For 2013, Audi is introducing a new 4.0T twin-turbo V8 engine into the S6, S7, and S8 models, as well as bringing the RS5 across the pond to the American market.
The most powerful iteration of the new 4.0-liter twin-turbo V8 can be found in the S8, where the engine makes 520 hp, accelerating the car from 0-60 mph in 3.9 seconds. An eight speed automatic transmission is mated to the motor in the S8, while the S6 and S7 are fitted with a seven-speed double clutch S tronic transmission. The same 4.0-liter engine make 420 hp in both the S6 and S7.
Active cylinder deactivation is present on all three cars, helping to offset the fuel usage of the Quattro all-wheel drive setup that is standard on all three vehicles. On the inside, the premium feel is achieved by atlas carbon fiber inlays and diamond-stitched sport seats. For technology, the S line gets Audi’s MMI navigation plus system with Audi connect.
The S6 starts at a base price of $71,900, the S7 will come in at $78,800, and the range-topping S8 will command a $110,000 price tag.
The reintroduction of the RS track focused lineup started with the TT RS, and the next RS model to hit the U.S. is the RS5. Run by a naturally-aspirated 4.2-liter V8 that makes 450 hp, the RS5 sprints to 60 mph in 4.5 seconds. Sport tuned suspension, sport differential with a crown gear, combined with Audi’s Quattro all-wheel drive give the RS5 its performance boost. Style wise, the RS5 sets itself apart with the signature honeycomb Singleframe grille, unique front and rear bumper, front splitter and rear diffuser.
The RS5 will sell for $68,900 when it hits dealers.
The regular S5 is getting a new engine option as well for 2013, a 3.0-liter supercharged V6 that makes 333 horsepower and 325 pound-feet of torque. It will sell for a starting price of $50,900, ranging up to $65,950.
The last of the Audi sports cars, the TT, is also getting some slight upgrades for 2013. New wheels, exterior colors and S line performance package are now available along with a new bi-color leather interior. The TT will start at $41,650, and go all the way up to $57,200 for the TT RS model.
