Saab tapped 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 received Saab-family styling alterations, but used Impreza's bodyshell and powertrains. Two 9-2X models were offered, both with horizontally opposed 4-cyl engines. The base Linear had 165 hp. The turbocharged Aero was similar the sporty Impreza WRX, with 227 hp and a functional hood scoop. Both offered a 5-speed manual transmission or optional 4-speed automatic. ABS, front side airbags, and curtain side airbags were standard. Leather upholstery and a sunroof were optional. The interior design was shared, but the 9-2X received different upholstery and Saab's active front-seat headrests designed to minimize whiplash injury.
