In answer to the question above, it's a Porshe... *sigh* .. I drove one once...*double-sigh*... although last time I checked, they only had 2 doors...lol..(SOME INFO FOR YOU )...There are guided missiles with less impressive performance credentials than those engineered into Porsche's Carrera GT. Thanks to a body structure molded in carbon-fiber-reinforced composites and other exotic weight-saving gestures, it weighs but 3,137 pounds, full of fuel. It's loaded with a race-bred 5.7-liter DOHC V-10 engine equipped with four valves per cylinder, variable intake valve timing, dual control computers, a dry-sump lubrication system, and forged titanium connecting rods; output peaks with 605 horsepower at 8,000 rpm but another 400 revs are there for the taking. A 6.6-inch-diameter multi-plate carbon fiber clutch dispatches power to a transversely oriented 6-speed gearbox. Special Flexball shift actuators use a flat steel band guided by ball bearings to connect the driver's palm to each gear. Center-lock magnesium wheels are supported by a mix of forged aluminum and airfoil-section stainless steel control arms. Michelin Pilot Sport 2 radials strive to maintain a grip with terra firma. My test laps at Adria wiped any doubt from my mind that Porsche's $440,000 flagship is the ultimate expression of automotive engineering, the ultimate street-legal racecar, and the ultimate art object for those partial to German sculpture.. such a beautiful car... beautiful memories.. thanks, Tony... aloha .-)
