Audi RS6 may produce more than 600 HP

At one time Japanese regulations prohibited engines in that country producing more than 274hp, and oddly enough a wide array of different engines were all rated at that same level. Given the actual performance of the cars, it was clear that many manufacturers were sandbagging. Audi appears set to do the same with its uber-powerful RS6. The twin-turbo V10 is expected to carry an official rating of 571 hp, but the actual output could be as high as 610hp. Does anyone actually need this much power in a sedan or wagon? Of course not, but sign us up anyway.

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 Lamborghini Gallardo LP560-4

In the world's fastest cars, we've already had two entries, the Lamborghini Murciélago LP640 and the Lamborghini Reventón.
But the Lamborghini Gallardo LP560-4 deserves honorable mention.
This Lambo is powered by a 5.2L V10 (based on the Audi RS6 V10) with FSI direct injection, generating 560 horsepower and 398 ft·lbs of torque.
This allows the LP560-4 to run the quarter mile in 11.2 seconds at 130 mph.

But wait, the Murcielago LP640 can go 0 to 60 in 3.5 seconds, and the LP560-4 can manage 0-60 in 3.3 seconds.......
So is the LP560-4 really faster by .2 seconds?
And the LP640 has a quarter mile time of 11.8 seconds at 126 mph.....
I think I have to change my original post.
It appears the LP560-4 IS faster!

And what does the Lamborghini Gallardo cost?
Around $180,000 to $210,000.
