THE 2010 PORSCHE TURBO!

The face-lifted 2010 Porsche 911 Turbo will debut at the 2009 Frankfurt Auto Show in September, the German automaker confirmed on Friday. Porsche, uncharacteristically, is putting the emphasis on the 911 Turbo's fuel economy, saying in a statement that it "continues to create more from less."

However, the car's actual fuel economy remains a mystery, since neither Porsche nor the EPA have released any official numbers. The EPA says the 2009 Porsche 911 Turbo with a five-speed automatic transmission returns 15 miles per gallon in city driving and 23 mpg on the highway. In Europe, the 2010 Porsche 911 Turbo averages 21 mpg under the EU5 standard.
