261 MPG VW XL1 Concept Car

The XL1’s hybrid system consists of a 47-hp, 800-cc two-cylinder TDI turbo-diesel engine, a 27-hp (20-kW) electric motor, and VW’s seven-speed DSG dual-clutch gearbox. (The DSG is programmed to operate only in automatic mode.) The TDI and the electric motor combine to deliver maximum torque of 103 lb-ft. This amazingly compact powertrain is mounted transversely behind the passenger compartment and drives the rear wheels. A 5-kWh lithium-ion battery pack and a 2.6-gallon diesel fuel tank are nestled between the powertrain and passenger compartment.

 

The major factor in weight saving was the use of carbon fiber for the chassis and body panels. The center monocoque/safety cell is molded in one piece by a rapid resin-transfer process that’s quicker and cheaper than conventional hand-laid carbon. VW developed it with the Austrian company Carbo Tech, which also helped implement a similar system for the McLaren MP4-12C supercar. The supercar connection doesn’t end there: The XL1’s supersmooth, aerodynamically optimized shape should achieve an extremely low drag coefficient of 0.19.

No idea what one will cost, but it will apparently be manufactured for sale. It is only a 2 seater, but the MPG is astonishing.
