#GMCSierraHD

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.

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.

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.

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.

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.
