Sunday Drive: Trucks and SUVs of all shapes and sizes

The American automotive marketplace is dominated by trucks and SUVs, and so was the last week of coverage on Autoblog. By far, the most popular story of the week was our First Drive of the 2018 Lincoln Navigator. It may look like an old-school lumberer, but in reality Lincoln's flagship is a thoroughly modern, turbocharged-V6-powered, three-row, luxury people mover. The Jeep Wrangler is the world's most recognizable vehicle. So it's no surprise that the next version looks a whole heck of a lot like the last one, and the one before. It's all in the details, which is why we were so excited when Jeep decided to unleash a trio of images showing both two- and four-door Wranglers for us to dissect ahead of the SUV's official debut at the L.A. Auto Show later this year. Past that, spy photos of the next Chevy Silverado and Ram 1500 were predictably popular. See both of those below, and the cap it all off, check out the entire week's worth of SEMA coverage – including the bonkers Hennessey VelociRaptor 6x6 – in our mega image gallery at the bottom of this post. Enjoy! As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2018 Lincoln Navigator First Drive | From black sheep to flagship 2018 Jeep Wrangler revealed: First photos released before L.A.

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.

Buick takes top spot in 2022 J.D. Power Initial Quality Study

People, economies, and supply chains weren't the only things continuing to get sick over the past year. The 2022 J.D. Power Initial Quality Study (IQS) is out, showing the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership increased overall. The average figure for the 32 ranked manufacturers in 2020 was about 166 problems per 100 vehicles. In the 2021 IQS, that dropped to an average of 162. This year, the average jumps to 180 problems. J.D. Power says that figure is a record high over the 36-year history of the study. Buick leapt to the top of the rankings this year with the fewest issues, at 139 problems per 100 vehicles in the first 100 days of ownership. After Dodge became the first American automaker to lead the IQS in 2020, followed by Ram in 2021, this year marks a three-peat for U.S. carmakers. Dodge took second this year at 143 PP100, Chevrolet third with 147 PP100, Genesis the first luxury maker on the chart in fourth with 156 PP100. Between February and May, this year's study gathered responses to 223 questions from more than 84,000 new 2022-model-year car owners and lessees. The questions are designed to zero in on real-world problems new owners encounter with nine categories of vehicle features: Infotainment; features, controls and displays; exterior; driving assistance; interior; powertrain; seats; driving experience; and climate. As has been the case in the past few year, infotainment has proved to be the most problematic bugbear making scores worse. Considering features individually, six of 10 of the worst problem areas dealt with infotainment, causing infotainment's score of 45 PP100 to be 19.5 PP100 worse than the second-placed feature. Consumers ranked getting Android Auto and Apple CarPlay to connect reliably as the most troublesome.  GM didn't just score with Buick, which was one of only nine of the 33 ranked brands to show improvement this year. The conglomerate earned first place with the fewest PP100 among all the automaker groups, and scored the most model-level awards with nine, ahead of BMW with eight and Hyundai Group with three.  This year's study again showed a gap between luxury and mass-market makers, thought to be down to the amount of tech in luxury vehicles that consumers aren't properly informed about or that doesn't act as expected — that latter issue exacerbated by the chip shortage.
