What do J.D. Power's quality ratings really measure?

Check these recently released J.D. Power Initial Quality Study (IQS) results. Do they raise any questions in your mind? Premium sports-car maker Porsche sits in first place for the third straight year, so are Porsches really the best-built cars in the U.S. market? Korean brands Kia and Hyundai are second and fourth, so are Korean vehicles suddenly better than their US, European, and Japanese competitors? Are workaday Chevrolets (seventh place) better than premium Buicks (11th), and Buicks better than luxury Cadillacs (21st), even though all are assembled in General Motors plants with the same processes and many shared parts? Are Japanese Acuras (26th) worse than German Volkswagens (24th)? And is "quality" really what it used to be (and what most perceive it to be), a measure of build excellence? Or has it evolved into much more a measure of likeability and ease of use? To properly analyze these widely watched results, we must first understand what IQS actually studies, and what the numerical scores really mean. First, as its name indicates, it's all about "initial" quality, measured by problems reported by new-vehicle owners in their first 90 days of ownership. If something breaks or falls off four months in, it doesn't count here. Second, the scores are problems per 100 vehicles, or PP100. So Power's 2015 IQS industry average of 112 PP100 translates to just 1.12 reported problems per vehicle. Third, no attempt is made to differentiate BIG problems from minor ones. Thus a transmission or engine failure counts the same as a squeaky glove box door, tricky phone pairing, inconsistent voice recognition, or anything else that annoys the owner. Traditionally, a high-quality vehicle is one that is well-bolted together. It doesn't leak, squeak, rattle, shed parts, show gaps between panels, or break down and leave you stranded. By this standard, there are very few poor-quality new vehicles in today's U.S. market. But what "quality" should not mean, is subjective likeability: ease of operation of the radio, climate controls, or seat adjusters, phone pairing, music downloading, sizes of touch pads on an infotainment screen, quickness of system response, or accuracy of voice-recognition. These are ergonomic "human factors" issues, not "quality" problems. Yet these kinds of pleasability issues are now dominating today's JDP "quality" ratings.

'Latest production version' of Porsche 918 shown off on Twitter

Porsche posted a picture of what it is calling "the latest production version" of the 2015 Porsche 918 Spyder on Twitter. It looks like the gasoline-hybrid supercar is being driven sportively on some California back roads during Monterey Speed Week.
Whatever updates were made to this version aren't visual (except for the paint), as the one Chris Harris drove last spring and another seen hot-weather testing in Nevada both had production bodies. We presume the changes are relatively minor and more than skin deep - perhaps brake calibration, suspension tuning or tweaks to the powertrain - but Porsche didn't release any more information.
The 918 Spyder is Porsche's latest supercar, which will compete with the LaFerrari and the McLaren P1 hybrid supercars. The Porsche may be the underdog of the group when considering horsepower, acceleration, top speed and price, but the 887-horsepower brute has the most advanced hybrid drivetrain of the three.

Porsche announces Cayman GT4 with 911 GT3 components

For years, there's been a debate among Porsche fans about which of its products is a better sports car, the 911 or the Cayman. It would only take a few sentences before those in the Cayman corner said that Porsche wouldn't make the Cayman as good as it could be for fear of overshadowing The Number One Son. We have a feeling these conversations are going to get a lot livelier with the introduction of the Cayman GT4, which pilfers lightly from the 911 Carrera S and heavily from the 911 GT3. On the outside, you can look to its front fascia, wheels, and fixed rear wing, and 30-millimmeter lower ride height for GT3 inspirations. Underneath, there's a 385-horsepower, 3.8-liter flat-six engine amidships, credited as being derived from the Carrera S. While there are those out there still lamenting the fact that the GT3 can only be had with a dual-clutch transmission, the Cayman GT4 "transmits its power solely through a six-speed manual transmission with dynamic gearbox mounts." Yeah. So take that. The extra power reduces the Cayman GT4's 0-to-60 mile per hour sprint to 4.2 seconds, a half second quicker than the 340-hp Cayman GTS, and bumps top speed up to 183 mph. An interesting nugget: Porsche says the Cayman GT4 runs the Nurburgring in seven minutes and 40 seconds, which it credits as the same time run by the 2011 911 GT3. Porsche has never offered a precise time for the current 911 GT3, saying only that it's "under 7:30," and Internet rumor (grab your salt lick) is that the not-yet-introduced GT3 RS has done a 7:20. We don't have all of its details yet – those will come closer to its introduction at the Geneva Motor Show next month – but we're told of a lot more 911 GT3 parts underneath, like the chassis that "consists almost entirely of components from the 911 GT3" and that all of its "technical aspects are based on the 911 GT3." If you want to take it further, the options sheet will include ceramic brakes and carbon fiber bucket seats. This new top-shelf Cayman gets to dealerships in the US in July with a starting price of $84,600 before a $995 destination charge. You'll find a few more bits of info in the press release below. A New Member of Porsche's GT Family The benchmark in its class: the Porsche Cayman GT4 Atlanta, Feb. 3, 2015 - Porsche's GT family is proud to announce the addition of an exciting new member: the Cayman GT4.
