A popular model for fleet customers, the Mazda6 comes in estate or hatchback body styles and is priced from £16,995 on-the-road.
In all, 12 variations of the hatchback and seven estate models are available because of the choice of six engines and four trim levels.
The three diesel engines, including a 2.2-litre diesel in 129PS and 180PS variations, are now being made available during May.
Petrol models, such as the 155PS 2.0-litre DISI and 2.0-litre Sport, have been available since the launch in mid-March this year.
Across the six engines, Mazda has improved average fuel economy in the Mazda6 by between 3.2 and 4.1 per cent and reduced CO2 emissions by between 4.4 and 4.8 per cent.
Mazda has been careful to reduce CO2 on the estate models to offset tax increases on company cars introduced in April.
Peter Allibon, Fleet and Remarketing Director, Mazda UK, says the Mazda was the model that put the brand on the ‘fleet map’, and the manufacturer predicts it will sell over 10,000 in the next 12 months, a figure likely to be boosted by fleet sales.
The Mazda6 has been given some cosmetic upgrades to appeal to private buyers as well, including a refreshed exterior including a choice of eight exterior colours in standard or metallic paint.
Mark Cameron, Sales Director, Mazda UK, said: "Distinctive styling has always given the Mazda6 ‘stand-out’ looks from other family cars and the refreshed model has an even more sophisticated appearance."
Inside, there is now a wider range of interior trims available in the form of part leather sports trim and full leather trim on top specification models.
The four specifications – S, TS, TS2 and Sport – are retained from the previous model but Mazda has added smart turn indicators and Emergency Stop Signal (ESS) on all models.
Upgraded for the 2010 model year, the new Mazda6 will refresh the range as it competes with rivals such as the Citroen C5 and Ford Mondeo.
The Mazda6 in hatchback and estate variations is priced from £16,995 to £23,445 on-the-road and is available now in UK showrooms.
