The 2.9 TFSI V6 bi-turbo engine, which Audi developed from the ground up, offers sharp increases in power and efficiency as well as an incomparably full-bodied RS sound. It delivers 331 kW (450 hp). And it‘s peak torque of 600 Nm (442.5 lb-ft) - 170 Nm (125.4 lb-ft) more than the previous model - is available across a broad engine speed range from 1,900 to 5,000 rpm. The top model in the A5 family sprints from 0 to 100 km/h (62.1 mph) in 3.9 seconds, and reaches a top speed of 250 km/h (155.3 mph) - with the optional RS dynamic package it can even reach 280 km/h (174.0 mph).
In the induction tract, the intake valves close well before the piston reaches bottom dead center. This very short opening time keeps the fresh gas flow comparatively small. When the piston moves back up again after reaching bottom dead center, the compression phase starts later than usual. This allows a high geometric compression ratio of 10.0:1 - the combustion then takes place in a relatively small volume. In comparison to the short compression phase, the expansion phase is extended, which results in a high level of efficiency.
As an alternative to the further-developed electromechanical power steering, Audi also offers dynamic steering with RS-specific tuning. This uses a superposition gear to vary its ratio by up to 100 percent, depending on the car‘s speed and the mode selected in the Audi drive select dynamic handling system. At the cornering limits, the system countersteers with tiny impulses, thus further boosting the dynamism and driving safety. In the dynamic setting within Audi drive select, the superposition of the dynamic steering is stiff in order to support a more sporty driving style.
