Infiniti's G replacement is nearly here.

Infiniti has released a new teaser video featuring its upcoming Q50 sedan. The Q50 - which will be the first Infiniti model to be releases under Infiniti's new naming scheme - will debut at the North American International Auto Show in Detroit on January 14.

The teaser video doesn't give away much, highlighting only the sport sedan's new headlight. From what we can see, however, it appears as though the Q50 will sport a more aggressive look than the current G sedan. The teaser video also reveals a new light band that forms the headlight's "eyebrow", which could become a new Infiniti design cue.

Not much else is known about the Q50, but the sports sedan is expected to switch from Infiniti's FM platform to a new rear-wheel drive architecture sourced from corporate partner Mercedes-Benz. A new turbocharged four-cylinder will stand as the entry point to the Q50 range, but it remains unknown if the G's current 3.7L V6 will remain on offer. Infiniti has confirmed plans for a new 550 horsepower 3.0L V6 earmarked for a flagship sedan, so it's possible that mill could end up beneath the hood of a high-performance Q50 IPL model.

Be sure to check back for more details and live images from the Detroit auto show next month.
