Nissan and JATCO Develop Innovative, Next-Generation CVT TOKYO (July 22)--Nissan Motor Co., Ltd., a long-time leader in the development and application of CVT (Continuously Variable Transmission) technology, and its affiliate transmission supplier JATCO Ltd. today announced the joint development of a new generation of compact and lightweight CVTs.
Next-generation CVT The next-generation CVT design features an innovative structure combining conventional CVT belt operation with an auxiliary gearbox and a significantly increased gear ratio range. The new CVT is scheduled to appear in compact Nissan vehicles worldwide in the near future. Major features of the new CVT are: World's highest transmission ratio for quicker starts and acceleration Compact and lightweight Superb drivability "Nissan believes the CVT has very good potential as a leading technology for raising the fuel efficiency of internal-combustion engine systems," said Shuichi Nishimura, corporate vice president, Nissan Powertrain Engineering Division. "Nissan first began applying CVT technology in 1991 and has been continuously evolving CVTs, engine-cooperative management and other systems, and expanding their use in Nissan vehicles. The need to improve fuel economy, with the resulting reductions in CO2 emissions motivated us to step up our efforts in the joint development with JATCO of this next-generation CVT." JATCO, the worldfs leading CVT manufacturer, is the only company that offers a full range of CVTs for applications from mini-vehicles up to 3.5-liter V6-equipped cars. The company produces 43 percent of CVTs made globally. "The revolutionary structure of the next-generation CVT, with its auxiliary transmission, not only raises the transmission ratio, reduces weight and adds fuel efficiency, its compact design also expands its applicability to a broader range of vehicles,h said Yo Usuba, vice president, JATCO. gWe believe it is an excellent choice for automakers seeking to raise the fuel efficiency of their smaller cars." Based on the mid-term environmental program "Nissan Green Program 2010," Nissan and JATCO have achieved sales of 1 million CVT-equipped vehicles, as well as introducing 7-speed automatic transmissions to improve fuel efficiency. The companies will continue to introduce effective technologies and products into the market in pursuit of a sustainable mobility society. * Excluding DCTs and manual transmissions. - end - |
