Study finds that increased vehicle travel and decreased occupancy have undercut the impact of improving fuel economy over last 40 years

Green Car Congress

Sivak found that while the vehicle fuel economy of the entire light-duty fleet improved by 40% (from 13 mpg US to 21.6 l/100km), because of the decrease in vehicle load, the occupant fuel economy only improved by 17% (from 24.8 Combining these two effects yields a reduction of about 14% in the amount of fuel used.

GFEI report suggests $2T savings from fuel economy improvements in ICE vehicles through 2025 can help fund long-term transition to plug-ins

Green Car Congress

Increasingly efficient conventional combustion-engine vehicles will be key in moving towards a low carbon future, according to the GFEI. Far better fuel economy from cost-effective conventional technologies can keep fuel demand steady and save close to half the CO 2 emissions from cars by this date.
