Saab taps the holdings of parent-company General Motors for its new entry-level model: a 4-dr, all-wheel-drive wagon based on the Subaru Impreza. The 9-2X gets Saab-family styling alterations, but uses Impreza's bodyshell and powertrains. Two 9-2X models are offered, both with horizontally opposed 4-cyl engines and standard AWD. The base Linear has 165 hp. The turbocharged Aero mimics the sporty Impreza WRX, with 227 hp and a functional hood scoop. Both offer a 5-speed manual transmission or optional 4-speed automatic. Antilock 4-wheel disc brakes, torso- and head-protecting front side airbags, and 16-inch wheels are standard; the Aero is available with 17s. Leather upholstery and a sunroof are options. The 9-2X is aimed at a more upscale market than Impreza, and it has different nose, tail, and wheels. The interior design is shared, but the 9-2X gets different upholstery and Saab's active front-seat headrests designed to minimize whiplash injury.
