The 2006 Subaru Impreza, part of the vehicle's second generation, is a standout compact car offering both sedan and wagon body styles. Engine options include a 173-hp 2.5-liter flat-four for the 2.5i trim and a turbocharged 2.5-liter flat-four offering 300 hp in the WRX STI version. All trims come with standard all-wheel drive, a Subaru staple, and pair with a 4-speed automatic or 5-speed manual transmission. Although the tech features are basic by today's standards, the Impreza included a six-speaker sound system, CD player, and optional navigation system. Safety features include front-impact airbags, side-impact bars, and an anti-lock brake system.
