The model, sold as the Mazda Atenza in Japan, was one of the first models to be designed using Mazda’s now famous ‘Zoom Zoom’ design language in 2002.
Within eight years, it has become the second-quickest Mazda car to reach the two million mark since the new design philosophy after the Mazda3 supermini.
Now in its second generation, the car is expected to sell even more models from next year when it is given a facelift to compete against both volume manufacturer rivals such as the Ford Mondeo and the bottom end of the more premium saloon sector.
The 2011 model features a sportier feel to the tweaked front grille and a range of more efficient and cleaner engines – most noticeably the more refined 2.0-litre DISI petrol engine.
All Mazda6 cars are built in the US, Japan and China, but cars sold in Europe have been redesigned to suit European customers and roads. The second generation model, released in 2007, was given a top five-star EuroNCAP rating when it was first introduced.
Thanking the two million buyers of the Mazda6 since its launch, Seita Kanai, Mazda’s senior managing executive officer in charge of R&D said, “The Mazda6 is one of the core models which helped establish Mazda’s brand image globally.
"I was the first generation model’s development program manager, and I still have a special fondness for this terrific car."
The Mazda6 has won over 130 global motoring awards, most recently by CAP Monitor, which revealed the model has class-leading residuals because of its high reliability and understated style both inside and out.
Sales of the Mazda6 have been strong this year, with around 164,000 units sold globally – a huge improvement on the same period last year.
