At the 2012 Chicago Auto Show, Volkswagen will reveal the most fuel-efficient version of the new Beetle in the States, the TDI, which is powered by a 2.0-liter four-cylinder diesel engine producing 140 horsepower and 236 lb-ft of peak torque. The same powerplant is offered on the North American Jetta and Passat TDI models.
The diesel engine can be mated to either a six-speed manual gearbox or VW’s dual-clutch DSG six-speed automatic, with the German automaker predicting a fuel economy of 29 mpg city and 39 mpg highway.
That's a significant improvement over the base 170HP 2.5-liter gasoline engine that returns an estimated 22 mpg city and 31 mpg highway with a five-speed manual, and 22 mpg city and 29 mpg highway with the optional six-speed auto.
