Lamborghini has cracked the top off the Murciélago LP 650-4 to create a roadster version.

Only 50 of this car will be built, Lamborghini says. It gets a 6.5-liter V12 rated at 650 hp--an increase of 10 hp over the LP 640 coupe--and all-wheel drive. Torque is rated at 487 lb-ft.

The LP 650-4 reaches 62 mph in a blistering 3.4 seconds and maxes out at 205 mph.

The sleek grey body is accented by orange styling touches, including the brake calipers. The engine cover is see-through.

Inside, the cockpit has an asymmetric dash and leather appointments.
