General Motors recently re-filed for trademarks that we’ve seen in the past, both of which point to high-performance Chevrolet Silverado variants. The first trademark is “ZRX”, while the other is “ZH2.” Both trademarks were filed on February 17, 2023, and both are intended for “motor land vehicles, namely, automobiles.” For most people, “ZH2” and “ZRX” appear to be nothing but jumbled letters and numbers. But for Chevy truck fans, these designations not only ring a bell, but also spark a flame of curiosity.

ZRX Trademark: Likely Bound For Chevrolet Silverado And Colorado ZR2 Race Trucks
At first, speculation was that the top-end Chevrolet Silverado that we know today as the ZR2 would have the “ZRX” designation. We also heard the rumors of a dedicated Ram TRX and F-150 Raptor fighter from Chevrolet that would take the form of a supercharged Silverado, but those rumors continue to hold zero substance to this day.
That “Meteor” Silverado you may have heard of? Fake news!
So, what could the “ZRX” trademark from General Motors actually elude to? Our best guess is this: a turnkey race truck from Chevrolet. We heard from the truck marketing director directly that the company is strongly “interested” in selling off-road race trucks based on the Chevrolet Colorado ZR2 for privateers to compete in events like the Mint 400, Vegas-to-Reno, and the Baja 1000. That may also end up including the Chevrolet Silverado ZR2, as well. Currently, Chad Hall Racing fields both a new Colorado ZR2 and Silverado ZR2 in the Best In The Desert Series, where both race trucks took home championship titles in 2021.


GM ZH2 Trademark: Hydrogen-Powered Chevrolet Silverado And Colorado Coming?
As for the “ZH2” trademark. At the moment, the designation has only been found on one truck: the Chevrolet Silverado ZH2 Concept – a hydrogen fuel-cell powered pickup truck for GM Defense. Before that, there was the Colorado ZH2 Concept in 2016. This, too, was a hydrogen fuel cell off-road military truck. More than that, this Halo Warthog looking type of machine ran and drove as it should, and some media even got to experience it firsthand, while the Department of Defense evaluated the truck, as well.
Both the Chevrolet Silverado ZH2 and Colorado ZH2 suggest that GM is once again looking to dabble in off-road performance powered by hydrogen in some capacity. This of course could mean another concept truck soon, or it could mean something more. It could mean a dedicated effort from General Motors to build and sell a hydrogen-powered vehicle, likely using the Chevrolet Silverado (and/or GMC Sierra) as starting point.
