2015 Audi S8 plus revealed

Audi is making a strong statement with the new Audi S8 plus with a power output of 445 kW (605 hp) and a top speed of up to 305 km/h (189.5 mph) .
Its body is made almost entirely of aluminum. Its design is based on the Audi Space Frame (ASF) and weighs just 231 kg (509.27 lb) – which is the lightest among the competition.
Audi engineers have further advanced the development of the 4.0 TFSI engine for the new S8 plus. The sonorous V8 biturbo engine now has a power output of 445 kW (605 hp) and a maximum torque of 700 Nm (516.3 lb‑ft); in overboost mode, it can even produce 750 Nm (553.2 lb‑ft). The large sport sedan – whose power was boosted 63 kW (85 hp) compared to the S8 – accelerates from 0 to 100 km/h (62.1 mph) in 3.8 seconds, and its governed top speed of 250 km/h (155.3 mph) can optionally be increased to 305 km/h (189.5 mph).
The increase in top speed to 305 km/h (189.5 mph) is part of the dynamic package, which is a standard feature for the S8 plus in Germany. In addition to carbon-fiber reinforced ceramic brakes with anthracite-gray brake calipers and the Audi ceramic logo, the package also includes a sport exhaust system modified by quattro GmbH. It gives the Audi S8 plus a sporty V8 sound characteristic.
