The Impreza S203 created the standard for STI complete cars that continues to this day. Petter Solberg, who was competing in the WRC (World Rally Championship) with the Subaru World Rally Team at the time, also participated in the development, and development was carried out with the aim of achieving even greater heights. The engine was subjected to precision overhaul and supercharged with a ball bearing turbine that provides excellent response, achieving 320 PS/43.0 kg-m. Not only the suspension, but also the arms and stabilizers are specially designed, achieving high-level road holding performance. With the arrival of the S203, which raised the overall power of the Impreza to a higher level, the name of STI complete cars became known around the world.
