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.

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.
