One main development topic for the Honda Formula One third era gearbox was the seamless gearbox (Quick Shift), which reduced the interruption of acceleration to zero.Gearshift control provided a way to control dog damage and excessive torque, which had been issues affecting Quick Shift feasibility, and this enabled the team to realize first deployment of the Quick Shift in racing, ahead of the other teams. The search for even smoother gear shifting continued after that, and led to the establishment of a mechanism that would reduce to a minimum the torque fluctuation resulting from correlation of the torsional vibration of the driveshaft and the inertial torque generated during gear shifts.
