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.

Porsche still deciding on one or two new 911 plug-in hybrids

Back in March, Porsche CEO Oliver Blume told Autocar that the coming Porsche 911 plug-in hybrid "will be the most powerful 911 we've ever had." That quote portended a 992-series 911 with 700 horsepower or more. A new report in Auto Express, however, suggests Porsche is having energetic debates about just what the 911's hybrid strategy will be, and that the only agreed-upon plug-in hybrid 911 so far is a milder version to sit in the middle of the range. Putting all our rumors in a row, in January, Automobile reported on an electrically-assisted 911 with 485 hp and 561 pound-feet of torque. The new AE piece effectively endorses that, saying the mid-range hybrid would follow the program established by the all-wheel drive Cayenne e-Hybrid that produces a combined 455 hp and 516 lb-ft. The 911 would naturally use a flat-six instead of the Cayenne's 3.0-liter V6, and the sports car would be tuned for better sound response and sharper reflexes. AE says fuel economy for this hybrid should be at least 80 eMPG, with emissions of less than 80 grams per kilometer. The current base Carrera is currently rated at a maximum 38.2 mpg in the UK, with minimum emissions of 169 g/km. The hybrid, fitted with a double-clutch gearbox and Porsche's mechanical all-wheel-drive system, could run from a stop to 62 miles per hour in less than four seconds, making it more efficient than a base Carrera and much faster than a Carrera 4S. AE says there remains only "the potential for Porsche to add a second, more powerful hybrid 911," and says its sources claim that's what's "causing the most consternation behind closed doors." This one would be the twin-turbocharged, 700-hp beastie that, as a series production car, would have a hard time not usurping the 540-hp Turbo, 580-hp Turbo S, and 607-hp Turbo S Exclusive. True, the hybrid would be handicapped with a 550-pound battery pack, but the instant acceleration and handling benefits of electric AWD — with no connection between the axles — could provide the final edge over the other three. As such, it makes sense that there'd be a whole lot of debate about a flagship 911 hybrid. On the other hand, such a monster seems like an eventuality in view of Porsche's electrified aspirations, the lessons gained from the 918 Hybrid and the 919 Hybrid Le Mans racer, and the fact that CEO Blume has already spoken. The Stuttgart carmaker expects a sales mix of 25 percent electric, 25 percent hybrid, and 50 percent conventional powertrains by 2025.

Ring Taxi BMW M3 chases an Aventador SV and Cayman GT4

On paper, a BMW M3 that's loaded with three passengers probably shouldn't have a chance at keeping up around a track with a Porsche Cayman GT4 and a Lamborghini Aventador LP 750-4 Superveloce. In the real world, driver skill and track knowledge can make all the difference, though. And when the M3 is a Nurburgring Taxi with a driver that knows the course incredibly well, we end up getting a fantastic lap like this one. The 'Ring Taxi driver starts by teasing his passengers that they'll see whether the Lambo is fast. Before the two of them get on track, the GT4 cuts in to join the party. What follows is a fascinating lap of the Nordschleife. It's impressive how the BMW driver's skill allows him to keep up with the two other cars and blow past tons of other traffic. During faster sections, the Porsche and Aventador start to pull away, but as soon as the course gets curvy again, the M3 is right back in the action. As the group pulls back into the parking lot, even the Ring Taxi driver sounds impressed with his performance. See the impressive show in the video above. Related Video:
