Mazda Motor Corporation has announced SKYACTIV-VEHICLE DYNAMICS, a series of new-generation vehicle motion control technologies. The first in the series, G-Vectoring Control, will be introduced to all new-generation models starting with the updated Mazda Axela (known as Mazda3 outside Japan), which goes on sale in Japan a few days ago.
Part of the SKYACTIV series, SKYACTIV-VEHICLE DYNAMICS technologies provide integrated control of the engine, transmission, chassis and body to enhance the car’s Jinba-ittai feel—a sense of connectedness between car and driver that distinguishes Mazda vehicles.
The first technology in the SKYACTIV-VEHICLE DYNAMICS series, G-Vectoring Control (GVC) was born of Mazda’s human-centred development philosophy and the novel idea of using the engine to enhance chassis performance. It is the world’s first control system to vary engine torque in response to steering inputs in order to provide integrated control of lateral and longitudinal acceleration forces and optimise the vertical load on each wheel for smooth and efficient vehicle motion.
Optimising the load on each tire brings the movements of the car more in line with the driver’s intentions, reducing the need for steering corrections, including many that are made unconsciously. The outstanding traction the system provides inspires confidence and makes driving more fun. Changes in the acceleration forces acting upon vehicle occupants are smoother, reducing torso sway and making for a more comfortable ride. In addition, GVC significantly improves handling and stability on wet, snowy and unpaved roads.
GVC benefits drivers of all skill levels in a wide range of situations: from low-speed urban commutes to highway driving, winding roads, and even emergency manoeuvres. In addition, it is a highly versatile system adaptable to vehicles of any class and drive type. The only requirements are a SKYACTIV engine, which allows precise control over torque output, and a SKYACTIV chassis, which enables superior dynamic performance.
