BMW, Hyundai score big in JD Power's first Tech Experience Index

While automakers are quick to brag about winning a JD Power Initial Quality Study award, the reality, as we've pointed out before, is that these ratings are somewhat misleading, since IQS doesn't necessarily distinguish genuine quality issues. JD Power's new Tech Experience Index aims to solve that problem. The new metric takes the same 90-day approach as IQS but focuses exclusively on technology – collision protection, comfort and convenience, driving assistance, entertainment and connectivity, navigation, and smartphone mirroring. It splits the industry up into just seven segments, based loosely on size, which is why the Chevrolet Camaro is in the same division (mid-size) as Kia Sorento and the Mercedes-Benz GLE-Class is in the same segment as the Hyundai Genesis (mid-size premium). It makes for some screwy bedfellows, to be sure. Still, splitting tech experience away from initial quality should allow customers to make more informed and intelligent decisions when buying new vehicles. In the inaugural study, respondents listed BMW and Hyundai as the big winners, with two segment awards – the 2 Series for small premium and the 4 Series for compact premium, and the Genesis for mid-size premium and Tucson for small segment. The Chevrolet Camaro (midsize), Kia Forte (compact), and Nissan Maxima (large) scored individual wins. Ford also had a surprising hit with the Lincoln MKC, which ranked third in the compact premium segment behind the 4 Series and Lexus IS. This is a coup for the Blue Oval, whose woeful MyFord Touch systems made the brand a victim of the IQS' flaws in the early 2010s. But Ford and other automakers might not want to celebrate just yet. According to JD Power, there's still a lot of room for improvement – navigation systems were the lowest-rated piece of tech in the study. Instead, customers repeatedly saluted collision-avoidance and safety systems, giving the category the best marks of the study and listing blind-spot monitoring and backup cameras as two must-have features – 96 percent of respondents said they wanted those two systems in their next vehicle. But this isn't really a surprise. Implementation of safety systems from brand to brand is similar, and they don't require any input from users, unlike navigation and infotainment systems which are frustratingly deep.

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.

Cars with the most reckless drivers are full of surprises

Insurify is a site for comparing auto insurance quotes. Because insurance shoppers need to submit information like the vehicles they're driving and the infractions they've compiled while driving those vehicles, Insurify has quite the database of correlations tying certain models to a habit of breaking certain laws. When the site's data analysts decided to compile a list of the top ten models for reckless driving citations in the decade from 2010 to 2019, the ranking contained a few wild entries. The Dodge Challenger making the countdown will surprise precisely zero people. But the Saturn L200? First, a definition: USLegal.com defines reckless driving as "driving with a willful or wanton disregard for safety. It is the operation of an automobile under such circumstances and in such a manner as to show a willful or reckless disregard of consequences." So this list is a caution about particular drivers more than the cars. For a baseline, according to Insurify data, for any random model, 15 out of 10,000 people who drive that model have picked up one citation for reckless driving. Back to that Challenger, then. No shocker for being here, but it's actually number 10, with 44 out of 10,000 Challenger drivers nabbed for a willful disregard of consequences on the road. That's better than the first surprise entry, the Saturn L200, a sedan only on sale for six years, with the least horsepower on the list, and out of production since 2005. The data set put drivers of GM's extraterrestrial sedan at 45 reckless pilots per 10,000 drivers. There are two pickups on the list, the only modern one being the Ram 1500 at eighth, with a rate of 46 in 10,000. Somehow, drivers of the third-best-selling pickup in the U.S. outrun the overwhelming numerical superiority of the best-selling vehicle in the States, the Ford F-150. The other pickup is the Chevrolet K1500 at number five, with a rate of 56 in 10,000. This is not only the oldest vehicle on the list, it went out of production in 2002, before any other vehicle on the list. Between the trucks, the Volkswagen CC slotted in at seven with 47 in 10,000 reckless driving chits, the Cadillac ATS slipped into sixth with 48 in 10,000.  The top four is a bag of unexpected. The Nissan 370Z is the first hardcore sports car on the list at number four, with 61 in 10,000 Z drivers flaunting their Fairladys in the face of Johnny Law.
