Porsche, Jaguar continue dominance in 2015 JD Power APEAL study

The top of JD Power's 2015 APEAL Study has not changed much in the last year. Porsche remains No. 1 with Jaguar nipping at its heels, although both premium brands saw their overall score fall compared to 2014. For those that need a refresher, the APEAL Study looks at how "gratifying" a vehicle is to own and drive, rating cars and brands on a 1,000-point scale. The industry average for 2015 has increased from 794 to 798, while the total number of automakers that finished above the curve increased from 16 to 20. While Porsche and Jaguar finished at the top, their scores dropped eight and seven points, respectively, to 874 and 855. The top "non-premium" brand was Mini, which scored an impressive 825, up from 795. If the BMW-owned British marque is still a bit too premium for your tastes, last year's non-premium winner, Hyundai, did climb five points and is this year's runner up. At the opposite end of the scale, Smart sits at the very bottom of the rankings, with a score of 683 (it didn't appear on the 2014 rankings). Fiat also dropped, from fourth worst in 2014 to second worst in 2015, despite the 500 being named most appealing city car. Subaru made an impressive climb, from third worst to seventh, falling just 10 points shy of the industry average and two points south of the non-premium average. In the individual vehicle segments, eight brands earned multiple awards, with Ford, Chevrolet, and Porsche earning three apiece. Surprise segment victories included the new Ford Expedition, which beat out Chevy's popular Suburban. The Infiniti QX80 bested the likes of the Cadillac Escalade and Range Rover for best large luxury SUV, and the Dodge Challenger beat its muscle car rivals from Ford and Chevy. Most of the victories, though, were quite predictable. The Mazda6 and CX-5 took wins for the midsize sedan and compact SUV categories respectively, while the Volkswagen Golf captured the compact car win. The Ford F-150 won the large pickup category, while the Porsche Cayman was named most appealing compact premium sporty car.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

Opel CEO talks new EV, will likely be fresh face for Chevy, too

The rumored demise of the Opel Ampera has been confirmed, but there's good news, too. Opel CEO Karl-Thomas Neumann has been busy Tweeting information about the brand's next plug-in vehicle, admitting that the Ampera is on the way out but that plug-in vehicles are here to stay. His Tweets, in full, read: After the eventual run-out of the current generation Ampera, we'll introduce a successor product in the electric vehicle segment. Our next electric vehicle will be part of our massive product offensive – with 27 new vehicles in the 2014-2018 time frame. We see eMobility as important part of the mobility of tomorrow and we will continue to drive down costs & deliver affordability. As we learned earlier this week, the Ampera will not be refreshed when the current Chevy Volt is updated, most likely because of slow sales. Opel sold just 332 Amperas in the first five months of 2014. For now, General Motors is still building Amperas in Michigan for export to Europe. So, what might this new EV mean for the General Motors plug-in fleet? Official spokespeople are being quiet, but we think it's safe to say the new EV Neumann is talking about is not simply a rebadged Chevy Spark EV. This is the first official word about an entirely new EV, and we expect it will come to both the Chevrolet and Opel brands.
