49g/km
This shows how stupid the NEDC test is, and how good manufacturers have become at "gaming" it for low taxation. This now happens with all new cars but it's ridiculous in the case of hybrids.
All the car's CO2 comes from burning fuel in the engine, therefore fuel consumption in litres/100km must be proportional to g/km if the two are measured under the same conditions. But it never is these days, not in the official figures. A 32mpg car actually emits over 200g/km (you can do the maths if you like) and should be liable for fairly hefty VED, not a free tax disc.
There are now millions of cars on the roads, mainly turbo models and hybrids, which are paying very low rates of VED yet producing just as much CO2 as older or more conventional cars which are taxed more heavily. And the direct injection petrol turbos have atrocious PM10 emissions too, so they're giving your kids asthma and cancer.
It's all gone mad.
