If you thought Mazda hadn’t began its EV development, think again. In the 2019 Mazda3 AWD launching, two engineers from Japan, including the creator of Mazda’s G-Vectoring Control Plus (GVC+) vehicle dynamics control attribute, revealed that the company is currently testing the system in electric vehicles. Development of GVC+ took almost a decade and we now understand why; it was future-proofed to be used in conventional gas vehicles, hybrids, and EVs. Integrating GVC+ into EVs is a no-brainer since it’s a lot easier to calibrate electrical motors and they react faster, allowing for greater control of vehicle behavior.
As part of its Sustainable Zoom-Zoom 2030 plan, Mazda will collaborate with Toyota and Denso in developing EVs, investing 5 percent in a joint venture. The partnership includes developing powertrains and platforms for their EVs. The rotary engine will return as a generator in EV software, and is expected to arrive sometime in 2020.
In its current application, GVC+ varies engine torque to transport weight for superior turn-in. The brakes are also utilized to enhance cornering and overall vehicle handling and stability. On the 2019 Mazda3, GVC+ works with the all-wheel-drive system to deliver power to where it’s needed and keep the car from becoming unwieldy in poor road conditions. The driver also makes less steering inputs cars equipped with GVC+ since the system is able to boost turn-in and allow it to rotate better through corners, particularly when equipped with all-wheel drive.
For EVs, GVC+ will likely be used to control vehicle behavior using electric motors and brakes, overdriving or slowing down the wheels as necessary. Among the engineers mentioned that the system allows for “seamless torque controller ” in EVs, which should enable the car to put power down better. Other automakers, Tesla included, are already using similar tactics with electric motors, as we observed in the Model 3 Performance with monitor mode, which may tweak power output to the rear wheels to enable the car to rotate better.
Mazda hasn’t said when its electrified models will arrive in the U.S., but expect all of these to feature GVC+. In the current lineup, the MX-5 Miata is the only version without it; the CX-3, CX-9, and Mazda6 use G-Vectoring Control (GVC) while the 2019 Mazda3 and CX-5 use GVC+, which adds the braking aspect for improved cornering, torque vectoring, and greater stability. Expect GVC+ in future vehicles such as the upcoming CX-30 that recently surfaced in the 2019 Geneva motor show.
With GVC+ playing an integral role in keeping Mazda vehicles fun-to-drive regardless of what’s powering them, we expect the system to continue evolving. GVC+ previews the future of Mazda’s drivetrain technology; its capabilities in gas-and diesel-powered vehicles are just a sampling of what it can do when you bring electric motors, regenerative braking, and instant power delivery into the mix.
