The tweet represents the first official mention of a quad-motor Cybertruck. Since the EV was unveiled in the fall of 2019, Musk and Tesla have said the tri-motor variant would be the most powerful variant. Although no horsepower or torque figures have ever been revealed, the automaker has promised its top-tier pickup would be able to zoom from zero to 60 in less than three seconds, tow up to 14,000 pounds and travel 500 miles on a single charge. One can only assume that a Cybertruck with an extra motor would be faster and more powerful, though its range might take a hit.

We know that the four-motor variant will arrive first and sit atop the Cybertruck lineup, but we don’t know if it will replace one of the previously announced models. It’s possible that the newly announced version could take the place of either the single-or tri-motor model.

We do know that having a motor situated on each wheel will give the EV at least two new features. In a follow-up tweet, Musk wrote that the quad-motor pickup will also have front and rear wheel steering, which would likely allow it to perform tank turns. It will also be able to drive diagonally “like a crab,” according to Musk. Notably, the GMC Hummer EV, a direct competitor to the Cybertruck, also has a driving mode called “Crab Walk.”
