Nissan recently introduced the state-of-the-art e-4ORCE technology into the European market, and the technology will debut in the Nissan X-Trail and Ariya compact crossover SUV. e-4ORCE is touted as a new and unique all-wheel-drive system specifically engineered for electric and electrified vehicles to offer confident and reassuring performance in all conditions. Essentially, the system will balance power and braking to offer a smooth, seamless, instantly responsive, and safe drive as power and braking is evenly distributed and balanced.
Nissan’s teams of powertrain engineers combined their expertise on three core elements: electric motor management, all-wheel drive systems, and chassis control technologies to develop a technology that provides reassurance and dynamic poise in everyday scenarios, on or off-road.
The “e” in e-4ORCE stands for Nissan’s 100% electric motor drive system, and “4ORCE” refers to the vehicle’s physical power and energy, with “4” representing all-wheel control. The e-4ORCE all-wheel drive system was developed for use on either Nissan’s pure electric powertrains or with the e-POWER system, and in both, the driven wheels are powered purely by electric motors fed by the battery bank. In the case of the X-Trail, the dual e-motor system has a total output of 157kW (213PS) with a 150kW (204PS) front motor and a rear 100Kw (136PS) motor (PS is the metric measure of horsepower). Together these motors generate acceleration from 0-62mph in seven seconds, and it is claimed that the system has a 10,000 times faster rear torque response than a mechanical 4WD system.
The e-4ORCE system powers a twin motor system evenly distributed on each axle for independent wheel control. Torque is distributed to the front and rear to maximize tire grip according to road surface conditions and the vehicle’s situation, while the braking is individually controlled for each of the four wheels. With the e-4ORCE system engaged, steering will smoothly follow the intended cornering line with minimal correction while the technology provides continuous balanced chassis control, line tracing, and steering precision to anticipate the driver’s behavior and compensate for common responses such as understeering, ensuring that the cabin remains level at all times.
Due to the twin-motor system’s precise control and the brake torque-vectoring capabilities, the vehicle maintains the right course whether the road is wet, oily, slippery, or covered in snow. The key to the vehicle’s on-road poise is the balanced distribution of power from the twin motor system, which can be adjusted in 1/10,000th of a second, considerably faster than traditional mechanical all-wheel drive systems. These figures are mind-boggling!
According to Nissan, an additional benefit of e-4ORCE for passengers is the comfortable drive with minimal body longitudinal “dive” under deceleration thanks to strong regenerative braking while pitch is suppressed by controlling the regenerative balance between the front and rear axles. The twin motor system means a greater level of regenerative energy capture than a single motor system, consistently optimizing the vehicle’s efficiency.
Cliodhna Lyons, Vice President of Product Planning Nissan AMIEO mentions that,
“e-4ORCE is the latest of many forward-thinking technologies developed by Nissan over the years. We can’t wait for our customers to experience this innovative system on models like the Ariya e-4ORCE and the new Nissan X-Trail. We’re sure our customers will enjoy a noticeable difference in their driving experience.”
