Alfa’s 2.9-litre twin-turbo V6, 503bhp SUV


Alfa Romeo is looking at chasing down Porsche Macan sales with this all new SUV. A first fro the Italian car brand, this SUV called the Stelvio, is named after the famous mountain pass in the Italian Alps and is set to get head-to-head with the Jaguar’s F Pace, Porsche’s Macan and Range Rover’s Evoque when it goes on sale next year.


Exhilarating performance from the 510 HP 2.9-litre V6 BiTurbo Petrol Engine


State-of-the-art, innovative engines are another hallmark of a genuine Alfa Romeo. That’s why the Stelvio Quadrifoglio mounts a unique power plant in terms of both technology and performance: a 510 HP 2.9-litre V6 BiTurbo petrol with 8-speed automatic transmission.


Drawing inspiration from Ferrari technologies and technical know-how, the 6-cylinder BiTurbo petrol engine is made entirely of aluminium to reduce the weight of the vehicle, especially over the front axle.


What’s more, despite its phenomenal torque and horsepower, the 510 HP 2.9-litre BiTurbo Petrol is also incredibly efficient in terms of fuel consumption, thanks to its electronically controlled cylinder deactivation system. And like all Alfa Romeo’s next-generation engines, the Stelvio Quadrifoglio’s 2.9-litre V6 BiTurbo petrol unit will, of course, deliver that distinctive Alfa Romeo engine note to complement the performance.


Lastly, the 8-speed ZF automatic transmission is specifically calibrated to make gear changes in just 150 milliseconds in Race mode. 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 you set with the AlfaTM DNA Pro selector, what’s more, the auto box optimises fluidity, comfort and ease of driving in all environments, including around town, and further improves fuel consumption and CO2 emissions. Steering-column-mounted, aluminium paddle shifters also feature as standard.


As well as this 510 HP unit that’s exclusive to the Quadrifoglio guises, Alfa Romeo has confirmed that the other engines in the Stelvio range will include the 280 HP 2.0-litre Turbo petrol with 8-speed automatic transmission. This is an all-aluminium 4-cylinder unit that puts out 280 HP at 5,250 rpm and maximum torque of 400Nm at 2,250 rpm. In addition to the MultiAir electrohydraulic valve actuation system, the distinctive features of this engine include the “2-in-1” turbo system and the 200-bar high-pressure direct injection system, which deliver a particularly quick response to accelerator inputs across the rev range, plus first-class fuel-efficiency.
