GM takes 2020 full-size pickup sales crown

It's no secret that 2020 was an unconventional year for auto sales. Extenuating circumstances or not, it was a year of upheaval even for ever-resilient (and ever-profitable) pickups, with General Motors taking the crown from Ford in the full-size segment.  The Ford F-Series still outsold every other full-size pickup nameplate in the country by a significant margin. It's only when you combine GM's Chevrolet Silverado and GMC Sierra variants that you get a number that exceeds Ford's. This isn't really a new phenomenon, either. In fact, it was only somewhat recently that Ford took the overall full-size crown away from GM, and not only did Ford widen the gap in recent years, but Ram has once again become a legitimate challenger, even managing to outsell the Silverado by a healthy margin in 2019, but never coming close to the F-Series in terms of total volume.  But, 2020 being 2020, things got weird yet again. Ram remains relevant, of course, but Ford got caught with its pants down thanks to the one-two punch of COVID and the generational changeover of the core F-150 model, which resulted in a production interruption as the company's assembly facilities transitioned from building the old 2020 model to the new-for-2021. This perfect storm, as it turns out, was sufficient for GM to walk away with the full-size crown. See for yourself: Full-size 2020 pickup sales: GM total: 847,110 F-Series: 787,422 Silverado: 594,094 Ram: 563,676 Sierra: 253,016 Tundra: 109,203 Titan: 26,439 As you can see, Ram slipped back behind Silverado, slotting comfortably into third place. The Silverado 1500 had a flat year, but the heavy- and medium-duty variants bucked the trend and contributed to a slight uptick in sales for the nameplate, while F-Series tumbled more than 12% (nearly 110,000 units), opening the door for GM to steam ahead.  There were similarly significant shakeups in the midsize truck segment. First, 2020 was the first full year of retail sales for the Gladiator pickup, which surged to fourth place behind the stalwart Tacoma, Ranger and Colorado. GM's combined sales of the Colorado and Canyon are good enough for second place by manufacturer, but nowhere close to what it would take to dethrone Toyota.

GM being sued over imploding Bosch fuel pumps in Duramax diesel trucks

Texas-based law firm Hilliard Martinez Gonzalez (HMG) this week filed a class-action lawsuit against General Motors over an alleged issue with Bosch CP4 fuel pumps. The suit claims Bosch designed the CP4 pump to work with European diesel fuel, which is thicker than U.S. diesel. When GM installed that pump in the 6.6-liter Duramax engine used from the 2011 to 2016 model years, the lawsuit claims the thinner U.S. fuel didn't provide enough lubrication, allowing air pockets to form in the fuel pump. That, in turn, allegedly let metal rub against metal inside the pump, causing the pump to eventually disintegrate and "send thousands of metal shards into the fuel injection system and every part of the engine." The Detroit News reported on the most recent lawsuit filed in Michigan's Eastern District Court, but the case is another piece of nationwide legal maneuvering going on since at least last September. Every U.S. truck maker used the Bosch CP4 fuel pump, and HMG originally went after all of them, as well as Bosch. On September 30, 2018, HMG filed a class-action suit in Texas on behalf of eight plaintiffs. The law firm wanted to prosecute the affair under RICO — the Racketeer Influenced and Corrupt Organizations Act — and named 10 defendants: FCA US LLC, FCA North America Holdings, LLC, F/K/A Chrysler Group, Fiat Chrysler Automobiles, N.V., Ford Motor Company, General Motors LLC, Robert Bosch GmbH, Robert Bosch LLC, VM North America, Inc., and VM Motori S.P.A.  The firm filed another suit in Florida on Nov. 2, 2018, against the same 10 defendants, again under the RICO statute, this time on behalf of more than 30 plaintiffs. We don't know how many other suits might have been filed, but the two suits mentioned apparently didn't have legs — the courts dismissed both quickly. So HMG shifted its strategy away from the RICO angle, and focused its efforts on GM, filing suit in California on Nov. 20, 2018. Instead of trying to catch 10 fish with a small net, HMG wants to score one fish with a big net. The results have borne more promise for the plaintiffs. In July this year, a judge in California denied GM's motion to dismiss, noting "the alleged defect is central to the vehicleÂ’s function." This latest suit filed on Aug. 6 in Detroit singles out GM again.  The Bosch CP4 is known to be problematic, however.

Which is more fuel efficient, driving with a pickup's tailgate up or down?

Thanks to the smoke wand in the wind tunnel, you can actually see the difference in our video.
Should you drive with your pickup truck's tailgate up or down? It's an age-old controversy that's divided drivers for decades. Traditionalists will swear you should leave the tailgate down. Makes sense, right? It would seem to let the air flow more cleanly over the body and through the bed. But there's also a school of thought that argues trucks are designed to look and operate in a specific manner, and modern design techniques can help channel the airflow properly. So don't mess with all of that: Leave the tailgate up.
