For 2004, the Subaru vehicle line-up packs an extra layer of power thanks to turbocharged performance. The Forester crossover wagon and truck-like Baja in the Subaru line-up gain power from a new 210-horsepower, turbocharged 2.5 liter engine. The Subaru Impreza receives a new front end treatment that replaces the less-than popular oval-shaped headlights. Two years after the introduction of the second generation Subaru Impreza in the United States, an all-new WRX STI has finally made it on the continent. The 2004 Subaru Impreza WRX STI features 300 horsepower delivered from a turbocharged 2.5-liter engine. A large rear spoiler and sizable hood scoop are also married with the Impreza WRX STI model. In honor of Subaru's 35 years in the United States auto market, Subaru has prepared 35th Anniversary Edition versions of the 2004 Legacy and Outback with special equipment.
