Tesla Cybertruck Will Have Quad-Motor Option, Rear Steering

The Tesla Cybertruck will now offer a previously undisclosed quad-motor variant, rear steering, and a crabwalk function, CEO Elon Musk revealed on Twitter today. Not only that, the first Cybertrucks produced will be exclusively quad-motor models.

Up until now, the highest-performance Cybertruck was slated to have three motors, a configuration borrowed from the Tesla Model S Plaid. Musk gave no indication as to when this change was made, but we think it’s a response to the high praise Rivian’s quad-motor R1T EV pickup truck has received. Musk specifically called out “independent, ultra fast response torque control of each wheel” as a reason for going quad-motor, which we have specifically praised Rivian for.

We know this is at least a somewhat recent change in plan because we specifically asked about a quad-motor variant when Tesla invited us to a pair of exclusive previews of the Cybertruck in the months before its 2019 debut. At the time, Tesla told us four motors were unnecessary. The Plaid powertrain would make more than enough power and traction management would be handled by a virtual rear differential controlling the two rear motors and brake-based torque vectoring in front. This is the same solution found in the GMC Hummer EV pickup, which is also poised to beat the Cybertruck to market. Other than the Rivian angle, we can’t think of a reason for a late-stage engineering change on this scale.
