The Stelvio Quadrifoglio is set to become the benchmark for the premium SUV segment. The Stelvio expresses the authentic Alfa Romeo spirit, embodying the five ingredients that make Alfa Romeo one of the world’s most desirable automotive brands: distinctive Italian styling, state-of-the-art engines, impeccable weight distribution, unique technical solutions, and an outstanding power-to-weight ratio.

A unique heritage in its name

The Stelvio Pass is the highest mountain pass in Italy, and the 20 km road that crosses it boasts over 75 hairpin bends, stunning views and a quick rise in altitude up to 2,758 metres. Over the years, champions of cycling and motorsport have competed here, making the Stelvio Pass a fully fledged sporting legend and a major tourist attraction. There is only one SUV capable of offering an unrivalled combination of driving pleasure, Italian styling and versatility born from this legacy—and that is the Alfa Romeo Stelvio Quadrifoglio.

A truly Italian ensemble—the striking exterior

The Alfa Romeo Stelvio is a perfect blend of heritage, speed and beauty. To achieve this mix requires a talent for combining the three special ingredients of Italian design: proportion, simplicity and top-quality surfacing. These ingredients spawned the Giulia, and have been comprehensively reworked to adapt them to the Stelvio.

The Stelvio Quadrifoglio’s proportions express strength, dynamism and compactness. Its outline suggests a compact car, starting at the front and developing towards the rear, and a cabin that ends on a steeply raked rear hatch, topped with a spoiler for maximum aerodynamic performance.

The Quadrifoglio version unveiled in Singapore features a body-coloured side-skirt with a carbon insert that further accentuates the car’s sporting character. These features, combined with the front and rear bumpers and striking wheel-arches, make the Stelvio Quadrifoglio more like a sports saloon than a traditional SUV. The Stelvio’s front-end embodies power and aggression, thanks to the air vents for the intercoolers and the classic apertures around the shield-shaped grille, combined with ”sinewy” surfacing.

The back-end of the Stelvio is instantly eye-catching too, due to the sporting appearance it gets from its lower portion, characterised by the four exhaust tips, and from the “Kamm tail” styling that gives the car a unique character.

The simplicity behind Alfa Romeo’s design is the result of a complex creative process that underscores the shapely elegance and tasteful sophistication of Italian-made products. This approach permeates the entire history of Alfa Romeo design, which has always expressed itself through clean, taut lines, and a few select features. The iconic four-leaf clove —the Quadrifoglio Verde—is a symbol of Alfa Romeo’s legendary racing heritage.

Modern aesthetics brought alive by a touch of class—the interior

The same sporting inspiration makes another appearance in the Quadrifoglio’s clean and uncluttered interior. The driver’s seating position is central—a concept underlined by the cabin’s diagonal tunnel, the slightly undulating dashboard, and the small, direct-ratio, leather-wrapped flat-bottom steering wheel that adapts to different driving styles. The ample-sized surfaces and the clear edges of the console wrap around the driver for a sense of control.

The Stelvio Quadrifoglio’s roomy cabin is tailored like a bespoke suit—luxurious and stylish. Finer details can be found on the interior leather trims and sport seats, painstakingly crafted with the selective use of premium materials. Leather, full-grain, real woods and modern fabrics are carefully chosen for their visual and tactile appeal to give a palpable sense of human artistry.

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

State-of-the-art, innovative engines are the hallmark of Alfa Romeos. At the heart of the Stelvio Quadrifoglio is a unique power plant combining technology and performance: a 510 HP 2.9-litre V6 BiTurbo petrol engine 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.

Despite its phenomenal torque and horsepower, the 510 HP 2.9-litre BiTurbo engine is incredibly efficient with fuel consumption, thanks to its electronically-controlled cylinder deactivation system. Like all Alfa Romeo’s next-generation engines, the Stelvio Quadrifoglio’s 2.9-litre V6 BiTurbo petrol unit will deliver the distinctive Alfa Romeo engine note to complement its performance. The 8-speed ZF automatic transmission is specially calibrated to make gear changes in just 150 milliseconds in Race mode. The transmission features a lock-up clutch to give the driver a powerful feeling of in-gear acceleration once the gear is engaged. The auto box optimises fluidity, comfort and ease of driving in all environments, and further improves fuel consumption and CO2 emissions. Steering-column-mounted, aluminium paddle shifters also come as standard.

Innovative and exclusive technical solutions

In keeping with Alfa Romeo’s technical traditions, electronic assistance must never intrude, but instead facilitate the exhilarating driving experience. The Stelvio Quadrifoglio unveiled in the Alfa Romeo Motorshow 2019 confirms this philosophy, because it is structurally unique and engaging. Yet the SUV offers numerous sophisticated systems to make the driving experience even more exciting.

Alfa™ DNA Pro

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

All-wheel drive with Q4 technology

The Stelvio Quadrifoglio’s innovative all-wheel drive system with Q4 technology is designed to manage drive distribution in real time and to deliver top-notch performance, efficiency and safety. The Q4 system’s 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 and lightweight set-up. The transfer case uses advanced active clutch technology to deliver a dynamic ride combined with good fuel economy. The Next-Gen integrated actuator delivers high response speed and precise torque distribution in every Alfa DNA Pro drive mode setting.

The Q4 system continuously monitors numerous parameters to optimise torque distribution between the two axles. 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 behaves 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 over-slip (up to 2.5%) between the two axles, which translates into class-leading control in terms of traction and directional stability when cornering.

Alfa™ Torque Vectoring

Combining Alfa Romeo’s Q4 all-wheel drive with Torque Vectoring technology optimises the Stelvio Quadrifoglio’s drive distribution and accentuates its sporting character. The two clutches in the rear differential controls torque delivery to each wheel separately, and transfers power to the ground more effectively, even when you push the car to its dynamic limits. The result is a car that is fun and safe to drive at all times, without recourse to intrusive inputs from the stability control system.

Suspension system with exclusive AlfaLink™ technology

Up front, the Stelvio Quadrifoglio has a double wishbone system with semi-virtual steering axis to optimise bump filtration, and to ensure quick, precise responses to steering inputs. This exclusive Alfa Romeo set-up affords outstanding levels of lateral grip by keeping the contact patch of the tyre constant when cornering. Regardless of speed and conditions, the Alfa Romeo Stelvio always delivers a natural and instinctive drive.

The rear suspension uses a patented four-and-a-half link system to deliver a winning combination of performance, driving pleasure and comfort. An electronically controlled damping system adapts to driving conditions constantly, giving you control over performance-based or comfort-oriented handling.

Integrated Brake System (IBS)

Having made its debut on the Giulia, Alfa Romeo’s unique Integrated Brake System (IBS) is deployed in the Stelvio Quadrifoglio. This innovative electromechanical system combines stability control with a traditional servo brake to guarantee instantaneous brake response and short stopping distances, while significantly contributing to weight optimisation.

Alfa™ Chassis Domain Control

The Alfa™ Chassis Domain Control (CDC) system is the “brain” of the Stelvio Quadrifoglio, and coordinates all the car’s electronic systems. CDC manages the new Alfa™ DNA Pro selector, the Q4 all-wheel drive, the Alfa™ Torque Vectoring system, the active suspension and the ESC – optimising performance and driving pleasure. The CDC shapes the chassis geometry in real time, dynamically adjusting the mapping of the Alfa™ DNA Pro modes based on the acceleration and rotation data detected by the sensors. Critical situations are prevented and managed by informing the specific control units in advance.

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

One of the primary objectives during the development and design of the Stelvio Quadrifoglio was achieving maximum driving pleasure. The key contributors to this are the perfect weight distribution between the two axles and an optimum power-to-weight ratio. The first of these required astute management of weights and materials, which was achieved by tweaking the layout of the Quadrifoglio and locating the heaviest components as centrally as possible.

The ideal power-to-weight ratio was achieved by using ultra-lightweight materials. Carbon fiber was chosen for the driveshaft to attain better weight balance and minimise the car’s overall weight. The engine, suspension components, brakes, front and rear vehicle frames, doors, wheelarches, bonnet and liftgate all sport aluminium construction.

Despite its reduced weight, the Stelvio Quadrifoglio’s excellent torsional rigidity is not affected. The result of this exquisite design is durability, low noise levels and first-class handling even under extreme conditions.
