Nissan's premium marque developing a new full-sized SUV and a Q-badged flagship sedan. Also in the works is a mid-sized sedan to take on the BMW 5-series and an electric small car to crowd into the A3/1-series/A+B-Class luxury compact segment.

Well, it seems Infiniti is intent on making itself a major player in the premium segment with the development of several new models. So, let's see what Autocar has to say about them.

First up, the mag is reporting that Infiniti will be developing a new medium-sized luxury sedan to compete against the likes of the BMW 5-series. The model is slated to make its debut at the 2010 Geneva motor show and will be called the M(number to be announced at a later date). The model is supposed to come with the brand's 3.7 liter V6 gasoline/petrol powerplant, as well as a new 3.0 liter V6 turbocharged diesel.

Also in the works is a new QX flagship SUV to replace the current QX56. It will be very large and aimed at markets such as the US and Russia, with availability in Europe limited to special ordering. By 2015, there may be another 7-seat SUV too, one that sits lower and comes with a sleeker roof-line, but nothing is assured here.

Two new sedans are also in the pipeline for a 2012 release. A new Q-badged full-sized limousine, to be the brand's flagship model, and the next generation G37 which will likely carry a different name.

Lastly, is an electric car set to rival the BMW 1-series. It will likely be a rear or all-wheel drive and Infiniti wants to have it on the market by 2012.

Good luck with all that.
