Nissan GTR 2012


Transmission        

Dual clutch 6-speed transmission with three driver-selectable modes; each transmission hand-crafted in a clean-room environment:
     Normal – for maximum smoothness and efficiency, with gearshifts in less than 0.5 second
     R-Mode – for maximum performance with the quickest shifts (as fast as 0.2 second)
     Save – alters the transmission characteristics for gentler torque delivery for smooth driving and slippery surfaces
       
Fully automatic shifting or full sequential manual control via steering column-mounted paddle shifters
       
Downshift Rev Matching
Predictive pre-shift control (in R-Mode) preselects the next gear change based on throttle position, vehicle speed, braking input and other information
