GM doubles miles open to its Super Cruise technology

DETROIT — General Motors said on Wednesday owners of certain vehicles equipped with its Super Cruise assisted driving system will now be able to use it on 400,000 miles (643,740 km) of North American roads, doubling the current operating area as Tesla and other automakers race to deploy hands-free cruising technology. GM's Super Cruise system, like Tesla's Autopilot system, is a driver assistance system, and does not enable true autonomous driving. Spurred by Tesla's aggressive deployment of Autopilot, and Tesla Chief Executive Elon Musk's promises of a more advanced "Full Self Driving" system, GM, Ford, Volkswagen and Mercedes-Benz are racing to deploy competing partial automation technology in major markets. At the same time, safety regulators are showing concern that drivers do not understand that Autopilot and similar systems are not designed to take over driving in every circumstance. The GM system's sensors and software allow a motorist to cruise with hands off the wheel on highways that have been mapped in detail. But the driver is expected to stay alert and ready to take over the car. GM uses technology to monitor the driver, and Super Cruise will sound alarms or slow the car to a stop if it detects that a driver is not responding. Starting later this year, GM plans to enable vehicles equipped with Super Cruise and the company's latest vehicle electronic system to operate hands-free on major, undivided highways in the United States and Canada, as well as additional miles of divided, interstate highways. Currently, Super Cruise operates only on interstate, divided highways. The expansion, enabled by wider digital mapping, will allow owners of properly equipped GM vehicles to cruise hands-free on stretches of Route 66 and the Pacific Coast Highway in the U.S. West or the Trans-Canada highway in Western Canada, GM said. Many of the new roads GM has mapped are in rural, heartland states where GM pickup trucks are popular. GM plans to offer Super Cruise as an option on its Chevrolet Silverado and GMC Sierra large pickups later this year. GM has said previously it intends to offer Super Cruise as an option on 22 models by the end of 2023. Depending on the model, Super Cruise costs $2,200 to $2,500 to add as an option.

2019 GMC Sierra Denali MultiPro tailgate and CarbonPro bed explained

When the 2019 Chevy Silverado debuted at the Detroit Auto Show in January, GM's Mark Reuss promised that the new 2019 GMC Sierra would have some significantly different styling and features than its corporate sibling. Previously, the Sierra has been little more than a Silverado with new front and rear fascias and some extra chrome inside and out. Well, Reuss was right. In addition to new sheetmetal, the Sierra exclusively gets the slick MultiPro tailgate and CarbonPro carbon-fiber bed box The tailgate really is trick. At the debut, GMC had multiple demonstrations, with engineers walking us through all six different configurations. Like all Sierra tailgates, the MultiPro version uses an aluminum skin to reduce weight. It's easy to tell which tailgate is which, as the MultiPro has a distinct cutout in the middle where it can fold down or extend. It can be used to extend the bed, drop to allow easier access, provide a sort of workbench, or be used as a step to help get into the bed. Yes, there's even a handle. Ford who? The step itself can support up to 375 pounds, 75 pounds more than Ford's similar tailgate step. This tailgate really is unique to the Sierra and is standard on SLT and Denali models. That said, the power-operated tailgate from the Silverado won't be coming to the GMC. Chevy gets its own exclusive, too. The Sierra's other big exclusive is the carbon-fiber reinforced plastic bed box. CFRP replaces steel inside the bed though not on the fenders. The bed uses four pieces; one for the bottom, one in the back and two along the sides. This isn't a CFRP. There is no steel hiding underneath these panels. Just take a peek underneath. The bed is a composite that uses 1-inch carbon-fiber threads, not a weave. Sheets of CFRP are molded and quenched — a process where the plastic coagulates and solidifies, locking in the carbon fiber — in just 60 seconds. That allows GMC's supplier to crank out these much more quickly. The finish looks like black fiberglass, though an engineer said that this wasn't the final production version. The final model will have different textures in order to improve grip and keep things from sliding around. GMC is touting the material's dent and corrosion resistance, though it remains to be seen how well it holds up to cracking. A video at the reveal showed people going after it with hammers and cinder blocks, but in-person demonstrations weren't available.

2021 GMC Yukon configurator now open for play-money builds

The 2021 GMC Yukon configurator is open for real and imaginary business. It's missing a number of important options, though, like the AT4 trim and the Premium Capability Package that installs the Air Ride Adaptive Suspension, so the configurator is best suited for practice runs at the moment. Playing our usual game, we started with a livery build in base SLT 2WD trim for an airport shuttle to compare to the livery 2021 Tahoe we built a few days ago. Same as with the Chevy, the GMC offers nine exterior colors. Opposite to the Chevy, the GMC makes you pay for every color except Summit White. Our Onyx Black selection added $195, five colors cost $495, Cayenne Red Tintcoat costs $695, and the super gonzo White Frost Tricoat runs $1,095. We plumped for the SLT Luxury package's driver assistance and convenience features like memory settings for the front passengers, powered seating for the second row, a split third row, the Rear Seat Media Package, and a console lockbox. What began as $59,095 after destination — $4,000 more than the 2021 Tahoe — ended at $64,445, just $2,165 more than our livery Tahoe because the Yukon packages more kit.   The amounts add up a lot quicker at the top end. Our regional rep with a fat bonus check started with a $72,295 Yukon Denali 4WD in the $495 Pearl Beige Metallic with a Teak and Light Shade interior. The $6,500 Denali Premium Package normally costs $500 more, and who can resist a sale? At about 9% of MSRP, it's not a negligible option, but it includes the $1,780 Advanced Technology Package, the $1,500 panoramic sunroof, and a set of 22-inch wheels that are normally $2,995. Since the bonus was big enough to replace the two-year-old jet skis in the garage, our rep added the $465 Max Trailering Package and that automatically appends the ProGrade Trailering features. Put in the Rear Seat Media Package to occupy the kids, locking armrest storage to protect stuff from the kids, and hook up a set of illuminated GMC badges for $535 to wow oncoming vehicles, and the total comes to $83,320. That's more than $10,000 in options without the least effort. However, there aren't any big-money options left to add except a $1,499 rooftop tent.     GM Authority wrote about the package combinations necessary to unlock the Air Ride Adaptive Suspension on the AT4 or Denali trims. Summed up, the check boxes add $3,410 to the price of an AT4, $3,755 to the price of a 2WD Denali, and $6,015 to the price of a 4WD Denali.
