Re: Someday soon all cars will be like this (or worse).
"Cars may get more efficient, bit actually they are getting more powerful."
The reality is that "efficiency" is a nebulous thing anyway - an internal combustion engine is at maximum efficiency at full load and under normal day-to-day conditions it's more like 2% than the 35% theoretical maximum for an otto engine.
There's still a LOT of room for improvement and this is why a well-balanced sports hybrid can blow the doors off a "muscle car" whilst still returning economy figures in the mid 30s.
The problem at the moment is that the hybrid package still costs too much up front to be usable down in the economy-car segment, which is where it's needed most.
