Saleen S7 $395,000The S7 power plant is decidedly less outlandish than its ground effects. The motor is derived from a Ford Mustang, then deeply modified. It's made entirely of aluminum, has stainless-steel valves with titanium retainers, and a high vacuum dry sump and stainless-steel exhaust. It breathes through roof-mounted intakes and is mated to a six-speed manual transmission. Power output is a claimed 550 horsepower, with performance of less than four seconds to 60 mph and a top speed in excess of 200 mph. According to the Saleen S7 press release, its aerodynamic ground effects are so effective, and create so much down force (what holds a car to the road at high speeds), that even if you drove the S7 upside down at 160 mph on some sort of Hot Wheels roller-coaster track that exploded into real-life scale, the car wouldn't lose its contact with the road.
