In an extensive interview with the Automotive News, Christopher Grundler, director of the Environmental Protection Agency’s Office of Transportation and Air Quality, said that the auto industry is ahead of schedule on meeting the Obama administration’s new fuel economy standards that mandate a nominal average of 54.5 mpg (according to CAFE calculations) by the year 2025.
Take One: The Ruf 911 Greenster EV. From AB Green’s report:
Last fall, Porsche high performance tuning specialist Ruf announced that it had built a prototype electric sports car called the eRuf which was essentially a lithium ion battery-powered 911. That was just the beginning of the story as the company has brought the Greenster here to Geneva. The Greenster is a targa top 911 in the old style with a chopped speedster type windshield. In the back sits a 270 kW Siemens electric motor with 695 lb-ft of torque. The battery pack system has been improved and is now 30 percent smaller in volume, restoring the front trunk space that was lost on the original. The battery pack now has greater power capacity allowing it to release and absorb power faster, enabling more regenerative braking capacity. The battery can apparently be charged in only one hour from a 400V outlet. The next iteration will switch to a twin motor setup and the company is planning a small series production run in 2010.
Porsche 911 have been a favorite target for EV conversions fir decades. Ruf’s version is almost series ready. It will probably have an EPA mpge rating similar to the Tesla’s 256 mpge. How many would Porsche have to sell to increase its fleet average to the amount necessary?
