Zeroshift transmission is a new technology invented by Zeroshift Ltd . The company claims that its transmission is superior than other transmission in the world. It has better fuel efficiency than SMG, manual transmission, auto transmission, AMT, and CVT. It cheaper to manufacture, the weight of the transmission is lighter, and the size is compact compare to auto transmission and other transmission which has complex system such as SMG, CVT, and DSG. Zeroshift Ltd claimed that its transmission changes gear without interrupting the torque transfered to the wheel. It allows the vehicle equipped with Zeroshift to accelerate faster than vehicle equipped with other transmission because there is no shift time when changing gears. This also means that there is no sudden change in the G force and the passengers would feel more comfortable since there is no jerky feel.
