Gas prices are tumbling, truck sales are climbing. Not only are truck sales climbing, but sales of the top trim levels are climbing the quickest. The truck trend is clear by the absolute litany of trim levels all truck makers are adding to their models, including this one. Today in Houston GMC is revealing the Sierra All Terrain X, a new beefed up version of the regular Sierra All Terain.

Before we dive into this, let’s be clear this is not GMC’s answer to the Ford F-150 Raptor. No, we’re still waiting for GM’s answer to that. Instead this is more like GMC’s answer to the Ram Rebel, but even the Rebel may be a stretch. Essentially the All Terrain X is taking the Sierra All Terrain and adding some more exclusive content, such as Goodyear Wrangler DuraTrac MT tires, unique wheels and black sport bar with off-road lights.

The changes aren’t all cosmetic, however. The All Terrain X does add a performance exhaust that gives the Sierra a more aggressive note and gives the 5.3-liter V-8 a 10 horsepower boost to 365 thanks to better exhaust flow. From a functional perspective, the X also adds an inclinometer as part of the driver information center.

Although it’s becoming cumbersome to keep track of all the truck trims in today’s market, this is no surprise. In this case, the All Terrain label has started to become almost another sub-brand of GMC. The Denali label started out in a similar fashion before growing into its own brand, and it won’t be surprising at all if All Terrain ends up similar.

From GMC’s perspective, why not do this? Average transaction prices in half-ton pickups keep climbing and buyers are increasingly in love with the off-road look that the All Terrain X is wearing.

Sierra All Terrain X goes on sale this spring. No word on pricing, but using the regular SLT All Terrain as a base…don’t expect to see the X for anything less than $50,000.
