A New Breed of Toyota Engine, Transmission, and All-Wheel Drive Systems Coming Your Way Real soon

For those of us who grew up with Toyotas, the terms 5k, 12R-M, and 4A-E 16-valve are very familiar. These refer to the engines found in older models like the Lite-Ace, Corona Silver Edition, and 1988 Corolla, respectively. Then there are the 2T mills that can be found on more performance-oriented models like the Corolla Liftback of the 1980s.

Whatever the engine type, these motors are symbols of durability that have made Toyota what it is today-a favorite among many a Filipino and pretty much every motorist the world over. But like any dynamic brand, the Japanese marque is constantly hard at work ensuring that it keeps up with the changing times. This is why it has come up with a host of new powertrain components that aim at efficiency and improved driving dynamics.

The new Direct Shift Continuously Variable Transmission, for instance, takes the existing belt-driven CVT that’s tuned more for efficiency and makes it more direct for improved responsive. Toyota adds a launch gear that helps smoothen out take-off and also increase efficiency. Apart from this, the new gearbox gives a wider gear range, better gear tracking,  and reduced mechanical loss—or that power that is wasted due to transmission operation. In short, you get a tranny that will help bring out the most in your vehicle and help improve fuel efficiency.

Besides the new CVT, Toyota has likewise come up with a new 6-speed manual transmission. This new row-it-yourself gearbox is 7kg lighter and 24mm shorter than existing trannies. This helps in the vehicle’s fuel efficiency and drivability. Speaking of which, the new Intelligent Manual Transmission adjusts the engine revs to help give smoother shifts—no matter what the driving situation.

Toyota has likewise come up with a pair of 2.0-liter mills that can be used for both gasoline and hybrid applications. The new 2.0-liter Dynamic Force gasoline engine achieves greater thermal efficiency and reduces energy loss. This allows it to produce increased power and torque at all engine speeds. Moreover, it will meet future emissions regulations in various locations around the world.

As for the hybrid system, the 2.0-liter hybrid drive is an improved version of what can be found in the current, fourth-generation Prius. It is lighter and smaller yet has a few neat tricks up its cylinders. One is the reduction of engine rotation and increased ability to draw more battery power during acceleration. This helps give a more linear driving sensation—unlike the golf kart-like feeling of older electric and hybrid vehicles.

Rounding things out is a pair of all-wheel drive (AWD) systems that are aimed at fuel efficiency and better off-road ability. The Dynamic Torque Vectoring AWD utilizes torque vectoring technology that steers the left and right rear wheels independently of each other. This helps provide a more direct steering response.

 The system also uses the world’s first ratchet-type dog clutch for both front and rear axles. In layman’s terms, this stops power from being transmitted to the rear axle when in 2WD mode, thus improving fuel economy. The new AWD system also promises exceptional off-road driving ability no matter what the surface.

While the aforementioned system is used for gasoline vehicles, hybrid offerings will soon benefit from the E-Four AWD. This one sends around 30% more torque to the rear wheels, helping to improve performance both on- and off-road. And thanks to AWD Integrated Management, both these drivetrains integrate engine, transmission, braking, steering, and AWD systems to provide more responsive driving dynamics on all surfaces and conditions.

Toyota plans to have the New Global Architecture-based powertrain units on roughly 80% of its Toyota and Lexus vehicles by the year 2023. It will begin rolling out the new powertrain on select models beginning this year.
