Volkswagen showed the latest version of its super-high-mileage cars–and this time said it would put it into production. In testing the two-passenger car delivers 261 miles per gallon. It’s body is made of lightweight but strong carbon fiber and its plug-in hybrid powertrain combines a small diesel engine and electric motors powered by lithium-ion batteries.
The 2013 VW Beetle TDI is no longer that bare-bones icon of the Sixties nor the note-perfect cute revival New Beetle of the past decade. With the 2.0-liter turbo-diesel engine, the Beetle will regularly turn in 40+ mpg on the highway. The EPA numbers are 28 city/ 41 highway with the manual and 29/39 with the automatic. As is the case with most diesels, and in contrast to most gasoline-fueled vehicles, beating EPA fuel economy numbers are not hard.
