Nissan has revealed its new twin-motor all-wheel-control technology, along with new sound insulation material at the CES.
The new twin-motor all-wheel-control technology, dubbed e-4ORCE, provides instant torque to all four wheels. Nissan claims the system is designed “to deliver balanced, predictable power and handling on par with many premium sports cars.”
“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.”
According to Nissan, the tech was derived from lessons learned during the development of the GT-R's ATTESA E-TS torque split system and the Patrol's intelligent 4X4 system.
Engineers developed e-4ORCE to specifically manage electric vehicle power output and braking performance to be smooth and stable.
Nissan says e-4ORCE improves ride comfort due to its ability to minimise vehicle pitch and dive. Engineers have accomplished this by “employing regenerative braking from both front and rear motors, making city stop-and-go traffic less jostling.”
“Similarly, on rough, bumpy roads and when accelerating, motor control is optimized to maintain ride comfort by minimising irregular movement.”
At the CES, the e-4ORCE tech will be displayed on the brand’s Ariya Concept.
Also on display is Nissan’s new lightweight sound insulation material, known as acoustic meta-material, which can help make cabins quieter while also boosting energy efficiency.
The material is made up of a lattice structure and plastic film to limit the transmission of wide frequency band noise in the 500-1200 hertz range.
Nissan says the acoustic meta-material weighs one-fourth of the rubber board currently used to suppress road and wind noise while providing the same degree of sound isolation.
