The Alfa Romeo Stelvio (Tipo 949) is a compact luxury crossover SUV manufactured and marketed by the Alfa Romeo subdivision of FCA, first revealed at the 2016 Los Angeles Auto Show, and entering production at the Cassino Plant at the end of 2016. It is currently Alfa Romeo's best-selling model, with roughly 43,000 sold in 2018.
The Stelvio uses FCA's Giorgio platform, shared with the mid-size Giulia sedan. The name Stelvio derives from the Stelvio Pass, Italy's highest mountain pass, noted for its 48 circuitous switchbacks.
Preceded by Alfa Romeo's first off roader, the Matta, in the 1950s[6] and the Kamal concept car in March 2003, the Stelvio is Alfa Romeo's first production SUV, using a modified version of the Giorgio platform, shared with the Giulia, and available in both rear and all-wheel drive configurations.
The high-performance trim of the Stelvio, the Quadrifoglio, was unveiled on 16 November 2016 at the Los Angeles Auto Show. The European versions of the Stelvio were presented at the Geneva Motor Show in March 2017. The car's engine lineup is similar to that of the Giulia's, with a turbocharged 2.0 litre inline-four and a 2.2 litre diesel inline four.
The Quadrifoglio trim level offers a 2.9 litre F154 twin-turbo V6 rated at 510 PS (375 kW; 503 hp), developed for Alfa Romeo by Ferrari. On January 18, 2017, Alfa Romeo began accepting orders for the Stelvio First Edition in the EMEA region. On November 2, 2017, the Stelvio Quadrifoglio went on sale in Italy.
The Stelvio uses the same Giorgio platform already used by the Giulia, but slightly modified and raised by 22 cm (8.7 in). The Stelvio has also the same engines and most of the mechanics, including a carbon fiber driveshaft. In addition, its track width has increased by 2.9 cm (1.1 in) in the rear and 5.4 cm (2.1 in) in the front. It has a boot capacity of 525 l (18.5 cu ft).
It has a 50/50 weight distribution and a drag coefficient of 0.32 (Cd). To help keep the Stelvio's weight in check, Alfa Romeo uses aluminum for body parts, such as the fenders, hood, and tailgate, as well as for mechanical parts such as the suspension, brakes, and engine.
The suspension, called AlfaLink, implements double wishbones in the front, and an aluminum multi-link configuration in the rear. The springs are longer than those in the Giulia, but stiffer to account for the extra weight and ride height. The driver sits 190 mm (7.5 in) higher from the road than in the Giulia.
Rear-wheel drive as standard, the Stelvio can be optioned with Alfa Romeo "Q4" all wheel drive system, which can send up to 50% of power to the front in low-grip conditions. The Stelvio weighs 1,660 kg (3,660 lb) with all fluids, 145 kg (320 lb) less than an equivalent BMW X3 and 110 kg (243 lb) less than a four cylinder Porsche Macan
