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.

Top Gear drag races VW Golf R against McLaren 675LT and Porsche 911

Top Gear's latest quarter-mile drag race in the collects three very different performance vehicles: the 296-horsepower Volkswagen Golf R, 424-hp Porsche 911 Carrera GTS, and 666-hp McLaren 675LT. While each of these cars sit near the top of their segment, they each come from totally different rungs of the sports car price ladder. Spoiler alert, the Golf R doesn't win. But the final results illustrate the diminishing returns of price and performance. For example, the McLaren is only about a second quicker than the Porsche to 60 miles per hour, but the 675LT costs over 2.5 times more that the GTS. Related Video:

Porsche Macan to debut at LA Auto Show

Auto Express reports Porsche will unveil the upcoming Macan SUV at this year's LA Auto Show. Citing an unnamed "insider," AE says that the five-door will bow with engines, suspension and interior architecture that will help differentiate it from its Audi Q5 chassis mate. Big shocker there. We've been hearing the same line since we first caught word of the Macan back when it was still rolling around under the Cajun name. The report does shed some light on the model's pricing, however. That same insider says the Porsche Macan will carry a price tag of 36,000 pounds.
What does that mean for American buyers? Do some quick math based on current conversion rates, and average UK and US prices, and we come up with a sticker of roughly $42,000 here in the land of the free. That fits in line with the rest of the company's stable, with the larger Cayenne starting at $49,600.
Still, we'll wait for more concrete word before jumping behind the AE report wholeheartedly. The 2013 LA Auto Show gets going in late November.
