Subaru's largest sedans and wagons are redesigned for 2000, measuring six inches longer than previous Legacys on a 0.8-inch longer wheelbase. The popular Legacy-based Outback models are now a separate series, but share the Legacy's basic new design. Legacy sedans come in L, GT, and GT Limited trim, wagons in Brighton, L, and GT form. All use a new single-overhead-cam version of Subaru's 2.5-liter horizontally opposed 4-cylinder engine, which replaces the more expensive twincam design used previously. Horsepower is unchanged from '99, but there's more torque at lower engine speeds. Manual or optional automatic transmissions again team with Subaru's permanent all-wheel drive. All Legacys come with dual airbags and antilock brakes; the GT Limited sedan adds standard front side airbags, the only model where they're available, as well as a limited-slip differential for maximum AWD traction in very slippery conditions. For 2001, the low-cost Brighton model will likely be dropped, and Legacy's Outback sibling will offer a 6-cylinder engine that won't show up immediately in the Legacy line.
