Nissan unveils all-new twin-motor, electric AWD system.
Nissan revealed a new twin-motor, all-electric, all-wheel-drive system at the CES expo in Las Vegas. The technology is expected to debut in Nissan's first electric crossover Ariya, which could arrive in showrooms already in 2021.The system, named e-4ORCE, delivers high-torque, precision handling and stability, Nissan said. It achieves this by optimizing power delivery to each of the four wheels.
Power flow to the front and rear motors can be independently controlled, while torque to the left and right wheels can be further modulated through coordinated braking.The e-4ORCE technology offers precise handling, cornering performance and traction on slippery surfaces, Takao Asami, Nissan's senior vice president of research and advanced engineering, said in a statement.
Beyond spirited acceleration and sure-grip handling on slippery surfaces such as snow and wet pavement, dual-motor control also makes for smoother deceleration.Regenerative braking from both front and rear motors makes stop-and-go city traffic less jarring to passengers. Similarly, the granular motor control delivers a smoother ride on bumpy roads.The two-motor technology is based on lessons learned during the development of the Nissan GT-R's ATTESA E-TS torque-split system and the Nissan Patrol's intelligent 4X4i system, the automaker said.
