After years of development and previous designs, Volkswagen unveiled its contribution to the green revolution. The vehicle is called the Volkswagen XL1 Super Efficient Vehicle and was unveiled at the Qatar Motor Show.
The vehicle is the cutting edge construction technology of the German automaker. It features an advanced hybrid plug-in drive train in an all-modern body that allows the vehicle to have a mileage of 313 miles to the gallon and producing only 24 g/km of CO2 during its full travel.
Central to this vehicle is the compact 800 cc turbo diesel injected (TDI) two cylinder common rail engine fueled by diesel allowing it to produce 48 PS. Aside from the main engine, it has an electric model able to produce only 75 PS. These two engines are able to provide the proper power to propel the vehicle weighing only at 795 kg.
The TDI engine is joined to the electric motor with a seven-speed DSG gearbox mounted on an automatic clutch attached to each unit. This system allows for the two engines to work together when accelerating or independent of the TDI engine. When run on pure electric motor, the XL1 can run up to 35 kilometers before the diesel engine takes over. Acceleration from zero to sixty-two miles per hour can be achieved in 11.9 seconds and its top speed is 99 mph.
The XL1’s seating is the driver side beside the passenger seat in a body shell composed of advanced new materials providing low weight to strength ratio. The whole body weighs a mere 230 kgs. The material is Carbon Fiber Reinforced Polymer construction shaped into the car through a process called Resin Transfer Moulding.
Aside from the body weight, the drive train weighs in at 227 kg, the running gears at 153 kg, the bucket seats and the interior at 80 kg and the electrical system coming in at 105 kgs. The total weight is 795 kg where only 23.2 per cent made out of steel or iron. Other weight saving materials includes magnesium on the wheels, ceramics on the brake discs and aluminum for dampers, steering system and brake calipers.
Entry into the car’s cockpit is done through elegant scissor doors hinged on the car’s A-pillar and to lessen the car’s drag, wind tunnel tests were used making the drag coefficient only to 0.186. The length is 3,970 mm and width is 1,682 mm quite near the measurements to the Volkswagen Polo but the height is only 1,184 mm near the measurements of a Lamborghini Gallardo Spyder.
The Volkswagen XL1 remains to be a concept car for the company but it is the precursor of a new class of cars aptly named Super Efficient Vehicles.
