The 2021 Stelvio is offered in six trim levels; base, Sport, Ti, Ti Lusso, Ti Sport and Quadrifoglio. Powering most Stelvio trims is a 2.0L direct injection turbocharged 4-cylinder, making 280 horsepower and an exceptional 306 lb-ft of torque. All that torque makes the Stelvio feel spry, even at low RPMs, and can accelerate 0-60 in just 5.4 seconds. Power from that engine is sent to the wheels via an 8-speed automatic transmission. The Quadrifoglio high-performance trim gets a 505-horsepower 2.9L twin-turbo V6. The Quadrifoglio is exceptionally quick, and not just for an SUV, with a 0-60 in an incredible 3.6 seconds. The base and Sport trims are available in rear-wheel drive or all-wheel drive, while the higher trims come standard with all-wheel drive. The base trim comes well-equipped with leather seats, a backup camera, keyless go, passive entry and a remote starting system. Other standard items on the Stelvio include 6-way power driver and passenger seats, an 8-speaker sound system with a 8.8-inch touch screen, Bluetooth connectivity, Apple CarPlay and Android Auto, a 7-inch full color display gauge cluster, a leather-wrapped steering wheel, rain sensing wipers, bi-xenon headlamps, LED tail lamps, power liftgate and 18-inch aluminum wheels. The Stelvio Sport AWD adds a couple of thousand dollars to the base price. In addition to the base model, the Sport comes with aluminum paddle shifters, 19-inch wheels, as well as various black exterior accents around the windows and roof rails. The Stelvio Ti comes with upgraded interior accoutrements than the Sport AWD, though it is a modest increase to the price. The Ti features dark grey oak interior trimming, heated front seats and a heated steering wheel. The top of the line Ti Sport AWD combines the best of all worlds, with the exterior black accents from the Sport combined with the and heated seats. It also gets nicer 20-inch aluminum wheels and sportier front seats. The optional TI performance package adds a locking limited-slip differential and adjustable adaptive suspension. The Quadrifoglio trim transforms the Stelvio into a high-performance sport SUV. Its 505-horsepower engine, massive Brembo brakes and 20-inch wheels highlight the performance. In addition, standard features include a Harmon Kardon audio system, navigation system, blind-spot monitoring, automatic high beams, lane departure warning and forward collision warning.
