0VW confirms XL1 plug-in hybrid car
Volkswagen Group has just confirmed that will build the XL1 plug-in hybrid, which the automaker says will be the most fuel-efficient production car in the world. The two-seater uses a diesel hybrid powertrain, an aerodynamically shaped body and lightweight materials to limit fuel consumption to 0.9 liters of diesel per 100 km. It has CO2 emissions of 21 grams per km.
The production XL1 closely resembles the concept VW unveiled in early 2011. The aerodynamically shaped body includes fully covered rear wheels and rearview mirrors integrated into the door skin. The XL1 makes extensive use of carbon fiber-reinforced plastic for the body panels and aluminum for the frame structures. VW says the car has a curb weight of 795 kg.
The plug-in hybrid powertrain combines an 800-cc, two-cylinder diesel engine, rated at 47 hp, with an electric motor rated at 27 hp. Power flows through a seven-speed dual-clutch transmission. The XL1 has a lithium-ion battery pack under the hood. The car can travel up to 50 km on electric power. VW says the XL1 needs just 8.3 hp to cruise steadily at 100kph. It has a top speed of 160kph.
