Q4 all-wheel drive to manage the car’s drive distribution in real time

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.

The Q4 system continuously monitors numerous parameters to optimise torque distribution between the two axles according to what the car is doing and how much grip there is beneath the wheels. This technology can predict imminent loss of grip by processing the data it receives from the lateral and longitudinal acceleration, steering-wheel angle and yaw sensors. In normal conditions, the Stelvio Quadrifoglio with Q4 system acts like a rear-drive vehicle, with 100% of the torque sent to the rear axle. As the wheels approach their grip limit, the system transfers up to 50% of the torque to the front axle via a dedicated transfer case. To modulate torque distribution with the utmost speed, the system uses a high degree of mechanical overslip between the two axles, which translates into class-leading control in terms of traction and directional stability when cornering.

State-of-the-art technology for impeccable handling and great driving pleasure

In keeping with Alfa Romeo’s technical traditions, electronic assistance must never be intrusive, but merely facilitate the driving experience, which is exhilarating in itself thanks to the passionately and painstakingly designed chassis and suspension system. The Stelvio Quadrifoglio confirms this philosophy: it is structurally unique, but still offers numerous sophisticated systems to make the driving experience – already assured by the car’s underlying technical excellence – even more thrilling.

AlfaTM Chassis Domain Control (CDC) and AlfaTM Active Torque Vectoring

Alfa Romeo 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 Alfa Romeo SUV, and coordinates all the car’s electronic systems, to deliver the best performance and the utmost driving pleasure at all times. Specifically, the AlfaTM Chassis Domain Control system simultaneously manages and assigns specific tasks to the various active systems, such as the AlfaTM Active Torque Vectoring system, the AlfaTM Active Suspension system and the ESC, in accordance with the setting selected by the driver with the AlfaTM DNA Pro selector.

Stelvio Quadrifoglio is the only SUV in its class to provide the AlfaTM Active Torque Vectoring differential as standard. 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.

Alfa DNATM Pro with Race mode

The Alfa Romeo Stelvio Quadrifoglio is also equipped with the new Alfa DNA Pro selector, which modifies the car’s dynamic response according to which mode the driver selects: Dynamic, Natural, Advanced Efficiency (energy-saving mode) and Race (ideal for maximum performance).

In detail, the Dynamic setting modifies the engine control parameters for faster power delivery, increases the gear shift speed and modifies the suspension response for sportier on-road driving. The Natural mode, on the other hand, sets the power delivery and suspensions to ensure comfort and demure handing in everyday driving, while Race mode allows deactivation of the stability and traction controls, enhances the roar of the exhaust and maximises performance for a memorable circuit driving experience in real racing style. Last but not least, the Advanced Efficiency setting improves efficiency and cuts consumption with functions such as “sailing” and cylinder deactivation. The AE mode is also strongly recommended in low-grip situations.

Exclusive AlfaLinkTM suspensions, AlfaTM Active Suspension and the most direct steering in the class

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.

Last but not least, in any situation and at all speeds, driving the Alfa Romeo Stelvio Quadrifoglio, with the most direct steering ratio on the market (12.1:1), 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 also in use on Alfa Romeo 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.

Perfect weight distribution and the ideal power-to-weight ratio

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.

Unique style evolved in the service of performance

The Alfa Romeo Stelvio Quadrifoglio, is the finest expression of Italian design, interpreted with Alfa Romeo’s unique flair, and the perfect synergy of form and function, in a sensual, muscular car body.

The Alfa Romeo Stelvio already has a very strong, distinctive look and this is even more the case in the Stelvio Quadrifoglio, with solutions chosen to create an even sportier style and cater for the car’s specific technical features.

The front end of the Stelvio Quadrifoglio is a perfect mix of seduction and emphatic proportions, conveying a strong message of aggression and power. The grille is original in style, with the familiar slots around the shield-shaped grille, together with “sinewy” surfacing and the “trilobo” motif with intercooler air vents at the side. The iconic, immediately recognisable “Trilobo” motif, and all the other parts specific to this version, 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”.

The side view is sensual and athletic, with the exquisite touch of the famous “quadrifoglio” four-leaf clover on the wheel arch. The overall dimensions are not particularly large: 470 cm long, 168 cm high and 216 cm wide, with its compact proportions expressing dynamism and strength. This sensation is emphasised by the wheel arch and the widespread use of the body colour, heightening the impression of a car firmly anchored to the terrain. The exhaust tips also give the impression of reaching out to the large-sized wheels – 20″ in burnished alloy, with different tyres at the front and rear (an exclusive for this class) – and lead the eyes towards the road. So the volumes in the car’s visual make-up were chosen partly in response to structural needs, and its style and design are not merely aesthetic considerations but support crucial factors including aerodynamics, speed, power and handling. This is also reflected in the bonnet with structural vents to allow air to escape from the engine compartment, the sporty side-skirt and the massive wheel arches, all body-coloured, and the four hot exhaust tips.

The Alfa Romeo Stelvio Quadrifoglio cockpit is simple and tasteful, forged around the driver. The controls are grouped together on the steering wheel, which is small and direct to suit all driving styles. The diagonal tunnel and slightly undulating dashboard converge on the driving seat, “tailored” like a bespoke suit, with painstaking craftsmanship and with lavish use of carbon fibre on the console, tunnel, dashboard trim, handle inserts and steering wheel rim. The black seats, in leather and Alcantara, are specific to the model and are more strongly shaped for more support when cornering. There is a choice of red, white and green and dark grey seams. The contrasting materials (leather, alcantara and carbon fibre) and coloured stitching combine technology with fine workmanship and attention to details, for an interior with lashings of personality. The dark pillars and roof lining also contribute to Stelvio Quadrifoglio’s character.

Alfa Connect 3D infotainment with Apple CarPlay integration and Android Auto compatibility

Alfa Romeo Stelvio Quadrifoglio also introduces major novelties in terms of infotainment: the fastest SUV in its class is the first to offer support for Apple CarPlay, the smarter and safer way to use your iPhone in the car.

CarPlay lets the user get directions optimized for traffic conditions, make and receive calls, access text messages, and listen to music, all in a way that allows them to stay focused on the road.

Alfa Romeo Stelvio Quadrifoglio is compatible also with Android AutoTM that brings the Android experience into the car by ‘projecting’ apps and services to the screen in the central display, and is designed to make it safer and easier to get the information needed while driving. Drivers can use Google MapsTM for directions and easily access their favorite music, media and messaging apps in the car. Easy, immediate interaction with devices provides the convenience of maintaining the same operating system even in the car, for safe, simplified constantly connected driving, meaning great quality of life on board and improved ergonomics.

These new technologies, , also extend the capabilities of the innovative Alfa Connect 3D NAV 8,8″ available as standard or on request on Alfa Romeo Stelvio Quadrifoglio, depending on the market. Developed jointly with Magneti Marelli, the infotainment system offers a sophisticated series of features and functions, including a next-generation human-machine interface, with control by means of the Rotary Pad and using the high resolution display integrated in the dashboard design. In addition, thanks to “optical bonding” technology, the user benefits from an excellent level of visualisation and readability on the display.

Finally, as well as controlling the DAB digital radio and the HI-FI digital audio, the Alfa Connect 3D NAV 8,8″ system includes, as standard, navigation functions with high-resolution 3D maps. The system is quick to calculate routes and can be used even if the GPS signal is missing by exploiting Dead Reckoning technology. It also allows updating of TomTom maps via USB, and display of driving style data and the type of ride set by the Alfa DNA selector.
