The Asterion does not give up the traditional Lambo engine; there's still a 5.2-liter V-10 midships linked to a 7-speed dual-clutch transmission.
What's new is the addition of three electric motors; one to act as a starter-generator on the engine and two on the front axle, providing the all-wheel-drive serivce. The lithium-ion battery stored in the tunnel where the transmission would normally go has enough juice to carry the Asterion some 31 miles on electricity only.
The extra weigth of the electric system comes with the offset of not having a mechanical all-wheel-drive. Lamborghini says the combined system can produce 910 hp at max, enough to propel it to 62 mph in three seconds flat. And those batteries help give the Asterion a fuel economy roughly comparable to that of a Toyota Prius.
