Volkswagen XL1 is billed as the most fuel-efficient production car in the world, deliering fuel economy of 313mpg (0.9 litres of diesel per 100 km) and CO2 emissions of 21g/km has not been much in the news lately. Limited to 250 units, the car is expected to end production soon and is a test bed for future technologies that we can see in future VW cars.
Volkswagen has many brands under its umbrella, including the iconic Italian motorcycle maker Ducatti.
The two have now joined forces for a very special concept called XL Sport, based on the XL1.
The XL Sport uses the world’s most powerful two-cylinder engine, the Ducatti Superleggera V-Twin engine with 197bhp that revs to 11,000rpm linked to a seven-speed DSG dual-clutch automatic transmission sending power to the rear axle.
As a result the lightweight XL Sport goes from 0-62mph in 5.7 seconds on its way to a top speed of 168mph.
The high-tech engine features titanium connecting rods, desmodromic valvegear, and magnesium-alloy components.
The XL Sport has also received a completely new chassis using a motorsports-derived features.
The XL Sport weighs 890kg and has the coefficient of drag of 0.258, which is not as efficient as on the XL1, but still quite amazing.
Other changes compared to the XL1 include forged magnesium wheels fitted with wider tyres, additional cooling ducts, pushrod rear suspension, optimizied underbody, rear diffuser and an extendable rear spoiler powered by the same unit as in the Lamborghini Aventador.
The interior is based on the XL1′s, boasting a digital instrument cluster that includes a lap timer and oil pressure display, as well as unique carbon fibre touches, aluminium touches, red seat belts, red decorative stitching and aluminuim-alloy shift paddles.
