Toyota says it plans to bring “17 versions of nine engines, 10 versions of four transmissions, and 10 versions of six hybrid systems” to market by 2022. If this seems like an onslaught of powertrain news, well, buckle in. Hybrid all-wheel-drive models, which in Toyota’s world typically feature a two-motor hybrid transaxle powering the front axle and an electric motor powering the rear axle, will get a more powerful rear-axle motor in the new E-Four AWD system. 2018 Toyota Camry SE 2.5L Tested: The Last Time We Enjoyed a Camry This Much? NeverĬoming soon to a TNGA-platform Toyota near you is a new all-wheel-drive system. It will have torque-vectoring capability with the ability to distribute torque between the left and right rear wheels, bringing a bit of high-tech verve to future all-wheel-drive Toyotas.Is Toyota Bringing the Celica Nameplate Back from the Dead?.Cowa-TNGA! Toyota’s New Modular Platform Reaches Production.Toyota claims the new transmission enhances both performance and fuel economy compared with its existing CVT, and with an even wider ratio spread. The difference is that, in the Jatco unit, the car always starts from a stop with the CVT engaged. In that CVT, engine torque enters the CVT as usual but exits on the output shaft to an “auxiliary gearbox” that is, in effect, a two-speed transmission. Toyota claims this is “unprecedented,” although we found some precedent in transmission supplier Jatco’s CVT7. As vehicle speed builds, the transmission then shifts out of launch gear and continues as a CVT. In an effort to give its new CVT the feel of a conventional automatic transmission when accelerating from a stop, Toyota has added a “launch gear.” Essentially, this fixed ratio-not a simulated gear as in some CVTs-is just like a normal transmission’s first gear. The transmission is more compact and lighter than Toyota’s current unit and incorporates rev-matching capability. Presumably, the 2.0-liter four will be compatible with the new six-speed manual transmission Toyota has developed for “global needs”-fingers crossed that it comes stateside. That pushes the boundaries of gas-engine thermal efficiency, and the version that will power future Toyota hybrids does even better, at a claimed 41 percent. The basics, however, are as follows: The Dynamic Force engine will have Toyota’s D4-S port and direct fuel injection as well as an electronically controlled thermostat and an electrically driven water pump it also is said to be capable of an incredible 40 percent thermal efficiency. Toyota offers few specifics on its new 2.0-liter Dynamic Force gasoline inline-four, likely because it will ultimately end up in a plethora of cars and crossovers in various states of tune. Among the first developments out of that gate will be a new 2.0-liter four-cylinder engine called Dynamic Force for both gasoline and hybrid vehicles, a new six-speed manual transmission, two new all-wheel-drive systems, and-most intriguing of all-a new continuously variable automatic transmission. Toyota’s buildout of its new Toyota New Global Architecture (TNGA), headlined by the latest Prius and Camry, has progressed to powertrains.
