Model Overview

The second-generation Mazda 6 adopted a more aggressive Nagare ("flow") design language, which became Mazda's signature style in the late 2000s. The car appeared more dynamic than its predecessor thanks to sharp body lines, narrow headlights, and a large grille.

The interior was more spacious, with higher-quality materials. Top trims offered leather seats, dual-zone climate control, and a navigation system. Safety met Euro NCAP standards (5 stars in 2008).

Suspension: Independent setup (front MacPherson struts, rear multilink). Compared to the first generation (GG), engineers improved noise insulation and ride comfort.

 

Interesting Facts

  • Mazdaspeed6 (Mazda 6 MPS) – the most powerful version with a 2.3L turbo engine and AWD. Only produced as a sedan (2006–2007), but sales were limited due to high fuel consumption and niche appeal.

  • Special Editions: Europe got a "Sport Black" model with black wheels and exclusive trim. Japan had a "20B" rotary-engine version (for racing teams only).

  • No SkyActiv Tech – unlike the third gen (GJ), the Mk2 used traditional MZR-series gasoline and diesel engines.

  • Russian Market: The Mazda 6 GH was sold in Russia from 2008 but had moderate popularity due to its high price (vs. rivals like the Ford Mondeo).

  • Racing Heritage: The Mazda 6 competed in endurance races like the 24 Hours of Nürburgring, proving its reliability.

 

Conclusion

The second-gen Mazda 6 (GH) balanced sportiness and comfort without being revolutionary. Its strengths included body style variety, reliable engines, and sleek styling. Today, it remains an affordable used car option, though outdated electronics and rust issues require attention when buying.
