The original Super Handling All-Wheel Drive (SH-AWD®) system by Acura has raised the bar on performance, with its ability to direct engine power from the front to rear and side to side. The industry even coined the term “torque vectoring” to describe its unique abilities. The rear electric motors of the hybrid system are a major advancement to this leading-edge handling system.
- When the RLX Sport Hybrid enters a curve, the rear outside motor spins its wheel slightly faster to help rotate the RLX through the turn. In addition, the rear motor on the inside of the curve creates electrically generated drag on its wheel, further contributing to the rotating motion (called “yaw”).
- With the front tires no longer bearing the full load of changing the car’s direction, the sharp turn-in response makes the RLX impressively nimble and responsive, particularly for a car its size.
- Power generated by the rear inside wheel is directed to the rear outside wheel, allowing the handling benefits with little draw from the battery.
- The electrically driven rear wheels automatically perform these actions on a curve and do not require the driver to accelerate through the turn to create the yaw effect.
- The system is just as effective in poor weather, where the power can be directed to tires with more traction and away from those with very little.
