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.

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.

The future's electric — but the present is peak gasoline. Burn some rubber! Do donuts!

I vividly remember the year 1993 as a teenager looking forward to getting my driver’s license, longingly staring into Pontiac dealerships at every opportunity for a chance to see the brand-new fourth-generation Firebird and Trans Am. Back then, 275 horsepower, courtesy of GMÂ’s LT1 5.7-liter V8 engine, was breathtaking. A few years later, when Ram Air induction systems freed up enough fresh air to boost power over 300 ponies, I figured we were right back where my fatherÂ’s generation left off when the seminal muscle car era ended around the year 1974. It couldn't get any better than that. I was wrong. Horsepower continued climbing, prices remained within reach of the average new-car buyer looking for cheap performance, and a whole new level of muscular magnitude continued widening eyes of automotive enthusiasts all across the United States. It was all ushered in by cheap gasoline prices. And as much as petrolheads bemoan the coming wave of electric vehicles, perhaps instead now would be a good time for critics to sit back and enjoy the current and likely final wave of internal combustion. Today, itÂ’s easier than ever to park an overpowered rear-wheel-drive super coupe or sedan in your driveway. Your nearest Chevy dealership will happily sell you a Camaro with as much as 650 horsepower. Not enough? Take a gander at the Ford showroom and youÂ’ll find a herd of Mustangs up to 760 ponies. Or if nothing but the most powerful will do, waltz on over to the truly combustion-obsessed sales team of a Dodge dealer and relish in the glory of a 797-hp Charger or 807-hp Challenger. Want some more luxury to go with your overgrown stable of horses? Try Cadillac, where you'll find a 668-horsepower CT5-V Blackwing. You could instead choose to wrap that huffin' and chuggin' V8 in an SUV. Or go really off the rails and buy a Ram TRX or Jeep Wrangler Rubicon 392 and hit the dunes after a quick stop at the drag strip. Go pump some gas. Burn a little rubber. Do donuts! There is nothing but your pocketbook keeping you from buying the V8-powered car of your dreams. Yes, just about every major automaker in the world has halted development of future internal combustion engines in favor of gaining expertise in batteries and electric motors. No, that doesnÂ’t mean that gasoline is going extinct. There are going to be gas stations dotting American cities and highways for the rest of our lifetimes.
