One of the challenges facing automakers around the world, is whether to use gasoline or diesel motors in their hybrids. As R & D budgets shrink throughout the car world, are there budgets to fully research new innovations?
BMW at the 2009 Frankfurt Motor Show earlier this month, revealed their M sports car concept that features plug-in-full hybrid technology powered by a total of 3 sources. A 3 cylinder turbodiesel rear engine, along with a hybrid synchronous motor at the front, and a full hybrid motor at the rear, (positioned between the turbo diesel and the double clutch transmission). Advanced Brake Energy Regeneration is stored in 98 lithium polymer cells. A plug-in connection is used with a conventional power source, charging the lithium polymer cells in 2.5 hours at 200V, 16A. A higher power source will reduce the time to as little as 44 minutes. The underside of the concept is completely closed to to avoid drag that can increase fuel consumption, (especially important at 155 mph). This is BMW Vision EfficientDynamics, combining the performance of a BMW M, and the emissions and economy of a smaller car. BMW brilliant!
