The Nissan GT-R may seem born to be a two-door car, but the model first started out as a four-door car in 1969 and was followed by a two-door version the following year.  By adding a four-door Nissan is hoping to promote to a wider customer base. Technologies that are expected to follow to the four-door car are tire pressure monitoring system, ABS with electronic brake-force distribution, traction control system with vehicle dynamic control, lane departure warning that beeps, lane departure prevention through selective brake application, and intelligent cruise control, with distance control assist that will maintain following distances at speed.
