Nissan Launches Next-Generation CVT

Nissan and JATCO today revealed their next-generation CVT (Continuously Variable Transmission) which is said to be lighter and provide better results than its predecessors. The new CVT combines conventional CVT belt operation with an auxiliary gearbox and increased gear ratio range, Nissan explained in a release. It is expected to arrive in the market on Nissan vehicles to be launched in the near future.

The Japanese manufacturer says the new CTV provides the world's highest transmission ration for quicker starts and acceleration as it raises available ration from current 6.0:1 to 7.3:1, more than 20 percent higher than other CVTs. Additionally, the new unit is lighter than the other CVTs by around 13 percent and is capable to provide "super drivability", as Nissan stated. It features Adaptive Shift Control (ASC) for improved performance by selecting the best ratio for startup, acceleration and uphill or downhill driving.

"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."

"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," said Yo Usuba, vice president, JATCO. "We believe it is an excellent choice for automakers seeking to raise the fuel efficiency of their smaller cars."
