Stelvio Quadrifoglio, the first Quadrifoglio also to be a SUV, goes on sale. The new model from Alfa Romeo has many class-topping features, and 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.
510 HP 2.9 litre V6 Bi-Turbo Petrol Engine
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. What’s more, 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. Stelvio Quadrifoglio can accelerate from 0 to 100 km/h in just 3.8 seconds, with a best-in-class top speed of 283 km/h.
Innovative Q4 all-wheel drive system combined with AlfaTM Active Torque Vectoring on the new SUV Alfa Romeo Stelvio Quadrifoglio
For the first time, the 510 HP 2.9 V6 Bi-Turbo petrol engine is combined with the innovative Q4 all-wheel drive, 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 a transfer case. 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. Last but not least, to maximise the driving experience, Stelvio Quadrifoglio is equipped as standard with one-piece aluminium paddle shifters integral with the steering column.
AlfaTM Chassis Domain Control (CDC) and AlfaTM Active Torque Vectoring
Stelvio Quadrifoglio is equipped with the exclusive AlfaTM Chassis Domain Control unit and is the only one to provide differential AlfaTM Active Torque Vectoring as standard. CDC acts as the “brain” of the Stelvio Quadrifoglio, and coordinates all the car’s electronic systems, to deliver the best performance and the utmost driving pleasure at all times. Specifically, the system and simultaneously assigns specific tasks to the various active systems, such as the Alfa™ DNA Pro selector, the Q4 all-wheel drive, the AlfaTM Active Torque Vectoring system, the AlfaTM Active Suspension system and the ESC. The Torque Vectoring technology optimises the Stelvio Quadrifoglio’s drive distribution and accentuates its sporting character. The two electronically controlled clutches in the rear differential make it possible to control torque delivery to each wheel separately. This ensures the optimal transfer of power to the ground even when the car is pushed to its dynamic limits. This makes the Stelvio safe and fun to drive at all times, without recourse to intrusive inputs from the stability control system.
Best-in-class specific power (176 HP/l) and weight/power (3.6 kg/HP)
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, which guarantee superlative driving pleasure, are the outcome of perfect weight distribution between the two axles, which required astute management of weights and materials, achieved by tweaking the Alfa Romeo SUV’s layout and arranging the heavier elements in the most central position possible. The ideal power-to-weight ratio, meanwhile, was delivered with the aid of ultra-lightweight materials such as carbon fibre for the driveshaft and aluminium for the engine, suspensions, brakes, doors, wheel-arches and bonnet. The reduced weight does not affect the car’s excellent torsional rigidity, which guarantees durability, low noise levels and first-class handling even under extreme stresses.
Suspension system with exclusive AlfaLinkTM technology and the category’s most direct steering
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. But regardless of speed and conditions, the Alfa Romeo Stelvio always delivers a natural, instinctive drive. 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 you 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.In any situation and at all speeds, driving the Alfa Romeo Stelvio Quadrifoglio, with the most direct steering ratio on the market (12.1), is natural and instinctive.
Integrated Brake System (IBS) and carbon-ceramic discs
Having made its debut with the Giulia, Alfa Romeo’s unique Integrated Brake System (IBS) is now in use on the Stelvio Quadrifoglio. This innovative electromechanical system combines stability control with a traditional servo brake to deliver instantaneous brake response and hence shorten stopping distances, while also making a significant contribution to weight optimisation. On request, after the launch, Stelvio Quadrifoglio customers will be able to choose carbon ceramic brake discs, assuring both lighter weight (17 kg less than the standard type) and greater mechanical strength, even at the highest temperatures, in both dry and wet conditions.
Unique design defines the Alfa Romeo Stelvio Quadrifoglio
The Alfa Romeo Stelvio Quadrifoglio is the finest expression of Italian design, interpreted with Alfa Romeo’s unique flair. The perfect synergy of form and function, in a sensual, muscular body, made even more extreme by the intrinsic nature of the model’s type. A high-performance SUV where style and design are not merely aesthetic considerations but support crucial factors including aerodynamics, speed, power and handling. This is clearly reflected in the bonnet with has structural vents to allow air to pass from the inside to the outside of the engine compartment, the intercooler air vents at the side, the sporty side-skirt and the massive wheel arches, all body-coloured, not to mention the four exhaust tips and the unmistakable “Kamm tail”, rooted in the Alfa Romeo tradition. What’s more, the Stelvio Quadrifoglio interior has been “tailored” like an exquisite bespoke suit, with painstaking craftsmanship and premium materials: carbon fibre, leather and Alcantara. Stelvio Quadrifoglio is the supreme version of a car which already offered unique, unmistakable proportions, style, elegance and identity. In this configuration, everything is raised to new heights, with even greater impact. The nose, with the iconic, immediately recognisable “Trilobo” motif, and all the other parts specific to this version, inside and in the cockpit, have been designed to form a single whole, incarnating the brand’s deepest values, encapsulated in a simple two-word phrase, almost a mission statement: “Necessary Beauty”.
AlfaTM Connect 3D infotainment system with Apple Car Play and Android Auto.
The centre of the dashboard is dominated by the new 8.8″ Connect infotainment system – with 3D navigation function on request – which incorporates Apple CarPlay and Android AutoTM, the technologies developed by Apple and Google respectively to replicate the smartphone environment on the on-board display, for constantly connected, safe, user-friendly life at the wheel.
