Audi has released U.S. pricing information for their 2013 S and RS lineup.
The S6 will retail for $71,900 and features a twin-turbo 4.0-liter V8 engine with 420 PS (309 kW / 414 hp) and 550 Nm (406 lb-ft) of torque. It enables the model to accelerate from 0-100 km/h in 4.8 seconds and hit an electronically-limited top speed of 250 km/h (155 mph).
The S7 uses the same engine, but costs $78,800 and is a tenth of a second slower to 100 km/h.
If you want something larger, the $110,000 S8 should fit the bill nicely. It has a twin-turbo 4.0-liter V8 engine that develops 520 PS (382 kW / 513 hp) and 650 Nm (479 lb-ft) of torque. Thanks to an eight-speed transmission and quattro all-wheel drive, the sedan rockets from 0-100 km/h in just 4.2 seconds.
Last but not least, the RS5 coupe will sticker for $68,900 and is powered by a 4.2-liter V8 engine that churns out 450 PS (331 kW / 444 hp) and 430 Nm (317 lb-ft) of torque. It enables the model to run from 0-100 km/h in 4.6 seconds, before hitting an electronically-limited top speed of 250 km/h (155 mph).
The RS5 is currently on sale, while the S6, S7 and S8 will arrive at dealerships this fall.
