2023 J.D. Power Initial Quality Study shows there's less quality than last year

Vehicle inventory, vehicle pricing, and the supply chain are finally showing improvement. Vehicle quality, on the other hand, is still going the wrong way. That's the takeaway from the 2023 J.D. Power Initial Quality Study that found overall problems exceeded last year's record high. The study surveyed owners of 2022-model-year vehicles to assess the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership. 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. For 2022, the average jumped to 180 problems. For 2023, the PP100 is up to an industry average of 192 — an increase of 30 problems per 100 vehicles in just two years. Let's get to the good news first: Dodge reclaimed the crown of having the lowest number of problems per 100 vehicles at 140. Buick won last year with 139 PP100, falling to third this year. Dodge was the first American automaker to top the IQS in 2021. Its return as the least problematic gives parent company Stellantis three wins in four years after Ram was crowned in 2021. It also gives U.S. brands a four-peat after Buick topped the chart in 2022 by having owners report the fewest problems. This year's top 10 is Dodge, Ram, Alfa Romeo, Buick, Chevrolet, GMC, Porsche, Cadillac, Kia, and Lexus. Stellantis gathered a few feathers for its cap, in fact. Maserati showed the largest improvement year-on-year, followed by Alfa Romeo, and Alfa Romeo posted the lowest PP100 among the premium class, beating Porsche and Cadillac. Alfa Romeo has been vocal about working to improve quality, mentioning Lexus as a target. Last year the Japanese brand finished sixth, the Italians finished near the bottom, between Jaguar and Mitsubishi. This year Alfa jumped to third, Lexus dropped to tenth. Ram was the third-best on the list of improvers from 2022 to 2023.   The individual model with the lowest PP100 is the Nissan Maxima. Now for the troublesome bits. In the words of Frank Hanley, senior director of auto benchmarking at J.D. Power, "The industry is at a major crossroad and the path each manufacturer chooses is paramount for its future.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

2015 Chevrolet SS Review [w/video]

The Chevrolet SS is one of the best cars no one's buying. It's a Bowtie-badged version of the Australian Holden Commodore with a 6.2-liter LS3 V8 under the hood. It's got a six-speed manual transmission, General Motors' sophisticated Magnetic Ride Control suspension, and rear-wheel drive. It's a fullsize sedan that comes with every possible amenity you could want. And it's less than $50,000. Chevrolet sold 2,479 SS sedans in 2014. That means it was outsold by every other vehicle the automaker offers, even the police fleet-only Caprice. (I'm only talking about cars that were on sale for the full 2014 calendar year, of course.) The aforementioned manual transmission and MRC suspension were added for 2015, but it's not clear if that's helping. The SS is down 7.7 percent through June of this year, compared to 2014's numbers. But hey, at least it's finally outselling the Caprice. What a damn shame. Granted, GM only planned to sell a few thousand of these each year, but as enthusiasts, this a car we should be gobbling up. It's the closest we'll get to a four-door Corvette, and with the 2015 model year updates, that statement is more true than ever. People often mistook the SS for a Malibu. "Is that a rental car?" Yikes. Aside from the manual gearbox and magnetorheological suspension, the SS is largely unchanged through its year and a half of sales. But that's no bad thing – we were thoroughly impressed with the SS when we first tested it at the end of 2013. Outside, the SS looks the same, which is a bummer. It is not an attractive car, and the chrome brightwork on the side vents and wheels doesn't help. That said, the sedate styling puts it under the radar – more so than competitors like a Dodge Charger 392, anyway. But maybe it's too under the radar. Even in the new, "Some Like It Hot Red" color (yes, really), photographer Drew Phillips reports that people often mistook the SS for a Malibu. "Is that a rental car?" Yikes. Exterior styling is our only gripe with the SS. Moving inside, there's a lot to like. This is easily one of Chevy's nicest, well thought-out interiors (thanks, Holden), with premium materials and tons of equipment. The Chevy MyLink infotainment system carries over, and now features 4G LTE and wifi connectivity. The touchscreen is a bit slow to respond, but otherwise, it's bright, well organized, and packed with functionality. This is easily one of Chevy's nicest, well thought-out interiors.
