McLaren Unveils Sleek Hybrid Supercar at Geneva

Hybrids aren't just for fuel economy any more.

McLaren on Tuesday unveiled a sleek hybrid supercar at the Geneva Motor Show. Sculpted from carbon fiber, in a glittery racing yellow set off by hash-marked slate gray, the McLaren P1 cuts a racetrack figure while boasting superior — for its class — emissions under 200 grams per kilometer. That compares with over 300 grams/kilometer for a super car without hybrid.

P1 program director Paul McKenzie says the hybrid technology has performance advantages because the electric engine fills in the gap before the turbo engine kicks in. It's a tiny effect, but everything counts in supercars.

The P1 can do 0-180 mph (0-300 kph) in under 17 seconds. It sells for $1.3 million, with just 375 in the series.
