Like the A5 it's based on, the 2026 RS5's dashboard is dominated by a triple-screen setup.

RS5's steering wheel ditches the A5's touch-capacitive controls in favour of proper physical buttons and knobs.

'RS' logos are peppered throughout the RS5's cabin, including the floor mats and logo projectors in the doors.

Gratuitous red ambient lighting and accenting give off a very sporty vibe.

Sports seats up front get honeycomb quilting, electrical adjustment, and heating and massage functions.

Leather upholstery is optionally available for the RS5's cabin, which can be paired with red contrast stitching.

PHEV powertrain eats into boot space, with the RS5 sedan offering 350 litres.

The RS5 Avant's boot, meanwhile, can hold up to 361 litres of luggage.
