Where the previous RS5 used a free-revving, naturally-aspirated V8 the new one adopts an RS-specific evolution of Audi’s latest downsized, turbocharged V6. This 2.9-litre engine has two turbos, the massive 599Nm (442lb ft) of torque answering a major criticism of the characterful but breathless V8. Also new is the eight-speed automatic gearbox, its response and that of the steering, suspension and other systems configurable via Audi Drive Select. The engine delivers huge punch, the Quattro system putting it to the road whatever the weather. And this is a seriously, seriously rapid car. But compared with rivals from Mercedes-AMG and BMW M it’s a little soulless and aloof, the light steering and one-dimensional power delivery making it more point-and-squirt projectile than truly inspirational drive.
