GMC will offer a four-wheel steering system on its upcoming Hummer electric vehicle.
Dubbed “Crab Mode,” the system is designed to enhance low-speed maneuvers and avoid obstacles along tight off-road passages.
For now, GMC describes the technology this way: "Real revolutionaries forge their own direction."
The technology is similar but different than the “tank turn” system that Rivan plans to introduce next year on its R1T pickup and R1S SUV.
Employing the truck’s four electric motors, Rivian’s system will be able to turn the trucks on their axis by powering the wheels on one side of the vehicle forward and those on the other side in reverse, similar to the capability of a military tank’s tracks.
GMC says its system will allow the Hummer to travel in a diagonal direction.
GMC will reveal more about its Crab Mode system and other features when the company unveils the Hummer pickup on Oct. 20. Production of the 1,000-hp model is due to start a year later at GM's Detroit-Hamtramck factory, which is being refurbished exclusively for EVs.
A Hummer SUV also is in the works.
A young(ish) guy that I’ve known for a number of years, a man who spent the better part of his career writing for auto buff books and who is a car racer on the side, mentioned to me that his wife has a used Lexus ES Hybrid.
Lithium-ion batteries have become the technology of choice for EVs, and falling costs and rising energy levels could keep them on top for nearly two decades.
