The Nissan GT-R’s 6-speed dual-clutch transmission shifts incredibly quickly. How? Inside the transmission, there are separate clutches for the odd (1st, 3rd, 5th) and even (2nd, 4th, 6th) gears. When the car is in an odd-numbered gear, the adjacent even-numbered gear is “pre-selected” – ready to make the shift immediately. The transmission is so smart, it even “blips” the throttle on downshifts to match rpm.
