Toyota's New Hybrid Is Serious On Cutting Emissions

Toyota has unveiled new powertrain technologies—including one hybrid engine—that all get serious about cutting greenhouse gas emissions.

New technology is driving the global economy forward, and Toyota is no exception. They’ve come out with a bevy of new powertrain tech that they say will cut their global fleetwide emissions by 18 percent.

First up is a new continuously variable transmission (CVT) that will have a “launch gear” which improves efficiency at lower engine RPMs. This will make for a quieter ride as the car won’t have to rev its engine to get up to speed. It’ll also have a 15 percent larger spread between ratios and have 20 percent improvement on shift speed compared to conventional CVTs.

All of this combined improves fuel efficiency by 6 percent over existing transmissions, according to Toyota.

Next up is a new six-speed manual transmission that is lighter, more compact, and quieter than existing manual transmissions. On top of that, it will have a dedicated reverse-gear synchronizer, as well as a Toyota’s Intelligent Manual Transmission (iMT) which will automatically match engine RPMs while shifting gears. This should give drivers a smoother, easier shift between gears.

Third is Toyota’s Dynamic Force engine, which sounds both dynamic and forceful. It’s a 2.0-L direct injection inline 4-cylinder engine that will provide “equal or greater power performance while realizing best-in-class fuel economy” when paired with the new CVT.

And finally, there’s the 2.0-liter Toyota Hybrid System II (THS II), a hybrid engine that is lighter and more efficient than the previous hybrid found on many of Toyota’s cars, including the Prius.

All of these technologies are designed to work on Toyota’s New Global Architecture, which is used on the current Corolla, CH-R, and is planned for most of their future fleet.

There’s also a new Dynamic Torque Vectoring AWD and E-Four 4WD system—both of which Toyota doesn’t provide much detail on, likely due to the fact the technology hasn’t been patented yet and they don’t want anyone to swipe it. But they assure everyone that the technology is going to be lighter and more efficient and very impressive.

Expect to see all this fun stuff come to Toyota vehicles in the coming years.

All in all, Toyota will produce 17 versions of nine engines, 10 versions of four transmissions, and 10 versions of six hybrid systems by the end of 2021. Toyota is a very busy company.
