Given the variety of shapes and sizes in Audi's portfolio, from the petite A1 to the bulky Q7, you'd think the German automaker already had a vehicle for every niche. There are a few more to be filled, though, such as the compact luxury crossover segment, where the all-new 2012 Audi Q3 will do battle against BMW's recently launched X1. Audi first showcased the future Q3 with its Cross Coupe Quattro concept during the 2007 Shanghai auto show, and its production descendant is coming back to this year's Shanghai show for its reveal.

At 172.8 inches long and 72 inches wide, the Q3 is roughly the same size as Volkswagen's Tiguan, but the Audi is sportier and more coupe-like, with a gently sloping roofline and a steeply raked hatch. The handsome design is essentially a shrunken version of Audi's Q5 and Q7 crossovers. Employing aluminum for the hood and rear hatch helps keep the Q3's curb weight to about 3300 pounds.

A large, black mesh grille adorned with Audi's four-ringed badge defines the nose, which is surrounded by a thin line of chrome trim. The headlights are reminiscent of those on the A4 and A5, and the optional xenon headlamps add a C-shaped collection of LED running lights. Audi calls the body creases just below the car's beltline the "tornado line," which helps define the Q3's flared front fenders.

The Q3 sports a similar tailgate design to the larger Q5 and Q7, with a subtle roof spoiler and wedge-shaped taillight assemblies that include optional LED treatments. The high stance affords 6.7-inches of ground clearance -- not enough for serious off-roading, but plenty for a suburb-bound crossover.

The interior follows typical Audi standards, with a smart assortment of dark plastics, accent pieces, and switchgear arranged throughout the cabin along the lines of the new A1 subcompact. The Q3 offers an impressive array of optional toys for its size, including LED ambient lighting, adaptive headlights, adaptive cruise control, a panoramic glass roof, heated seats, keyless entry and ignition, and a variety of sound systems, topping out at the MMI navigation system with Bluetooth. All Q3s can be specified with Audi Drive Select, which lets drivers choose from multiple settings for the steering, engine, and transmission response. It also includes a new efficiency mode, which tweaks air-conditioner and cruise-control operation to maximize fuel savings.
