The 2010 Subaru Legacy is a five-passenger AWD sedan that has been completely redesigned for the new year. The base engine is a 2.5L four-cylinder engine good for 170 hp and paired with a six-speed manual. A CVT transmission is also available. Adding a turbo to the 2.5L engine bumps the power to 265 hp, and this gets linked to a six-speed manual transmission. A brand new 3.6L six-cylinder engine is also available which is mated to a five-speed automatic transmission and produces 256 hp.
