Under its sinewy clamshell hood sits a 444-hp twin-turbo V-6. That’s six fewer horsepower than the outgoing V-8 model, but torque has increased dramatically from 317 lb-ft to 443. The output routes through Audi’s rear-biased Quattro all-wheel-drive system via a smooth-shifting eight-speed automatic transmission.
Behind the wheel, the meanest version of Audi’s sports coupe is easy to control and enjoyable to exploit, with docile handling that is predictable in both wet and dry conditions. The real beauty is how supremely comfortable the RS5 rides over distances short or long. While rivals such as the BMW M4 and the Mercedes-AMG C63 demand more attention during spirited sessions, the Audi is involving and intoxicating nonetheless.
