Infiniti has confirmed that it will introduce a brand new luxury sports sedan at the Detroit Motor Show that will open its doors next January. Â Although the automaker has yet to confirm this, the car is widely believed to be the next-generation of the G sedan.
The next Infiniti G will ride on the same rear-wheel drive platform as the Mercedes-Benz C-Class, an arrangement that is made possible thanks to Renault-Nissan's partnership with Daimler. Â Infiniti engineers will also raid the German firm's parts bin to give the G more efficient gasoline- and diesel-burning powerplants.
In an interview with England's Autocar, Infiniti chief designer Shiro Nakamura explained that the next-generation 3-Series-fighter will be "much sportier and more dynamic than the current car."  Like the current model, the next G will be offered as a sedan, a coupe and a convertible, though only the sedan will be on hand at the Detroit show.  The two-door models are expected to bow later next year or in early 2014.
The new G range is expected to bear a proper M3 rival. Â Branded under Infiniti's IPL label, the high-performance G could use a twin-turbocharged V6 rated at well over 400 horsepower.
Following the G's official debut, Infiniti is expected to reveal an updated version of the M sedan and a production version of the LE concept.
