固有振動
This transmission includes Auto Normal Mode, Auto Sports Mode, Auto ICE Mode, and Manual Mode. Auto Normal mode shifts gears automatically at low rpm to achieve the most comfortable ride and at higher rpm when driving style becomes more sporty. AutoSport Mode changes gears 40% faster than in Normal Mode, downshifts when lifting off as a corner approaches; then it activates the stability control, stiffening Skyhook suspension, and opening exhaust valves when the engine is over 3,000 rpm (in the GranTurismo S Automatic). Auto ICE mode is for low-grip conditions; it reduces maximum torque at the wheel, prevents 1st gear starts, and only allows gear changes below 1,000 rpm.
