New engines and transmissions will soon be available on upcoming Toyota models. The Japanese automaker recently announced that new powertrains will soon make its way to vehicles that use the TNGA platform. Currently, the TNGA family is used on all modern Toyota models from the Prius up to the Lexus LS and LC.

New engines, transmissions, coming to Toyota vehicles soon

For the engines, Toyota stated that there will be a new 2.0-liter, direct injection, inline-4 called Dynamic Force and a 2.0-liter hybrid system called Toyota Hybrid System II. To send power to the wheels, there are two new transmissions – a direct shift continuously variable transmission (CVT) and a new 6-speed manual transmission.

Starting with the 2.0-liter Dynamic Force engine, it uses Toyota's latest technology to improve efficiency and lower emissions as well. Specifically, it achieves a higher thermal efficiency hence the higher power output and reduces energy loss.

Together with the new Dynamic Force engine, Toyota has also developed a new hybrid system for 2.0-liter engines. It incorporates technology used in the fourth-generation Prius in order to reduce size and weight. At the same time, it is also said to improve driving performance while retaining fuel efficiency.

To put the power down efficiently, Toyota also developed a new transmission called Direct Shift-CVT. Unlike a conventional CVT which uses only a belt or chain, Direct Shift-CVT uses a launch gear in order to improve belt efficiency on lower gear ratios, where the CVT is at its least efficient. It then switches to the regular belt drive at higher speeds, which is said to maximize efficiency. A more detailed explanation can be found in the video above. 

Meanwhile, the newly developed 6-speed manual transmission is more of an update to the existing transmission currently offered. It has a reduced weight and length to help boost fuel efficiency and features iMT (Intelligent Manual Transmission) controls.

Toyota did not say which models will receive the upgraded powertrains nor when it will debut. A possiblilty would be at Geneva together with the upcoming Supra. They did mention, however, that they will expand the number of models which use the new powertrains this year. By 2023, Toyota expects to have new TNGA-based powertrains installed in approximately 80-percent of vehicles sold globally.
