Mazda is to preview its next generation 6 (Atenza in Japan) line with this Takeri concept at the Tokyo motor show in November.

The PR blurb says the car is designed to express “an intuitive sedan identity” and “an overwhelming emotional beauty” as the latest platform for Skyactiv technology and has a new, efficient diesel engine and new light weight and aerodynamic technologies.

It also features the i-stop idling stop system and the automaker’s first regenerative braking system.
