Mazda has upgraded specifications across the Mazda6 range, which now includes DAB radio as standard.

The model, on sale from early in the new year, priced from £19,795 to £28,795 on-the-road, is the first Mazda to include DAB. On previous models, the radio technology has not been available as an option.

The 2015 Mazda6 model range is available in five grades; SE, SE Nav, SE-L, SE-L Nav and Sport Nav. Mazda are to offer a choice of nine diesel and seven petrol Saloon variants, and nine diesel and three petrol Tourer versions, equipped with either six-speed manual or automatic transmissions.

SE and SE-L grades now include Mazda's first electronic parking brake, a coming/leaving home headlamp function, the company's Multimedia Commander with separate volume dial for safe, intuitive interactivity and infotainment control, manual driver and front passenger seat height adjustment.

A new 7-inch, full-colour, centre console touch-screen incorporates DAB radio -a first for Mazda, and MZD Connect - first featured on all-new Mazda3. Paired with a smartphone, MZD Connect makes it easier to take advantage of functions such as internet connectivity and access to social networking services.

Top-of-the-range Sport Nav models benefit from new exterior features including a re-styled front - new grille and signature wing design - incorporating powerful LED headlamps including LED daytime running lights, LED foglamps, new LED tail lamps, and new 19-inch bright alloy wheels.

On board, a six-way power adjustable front passenger seat, vinyl leather knee pads, a new head-up display and an Integrated Navigation system complete the Sport Nav's enhanced standard equipment specification.

The Head-up Display projects the most important real-time driving data directly into the driver's forward field of view. The new Integrated Navigation system offers greater accuracy, improved search features and three years of free map updates.

Sport Nav grade options now include stone leather upholstery (in lieu of black) and an evolution of the Safety Pack incorporating several new innovative technologies.
