1968 Plymouth S/S Barracuda

One of the fastest Muscle cars ever made was the 1968 Plymouth S/S Barracuda with the dual 4-barrel carburetor 426 Hemi.
The Hemi put out 525 horsepower (although it was rumored that it was actually 600+ horses) and turned the quarter in 10.5 seconds at 130 mph.
Now this is stock times.
Imagine what a few modifications would do.
Not that there was a lot of need.
Besides coming equipped with the dual 4-barrel 426 Hemi, it also had Competition Hooker headers, exhaust pipes, and mufflers from the factory.
Of course not a lot of these were made.
And when you ordered one of the beasts, you had to sign a disclaimer indicating that you understood the vehicle was sold without warranty and that it didn't conform to Federal Vehicle Safety Standards.
It came from the factory without a heater, outside mirrors or a right side seat belt.

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.

The Ford GT

The world's 11th fastest production car, the Ford GT was built by the Ford Motor Company from 2003 to 2006.
The Ford GT is powered by an all-aluminum 5.4L Modular V8 powerplant with a Lysholm twin screw-type supercharger.
The engine puts out 550 horsepower and 500 foot-pounds of torque.
This allows the Ford GT to run 0 to 60 in 3.7 seconds and 0-100 in 7.4 seconds.
It also gives the Ford GT an 11.2 second quarter mile time at 131.2 mph.
Because it's electronically limited, the top speed is 212 mph.
And for a 200 mph + car, the fuel economy isnt all that bad, 12 mpg city and 19 mpg highway.
When they were new, they were going for around 120,000 dollars. But since production has stopped, you can probably expect that figure to go up.

The Mosler MT900S

Okay this is not a widely produced car.
As a matter of fact, unless you are George Lucas (he took delivery of the first street legal one in December 2006), you may not have ever heard of it.
The MT900s is built by Mosler Automotive.
It's powered by a Corvette LS6 V8 with an Eaton supercharger, with a maximum boost pressure of 6.0 psi.
This gives the 346 inch engine 600 bhp and 557 foot pounds of torque.
In real time that allows the MT900S to get from 0 to 60 in about 3.1 seconds, 0 to 100 in 6.5 seconds and 0 to 150 in 13.8 seconds.
And it also enables the MT900S to blast through the traps at 135 mph in 11 seconds.
Base price is about $189,000.
Or you can add around $50,000 and opt for the MT900S Photon, which is 220 pounds lighter than the MT900s and has a few extra goodies.
And you know, the MT900 gets 15 mpg in the city and 22 mpg on the highway.
Thats really not too shabby for a 600 horsepower car.
A Lamborghini Murcielago only gets 8 mpg city and 13 highway.

The Saleen S7 Twin Turbo

The limited-production, hand-built, high-performance Saleen S7 Twin Turbo was Saleen's first car not based on an existing design.
It was completely developed digitally using tools such as Unigraphics and Rhinoceros 3D.
It may have been born on a computer, but it came to life on the track.
The heart of the S7 is a 427.6 cu inch all-aluminum OHV V8 engine, upgraded with two Garrett turbochargers producing approximately 6 psi of boost.
This gives the S7 750 horsepower and 700 lb·ft of torque.
What does this translate into on the track?
0-60 mph in 3.2 seconds, 0-100 in 6.2 seconds and 0-200 mph (yes, 0-200) in 27 seconds.
This also allows the S7 to blast through the quarter mile in 10.6 seconds and gives it a top speed of 248 mph.
And get this, in 2006, Saleen offered an optional competition package for the S7 Twin Turbo that put the engine output up to 1000 horsepower!
How much will this land rocket set you back?
Around $585,296.

The World's Fastest Corvette

In a change from all the high dollar exotic cars I usually feature here, this is a high dollar exotic Chevrolet.
The Chevrolet Corvette C6 ZR1 may be the fastest Corvette ever built.
The ZR1 is powered by a modified LS3 (the LS9) that produces 638 hp and 604 ft.lbs.of torque.
This is largely due to the sixth-generation Eaton TVS R2300 roots 4-lobe supercharger with an intercooler that's mated to the LS9.

What does all this mean in a straight line?
Try 0 to 60 in 3.43 seconds with an estimated top speed of 210 mph.
The Vette can blast through the quarter mile in 10.988 seconds, at 135 mph.
The cost on this little number?
About $115,000.
Not bad compared to some of the other cars we've had on here.

The Jaguar 420

The Jaguar 420 was produced, starting in August 1966 by Jaguar.
It was designed to be the ultimate compact sporting saloon (sedan).

Believe it or not, with its twin carburetor 3.8 liter engine, this boxy looking vehicle could do 0 to 60mph in under 10 seconds, and had a top speed of over 125 mph!

The Jaguar 420 ceased production in September 1968.
