Both engines were paired with a five-speed manual transmission, although a four-speed automatic transmission was available in the WRX. The Symmetrical All-Wheel Drive (AWD) system, a defining characteristic of Subaru vehicles, ensured excellent traction and handling in all conditions. The WRX and STI also featured a sport-tuned suspension, high-performance brakes, and a driver-focused interior with supportive sport seats and a racing-inspired instrument panel. The 2008 Impreza WRX and STI models offered a blend of performance, practicality, and affordability, solidifying their position as iconic sports cars in the automotive market.
