For Lightweight Diesel Plug-In Hybrid, 261 MPG Is ‘a Reality’

Volkswagen has proclaimed its two-seat carbon composite XL1, which is to enter production at Osnabrück in Germany, as the world’s most efficient car, as the combination of lightweight structures and a lithium ion battery-powered plug-in hybrid electric drive yield a European combined fuel consumption rating of 261 miles per gallon.

Volkswagen reports 261 miles per gallon for its XL1 diesel-fueled plug-in hybrid electric vehicle.

“At 261 mpg I would fuel once a year in New York City, twice a year in California,” says one cross-country commuter we know.

Volkswagen new KL1, however, will be offered only in Germany in Austria. It will employ lithium nickel manganese cobalt oxide batteries yielding an all-electric range of 32 miles. The XL1 will meet Euro 6 diesel emission limits using SCR (selective catalytic reduction) and a particulate filter.

“The XL1 is an automotive standout that follows pure sports-car design principles,” VW says. It weighs just 1,753 pounds, has a drag coefficient of just 0.19, and a low center of gravity. “This super-efficient Volkswagen thus has the ability to cruise down the road at a constant 62 mph while using just 8.3 horsepower. In all-electric mode, the XL1 requires less than 0.1 kilowatt-hours to cover more than a kilometer.”

‘Almost Like a Conventional Vehicle’

The XL1 has a 47-horsepower, two-cylinder Volkswagen TDI diesel engine, a 27- horsepower electric motor, and a seven-speed DSG dual-clutch automatic transmission. “The 261 mpg fuel consumption figure is a record that has not been achieved by any other vehicle to date, showing that Volkswagen is redefining what is technically feasible in the automotive industry,” the automaker says.

The XL1 has a top speed of 99 mph and can accelerate from 0 to 62 mph in 12.7 seconds.

Unlike prototypes shown in 2002 and 2009, with driver and passenger seats in a tandem arrangement for optimal aerodynamics “in the XL1, the two occupants sit slightly offset, side by side, almost like a conventional vehicle.”
