Fossil-fuelled spark ignition and diesel engines will continue to dominate the automotive market through 2020, despite public and private efforts to develop new sources of automotive power, according to a study jointly carried out by consultants DRI-WEFA and Arthur D. Little. The forecast for the continued reliance on fossil-fuel power for automobiles takes into account advances in fuel cell research such as the Bush administratiocn's announcement earlier this month supporting the development of fuel cells through its "Freedom Car" initiative.
