The Roadster is very similar to the coupe it is based on, with a few exceptions. The only exterior change -- aside from a retractable canvas roof -- is the addition of cooling vents behind the air intakes. The interior has also been modified somewhat, and the body structure has been reinforced to compensate for the lack of a structural roof.

The latest iteration of the car is called the LP640, and builds on a refresh and power bump from a mid-cycle refresh. It offers 631 horsepower via a 6.5-liter V12, improving performance significantly over the original Murcielago Roadster. The huge motor churns out 487 pound-feet of torque at 6000 rpm.

The Murcielago LP640 can be had with a six-speed manual or six-speed automated manual transmission. Either way, the sprint to 60 mph should take no more than 3.4 seconds. The mid-engine supercar comes standard with all-wheel-drive.It features scissor doors, a rear spoiler that can be raised to an angle of 70 degrees, side air scoops that automatically open at speed, folding side mirrors for increased aerodynamics, and electronic Launch Control.
