Volkswagen has announced pricing details for its 2013 Volkswagen Beetle TDI, the only clean diesel vehicle in the compact coupe category.

When it goes on sale in August, the Beetle TDI will retail for $23,295 in manual transmission form. With a six-speed DSG twin-clutch automatic, you'll pay $1,100 extra. All prices exclude a destination charge of $770.

The diesel Beetle joins the existing 2.5-liter naturally-aspirated and 2.0-liter turbocharged gasoline models, but buyers will get to benefit from the extra fuel efficiency that VW TDIs are renowned for.

No EPA figure has yet been confirmed, but Volkswagen predicts figures of 41 mpg highway and 32 mpg city with the six-speed manual. That would make it 2 mpg better than the Golf TDI in the city, but 1 mpg worse on the highway--no doubt owing to the less aerodynamic retro shape.

The 2.0-liter turbodiesel produces the same 140 horsepower and 236 pounds-feet of torque, and all models come with 17-inch alloy wheels, keyless entry, Bluetooth connectivity, SiriusXM Satellite Radio and eight speakers. Sunroofs, touch-screen systems and a Fender Premium Audio system are available on higher-spec models.
