"

                A lot of what I am seeing suggests this Tesla truck will struggle to cope with the long-distance trucking in America, but it might work a lot better in Europe, and in parts of the USA with high population-density. And there is an American Myth of the open road trucker which feeds into the criticisms.

                And have a look at the delivery trucks in cities, not the long-range semi-trailer rigs.

      You'll also note the lack of sleeper-cab option. The Tesla isn't designed for people who want to do 1,000miles on a tank cross-country or Trans-America. It's designed for taking 80,000lb from a factory, port or distribution unit to an Amazon fulfilment depot.

      Given that most of the US population live within 500miles of the coast, it follows that the majority of freight is travelling less than 500miles from port to destination (or from factory to port). And that doesn't count on the fact that maybe Tesla don't actually care about the US. European routes will lap this up. Trucking containers from Rotterdam to Paris? Trolling containers around Paris from a railhead? There is lots of inter- and intra-city work that this truck can do emissions free.

      If the TCO works out as Musk predicts then this will be a roaring success (and it shouldn't be hard, because TCO on a diesel is a total pig - Fuel, regular oil changes, clutches, wear and tear on mechanicals).

      Amazon will love these for transfers between logistics hubs, as will the USPS and the likes of UPS/FedEx for moving freight from an airport to local/regional distribution hubs.

      The target market for these doesn't call for more than 500miles between stops, and users will install megachargers at their depots/warehouses so you charge whilst you (un)load.

      The initial users are going to be fleet buyers who can also install the appropriate infrastructure at their end-points. Not owner-operators.

      We've got a major agri-feed business down the road from us. They run their own fleet of 25+ Class8s hauling tonnes of feed to farms. At night, every one of those trucks is back in the yard. You think they need a second driver or do more than 500miles a day? Plenty of people need heavy or bulky stuff moving short distances.

      The long-haul crowd saying "This is useless, I can't team-drive across America in it" are being deliberately obsequious. Most people don't need or want to do 1,000 miles on a tank.

    Orphans?

    I'd be interested to know how the convoy idea would deal with mundane things like slip-road roundabouts, junctions and traffic lights?

    Get two or three semi trailers in a row, and then have to make sure you can get them all through said obstacle before the lights change or someone else with right of way comes along and splits up the convoy? Then all the fun and games of the leader having to slow down or stop to let the trailing drones catch up again and reform the convoy, around a busy area? What could possibly go wrong? It's hard enough to do that sometimes with a meatsack-driven convoy of cars, let alone autonomous lorries.

    Not to mention the far end fun when multiple lorries arrive at once in convoy and the loading docks of the destination have to deal with them all at once?

    1. mosw

      Re: Orphans?

      The convoy idea is intended for roads like the US Interstate highways where you can drive for 10 hours without stopping if your bladder is big enough. They would also be ad-hoc in that any Tesla semi could join or leave the convey at any time. The trucks in the convoy do not have to have a common destination. The advantage of a convoy is lower aerodynamic drag and less stress on the driver.

    Yes, some are long-distance hauliers and range is important.They can continue to buy diesels.

    But there are many others who have trucks that are used all day every day on multi-drop deliveries that get nowhere near the proposed range limit of the Tesla. RHA figures for 2016 gave fuel costs for a 44-tonner at 48-54 pence per mile. The cost of a battery recharge will be half that. They'll sell like hot cakes.

      "Aaaaaarrrgrghhhh! Will you lot PLEASE stop focusing on the range. Hauliers don't buy trucks based on range they buy trucks based on lifetime cost per mile."

      The upfront price will be a huge factor too. These will not be cheap and there is a cost to service the financing. A more expensive truck will be more expensive to insure. All of the proposed safety tech won't mean a thing to insurance companies until they can look at real data and it proves itself to be true. Service costs will also be a factor for insurance. Tesla is very expensive when it comes to parts and service outside of warranty. If a comparable repair is 3x more for a Tesla than a Kenworth, that will just raise the cost of the insurance. Little things will still go wrong on a vehicle that is driven all day every day that aren't covered under warranty. Can a company get those parts quickly or will there always be a long wait. Will there be unreasonable entanglements that require that a factory technician does certain repairs to be able to get the replacement parts?

      TCO is a valid argument, but ROI over time is as well. If it takes 10 years to break even with costs compared to an equivalent diesel truck, why would a company buy a Tesla and have to possibly spend another large sum of money to install charging infrastructure? Will Tesla still be around 10 years after the purchase and still supporting ten year old trucks? It's a big gamble that they will unless things change radically over the next couple of years.

    Notice how there's no price mentioned.

    Given that a used IC semi costs $80K used - which is roughly the price of your Tesla sedan, how much would the Tesla semi cost? $500K?

    As for 20% more efficient - it would be interesting to see just how much difference that makes vs the operating cost. 10 MPG is considered good for a semi (fully loaded). Assuming 60 hours/week, 50 weeks a year, 60 mph average, $3.50/gallon - the operating cost for an IC semi might be around $18K a year. 20% savings on that would be $3.6K. Triple that for maintenance and what not - $10K.

    $10K savings per year if the vehicle costs 4x or more the price? Non-starter.

    1. mosw

      Doing your math, I get:

      60 hr/wk * 50 wk/yr * 60 mi/hr * $3.5/gal * 0.1 gal/mi = $63,000 /yr

      $63,000 /yr * 0.2 * 3 = $37,800 /yr in savings

      1. c1ue

        The tripling was to represent likely maintenance and other costs which are roughly $8k/year for a normal truck, so I've been told.

        So the savings would be 20% of ($63k+$8k) rather than 20% of $63k * 3.

        Or about $14k.

        Even if the savings *were* $37k, it still would not help since the interest on an enormous $500k loan would eat it up.

    Elon continues to dupe the gullible with sideshows that may never even come to fruition as they can't even deliver the Model 3 which they have banked on to make them profitable. Musk claimed they would be producing 30,000 Model 3 vehicles by Dec. 2017 though he can't explain who would actually buy these vehicles as they have trivial vehicle deposits. GM has projected sales of it's Bolt EV at 35,000 annually. Even though the Bolt is priced around $35K in the U.S. sales are poor as there simply aren't many people foolish enough to buy into the meritless delusions of EVs which are impractical for 99+ % of the world.

    Some folks seem to believe that electricity is free but I haven't found any place where that is true. In addition the EV batteries are not lasting 10+ years as predicted. They are needing to be replaced in as early as 5-6 years with a cost of ~$14,000 U.S. When do the math EVs simply don't add up for most of the world. Anywhere that sees very hot or cold weather makes the range on these EVs drop close to 50% when heating or A/C is used. Hydrogen fuel cell tech is the only practical solution for an EV but refilling stations would need to be added. You can fill the tank of a fuel cell vehicle in about 5 minutes and get 300+ miles without issue from all current fuel cell cars.

    Or does that front end look like an upside down T?

    No doubt all about streamlining for wind resistance.

    Chris Eubank's gonna love this

    I can see the appeal, riding high above mere SUVs and tanks... imagine all that electrical torque goodness without the heavy bodywork and wheelbase, replaced with a light sporty shell, sports gearing.

    Internal combustion morons will be proven wrong

    Wait and see people, vehicle electrification is on it's way. Ranges are getting better. Soon there will be no good reason to be driving an internal combustion engine piece of crap. Tesla has already proved how outdated and outmoded it is. I have a LEAF that only has a 80 mile range and it's working for me. The Bolt is around the same price point now and has a 240 mile range. I love the way people are starting to wake up now. There are still naysayers. Everyone is an expert engineer and know better. Too bad they are getting proved wrong. Or, maybe the oil company shills have just been shamed and gave up. I also think it's funny that even companies like GM are talking up their electric vehicles now. Now that China has said that they are banning ICE vehicles. As always, it's all about the $$$$.

      Soon there will be no good reason to be driving an internal combustion engine ... . Tesla has already proved how outdated and outmoded it is.

      Tesla et al have yet to demonstrate anything that can convert 50 litres of fossil fuel into something more capable than a Ford Focus for example.

      I suspect, given the electricity supply math's and logistics, truck stops will be running massive diesel generators to create the electricity needed to recharge the batteries. Which raises the question: is it better to burn fuel directly in a vehicle or burn it remotely and incur all the conversion and supply losses.

      Interestingly, once you take into account the energy conversion equations and costs, you will see that economically the cost of recharging your vehicle has to increase to better reflect the cost of the fossil fuels used to generate the electricity...

    .. if they allow the driver to charge his or her phone it'll take miles off its range ..

    People will buy a Semi EV - won't be Tesla

    I've had to write a number of rather dull papers on competition in trucking, and have had the pleasure of knowing a few people who drove and owned semis for a living.

    About 40% of truck sales go to people running one or two vehicles. They buy from a particular supplier almost entirely based on service for their particular area. Most drove Scania if they where picking up the tab and when (with my economist hat on) I asked what would be a substitute, they all responded with some variant of "I'd do something else other than drive a truck".

    Unless Tesla can offer something that can beat a Scania (or equivalent, eyeball your local truck park) for loyalty and service, they won't find many people willing to lease them. If they are suited to a hybrid or an EV, then they will wait until Scania brings it one out.

    Tesla isn't the only one with the ear of governments. I would have also hope Musk was a good enough engineer to recognise a great piece of pre-existing art and re-use it. Trolley trucks for the future :)

    Checked with a pro, got a "No!"

    Decided to ask a contact who actually runs a truck fleet, would he buy the Tesla truck? Surprisingly, he didn't have a problem with the short range, they run many "day cab" routes which are under 500 miles, but he said he wouldn't buy a truck with a central seat as it was dangerous. He explained that half his fleet's accidents are backing accidents, and the way they train their drivers is to back with the cab at an angle to the trailer, to the left (US), so they can see where the trailer wheels are. A central seat would make this impossible. He said to look on YouTube for "45-45 backing" to see what he meant. It seems Musk really didn't check with a trucking pro.

        Re: anonymous boring coward Re: Checked with a pro, got a "No!"

        "Cameras and monitors..." Pro still said no. Actually, first he just laughed at that idea, then he said an emphatic no. He explained that, when a driver is looking over his shoulder to judge where his "tandems" (trailer wheels) are, he is actually doing a complex 3D problem involving looking where the tandems are in relation to the "reference point" (the point he has to turn round to get into the spot, usually about ten feet out from the closest side of the parking space), where the tandems are in relation to each side of the "gate" (the entry to the parking space), the angle of the trailer direction relative to the sides of the parking space, and the angle of the cab to the trailer (and probably also forward and down to check which way his front wheels are pointed). That's not going to work on cameras.
