Porsche tops J.D. Power quality index as Korean brands soar

While complaints about infotainment systems remain a thorn in the side of automakers for J.D. Power's annual Initial Quality Study, there's a lot to celebrate this year. The average number of problems reported per 100 vehicles fell to 112 in 2015 – a three-percent improvement compared to 116 in 2014. The results of this year's survey are based on the responses of over 84,000 people about problems within the first 90 days of buying or leasing a 2015 model-year vehicle. For the third consecutive year, Porsche tops the rankings with an average of 80 problems per 100 vehicles. Although, that's slightly more than the 74 the German sportscar maker scored in 2014. "While the Japanese automakers continue to make improvements, we're seeing other brands, most notably Korean makes, really accelerating the rate of improvement," Renee Stephens, vice president of US automotive quality at J.D. Power, said in the study's release. In fact, Kia ranks as one of the biggest movers in this year's list. The Korean brand jumped to second place from seventh last year. The company had an average of 86 problems per 100 vehicles, a 20-point improvement. Third place went to Jaguar with an average of 93 problems reported, versus last year's second-place finish with 87 of them. Fourth place was Hyundai, and fifth-place Infiniti also earned a gold star for improvement with 97 issues per 100 vehicles – 31-points better than last year. Fiat still anchored the bottom of the list. However, its 161 problems this year is a lot better than the 206 in 2014. Ranked by nationality, Korean brands (Hyundai and Kia) are now leading the industry in initial quality with an average of 90 problems reported per 100 vehicles. According to J.D. Power, this is the first time Europe's figure beat Japan with 113 and 114 issues, respectively. The American brands also averaged 114. Whereas General Motors dominated last year, the segment awards are spread out in 2015. GM, Hyundai, Nissan, and Volkswagen Group are all tied with four models each earning prizes.

2016 Infiniti QX60 gets a facelift, Hybrid still alive

The future of the Infiniti QX60 Hybrid looked grim a few months ago, when Nissan confirmed the Pathfinder Hybrid was being discontinued. After all, the QX60 and Pathfinder are nearly identical underneath their different bodies. But with this 2016 model year refresh, Infiniti confirms that its QX60 Hybrid will indeed carry on for the new year. It's the same hybrid system as before, combining a supercharged, 2.5-liter inline-four with an electric motor for a combined 250 horsepower and 243 pound-feet of torque. New liquid-filled active engine mounts are added for 2016 in an effort to reduce overall harshness. Non-hybrid models carry on with the naturally aspirated 3.5-liter V6, good for 265 hp and 248 lb-ft. Front-wheel drive is standard with both engines, and all-wheel drive is optional. That's the biggest news for the updated QX60. Everything else baked in to the refresh is pretty standard. Up front, there's a new fascia that better aligns the seven-passenger crossover with every other Infiniti product, and the taillights are slightly more stylized than before. It looks nice, but there's still no hiding those Nissan Pathfinder bones. Infiniti says new shock absorbers and springs will help improve ride quality, and steering effort is improved with a retuned, speed-sensitive electronic power assist system. Standard, Sport, Eco, and Snow modes will help you manage the power depending on the weather and your driving style. We don't know how much this will actually improve the QX60's ride, but we never really had any problems with the luxury crossover's relaxed dynamics, anyway. Look for the QX60 to officially debut at the 2016 Detroit Auto Show, following a reveal at a media event this week. For the full details on all the super-nitty-gritty changes, check out the press blast below. Infiniti QX60 Premium Crossover Offers Enhanced Design, Dynamics, Comfort and Convenience for 2016 - Refreshed exterior design adds to premium look and feel - Chassis dynamics retuned for a more engaging, comfortable drive - Interior revisions bring enhanced luxury for up to seven occupants - Augmented suite of assistive and intuitive technologies NASHVILLE (Dec. 15, 2016) – Infiniti has comprehensively enhanced its versatile QX60 premium crossover for 2016, introducing a wide range of changes that improve the seven-seater's exterior design and its driving dynamics, while showcasing new features and technologies that improve comfort, convenience and safety.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
