In the world of pickups, GMC has introduced the Sierra All Terrain X, a brawnier version of their upmarket full-sized truck. This Sierra has a capable off-road suspension and a locking rear differential. The engine gets a ten horsepower boost bringing it up to 365 from its 5.3 liter V8 thanks to a freer-flowing exhaust. Although this truck will leave you grinning after a long day of mudding, we don’t think the fellows at Ford are considering this a Raptor competitor, but if you want a comfy truck you can run through the rough stuff, the All-Terrain X might be the Sierra for you.
