GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

Genesis cars win accolades, offer value — so why are sales so bad?

My high-school buddy Brent Cormier was so smitten with the Genesis G80 when he saw it at an event I hosted at SXSW in 2016 he bought a used 2013 Hyundai Genesis a short time later and fell in love with the car. "It surpasses my every expectation," said Cormier, a self-described "renaissance man" who owns and runs a real estate agency with his wife Laura, is a food service executive chef and part owner of Austin-based Thin the Herd Guitars. "I was locked into Mercedes and Audi for 10 years," he added. "And felt trapped in an endless pit of maintenance costs." After owning the Genesis over the past two years — including using it as an Uber and Lyft driver to earn extra cash — Cormier learned what some frugal luxury sedan buyers and a handful of car reviewers have discovered: Genesis offers great bang for the buck compared to other premium brands and can compete with the best in terms of performance, features and comfort. Hyundai's luxury brand also earned a prominent third-party endorsement last week when for the first time Genesis topped J.D. Power's 2018 APEAL study, surpassing German luxury-performance icon Porsche. The APEAL study (which stands for Automotive Performance, Execution and Layout) "measures owners' emotional attachment and level of excitement across 77 attributes," ranging from performance to comfort, and asks nearly 68,000 owners of new 2018 models to score vehicles on a 1,000-point scale. In its second year ranked as a stand-alone brand, Genesis earned an APEAL score that bumped it up 15 points to 884 and helped push it past Porsche — and past BMW, Lincoln, Mercedes-Benz, Audi, Volvo, Cadillac, Land Rover and Lexus, in order of ranking. Last month, Genesis also topped J.D. Power's Initial Quality Survey (IQS) for the first time this year. And both its models were awarded Top Safety Pick Plus ratings by the Insurance Institute for Highway Safety, among 11 Plus ratings in all for Korean vehicles. Despite high J.D. Power rankings and great reviews, Genesis U.S. sales were off 50 percent for the first six months of 2018 compared to 2017, and in June Genesis sold only 796 vehicles — the first time U.S. numbers dropped below 1,000 in a month. Part of Genesis's APEAL and IQS success can be attributed to its small product lineup: just two models, the G80 and G90 sedans, with a third, the 2019 G70, launching later this year. And while those numbers may help in J.D.
