Subaru's largest all-wheel-drive sedans and wagons were redesigned for 2000. New styling added six inches to length and one inch to width, on a wheelbase about an inch longer than before. SUV-flavored Outback wagons, which had accounted for 65 percent of recent sales, became a separate model line, but shared the basic Legacy design. Those wagons featured a raised roofline. Outback sedans also were offered. Both Outback models had an elevated suspension that provided 7.3 inches of ground clearance--an inch more than the Legacy. Legacy sedans came in L, GT, and GT Limited form. Wagons were offered in Brighton, L, and GT trim. Outback wagons came in base and Limited form, while only an Outback Limited sedan was available. All models retained Subaru's 2.5-liter horizontally opposed four-cylinder engine, which switched from dual-overhead cams to the less-costly single-cam format and received various internal modifications to produce more torque at lower engine speed. Horsepower was unchanged at 165. A five-speed manual gearbox was standard, with a four-speed automatic transmission optional. Outback sedans came only with automatic. Legacy GT models got a limited-slip rear differential to enhance traction in very slippery conditions. Front seatbelt pretensioners and antilock braking were standard. Side-impact airbags were standard in the GT Limited sedan and Outback Limited, but not available in other models. Rivals to the compact Legacy included the Mazda 626, Mitsubishi Galant, and Volkswagen Passat. Outback went against the Audi A4, Saturn L-Series, and Volkswagen Passat.
