Infiniti to debut new sports sedan in Detroit

The sports sedan is expected to be the next-gen G sedan.

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. 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. 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. 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.
