Cadillac boss: We will have diesels

Johan de Nysschen doesn't usually mince words about his plans, and the Cadillac boss says that diesel-fueled models are on the horizon for the luxury brand in the US by the early 2020s. The four- and six-cylinder engines under development would launch first in Europe about 2019. "We will definitely bring them to the US," de Nysschen said during a press event, according to Automotive News. Unfortunately, the Cadillac president isn't saying which models would get the diesels, yet. This plan has been in the works for at least several months, and Cadillac made mention of the two oil-burners earlier this year during the unveiling of its new V6 engine. De Nysschen broached the possibility during an interview at the 2015 Detroit Auto Show, and he also referred to the inclusion of hybrids and plug-ins into the company's lineup at that time. Last year, a rumor suggested the addition of a V6 turbodiesel into the Escalade range. There were also rumblings of an oil-burning ATS during that model's launch. While Cadillac is no stranger to offering diesels in Europe, the decision to develop these new ones could come at an inopportune time. Governments there are rapidly moving against the fuel in favor of electrification. Tighter emissions regulations could also be on the way for the EU. Related Video:

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.

Weekly Recap: GM scales back as Russian auto market teeters

General Motors' extensive plans to scale back its Russian operations are the latest sign the automotive market in the former superpower is collapsing – and there are few signs of recovery. GM said Wednesday it will stop selling mainstream Chevrolets and shutter the entire Opel brand in Russia. The moves leave GM with a luxury-focused presence consisting of Cadillac and Chevrolet's Corvette, Camaro and Tahoe. The cutbacks will be completed by the end of the year. The automaker will also idle its factory in St. Petersburg and end a contract-assembly agreement with Russian manufacturer GAZ. "We had to take decisive action in Russia to protect our business," Opel Group CEO Karl-Thomas Neumann said in a statement. "We confirm our outlook to return the European business to profitability in 2016 and stick to our long-term goals." GM is the latest automaker to scale back in Russia as the economic conditions, volatile currency and uncertainty over the conflict in the Ukraine all have sandbagged new car sales. Last month, vehicle sales collapsed 38 percent in Russia to 128,298 units, according to the Association of European Business, which records sales. Joerg Schreiber, chairman of the AEB automobile manufacturers committee, didn't even feign optimism in a statement announcing the figures. "The market is entering a very difficult phase now, and February is only the beginning," he said. "Industry sentiment is the next few months will be extremely difficult and the market bottom has yet to be found." The dovetails with industry experts, who predict the Russian auto sector will remain in the doldrums. IHS said earlier this year it expects Russia's sales to slip to just 1.8 million units in 2015, which is a 40-percent drop from 2012.
