At this year's Consumer Electronic's Show, Nissan revealed what the twin-motor electric all-wheel drive system in the Ariya is going to be called, e-4ORCE.

One thing that's very interesting about the system is that its development was apparently helped by the GT-R's ATTESA E-TS all-wheel-drive system that can split torque from 0/100 to 50/50 front-to-rear. It was also helped by the all-wheel drive system in the Nissan Armada.

Automotive News Europe gave a good breakdown on the e-4ORCE system. It apparently will able to be use on SUVs, sedans, and hatchbacks.

The system, dubbed 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 4X4 system, the automaker said.

E-4ORCE can be applied to a range of vehicle types, including SUVs, sedans and hatchbacks.

The first vehicle to feature the system will be the production version of Nissan's Ariya concept. The five-seat electric crossover will have a 300-mile battery range and go from 0 to 60 mph in less than 5 seconds, according to U.S. dealers briefed on the product last summer.
