Nissan's latest Sport Sedan concept is one of the most impressive world premieres at the 2014 Detroit motor show. We're not sure if it previews the next generation Maxima though.

Nissan never mentioned the word "Maxima" in the press blurb, but says that the study applies to "real sports car performance standards and new design philosophies to a 4-door sedan", and that it "previews a future production vehicle intended for owners with a passion for cutting-edge design and driving dynamics".

It's also very close in dimensions to the current Maxima at 191.7 in. (4,870 mm) long, 75.3 in. (1,912 mm) wide, 54.3 in. (1,378 mm) tall, with a wheelbase of 111.2 in. (2,825 mm) – to be precise, it's a hair bigger in all directions but height.

The study comes with a 3.5 liter V6 producing more than 300 horses backed by a sport tuned Xtronic CVT driving the front wheels.
