Maserati has announced a new version of its Quattroporte model, with a sporty updated design, set to premiere at the Detroit Motor Show in 2013.

The Italian carmaker plans to unveil three new models in 2013, starting with the new Quattroporte, which will be on display in Motor City between January 19 and 27.

Aside from what can be gleaned from a few pictures, little information has been released regarding the specs and other details on the new generation four-door GT.

The signature characteristics of the previous model will remain, but the design will be sportier and modernized, and the car will be propelled by a brand new engine.
