The Volkswagen Up! Lite concept hybrid car, which VW says is capable of 70 mpg on the highway, had its world premiere this week at the Los Angeles Auto Show.

With its combination of a VW TDI clean-diesel engine, an advanced electric motor, and a seven-speed Direct Shift Gearbox, the Up! Lite is an innovative hybrid that combines several high-mileage technologies in a vehicle with room for four adults.

"Volkswagen aims to be at the forefront of every level of automotive design – from the creation of an idea all the way to consumer experiences with the final product," said Stefan Jacoby, president, Volkswagen of America. "The Up! Lite stands at the pinnacle of that devotion, as a clear representation of what we believe is the standard by which all other hybrid vehicles will be judged.”

At the heart of the Up! Lite is Volkswagen's all-new hybrid powertrain consisting of an 0.8-liter, two-cylinder TDI clean diesel engine and an electric motor that acts as the vehicle's starter, alternator and E-drive unit.

On its own, the small engine produces 51 horsepower and up to 88 lbs.-ft. of torque. The electric motor, with its 13 additional horsepower, can be used to boost the TDI engine as needed, provide regenerative braking and even propel the Up! Lite on its own.

The seven-speed DSG transmission ensures the driver has access to the full power range whenever needed, and it allows for a 0 to 60 mph run of 12 seconds, a top speed of 100 mph, and the exceptional highway fuel economy rating of 70 mpg.

The Up! Lite's efficiency benefits from lightweight aluminum and carbon-fiber elements, and an aerodynamic exterior that comes dressed in a unique Liquid Blue Metallic paint to match the car's fun and futuristic feel.
