Their class-leading performance is guaranteed by the powerful, aluminum, 2.9-litre V6 Bi-turbo engine capable of unleashing 510hp and 600Nm torque at 2,500rpm. Delivery to the wheels is the responsibility of the Alfa™ Active Torque Vectoring system, assisted in the Stelvio Quadrifoglio by the innovative Q4 all-wheel-drive system.
The Quadrifoglio models feature an 8-speed ZF automatic transmission, calibrated to optimise fluidity and comfort so the vehicles can easily be driven on all terrains. The transmission also features a lock-up clutch to give the driver a powerful feeling of in-gear acceleration once the gear is engaged.
Depending on the mode chosen with the AlfaTM DNA Pro, the automatic transmission optimises the ride and handling in all contexts of use. The Giulia and Stelvio Quadrifoglio models are also incredibly efficient in terms of emission and fuel consumption, thanks to the electronically controlled cylinder deactivation system and the “sailing” function, available in Advanced Efficiency driving mode. In RACE mode the cars express their full potential with lightning-fast gear changes in only 150 milliseconds.
The Stelvio Quadrifoglio can accelerate from zero to 62mph in just 3.8 seconds, going on to a top speed of 176mph, while the Giulia Quadrifoglio reaches 62mph in just 3.9 seconds and goes on to 190mph.
