2020 GMC Sierra HD offers loads of tech

The 2020 GMC Sierra HD has finally been revealed, and it's a heck of a lot more subtle than the Silverado HD. Whereas the Chevy went with a wildly exaggerated version of the split grille and headlights the truck is known for, the Sierra simply builds on the 1500 model's design with an expanded grille that doesn't appear to be as tall or wide as the Chevy's. That's not to say it looks unimpressive, though. It's still got a massive fascia, it's just not as extreme as the one with a bowtie on it. With the Sierra's unveiling, we get more details about the powertrains available on the heavy duty GM trucks. The 6.6-liter turbocharged Duramax V8 makes 445 horsepower and 910 pound-feet of torque. That's the exact same output as the engine in the old models. But this time, the engine will be mated to an Allison-branded heavy duty version of the GM 10-speed transmission. A gas engine will also be available, but GMC hasn't revealed details on it yet. The new Sierra boasts a range of new features, some that are unique to it, and some shared with the Silverado. A shared feature is the new steps in the bed sides that are standard on all Sierra HD models. Unique to the brand is the MultiPro tailgate with fancy drop-out step. This tailgate will be available on all trims, and it's standard starting with the mid-level SLT. There are some useful visibility features being shown on the new Sierra, too, such as an available trailer camera system with 15 possible viewpoints, and it can virtually show the rear view on the screen as if there wasn't a trailer in the way. GM's rear-view mirror screen also makes an appearance. An AT4 off-road trim will be available on the new Sierra HD. It has slightly different styling with dark grilles and trim. Off-road upgrades include reworked springs and shocks, skid plates, standard all-terrain tires and a locking rear differential. Pricing has not yet been announced, but the truck goes on sale this summer. Details on prices as well as further specifications will likely be announced near the on-sale date.

GM under fire from safety advocates over braking problem caused by recall fix

Safety experts are lambasting General Motors over what they say is the automaker’s slow notification of owners of certain 2019 sedans and trucks that a recall fix could cause power braking to fail and increase the risk of a crash, the Detroit Free Press reports.  GMÂ’s original recall in December targeted about 550,000 Cadillac CT6 sedans and Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, all from the 2019 model year, over potentially defective electronic stability control and antilock brakes. In that case, GM said the errors would not show up as a diagnostic warning on the instrument cluster. But after GM had done recall work on 162,000 vehicles, about 1,700 owner have complained that their power brakes didnÂ’t work after they had the recall done and then used the OnStar app to start their vehicle. GM then issued a supplemental fix for customers whoÂ’d already had their vehicles serviced. In this case, a diagnostic warning should illuminate saying either “Service Brake Assist” or “Service ECS,” which GM says is a signal that a customer should not drive the vehicle and instead call their dealer, which will tow the vehicle and have it repaired. Safety advocates say the automaker hasnÂ’t gone far enough to protect customers. “The fact that you could potentially start a vehicle and not have brakes is a pretty risky proposition,” Sean Kane, president of the Safety Research and Strategies, which works on auto issues for plaintiffs and governmental organizations, told the Freep. “The fact that they wouldnÂ’t notify owners (sooner) is pretty stunning.” GM told the Freep it was required to notify the National Highway Traffic Safety Administration and file paperwork before it notified customers about the original recall, which was made Dec. 12. It then had to investigate and resolve the problem created by its original recall fix before alerting customers. GMÂ’s call center and dealers are contacting the remaining 900 customers who havenÂ’t yet had the update made to the original recall repair. GM also hired a vendor to send recall letters to the 550,000 customers affected by the original recall notifying them about the update. There are no known injuries or deaths related to the problem.

2019 GMC Sierra spied sporting just a thin wrapping

A new Chevy Silverado is on the way, and along with that comes it's fraternal twin, the GMC Sierra. We've seen spy shots before, but, like the Silverado we saw a few days ago, this is our best look yet. Nearly all of the loose-fitting camouflage has been removed, giving us a decent view of the bodywork. A brief look shows that the Sierra and Silverado will have significant styling differences for this generation. In the past, GMC trucks have been little more than rebadged Chevrolets. That's been changing in recent years, and the divide seems to be growing larger. The grille looks much larger than the Silverado's and there appears to be a small inlet right where the hood meets the front. From the side, we can see that the two trucks have different fenders and beds. The wheel wells on the GMC are squared off at the rear. Compare that to the round wells on the Chevy. Out back, the design is far more similar. Both trucks appear to have rear-facing exhaust outlets. The taillights, too, look to have close to the same shape. A big bulge in the center of the tailgate likely hides a large GMC badge. We still don't have a firm reveal date, but look for some further news this auto show season. Related Video:
