Nissan Reinvents The 4×4 With The E 4orce System

5 min read

The electrification of the automotive sector has opened the door to a notable increase, not only in terms of sustainability, but also in terms of performance, technology and safety . Something that until now was only available to supercars .

In the car , torque delivery is key in any high-performance model . With electrification, anyone who bets on the electric car must know that they have more muscle and more power, but at the same time they demand control. Not everyone is ready to take advantage of this advantage.

This is not the case with Nissan , which in its new proposal represented with the new Nissan Ariya opens a new path towards the future of the crossover segment . Nissan has been working in the electrification environment for many years and the appearance of new models on the market has only accelerated the technological transformation .

His extensive experience in the field of electric vehicles, which began there in 1947 with the Tama , together with his mastery in the world of off-road vehicles (who else would invent the Patrol) , have allowed that with the arrival en masse of the electrification the brand already has advanced solutions in all market segments. And the 4×4 was not going to be an exception .

The Japanese brand has developed a new proposal to understand, take advantage of and propose to users solutions adapted to the electric vehicle, increasing the performance of the off-road vehicles of a lifetime .

Work on the Attesa-e-ts torque-splitting technology in the Nissan GT-R sports car and the experience of the Patrol’s 4×4 intelligent traction system helped fine-tune the arrival of the e-4orce . Nissan will debut with the new Ariya, its flagship for the next few years, this e-4orce technology.

Balance of benefits
With this traction system, it is possible to balance the force of the torque delivery with the needs of the user, adapting each touch of the accelerator and turning it into a dose of adrenaline.

Uncontrolled speed is pointless, and that’s why with the e-4orce , Nissan lets you savor all the power of torque that the electric car has to offer and combine it with safety and traction control . With the e-4orce , the new era of 4x4s begins , and Nissan has arrived to offer it to the world from the first moment.

The name of e-4orce is not accidental. Obviously the ‘e’ responds to electrification and the sound of the word ‘4orce’ is reminiscent of the force of torque delivery. The ‘4’ obviously refers to four-wheel drive.

The torque that is delivered with this technology allows it to be adapted to each of the wheels in an individual and controlled way . This technology manages power and braking, always offering a great feeling of mastery over the torque delivered by an electric vehicle.

The brand presented this system for the first time at CES in Las Vegas and at the 2019 Tokyo show mounted on a Nissan Leaf e +, and it was not until the arrival of the Ariya that it decided to incorporate it as standard. From now on, all Nissan electric vehicles that adopt all-wheel drive will carry the e-4orce name.

Same power delivery
The distribution of power and torque on all four wheels in a differentiated way adds a plus of safety. The e-4orce works as an assistant that allows maintaining the same energy delivery to move the vehicle at all times, making the most of acceleration and deceleration movements to maintain a stable and comfortable driving.

The electrical system assumes the power from the two electric motors , located one on each axis. To date, Nissan electrics only used an engine to provide front-wheel drive, but with the Ariya a new space opens up.

The e-4orce system works by offering control over the chassis, power output and braking, achieving a better feeling for the driver. All the power of the electric motor and its instantaneous torque is distributed according to the needs of each situation.

That allows for balance with the precision of the steering and the line drawn by the vehicle, turning what could be a runaway (electric) horse into a vehicle that is predictable and easy to handle even in sudden reaction situations. The system constantly modulates the power of each double electric motor, as well as the control of the brakes of each wheel , with the aim of generating reliable control for the driver.

Neither understeer nor pitching
In conventional acceleration and cornering , the vehicle has a tendency to project out of the curve (understeer) , which the driver counteracts with increased steering wheel turn and reduced speed. With the e-4orce, torque is intelligently distributed to all four wheels to obtain the most optimal grip at all times .

The system is predetermined to distribute the force 50/50 but depending on the needs , the power can be transferred to the entirety to both the front and rear wheels .

But Nissan’s e-4orce technology doesn’t stop there. It also benefits from regenerative braking, one of the main qualities of the electric vehicle. When decelerating, energy is recovered that is directly sent to the battery. Deceleration force is optimally controlled on each of the four wheels, through a combination of regenerative braking and hydraulic braking, which improves turning and deceleration performance.

Since the system manages the braking and power of each wheel, when regenerative braking is activated on the front and rear electric motors, the system works to reduce the pitch and lean of the vehicle , obtaining greater comfort. Goodbye to nodding and dizziness.

With the e-4orce system, Nissan adds a new pillar to the 100% electric proposal for its new 4x4s . The new era of the sustainable off-roader has arrived and the Nissan Ariya will be the first evangelist .
