We have the full rundown on the 2010 Mazda Atenza, now on sale in Japan. Will it be any different than the European Mazda6? Photos and details inside.

Mazda announced today that sales of the facelifted version of the 2010 Mazda Atenza would begin immediately in Japan.  The car will be introduced internationally at the Geneva Motor Show as the 2010 Mazda6.

The mid-size car comes as either 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, 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.

Engine offerings on the car include a new, more efficient petrol 2.0-liter DISI1 unit replacing the current 2.0 engine.  The MZR 1.8- and 2.5-liter petrol engines have also been updated a bit.  The MZR-CD 2.2-liter turbo diesel, on offer ranging from 127 to 178 horsepower, has modifications to make it more efficient and clean.  All six of the engines choices will be available in Europe, but the MZR 1.8-liter will not be sold in Japan.

Adaptive lighting, hill assist, and an adjusted chassis round out the changes.  The Mazda6 will get its international premiere at the Geneva Motor Show in March, and will go on sale in Europe soon after.
