This is the Alfa Romeo Stelvio Quadrifoglio, the new model with many class-topping features, which immediately becomes the new benchmark in the premium compact SUV segment. With its awe-inspiring design, performance and technology, Stelvio Quadrifoglio is the “fastest SUV around the circuit”, having clocked the new record for its class on the iconic Nürburgring: 7 minutes 51.7 seconds. Alfa Romeo Stelvio Quadrifoglio is equipped with the exclusive aluminium 2.9 V6 Bi-Turbo petrol engine, developed with inputs from Ferrari technologies and engineering know-how, which delivers maximum power of 510 HP at 6,500 rpm and generates a maximum torque of 600 Nm from 2,500 to 5,000 rpm. This power plant is teamed with the specifically calibrated eight-speed automatic transmission that allows gear shifts in just 150 milliseconds in Race driving mode. Moreover, to maximise the driving experience, the model is equipped as standard with one-piece aluminium paddle shifters integral with the steering column.
Its performance is outstanding: acceleration from 0 to 100 km/h in just 3.8 seconds and best-in-class top speed of 283 km/h. But the Alfa Romeo sports SUV is also incredibly efficient in terms of emission and fuel consumption, thanks to its electronically controlled cylinder deactivation system and the “sailing” function, available in Advanced Efficiency driving mode. For the first time, the 510 HP 2.9 V6 Bi-Turbo petrol engine is combined with the innovative Q4 all-wheel drive system, with its guarantees of unbeatable performance, traction, driving pleasure and safety in all situations. What’s more, Stelvio Quadrifoglio is equipped with the exclusive AlfaTM Chassis Domain Control unit and is the only SUV in its class to provide differential AlfaTM Active Torque Vectoring as standard. Also standard equipment is the innovative AlfaTM Active Suspension, the system that continually, actively controls the suspensions and shock absorbers. Not to mention that Alfa Romeo Stelvio Quadrifoglio guarantees impeccable handing and comfort thanks to its suspension layout, with the exclusive AlfaLinkTM technology: up front it has a double wishbone system with semi-virtual steering axis, with a four-and-a-half link Multilink system at the rear. In any situation and at all speeds, driving the Quadrifoglio SUV, with the most direct steering ratio on the market (12.1:1), is natural and instinctive.
Stelvio Quadrifoglio holds two best-in-class titles which make it the highest-performing SUV in its segment: with a kerb weight of 1,830 kg, the model boasts the best weight/power ratio in its category (3.6 kg/HP) and the best specific power (176 HP/l). These amazing results, synonymous with great pleasure at the wheel, were achieved through perfect weight distribution between the two axles and the use of ultra-lightweight materials such as carbon fibre for the driveshaft and aluminium for the engine, suspensions, brakes, doors, wheel-arches, bonnet and tailgate. Another special feature of Stelvio Quadrifoglio is the innovative electromechanical Integrated Brake System (IBS) – an Alfa Romeo brand exclusive, which first appeared on the Giulia – which has become the new benchmark in terms of both swift response and stopping distance, on any road surface, and weight reduction compared to a conventional braking system. High-performance carbon-ceramic discs will also be available as an optional after the launch.
For the first time, the 510 HP 2.9 V6 Bi-Turbo petrol engine is combined with the innovative Q4 all-wheel drive system, with its guarantees of unbeatable performance, traction, driving pleasure and safety in all situations. In normal conditions, the Q4 system transfers 100% of the torque to the rear axle. As the wheels approach their grip limit, the system transmits up to 50% of the torque to the front axle in real time, by means of an active transfer case. In particular, the Q4 system architecture includes an active transfer case and front differential designed to meet the specific technical requirements of Alfa Romeo, entailing the rapid-response management of high torque levels, with a compact, lightweight set-up. The active transfer case makes use of advanced active clutch technology to deliver an outstandingly dynamic ride combined with good fuel economy. The Next-Gen integrated actuator delivers high response speed and precise torque distribution, in line with the selected Alfa DNA Pro drive mode setting.
Up front, the Stelvio Quadrifoglio has a double wishbone system with semi-virtual steering axis, to optimise bump filtration and ensure quick, precise responses to steering inputs. By keeping the contact patch of the tyre constant when cornering, this exclusive Alfa Romeo set-up affords outstanding levels of lateral grip. The rear suspension uses a four-and-a-half link Multilink system – patented by Alfa Romeo – to deliver a winning combination of performance, driving pleasure and comfort. An electronically controlled damping system, furthermore, adapts to driving conditions instant by instant, enabling drivers to opt for more performance-biased or comfort-oriented handling. Alfa Active Suspension is a system which continually, actively controls the suspensions and shock absorbers to reduce movement of the body of the car in all driving conditions. It constantly interacts with the CDC and Alfa DNA Pro and “calibrates” its actions to suit the driving mode selected, delivering unrivalled comfort and handling.
