Ferrari LaFerrari vs McLaren P1 vs Porsche 918 Spyder
Top Gear sizes up three of the most anticipated hypercars of 2013...

All three use seven-speed twin-clutch transmissions, all of them heavily adapted from the ones elsewhere in their maker's ranges. Then we get to the hybrid systems, and they diverge again.
The Ferrari always runs with the engine on. Combustion noise is integral to what it means to be Ferrari, they say. So the battery is a relatively small 60kg unit, and the hybrid system is all about augmenting the engine's character rather than fundamentally changing it. The motor switches to recuperate power during times when there's excess engine power available and during braking, but the car isn't brake-by wire.
