Mazda6 Generations Overview

First Generation (2003–2008): The Global Challenger Arrives

The Mazda6 launched in 2002 for the 2003 model year, replacing the 626 and marking a radical shift in Mazda’s design philosophy. Labeled the “Zoom-Zoom” era, this generation embraced a more spirited sports sedan identity.

• Transmission: 5-speed manual, 4/5-speed automatic
• Trims: i, s, Sport, Grand Touring
• Mazda6 Problems: Early V6 models reported transmission problems and common rust spots, especially in the wheel wells and underbody in salt-prone regions.
• Fun Fact: The Mazda6 also debuted as a wagon and hatchback in certain markets, though U.S. buyers primarily got the sedan.

2003 Mazda6 Review: Car and Driver praised its lively performance and responsive handling, calling it "a serious threat to the Accord and Camry."

Second Generation (2009–2013): Bigger and Bolder for the U.S. Market

Arguably the best Mazda6 era, this generation introduced SkyActiv Technology for engines, chassis, and transmissions, aiming to maximize fuel efficiency and performance.

Mazda6 Pricing, Resale & Discontinuation

• Mazda6 Price: MSRP ranged from ~$22,000 to ~$36,000 depending on trim and year

Future of Mazda6: RWD and Inline-6 Rumors

Speculation about a Mazda6 RWD inline 6 sedan continues to swirl. Reports suggest Mazda is developing a premium rear-wheel-drive platform with a new inline-six engine paired with SkyActiv efficiency. If released, it could revive the Mazda6 as a legitimate luxury contender.
