US-spec GT models, first offered in 1990 as a turbocharged sedan or wagon in Japan, and as a trim package for the US version in 1994, became a top level model upgrade in 1996, using the new EJ25D DOHC 2. 5 L naturally aspirated engine. "Limited" trim level editions were introduced, offering heated leather, or cloth, seats and trim and a tinted, glass moonroof. The term "Limited" appeared on the "GT", known as the "GT Limited" in 1998. The term "Limited" was used by itself on the Outback in 1998. Driver and front passenger airbags were added with the redesigned interior as standard equipment in accordance with US Federal Government regulations. 1999 marked the 30th anniversary of Subaru in America, and the last of the second generation in North America. There was a special 30th Anniversary Edition offered in the US with upgraded interior and sunroof, spoiler, alloy wheels on the "L" trim level cars. The US-spec "Brighton" trim level also carried over from the facelifted first generation version that was priced below the "L" trim option.
