UPDATE: The 2014 Infiniti Q50 (G37 replacement) has been revealed. Click here for all the official details and photos.

Here’s our first official look at the first model to be launched under Infinti’s new naming strategy, where each of the automaker’s offerings will come with either a “Q” or “QX” attached to its name. This will eliminate the current alphabet soup of names at Infiniti, which may seem confusing now but will make more sense as an onslaught of new models arrive.

The model being teased in this video is the 2014 Q50 sedan, the replacement for the G37 sedan, which makes its debut on January 14 at the 2013 Detroit Auto Show.

The new Q50 is a completely new design from Infiniti, though it is expected to share many elements with the next Mercedes-Benz C Class thanks to the alliance deal between Renault-Nissan and Daimler.

From earlier spy shots of prototypes, we also know the car will borrow styling elements from the Infiniti Emerg-E and LE concept cars.

The video reveals the new headlight design of the Q50, which incorporates an LED ‘eyebrow’ similar to Mercedes’ current headlight design trend. We can see more LEDs around the main projector lamp, which looks to be adjustable.

Finally, the video also reveals the metallic growl of the Q50’s engine, which is expected to be an updated version of the 3.7-liter V-6 engine found in the outgoing G37. A four-cylinder diesel sourced from Mercedes may be offered in other markets, and a hybrid option may eventually follow as well.

Of most interest to performance fans is the possibility of a high-performance IPL version of the new Q50 sedan (the current IPL models are limited to the G37 coupe and convertible bodystyles).

Stay tuned for the Q50's reveal in two weeks. In the meantime, to see what else will be at the Detroit Auto Show, be sure to check our dedicated show hub.
