Second generation (SG, 2002–2007) The second generation was introduced as a 2003 model at the 2002 Chicago Auto Show, based on the new Impreza platform, featuring several fine-tune improvements over the past model. In the United States, the naturally aspirated X (previously L) and XS (previously S) were released in 2003. In 2004, the turbocharged XT trim was released. The XT model uses the same Mitsubishi Motors TD04 turbocharger used in the Subaru Impreza WRX. All Forester 2.5 L engines are of the interference engine type.
