GM uses wind power to build SUVs, trucks

This week started with a chill, as the Intergovernmental Panel on Climate Change issued a dire report with scientists warning, "The world we know today is not the world we will see in 50 years," with temperatures rising at their current rates. In the meantime, the trend toward purchasing more SUVs and crossovers continues. Most automakers, though, have set goals toward more sustainable production. That includes General Motors, which, somewhat ironically, plans to use wind power to produce many of its vehicles, including pickups and full-size SUVs. As the Detroit Free Press reports, several wind farms are coming online to support cleaner production as part of a partnership between GM and energy producer CMS Enterprises. At the beginning of October, the 100-megawatt Northwest Ohio Wind Farm began producing energy, supplying GM operations in Ohio and Indiana, where manufactured vehicles include the Chevy Cruze, Chevy Silverado and GMC Sierra. Hilltopper Wind Farm in Illinois will begin producing another 100 megawatts for GM manufacturing in the region. In Texas, where GM builds the Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, GMC Yukon XL and Cadillac Escalade, the automaker is getting 50 megawatts from Cactus Flats Wind Farm beginning October 9. Using wind power isn't just about being green, but also for the sake of price stability. As Rob Threlkeld, GM's global manager of renewable energy told the Free Press, "You don't get the price spikes this way, like you do with fuel, and it reduces the environment footprint of the vehicle you're driving." Threlkeld said that renewable energy has already meant "millions of dollars in savings" for GM. GM plans to power all of its global operations with renewable energy by 2050. This week, the automaker was ranked 76 on the EPA's "National Top 100 List" of green manufacturers. It was the only automotive company listed.

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.

2023 GMC Sierra HD MSRP up at least $1,000

Once Chevrolet bumped up the 2023 Silverado and Silverado HD MSRPs by $1,000, there was no reason to think luxury cousin GMC wouldn't do the same. The proof is here, pricing for the 2023 GMC Sierra HD up on its configurator with premiums of at least $1,000 over 2022 models. As we mentioned of the Silverado, the Sierras have also tracked with the price increases we mentioned in reference to the Chevrolets; the 2022 Sierra 1500 has run up $4,700 over its cost last October, the 2022 Sierra HD is $4,100 more than it was when it hit lots last summer. That puts a 2023 Sierra HD 2500 Regular Cab long bed with two-wheel drive and the 6.6-liter V8 gas engine at a starting price of $42,995 after the $1,795 destination charge, $1,000 beyond the 2022 pickup. At the top, a Crew Cab long bed Denali with four-wheel drive and the 6.6-liter Duramax V8 starts at $83,845, which is $1,250 more than the same rig from the 2022 model year. Moving up a weight class to the Sierra 3500, the price of entry starts $1,000 more than before at $44,195. The big bad boy 3500 Denali 4WD dually starts $1,200 more than before, at $86,245. The situation's a bit cloudier when we step down two classes to the 1500. GM Authority got the price sheet for the 2023 Sierra 1500 and reports that prices are up $1,000 on most trims, but $900 up on the Denali Ultimate and $1,900 up on the AT4. GMC hasn't uploaded the configurator for the 2023 trucks yet, and GMA's price sheet is hard to parse against prices on the 2022 configurator because the end of the model year and supply chain issues have translated into mandatory discounts that can't be accounted for. For instance, the 2022 Sierra 1500 Regular Cab standard box in entry-level Pro trim has an MSRP of $40,000, yet the configurator shows the total vehicle and options price as $39,950. After the $1,795 destination charge, that comes to $41,745. Then there's a mandatory package discount of $1,500, taking the final price before any other fees to $40,245. Meanwhile, GMA's paperwork shows the 2023 price starting at $40,020 after destination, which isn't $1,000 more than any figure on the configurator. At the top end, the 2022 Denali with the Crew Cab, standard box, 4WD, and 6.2-liter V8 comes out to $71,695, only because the front and rear park assist and steering column lock aren't fitted, resulting in a $100 discount.
