The Mazda 6, produced from 2002 to 2008, represents a significant entry in the mid-size sedan and wagon market, embodying Mazda's 'Zoom-Zoom' philosophy with a focus on driving dynamics and engaging performance. Available in sedan (GG chassis code) and wagon (GY chassis code) body styles, this generation offered a choice between efficient 2.0L (LF-DE) and more powerful 2.3L (L3-VE) MZR engines, paired with either a 5-speed manual or a 4-speed automatic transmission. Known for its sharp handling and a comfortable ride, the Mazda 6 competed with established players like the Toyota Camry and Honda Accord, often praised for its more sporting character and practical wagon variant. Safety was a key consideration, with models earning high ratings in crash tests, especially when equipped with optional side and curtain airbags, and featuring standard Anti-lock Braking System (ABS) and Electronic Brake-force Distribution (EBD).
