GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.

2021 GMC Sierra adds towing tech, new HD Black Diamond Edition

Trailer towing is the focus of several new technologies coming to the 2021 GMC Sierra pickup, with the new features available both on the Sierra 1500 and the Sierra HD. The 2021 Sierra also sees expanded availability of GMC's MultiPro tailgate, a price cut for the available 3.0-liter Duramax turbodiesel six, and a new Black Diamond Edition of the Sierra HD. Pickup truck makers are engaged in a trailering-technology arms race. Already, the GMC Sierra offers its ProGrade Trailering package that features a "Transparent Trailer" virtual camera view and a Rear Trailer View that uses an auxiliary camera mounted on the back of the trailer. To that, GMC is adding a Trailer Length Indicator that can alert drivers of another vehicle in the adjoining lane during a signaled lane-change. A new Jack-Knife Alert warns the driver if the front of the trailer approaches the rear of the tow vehicle. The warning appears in the center screen and can also trigger a seat vibration. The previous Rear Side View split-screen now also works when reversing and adjusts for the angle of the trailer. The Cargo Bed View now includes a zoom feature and hitch guidance for connecting gooseneck trailers. Finally, the previous Rear Trailer View adds a trailer-angle indicator and dynamic guidelines. In other equipment news, the six-position MultiPro tailgate is newly available on the Sierra 1500 SEL and Elevation trims and standard on the Sierra HD SLE. The fancy Sierra HD Denali adds Surround Vision and Bed View cameras to the standard-equipment list. Standard and optional engine choices for the Sierra are unchanged for 2021, but the price of the optional 3.0-liter turbodiesel engine in the Sierra 1500 is reduced by $1,500. For 2021, on models where the 5.3-liter V8 is standard (SLT, AT4, and Denali), the upcharge will be $995. For the SLE and Elevation, where the 2.7-liter V6 is standard, the cost to upgrade to the diesel is now $2,390, again a decrease of $1,500. Lastly, the Sierra HD adds a Denali Black Diamond Edition. It includes 20-inch gloss-black wheels, power-retractable side steps, premium audio by Kicker, an Auxiliary Trailer Camera, trailer tire-pressure monitor sensors, and premium floor mats with removable carpet inserts. It comes in any color you want so long as it's Ebony Twilight Metallic. The Black Diamond Edition is pictured above. Related Video:    

2020 GMC Acadia AT4 Review | A soft-roader in steel-toed boots

For carmakers today, the perfect lineup would be focused almost entirely on trucks and crossovers, favoring profitability at the expense of diversity. Just look at FCA’s Ram and Jeep showrooms. In the General Motors portfolio, that brand is GMC, with not a car to be found in its lineup and several body-on-frame offerings meant to take a serious beating. It should be a license to print money. But a lineup of trucks and SUVs isnÂ’t enough. Some folks want the rough-and-tumble edge of an off-road vehicle, albeit one that can still credibly serve duty in the school pickup line. Enter the AT4 trim level, an off-road package that spans the gap between the GMC's upscale professional image and the off-road oriented buyer. The 2020 GMC Acadia AT4 is the latest member of the family AT4 slots in between the mid-grade SLT and the range-topping Denali, but simply saying itÂ’s the second-most expensive Acadia variant isnÂ’t really doing it justice. If the SLT trim is understated, and the Denali trim opulent, the AT4 trim promises ruggedness and adventure – even if it canÂ’t deliver it.  The Acadia is definitely a soft-roader and AT4 doesnÂ’t do much to change that – itÂ’s effectively an appearance package. It adds a unique grille, 17-inch wheels and AT4 badges — all blacked out — plus a set of Continental TerrainContact A/T tires engineered to offer a comfortable ride while still enabling some off-pavement excursions. There are several unique interior treatments as well, including “AT4” embroidery on the seats, regardless of whether you go with the base upholstery or the upgraded perforated leather ($1,000) that was added to our test vehicle. Note that we didnÂ’t mention anything beyond the small wheels and meaty tires that would actually make the AT4 any better off pavement. ThereÂ’s no extra ground clearance (it remains a meager 7.2 inches), low range 4x4 system or suspension enhancement to be found here. This would be a departure from other GMC AT4 models, including the Sierra 1500 and upcoming 2021 Yukon, which get extra ground clearance, underbody protection and a rugged suspension, but it won't be an outlier. The similarly soft-roading Terrain AT4 has already been announced.  Yet, off-road models tend to get hammered with on-road handling and ride quality criticism and here's where the Acadia AT4 being more of an appearance package pays off.
