Volkswagen XL1 to become the world’s most fuel efficient production car ever

Volkswagen XL1

Entering the 200+ mpg segment, Volkswagen is all set to produce the world’s most fuel efficient production car dubbed the “Volkswagen XL1” that is claimed to achieve 261 mpg (European cycle), owing to the reduced weight, better  aerodynamics and wrings. Slated to be displayed at the 2013 Geneva Motor Show next month, the production version of the XL1, which is an enhanced edition of the 2009 L1 and original 2002 1-liter bubble, makes use of a 0.19 drag coefficient to become the most aerodynamic production car till date.

Covering the rear wheels and replacing the mirror with rear-view side cameras achieve better aerodynamics, the XL1 features a thin-glass windshield, polycarbonate side windows and  body, together with the monocoque structure and body panels, finished in carbon fiber-reinforced plastic (CFRP) to bring its weight down to 1,753 pounds (about 795 kg). Measuring 153.1 inches in length and 65.6 inches in width, the XL1 generates power from a 47-hp 800cc two-cylinder TDI engine, 27-hp electric motor and lithium-ion battery.

Featuring a compact rear-wheel-drive powertrain, the XL1 includes a seven-speed dual-clutch gearbox (DSG) to achieve up to 32 miles (about 50 km), thanks to plug-in hybrid powertrain, of all-electric driving. Cushioned with double wishbone suspension upfront and a semi-trailing link suspension in the flipside, the XL1 also incorporates aluminum suspension mechanism, magnesium wheels and ceramic brake discs to ensure lightweight organization.

Moving on Michelin low rolling resistance tires, the XL1 makes use of just  just 8.4 hp/6.2 kW to maintain a steady speed of 62 mph (100 km/h), while it covers 1 kilometer (0.62 mile) on just 0.1 kWh of electricity in all-electric mode. Capable of reaching the top speed of 99 mph (160 km/h), the Volkswagen XL1 can accelerate from 0-62 mph (100 km/h) in 12.7 seconds only, as the electric motor kicks in to assist the diesel engine for instant acceleration. Replacing the 1+1 layout of the L1 prototype with side-by-side seating within, the XL1 allows entry to passengers through two winged, double-hinged doors.
