In terms of an overall package, the GMC Sierra 3500HD has started to show its age. The testers found the Sierra 3500HD to be plenty capable, but some quirks left it in second place. Specifically, the DEF filler location wasn’t appreciated by any, which is under the hood and hard to get to compared to the F-350.
Additionally, judges found the interior quality and infotainment systems to be lacking compared to the F-350 and the segment in general. We assume General Motors knows this and will ultimately remedy the situation with the next-generation pickup trucks. No one was complaining about the extra power from the 6.6-liter L5P Duramax turbodiesel V8 engine, however.
The F-350 simply outdid the GMC 3500HD in numerous facets. It was more comfortable, and more creature comforts and still delivered exceptional performance. For now, the GMC is de-throned, but we have a feeling it’ll be back soon enough.
