Mazda has announced that the facelifted version of the 2010 Mazda Atenza will immediately begin its sales in Japan. The Mazda Atenza however will appear at the Geneva Motor Show as the 2010 Mazda6.

The engines for the Mazda6/Atenza will include a new, more efficient petrol 2.0 liter DISI1 unit replacing the current 2.0 liter engine. The MZR 1.8- and 2.5-liter petrol engines have also been updated. The MZR-CD 2.2 liter turbo diesel which is capable of 127 to 178 horsepower has modifications to make it more efficient and clean. All the engines options will be offered in Europe; however the MZR 1.8-liter will not be sold n Japan.

The mid-size car comes as a four-door sedan, five-door, or five-door wagon.  Its “grinning” front end, including a new front bumper, now brings the Mazda6 inline with the Mazda3 and recently revealed Mazda5.  More dramatic changes at the back can be seen, where the car now sports a completely remodeled bumper, light clusters, and tailpipes.  Changes were not just made to the outside, as the car now has a single color interior instead of the contrasting tones in the 2009 model.  It gives the interior of the car a cleaner look.

The Mazda6 will get its international premiere at the Geneva Motor Show in March, and will go on sale in Europe soon after.
