What Makes It So Efficient?
Power will be provided by an 800 cc 48 hp twin cylinder diesel engine, essentially half of a 1.6 liter TDI motor. Both it and a 27 hp electric motor send power to the rear wheels via a seven speed DSG transmission.
Much of the car's efficiency owes to its aerodynamic design. The two seat XL1 is long as a Toyota Yaris and slightly narrower at the front, yet it's over a foot shorter. Much of this length is due to a long Kammback rear end, reducing air turbulence. The concept's gullwing doors will make it into production as they're all but required to get into this tiny vehicle. Like Tesla's Model X prototype, the XL1 will use cameras in place of side mirrors, further reducing drag while giving the driver a view of adjacent traffic via screens mounted in the doors. The end result is a 0.189 coefficient of drag, far and away the most aerodynamic production car ever built. A combination of an aluminum structure with carbon fiber-reinforced plastic body keeps the curb weight down to about 1,750 lbs.
0 to 100 kph (62 mph) should take 12.7 seconds with an electronically-governed top speed of 99 mph. The tiny 2.6 gallon fuel tank can let the car go as long as 700 miles between fill-ups, while the front-mounted battery provides an all-electric range of 22 miles. Final fuel economy figures are expected to be around 270 mpg, well past the 1 liter / 100 km goal.
