As with the Giulia saloon, the Stelvio Quadrifoglio is powered by the all-aluminium, bi-turbo 2.9-litre V6 petrol with 503bhp and 443lb ft used in the Giulia Quadrifoglio.
Unlike the Giulia, though, the hot Stelvio will be offered only with four-wheel drive, with Alfa Romeo’s Q4 system – which sends 100% of the torque rearwards in normal conditions, but can divide between the front and rear up to 50/50 - coupled with torque vectoring for the first time. The use of two clutches in the rear differential allow torque vectoring between the rear wheels.
