The Alfa Romeo Stelvio is a front engine, all wheel drive, five door, compact luxury crossover SUV manufactured and marketed by the Alfa Romeo subdivision of FCA since debuting at the 2016 Los Angeles Auto Show and entering production at the Cassino Plant at the end of 2016. It is current top Alfa sales with about 43,000 samples per year. Sharing the platform of the mid-size Giulia sedan, the Stelvio uses FCA's Giorgio platform, ultimately to be shared with Maserati, Dodge and Jeep. The name Stelvio derives from the Stelvio Pass, Italy's highest mountain pass, noted for its 48 circuitous switchbacks. Preceded by 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, available in both rear and all-wheel drive configurations. Alfa Romeo made its first off roader, the Matta, in the 1950s. The sporting trim level 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 will offer a 2.9 litre twin-turbo V6 rated with 375 kW (503 hp) developed by Ferrari for Alfa Romeo. 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. For the model year 2019, diesel engines of the Stelvio got updates to meet the Euro 6d emission standards, with AdBlue technology introduced to tackle particulates in the exhaust. 110 kW (148 hp) and 132 kW (178 hp) versions got 7 kW (10 hp) more power. Also, in the United Kingdom, all models have now an 8.8-inch infotainment system with Apple Car Play and Android Auto as standard, and small tweaks have been made throughout the ranges. In Europe, consumption standards now use the WLTP measuring system, which should give more accurate consumption and emission figures. For 2019 Model year Alfa introduced new trim level for Europe the Ti (Turismo Internazionale), this is slightly different than Ti version already for sale in United States, the Ti has 2.0 Turbo Petrol engine, paired with an eight speed automatic transmission, and Q4 all wheel drive. The Stelvio uses the same Giorgio platform already used by the Giulia, but slightly modified and raised by 22 cm (8.7 in) compared to the sedan. The Stelvio has also the same engines and most of the mechanics, including a carbon fiber driveshaft. In addition, compared to the Giulia, its track 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 between the two axles, and a drag coefficient of 0.32 (Cd). To help keep the Stelvio's weight in check, Alfa Romeo uses aluminum for many body parts such as the fenders, hood, and tailgate, as well as for mechanical parts such as the suspension, braking system, 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. Alfa's "Q4" all-wheel drive system, which is normally rear drive but sends up to 50% of power to the front in low grip conditions, is standard on all trim levels, except an entry level turbo petrol version. The Stelvio weighs 1,660 kg (3,660 lb) with fluids, 145 kg (320 lb) less than an equivalent BMW X3 and 110 kg (243 lb) less than a four cyl Porsche Macan.
