Is a clean car more fuel efficient?

Are big cars less fuel efficient?

Motorists are usually advised that smaller cars can travel more miles per gallon (mpg) than those with larger engines, making them cheaper and more environmentally friendly to run.

Is fuel efficiency associated with higher vehicle prices?

When looking at vehicles in the same market segment, with similar power and size, and with the same powertrain type, fuel efficiency is not coupled with higher vehicle prices. The 25% most efficient vehicles cost 5-7% less than the average equivalent vehicle, and the average fuel economy improvements they deliver are between 0.6 and 0.8 Lge/100 km.

Does fuel economy matter?

Fuel economy matters more than ever, so find the right vehicle for your needs that also sips gas better than other cars on the road.
