We've caught the sixth generation Maserati Quattroporte testing many times, but each time, the car was still heavily camouflaged. Well, not anymore! Today, our spy photographers have caught the car testing somewhere in Italy and, as seen in the images, the prototype is in less cladding then ever before.

The new Quattroporte->ke336 will be moved to an entirely new rear-wheel drive platform that will use lightweight aluminum in an attempt to reduce the car's total weight. On the exterior, it will adopt a much sharper design with elements inspired by the latest GranTurismo->ke2326 models.

Rumors say that the new Quattroporte will be offered with two new engines developed by Ferrari at the Maranello factory: a turbocharged V8 engine and a supercharged V6 engine, both mated to a ZF-sourced eight-speed automatic transmission.

The Maserati Quattroporte's official specifications will be announced in March 2013 at the Geneva Motor Show, so stay tuned!
