A 235 mpg car, like the Volkswagen XL1, could be a dream car on the current market, but the problem is that the XL1 is too expensive and limited to just 50 units, with none of these units arriving in the U.S.

The good news is that the XL1->ke3758 could get a sportier, XR1 variant that could also arrive here in The States. The future XR1 would be built on the same structure as the XL1, but it would offer performance figures to rival the Porsche 911->ke282 for half the money.

If produced, the XR1 will use lots of carbon fiber to keep the weight down and will be offered with a powertrain that will deliver 70 mpg. Rumors suggest that the XR1 could get a 2.0-liter turbocharged four-banger and a turbo- or supercharged three-cylinder engine. No matter what engine is used, the XR1 will most likely use a seven-speed dual-clutch automatic transmission, will be about 230 pounds lighter than the XL1 and will offer a more conventional look.

First details suggest that the XR1 will sprint from 0 to 60 mph in about 4.5 seconds and will hit a top speed of about 190 mph.

Volkswagen XL1

The XL1 is powered by a hybrid drivetrain that combines a 48-horsepower two-cylinder TDI engine with an E-Motor that adds another 27 horsepower and a 7-speed dual clutch gearbox (DSG). This system delivers a fuel economy of 235 mpg, with 31 miles delivered in electric mode.

The model will sprint from 0 to 100 km/h (62 mph) in 12.7 seconds and can hit a top speed of 160 km/h (100 mph).
