Ferrari Superamerica:

Italian automaker Ferrari unveiled its limited-edition, Pininfarina-designed Superamerica. This sleek, two-seat supercar is the first production car with a tint-adjustable, electrochromic glass roof that’s one piece and doesn’t fold when it goes down. Instead, the glass roof flips rearward and then nests into a shallow storage area behind the seats where it serves as a wind deflector The completely power-operated process takes just 10 seconds.

With a top speed of 200 mph, the Superamerica also is the fastest production convertible in the world. The 540-horsepower 12-cylinder engine generates 434 lb-ft of torque and is mated to a 6-speed F1/manual gearbox. The basis of the Superamerica is the Ferrari 575M Maranello, and there will only be 559 Superamericas built, with availability starting in calendar 2005. Price is $305,000.

Range Rover Sport:

Land Rover unveiled an all-new model in Detroit, adding a fourth vehicle to its US lineup.

Land Rovers have a reputation for its off-road capability, but this new Range Rover Sport adds impressive performance for the street. The most powerful Land Rover ever, the new Range Rover Sport has a 4.2-litre supercharged V8 engine producing a whopping 390 horsepower. Power is sent to all four wheels via a six-speed automatic gearbox.

In addition to the supercharged V8, the Range Rover Sport will also be available with a 300-horsepower 4.4-litre V8.

Matthew Taylor, managing director of Land Rover, said the Range Rover Sport is “ideal for fast, comfortable, long distance driving and practical enough for everyday use. Yet it is also exceptional off-road, offering better all-terrain ability than any competitor.”
