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.

2021 BMW M3 and M4 vs all the high-powered sport sedans and coupes

Should you have a found a way to get past that schnoz, you've probably digested some of the basic specs for the all-new 2021 BMW M3 sedan and M4 coupe specs. They're plenty impressive. There's also, basically, two sets of them thanks to the regular and Competition versions that differ in engine output and transmission type.  But how do they compare to other ultra sport sedans and coupes? Well, we were wondering that too, so we fired up the Autoblog Comparison Spreadsheet Generator 5000 (aka me chained to my computer in a dark basement).  Sadly, there are surprisingly few competitors for the 2021 BMW M3. Rival sedans include the Mercedes-AMG C 63 and the Alfa Romeo Giulia Quadrifoglio, along with the Audi RS 5 Sportback sedan/coupe/hatchback thing. There's no more Lexus IS F, the Cadillac CT4 Blackwing has yet to arrive and Jaguar doesn't offer a spicy XE R.  Happily, there are more coupe rivals for the 2021 BMW M4, including the two-door versions of the AMG and Audi as well as the Lexus RC F. I also included the Ford Shelby GT350 and Chevrolet Camaro SS 1LE. On paper, they align incredibly well. On the street and on a track, I can personally attest that these Americans are fully capable of keeping up and/or bettering the fancy-pants luxury brands (and let's not forget there are even more powerful, hardcore versions available). If they don't align in terms of price or prestige, whatever. OK, let's get to the spreadsheet. Let's start with the coupes and note that I didn't bother listing the dimensions for the M4 Competition and C 63 S as they are identical to their "lesser" siblings.  I won't bother burning words explaining what you can see on the chart. Instead, I'll point out a few things that stood out to me. First, BMW M comes awfully close to matching the output of AMG's twin-turbo V8 despite having two fewer cylinders. Similarly, Audi manages to better the 0-60 time of the M4 Competition and tie the C 63 S despite being WAY down on power. It's not like it weighs less. Magic? Second, and speaking of 0-60 times, remember the importance that transmission and drivetrain make with them. It's not just horsepower and torque. An automatic will be quicker and easier to launch than a manual, while all-wheel drive provides more instantaneous and beneficial grip.

Recharge Wrap-up: 'Racing Extinction' Tesla, Wards praises 3 hybrids

The makers of Racing Extinction used a tricked out Tesla Model S for their movie. The artists and activists used the electric car as a platform to project images from nature in various cities to raise awareness about imperiled wildlife. In addition to a the high-powered projector, the Model S features a electroluminescent paint job that emits light to mimic creatures found in the wild, such as bioluminescent sea life. It also has a thermal imaging camera in the front of the car with a filter to view CO2 emissions. Check it out in the video above, and read more at Ecomento. WardsAuto has named the 2016 Hyundai Sonata Plug-In Hybrid's powertrain to its list of 10 Best Engines. As the first plug-in hybrid to make the list, WardsAuto World Editor-in-Chief Drew Winter praises Hyundai engineers for their "impeccable job blending fuel efficiency with refinement and daily usability." Wards notes the car's smooth transitions between electric and hybrid modes, and a well-connected six-speed automatic transmission. Other electrified vehicles to make the list are the 2016 Chevrolet Volt and 2016 Toyota Prius. Read more from Hyundai, at Green Car Reports. FEV's plug-in hybrid battery pack has gone into vehicle series production. The 10-kWh battery pack, developed by the German development services provider, offers an all-electric range of about 30 miles. FEV says its battery management algorithms are just as important as choosing the right battery hardware. "The core system for the battery development is our own mature battery management system (BMS), now in its third generation, that together with optimized algorithms allows a very reliable and stable control of the battery," says FEV's Dr. Michael Stapelbroek. Read more at Green Car Congress, or in the press release from FEV below. Hybrid Vehicle Goes Into Series Production FEV development competence consists of batteries, controls, as well as complete drive systems FEV has demonstrated competence in the development of alternative drive concepts for almost twenty years. Most recently, yet another plug-in hybrid vehicle has gone into series production with technology provided by the Aachen-based developer. In addition to using an innovative transmission concept which is based on a FEV patent, FEV also developed the battery technology of the plug-in hybrid vehicle to series production readiness.
