Nissan, at the 2020 Consumer Electronics Show in Las Vegas, unveiled its new twin-motor all-wheel control powertrain called e-4ORCE. The brand says this technology is able to deliver instant torque to all four wheels in a balanced and predictable fashion.
“The e-4ORCE twin-motor all-wheel control technology offers precise handling and stability, which gives drivers greater confidence and even more excitement than ever before,” said Takao Asami, Nissan’s senior vice president of research and advanced engineering. “This technology enables excellent cornering performance and traction on slippery surfaces and comfortable ride for all passengers.”
e-4ORCE, pronounced e-Force, was developed from the knowledge garnered by Nissan after decades of research and development into something called ATTESA or Advanced Total Traction Engineering System for All-Terrain. Originally engineered for the Nissan Skyline, this system allowed the car to dominate its competition despite having similar power outputs and weighing more.
Thirty years on and the lessons learnt from the development of the Skyline’s torque split system has been applied to develop the e-4ORCE technology. Nissan claims an unparalleled ride comfort as a result of the technology’s ability to minimize vehicle pitch and dive.
Elsewhere, Nissan’s engineers have invented a new light-weight acoustic meta-material which significantly reduces road noise for a quieter driving experience. Nissan will be debuting this sound insulator in the Ariya Concept at CES.
As you may know, electric cars do not produce a lot of noise, therefore making road noise even more distinct. To solve this problem, engineers have developed a special material that’s not only sound absorbent but light-weight as well. Nissan claims it’s a quarter of the weight of heavy rubber padding commonly used in today’s cars.
The lattice-patterned structure is covered with a thin plastic film which bounces sound waves back as it hits the material, this reduces the noise passing through the material and into the cabin.
