GENEVA — Volkswagen has introduced a Golf TDI Hybrid concept at the 2008 Geneva Auto Show. VW says the concept returns 69 mpg but emits less than 90 g/km of CO2, making it one of the most eco-friendly solutions to the twin issues of energy conservation and pollution reduction.
The Golf TDI Hybrid looks fully finished and virtually showroom-ready. VW says the car "is currently a concept vehicle, but a version is likely to go into production in the future."
In addition to a 27-horsepower electric motor, the key ingredients are VW's new seven-speed DSG dual-clutch transmission and a 1.2-liter three-cylinder common-rail turbodiesel rated at 74 hp and 132 pound-feet of torque. The electric motor, which makes 103 lb-ft, can power the car on its own at low speeds, and replaces the conventional starter motor and alternator.
The Golf TDI Hybrid stores energy in a nickel metal hydride battery pack. In addition, the diesel engine is equipped with a stop/start system that can shut the engine down at idle to conserve fuel.
What this means to you: We're still waiting for a diesel-hybrid response from Detroit — but it probably isn't going to happen. — Paul Lienert, Correspondent
