Audi has just published pricing for its 2013 model lineup, including the driver-centric S and RS models. From what we can tell, Audi is serious about expanding its share of the luxury market by upping the driver-entertainment value of models throughout its portfolio.

Starting at the high end of the model range, Audi is introducing its S8 sport sedan to the U.S. market for the 2013 model year. Powered by a 4.0-liter twin-turbo V-8, the S8 produces 520 horsepower that’s sent to its quattro drivetrain via an eight-speed Tiptronic transmission.

The combination is good enough to get the S8 from 0-60 in just 3.9 seconds, and pricing starts at $110,895 including destination charge.

Also new for 2013 is the Audi S7 four-door sport coupe. The S7 also gets a twin-turbo 4.0-liter V-8, but output is reduced to 420 horsepower and shifting is handled through a seven-speed, dual-clutch S tronic gearbox. As with the S8, all S7 models come with quattro all-wheel drive, and pricing starts at $79,695.

An all new Audi S6 sedan returns after a one year absence from the U.S. market. It will come packing the same twin-turbo V-8 used in the S7, with the same 420 horsepower delivered through a seven-speed S tronic transmission to all four wheels. Look for 2013 S6 pricing to start at $72,795.

In 2013, Audi is upgrading S5 coupe models to the same supercharged 3.0-liter V-6 used in the S5 convertible. Expect it to produce around 333 horsepower and 325 pound feet of torque, shifted through the buyer’s choice of S tronic or six-speed manual transmission (on coupe models; all convertibles get the S tronic).

As with other S models, quattro AWD is standard on the S5. The 2013 S5 Coupe starts at $51,795 for the six-speed manual and $53,195 for the S tronic. The convertible is priced from $60,195.

Finally, Audi’s S4 soldiers on for the 2013 model year, packing the same supercharged 3.0-liter V-6 found in the S5. Look for pricing to start at $48,495 for the six-speed manual and $49,895 for the seven-speed S tronic.
