Nissan luxury car arm Infiniti will debut production versions of its powerful new 2006 M performance luxury sedans - the 4.5-litre V8 M45 and 3.5-litre V6 M35 - at the 2005 North American International Auto Show in Detroit on January 10. The M goes on sale in early spring 2005.

Infiniti will also display the Infiniti Kuraza Concept, an exploratory look at future SUV interior design. The concept combines "traditional Japanese design cues, extensive use of natural materials and modern technology to create a highly social, highly luxurious interior environment", according to the car maker.
