I think since 2010 fuel consumption has declined a lot even though weight has increased. So when manufacturers decrease weight, combustion cars will become even more environment friendly. For example: a big Audi nowadays can do 20-30 km/l. When losing a lot of weight it could even do more. Losing a lot of engine power maybe even more (there is hardly any need to go faster than 160 km/h). Edit: wow, reading a little into it: in 1899 a electric car was the first to break the 100 km/h barier. http://en.wikipedia.org/wiki/Electric_car http://en.wikipedia.org/wiki/Electric_car
