Upcoming crossover will be critical to the brand's success.

The Alfa Romeo Stelvio is taking shape as spy photographers have snapped new photos of the Italian crossover.

Set to become one of the brand's most important models, the Stelvio is heavily camouflaged but appears to adopt a stylish front fascia that is heavily influenced by the Giulia.  The styling details are hard to make out but we can see a prominent grille that is flanked by slender headlights and large lower air intakes. 

Moving further back, there's a rakish windscreen, a gently sloping roof, and a heavily disguised tailgate.  Other notable highlights include a dual exhaust system and wraparound taillights.

Alfa Romeo hasn't said much about the model but it is expected to ride on the same platform that underpins the Giulia. Rear-wheel drive will likely be standard but all-wheel drive will also be available.

Engine options are expected to carryover from the Giulia so the U.S. spec model should be offered with a turbocharged 2.0-liter four-cylinder engine that produces 276 horsepower and 295 pound-feet of torque. There will also be a high-performance Quadrifoglio Verde variant that uses a 2.9-liter biturbo V6 engine that develops 505 hp and 443 lb-ft of torque.  It enables the Giulia Quadrifoglio Verde to accelerate from 0-60 miles per hour in 3.8 seconds before hitting a top speed of 191 mph.

The Alfa Romeo Stelvio is expected to be unveiled later this year so look for a possible debut at the Los Angeles Auto Show.
