2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

Performance cars overpower the Detroit Auto Show

At precisely the stroke of noon on Monday, the 2016 Acura NSX rolled on stage at the Detroit Auto Show amid plumes of smoke and dancing lights. The sounds of the powerful engine revving soared to the rafters. It was the second coming of Acura's iconic sports car, and the reveal had all of the expected trappings. Afterwards, champagne corks popped and the bubbly flowed. It was noon in Detroit, but for the green-car movement, it seemed like the clock had struck midnight. That's an exaggeration, but performance was the overwhelming theme of North America's most important show. Ford – which has helped lead the way in smaller displacement engines and early adoption of hybrid powertrains – had more than 1,500 horsepower on stage one point after it revealed the GT concept, the new F-150 Raptor and the Shelby Mustang GT350R. The NSX is technically a hybrid (it has three electric motors), but with 550-plus hp, there's no doubt this Acura was bred on the track. The theme continued throughout the show at nearly every stand. Alfa Romeo showed off the 4C Spider, which is the open-air version of a car that purports to be the spiritual successor of the high-performance 33 Stradale from 1967. On Tuesday, Cadillac is scheduled to reveal the 640-hp CTS-V with the V8 transplanted from the Corvette Z06, and the Lexus was expected to roll out its own V8-powered beast, the 467-hp GS F. For enthusiasts – especially enthusiasts with money – these are halcyon days. But make no mistake, all of this power has a purpose. Ford product chief Raj Nair said the Blue Oval uses high performance cars to develop technologies, like aerodynamics and materials, which are then shared across its lineup. "It's another proof point about how serious we are in developing innovation through performance," he said. Ford, which is rolling out at least 12 performance cars by 2020, said the sporty cars attract younger and more influential buyers to its fold, which can help burnish its image beyond adding sales volume. Toyota is taking a similar approach, senior vice president Bob Carter said, noting the Lexus RC coupe draws people into showrooms and gets them excited about the brand, even if they don't end up buying one. "They provide an aspiration and a halo that provides the attention that gets you noticed in a cluttered market," he said.

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.
