OKay.....that awsome company - Henessesy Motorsports - The company that produced the 1,100 horsepower Viper that does 0-60 in 1.85 seconds and 1/4 in 9.66 without NOS and 8.93 with NOS - Brings us a new kit for the RS6!
Not that it wasn't fast enough, but now you can make it go up to 600 horsepower.

I don't know about you guys, but for a automatic luxery supercar that can do 0-60 in 3.8 seconds is pretty damn good. Just costs a additional 30k
