Nissan is considering building a four-door version of its GT-R supercar for its Infiniti luxury division, a new report finds. A Nissan official revealed that the Japanese automaker was considering an Infiniti-badged version of the supercar, but this is the first time it's been revealed that the new model could be a four-door sedan.

The new car would be based on the GT-R's Front Midship (FM) platform, but Motor Trend says that the car's architecture would have to be changed so much to accommodate two more doors and a usable backseat that Nissan refers to the Infiniti-badged GT-R's platform internally as Premium Midship (PM).

However, the extended model would still utilize the GT-R's suspension and powertrain mountings, as well as the car's 480 horsepower twin-turbo V6, all-wheel drive and rear-mounted dual-clutch transmission.

But because of the extra two doors, the new car would require new sheetmetal, raising the price of production. If the four-door Infiniti version of the GT-R gets the green light, look for it to command a $3,000 to $5,000 premium over the Nissan version.

The Infiniti version of the GT-R would also give the luxury marque a halo car, and allow it to compete with BMW's M-division and Mercedes-Benz's AMG.
