Infiniti's next-generation G has been tipped for a Detroit auto show debut. Nissan's luxury division revealed via its Facebook page that it will be unveiling "an all-new Infiniti luxury sports sedan" at the North American International Auto Show in January.

Infiniti didn't release any further details about the next-generation G, but the timing lines up with comments made earlier this year by Andy Palmer, executive vice president of Nissan and Infiniti's Global Business Unit. In May Palmer said "the new G will arrive a year from now," which fits perfectly with a Detroit debut.

Infiniti has yet to confirm any details about the next-generation G, but the car is expected to switch from Nissan's FM platform to a new rear-wheel drive architecture sourced from Mercedes-Benz. The G will also rely of Mercedes-Benz for engines, including a new entry-level turbocharged four-cylinder and a high-performance twin-turbocharged V6 for Infiniti's range-topping IPL models.

It remains unknown if Infiniti will switch out its current 3.7L V6 for a new unit from Mercedes.

The new G should retain its current configurations, meaning the car will eventually be available as a sedan, coupe and convertible. All-wheel drive will remain on the G's option sheet.
