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.

U Toronto study measures GDI emissions in urban near-road environment

Green Car Congress

A study of emissions from gasoline direct injection (GDI) vehicles in an urban near-road environment in Toronto over a wide range of weather conditions (February 2014 to January 2015) found that—other than for NO x and CO—the GDI engines had elevated emissions compared to the Toronto fleet.
