Audi has announced that the 2007 S6 sedan will start at $72,000 in the U.S., while the 2007 S8 (Euro-spec model shown) will begin at $92,000. Don't forget the $700 destination charge that's not included in the price, as well as the $1,300 gas-guzzler tax for the S6 and $1,700 for the S8. Still, for now these two vehicles stand as the least expensive way to mash the throttle of the Lamborghini Gallardo's V10, which has been detuned to 435 hp in the S6 and 450 hp in the S8. With that kind of motivation, the S6 can charge to 60 mph in 5.1 seconds and the larger S8 can reach the same mark in a more impressive 4.9 seconds. Neither are quite as fast as the Gallardo, which can reach 60 mph in a hair under four seconds, but can the raging baby bull carry four people in comfort? We think not.
