Ferrari Challenge Stradale

The Ferrari Challenge Stradale is a variation of the Ferrari 360 Modena.
When the car was created, the designers were thinking 20% track use in mind and 80% road use.
And it shows in the performance.
The Challenge Stradale's 90° F131 V8 engine only puts out about 25 more horses (425) than the Modena, but the car is lighter, giving it a superior power to weight ratio.
It has a 0 to 62 mph time of just 4.1 seconds with a top speed of 183 mph.
(Although the 2008 version is said to pull 0-60 in 3.9 seconds)
The Stradale can pull the quarter mile in about 12.5 seconds at 114.1 mph.

The Audi RS6 5.0 TFSI quattro

The Audi RS6 5.0 TFSI quattro is the land rocket of the Audi A6 models.
It is powered by an all-aluminum alloy 5.0 liter V10 twin-turbocharged Fuel Stratified Injection (FSI) engine.
The V-10 is rated at 580 horsepower, and 479 foot pounds of torque.
The official performance figures for the RS6 Avant are:
0 to 62 mph in 4.1 seconds.
0 to 124 in 13.1 seconds.
It has an electronically governed top speed of 155.3 mph, but you can get a factory option that bumps that figure up to 192.6 mph.
To keep the V-10 cool, the RS6 needs seven radiators, and four electric cooling fans.
Unfortunately, the RS6 Avant will not be available in the U.S., but a sedan was unveiled in August 2008, and will probably be offered in North America.

2003 Mercedes-Benz CL55 AMG

While not quite as powerful as the CL65 AMG, the 2003 Mercedes-Benz CL55 AMG was still a force to be reckoned with.
Motor Trend described it as "Arnold Schwarzenegger in an Armani tuxedo".
Powered by a 493 horsepower, supercharged 5.4 liter single overhead cam V-8, the CL55 could turn the quarter mile in 12.38 seconds at 114.45 mph.
The listed top speed of the CL55 was 155 mph, but that's because of the electronic governor that most German manufacturers (except Porsche) place on their cars.

The CL55 was based on the Mercedes-Benz W215 platform and was produced in limited numbers (around 500 in the US) between 2000 and 2002.

The base price of the CL55 was $114,600.
And the fuel economy was 14 mpg in the city and 22 on the highway.
