According to MotorTrend, Nissan might start working on a four-door sedan based on the GT-R platform. If build, it will be sold under the Infiniti badge.
The four-door sedan will share the same hardware as the Gt-R, including the 480-horsepower twin-turbo 3.8-liter VR38 V-6 engine, all wheel drive, and the rear-mounted six-speed DSG-style auto-clutch transmission.
But even so, a sedan version will require a new bodyside, plus expensive revisions to the carbon fiber intensive front structure. Thi will mean an extra $3000 to $5000.
Also the magazine reports that Americans and European customers will never pay $85,000 for a sedan with Nissan badges. This is why they believe it will come under the Infiniti badge.
Even more this kind of sedan would help Infiniti to compete in the performance sedans market.
