Replacing the 626 for 2003, the Mazda 6 is a slightly larger compact sedan with fresh styling and more power. The base "i" model uses a 160-hp 4-cyl engine vs. a 125-hp 4 cyl in the 626. The uplevel "s" has a 220-hp V6 vs. the 626's 165-hp V6. Manual transmission is standard. The optional automatic is a 4-speed unit on 4-cyl models, a 5 speed on V6s; both have a separate gate for manual shifting. All 6s have 4-wheel disc brakes. ABS with traction control is standard on V6s, optional for 4-cyl models. Front side airbags with head-protecting curtain side airbags are optional. So is a Sport Package with 17-inch wheels vs. 16s, plus a rear spoiler and other aero add-ons. All models come with a single-disc CD player, tilt/telescopic steering wheel, and split/fold rear seatback. Optional are a sunroof, leather upholstery, heated front seats, and in-dash CD changer. Mazda says the 6 will add wagon and 4-dr hatchback body styles for model-year 2004.
