Nissan Details e-4ORCE Dual-Motor AWD System Following Tests With Leaf Prototype

Nissan wants to strengthen its position on the EV market with its first e-AWD system called e-4ORCE.

The automaker describes it as a “revolutionary new all-wheel control technology” which assists drivers of all skill levels by providing instant torque to all four wheels and delivering “balanced, predictable power in any situation.”

The “e” in e-4ORCE makes it clear this is a 100% electric motor drive system, courtesy of a twin motor setup. ‘4ORCE (pronounced force) alludes to the vehicle’s physical power and energy, while ‘4’ represents all-wheel control. The technology is in the final development stages and has benefitted from Nissan’s know-how gained from both the GT-R’s ATTESA E-TS torque split system and the Patrol’s intelligent 4×4 system.

Nissan has already built a test car featuring e-4ORCE using a LEAF e+ as a basis. Nissan privately demonstrated e-4ORCE during the 2019 Tokyo Motor Show and at CES in Las Vegas earlier this year. The conclusions drawn after testing are very encouraging, according to the Japanese company.

The automaker lists four ways in which e-4orce technology supports drivers. Firstly, the all-electric system which means e-4orce is built around dual electric motors. Until now, Nissan EVs have all used a single electric motor, typically for front-wheel drive. An AWD system is the next logical step, especially with the future EV crossover heralded by the Ariya Concept.

The system is said to provide instant, smooth acceleration, as well as enhanced control in a wide range of scenarios, including when the driver is required to suddenly react to avoid something in the road, such as an animal or object.

Handling is the second big advantage of e-4ORCE, with Nissan promising “balanced chassis control, line tracing, and steering precision at all times.” This ensures the vehicle’s behavior remains predictable even during sudden maneuvers. To do so, the system constantly modulates the output of each onboard twin electric motor as well as each wheel brake control. By default, the torque distribution is 50/50, but e-4ORCE can also transfer up to 100 percent of power to either the front or rear axles, and a mix in between.

Thirdly, Nissan says e-4ORCE brings reliable comfort for all, which means a smooth ride quality under multiple driving scenarios. The regenerative braking also works to reduce vehicle pitch and dive, helping keep the cabin more level and therefore preventing motion sickness.

Finally, the fourth major advantage is enhanced on-road confidence, including on wet, icy or snowy roads. For example, if the driver applies too much power on slippery roads, the system will manage output to ensure control and traceability is maintained. Nissan did not say if the production Leaf will get the e-4ORCE system as an option.
