But generally even with the weight cars are WAY more fuel efficient. There are some fords (non-hybrids) approaching 3 litres/100km. Even mini-vans that get 7-8 litres/100km. When 15-20 years ago a 3 door hatch back would be 6-7 litres/100km... So I don't really see your point. Yeah cars are getting heavier, and engines are getting smaller and more efficient.
