JAKARTA - General Motors (GM) does not want to lose in future electric vehicle competition. Recently, a company based in Detroit, United States (US) filed a powertrain patent for the next generation EV.

Based on the GM Authority report, Friday, January 3, the patent shows an electric drive with a connection that can lock it up to produce higher torques. This model can work on the front and rear doubles to allow it to appear in the quad configuration of a motorcycle or four electric motors.

In the patent, it also has a mechanical locking mechanism through a kind of coupling package that is useful for performance on highways and off-road capabilities.

The directional stability can be improved on acceleration on the straight, which can result in an increase in performance of 0-60, and at high speeds, which can reduce excessive steering sensitivity, the company said in the patent.

In other words, this lockdown system will not make EVs faster, but will make high-performance EVs more agile and controlled at high speed.

In off-road application, this system can detect the occurrence of wheel slips or one wheel off the ground and channel the combined torque from two motorbikes to one wheel.

Of course, this application is very suitable for use in offroad-oriented models based on GMs such as the GMC Hummer EV and is likely to be used in the electric version of Chevrolet ZR2 or GMC AT4X.

If the patent manages to penetrate the market, then this will be the first quad electric motor powertrain presented by GM. Currently, the company that houses the Cadillac, Chevrolet, GMC, and Buick brands has designed a configuration of three electric motors on the Hummer EV to produce 1,000 dk of power.

Although the model that will carry this configuration is still a mystery, it is possible that the quad-motor will be used in the Corvette crossover version in the future. In addition, it is hoped that these drivers will also be present in the crossover or Cadillac sedan models in the next few years.
