The Mazda Takeri has finally made its much-anticipated debut at the 2011 Tokyo Motor Show and it quickly created quite a stir. As CarBuzz previously reported last month, the pre-production concept is the next generation Mazda6 preview. Mazda is calling the Takeri a 'four-door coupe,' and uses a SKYACTIV-D (clean diesel) engine, along with an ultra-high tensile steel chassis, standard stop-start and aerodynamic pieces.

The new Mazda6 will use the i-ELOOP regenerative braking system, which the Japanese manufacturer estimates the concept will be able to travel roughly 932 miles between fill ups. The fuel-efficient model's lightweight 2.2-liter turbodiesel engine can put out 173hp and 310lb-ft of torque.

In addition to being more efficient and cleaner than its predecessors, the new diesel motor features the lowest compression ratio ever for a Mazda-produced diesel motor. It will be mated to a new torque convertor automatic transmission. The Mazda Takeri concept is currently on display now at the 2011 Tokyo Motor Show. It could arrive as early as the 2012 Paris Motor Show and will be dubbed the new Mazda6. The Mazda6 should launch as a 2013 model year.
