GMC Hummer EV range is 329 miles; deliveries in December

It'll be a very Hummer Christmas for some households, as General Motors says it will begin deliveries of the electric GMC Hummer pickup in December, according to GMC boss Duncan Aldred. And we now know the truck's EPA range number: 329 miles on a charge. GM had previously predicted the Hummer would achieve a range of 350 miles.  That 329-mile figure applies to the Hummer Edition 1, the top-of-the-line, $100,000-plus iteration that will be the first trucks off the line. The Edition 1 will also tow up to 7,500 pounds and carry up to 1,300 pounds. Aldred told reporters on a conference call that subsequent, less-pricey models will achieve longer ranges and will be along in 2023.

Aldred said almost half of the 125,000 people who have expressed interest in the Hummer have put down $100 to reserve one. GM has said the first year of Hummer production is sold out. The Hummer EV joins the Rivian R1T as the first electric pickups to market. Ford's F-150 Lightning rolls out in 2022, and other electrics from Detroit and startups are expected to roll out after that. Tesla is building a $1 billion facility in Austin, Texas, that will, among other things, build the Cybertruck, though timelines on that have come and gone. The Hummer, by contrast, was developed in just 18 months. It made a big splash last week when President Biden took the wheel during a tour of GM's Factory Zero assembly plant in Hamtramck, Mich. Biden gleefully demonstrated the acceleration of the four-ton, 1,000-horsepower truck, which is said to do 0-to-60 in 3.1 seconds. He then declared, "This sucker's something else." Next up for GM's EV push will be the Cadillac Lyriq SUV in 2022. The electric Chevy Silverado and GMC Sierra pickups will be revealed Jan. 5. And the SUV version of the Hummer will be introduced in 2023. Aldred expects the SUV to ultimately make up the majority of Hummer sales. Related video: This content is hosted by a third party.

2020 GMC Acadia refresh brings a new engine, AT4 trim level

It's mid-cycle refresh time for the GMC Acadia, and the updated 2020 model kicks off its changes with a new face. It has a square-jawed grille seemingly pulled straight off the Sierra full-size pickup, and the size is amplified by the slender new LED headlights on either side. At the rear, the LED taillights are taller and more chiseled. A new AT4 trim level adds more visual distinction with black trim and wheels, plus all-terrain tires to make it a little more capable off road. The AT4 also boasts standard all-wheel drive. Under the revised skin, the Acadia hides one of two carryover engines, or a new turbocharged 2.0-liter inline-4. This new engine makes 230 horsepower and 258 pound-feet of torque with the help of a twin-scroll turbocharger. To make it more frugal, it's able to deactivate two of its four cylinders. The turbo engine is standard issue on the SLT and Denali trim levels. The carryover engines include a naturally aspirated 2.5-liter 4-cylinder making 193 horsepower and 188 pound-feet of torque, and a naturally aspirated 3.6-liter V6 making 310 horsepower and 271 pound-feet of torque. The V6 is standard equipment on the AT4 trim. No matter the engine, all 2020 Acadias get a 9-speed automatic transmission. The new transmission also ditches the current Acadia's mechanical shift lever in favor of an electronic shifter with the Terrain's mix of buttons and triggers. It does free up space between the seats, but the button arrangement is still as strange as it was when we first saw it in the smaller crossover. There are a handful of other little upgrades to mention. The suspension has been revised for greater comfort; the infotainment has been revised with a bigger screen, USB-C inputs and customizable profiles; and wireless phone charging is now an option. The updated Acadia goes on sale this fall, and pricing will probably be announced close to launch.

2019 GMC Sierra carbon fiber bed: How it's made

FORT WAYNE, Ind. — The redesigned 2019 GMC Sierra has some pretty nifty features, and the one that has had the most attention is the MultiPro flipping and folding tailgate. But the Sierra also features the first-of-its-kind carbon fiber truck bed. It's interesting, of course, for its capabilities, such as being 62 pounds lighter than the all-steel box. It even adds more cargo volume since the material can be assembled and shaped differently from steel. As it turns out, the assembly process is cool, too, which we learned when GMC invited us to see the beds being made. Every GMC carbon fiber bed starts out as perfectly flat sheets of thermoplastic carbon fiber. The sheets consist of a mix of fibers and resins, a bit like the molded carbon fiber parts Lamborghini uses. The sheets are manufactured by Japanese company Teijin, which collaborated with GMC to develop the bed. They're all delivered to Continental Structural Plastics (CSP) in Fort Wayne, Ind., for construction into the actual bed. The company, a subsidiary of Teijin, makes a wide variety of composite and plastic parts for the car industry, including body panels for the C7 Chevy Corvette. The rectangular sheets are cut to shape and stacked up at a giant stamping press. Robots pick up sheets and slide them onto a conveyor that goes into a large oven. The heat softens the parts so they can be stamped. The large primary bed parts such as the base are stamped by CSP's enormous 3,600-ton press, and the smaller ones go through a 1,000-ton press. Each press can do different parts using different stamping dies, and CSP switches between dies to produce different batches of parts. After stamping, the parts roll out mostly ready for assembly, but there are rough edges that are trimmed off by water-jet cutters. These cutting machines also create holes for fasteners and for parts such as tie-down hooks and lights. The stamping process also provides the carbon fiber bed with a unique Easter egg. On the bottom of the base of the bed, there are two words: "Connors Way." This is a tribute to Tim Connors, who was the chief engineer of manufacturing at GM and a strong proponent of the carbon fiber bed. He was tragically killed in a motorcycle crash a few years ago. The words were added to honor him, and they were fortunately approved for production. There are some components to the bed that aren't stamped from the flat sheets of material.
