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.

Helicopter crashes on Top Gear Korea set while chasing Corvette ZR1

The formula of Top Gear Korea is seemingly about the same as it is everywhere else in the world, including the flagship British original: involve interesting cars in fantastical situations with charismatic hosts. That prescription has proved to be pretty reliable over the years, and has lead to some truly memorable and exciting pieces of television.
Something like that was undoubtedly what the Korean producers were after when they lined up this segment - a drag race between a Chevrolet Corvette ZR1 and an AH1 Cobra military helicopter. The planners almost certainly did not expect the filming of the segment to go quite as wrong as it actually did, with the helicopter actually crashing into the dirt after the "drag race" had been completed. Thankfully, we're told that no one was seriously injured in the crash, but the footage, in the video below, is pretty damn chilling to watch, nevertheless.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.
