The RS4 and RS5 are powered by a 2.9 TFSI V6 twin-turbo engine making the same power as the previous model (B8) while making more torque (extra 170 Nm) from a smaller displacement engine, resulting in better fuel efficiency and acceleration.

The RS4 and RS5 B9 could accelerate from 0 to 100 km/h (62 mph) in 3.9 seconds, and achieve a maximum speed of 280 km/h (174 mph)

RS 4 Avant and RS5 are available with an 8-speed ‘Tiptronic’ automatic transmission, further developments include a new chassis featuring a five-link front and rear suspension coupled to Audi Sport’s Dynamic Ride Control system offering variable damping control. Other options included with a carbon-fibre engine cover and ceramic front brakes.
