The engine

4.0 TFSI

Twin-Turbo V8

A muscular, deep-chested twin-turbo V8 that delivers a broad torque plateau and the effortless, savage acceleration that defines the fastest RS wagons.

Audi's 4.0 TFSI was co-developed with Bentley and is shared across VW Group performance and luxury models, from the RS6/RS7 to Bentley's Continental and Bentayga.

The twin-scroll turbos nestle inside the 90-degree V in a 'hot-vee' design for sharper throttle response.
It uses cylinder-on-demand technology that shuts down four cylinders under light load to save fuel.
In Bentley applications the same architecture is tuned for refinement rather than outright aggression.
