An all-wheel drive (AWD) system that can independently distribute torque to each wheel? That’s not exactly a new thing, as brands like Mazda, Subaru, Nissan, Ford, among others, have already developed such driving mechanism and incorporated them with their cars. However, Toyota Motor Corporation has included something in its latest Toyota New Global Architecture (TNGA) platform that will allegedly boost the car’s fuel efficiency and minimize energy loss.
Dubbed as the Dynamic Torque Vectoring AWD system, this new system from Toyota automatically sends torque to either left or right wheels as the situation needed - just like other intelligent AWD systems do.
In case you haven’t heard, this system improves the vehicle’s handling and stability, which translates to increased safety.
Here’s how the system works:
What Toyota has, however, are the world’s first ratchet-type dog clutches that stop the drive system rotations independently, transmitting the power to the rear wheels automatically. In simplest terms, it won’t engage AWD when not needed, therefore, it’s projected to reduce fuel consumption and energy loss in the process.
Dog clutches are designed not to slip, which means they will either disengage or engage the system. With both front and rear wheel shafts having the clutches, the system is said to be more efficient than other intelligent AWD system types.
The Dynamic Torque Vectoring AWD system is bound for gasoline-powered Toyotas, with 3 new models and 8 variations on the line. This also includes a new E-Four system for hybrid vehicles, which has an increased 30% torque to the electrically-driven rear wheels for better handling.
Now, which Toyota cars will first get this new drivetrain system? I’m betting my money on the RAV4 or C-HR crossovers.
