The Tundra is all new for 2007. Larger than its predecessor, the Tundra offers three cabs, three wheelbases, three bed sizes, and three engines, including a new 381-hp, 5.7-liter V-8. Anti-lock brakes, a limited-slip rear differential, front-seat side air bags, side curtain air bags, and electronic stability control are standard on all Tundras, from the new entry-level DX model all the way up to the top-of-the-line Limited.
