Off-Road in HD: GMC Announces the Sierra HD AT4X and Extreme AEV Edition

People use pickup trucks as everyday vehicles, even heavy-duty models, so it’s not surprising to see automakers adding more luxury and capability to their most work-ready models. Rugged, off-road-read heavy-duty trucks are nothing new, but GMC’s taking it to the next level with the new Sierra HD AT4X and Extreme AEV Edition trucks. The pair comes with a slew of upgrades to improve their off-road capability while maintaining the workhorse attitude that people expect from heavy-duty trucks.

Report: More Glitz Inbound to GM's Biggest

All-new for 2020, the heavy-duty versions of Chevrolet’s Silverado and GMC’s Sierra arrived with front-end styling just as controversial as that of their light-duty siblings. Pricier, more potent (in gas V8 form), more capable, and boasting more gears, the new HDs made it easy for buyers to spend ever more bundles of cash outfitting them to just the right spec.

It seems the customization has only just begun.

Open and Shut: NHTSA Issues Hood Recall for New Silverado, Sierra HD

General Motors’ revamped 2020 Chevrolet Silverado and GMC Sierra HD pickups are striking in appearance, but some buyers might be more enamored with the new 6.6-liter gas V8 under the hood. It’s a selling point, but it’s not something you want the truck showing off an inopportune times.

Like, say, when driving down the highway.

The possibility of unexpected underhood peep shows for the occupants of passing school buses are what prompted the National Highway Traffic Safety Administration to issue a recall.

The Grille Next Door: 2020 GMC Sierra Heavy Duty

Fans of heavy duty trucks with grilles the size of Texas have a lot to celebrate this year. Ram dropped its new HD in Detroit and GM previewed its alarmingly styled Heavy Chevy late last year. All signs point to Ford unfurling a new Super Duty very soon, possibly at the Chicago show next month.

Now, GMC’s into the game. The not-a-Chevy brand revealed its 2020 Heavy Duty pickups online last night. The new Sierra HD makes like Daft Punk: harder, better, faster, stronger.

Lawsuit Accuses GM of Using Defeat Devices in Duramax Diesel Pickups

Suing automakers over diesel emissions violations is quickly on its way to becoming passé.

Since Volkswagen admitted to installing software that circumvented pollution laws, regulators have been on the hunt for their next big target. While it might make their efforts seem like a bit of a witch hunt, there’s good reason to be on the lookout. Studies have shown diesel emission levels are often much higher than analysts expected, with experts attributing the results to the high probability that other automakers are skirting regulatory guidelines — likely by way of defeat devices.

Daimler, Renault, and PSA Group are all being investigated in their home countries as FCA faces legal action within the United States.

General Motors is now being sued for allegedly installing defeat devices in its trucks to sidestep emissions tests, making it the sixth major manufacturer accused of diesel cheating since 2015. However, General Motors isn’t dabbling in gray areas, acting confused, or assuring the public it will get to the bottom of the accusations. It says the claims against it are flat out wrong.

  • TheMrFreeze That new Ferrari looks nice but other than that, nothing.And VW having to put an air-cooled Beetle in its display to try and make the ID.Buzz look cool makes this classic VW owner sad 😢
  • Wolfwagen Is it me or have auto shows just turned to meh? To me, there isn't much excitement anymore. it's like we have hit a second malaise era. Every new vehicle is some cookie-cutter CUV. No cutting-edge designs. No talk of any great powertrains, or technological achievements. It's sort of expected with the push to EVs but there is no news on that front either. No new battery tech, no new charging tech. Nothing.
  • CanadaCraig You can just imagine how quickly the tires are going to wear out on a 5,800 lbs AWD 2024 Dodge Charger.
  • Luke42 I tried FSD for a month in December 2022 on my Model Y and wasn’t impressed.The building-blocks were amazing but sum of the all of those amazing parts was about as useful as Honda Sensing in terms of reducing the driver’s workload.I have a list of fixes I need to see in Autopilot before I blow another $200 renting FSD. But I will try it for free for a month.I would love it if FSD v12 lived up to the hype and my mind were changed. But I have no reason to believe I might be wrong at this point, based on the reviews I’ve read so far. [shrug]. I’m sure I’ll have more to say about it once I get to test it.
  • FormerFF We bought three new and one used car last year, so we won't be visiting any showrooms this year unless a meteor hits one of them. Sorry to hear that Mini has terminated the manual transmission, a Mini could be a fun car to drive with a stick.It appears that 2025 is going to see a significant decrease in the number of models that can be had with a stick. The used car we bought is a Mk 7 GTI with a six speed manual, and my younger daughter and I are enjoying it quite a lot. We'll be hanging on to it for many years.
