2016 Cadillac CTS-V arrives with 640 hp, 200-mph top speed

Ask the company's executive team, and they'll tell you "this is the maximum Cadillac V-Series." It's the 2016 CTS-V sedan, and it packs the very best of what's possible at Cadillac. And the company says it doesn't think "anyone thought it was possible that we could push [the CTS-V] this far." The big news is what's underhood: General Motors' supercharged, 6.2-liter LT4 V8, tuned to 640 horsepower and 630 pound-feet of torque. That's 10 hp and 20 lb-ft less than the monstrous Corvette Z06, and the result is the most powerful car Cadillac has ever produced. With rear-wheel drive, launch control and the eight-speed automatic transmission (sorry, folks – no more manual transmission here), Cadillac says the 2016 CTS-V will sprint to 60 miles per hour in just 3.7 seconds, on its way to a top speed of 200 miles per hour. Naturally, Cadillac's engineers say they have tuned the CTS-V to ensure it can put all that power to the ground with the most precision and poise possible. That starts with the excellent Magnetic Ride Control active damping system (with a claimed 40-percent increase in responsiveness)and a 25-percent increase in structural stiffness that should improve overall handling and steering. What's more, a high-performance Brembo brake package comes standard, as do 19-inch alloy wheels wrapped in seriously sticky Michelin Pilot Super Sport tires that will reportedly offer 1g in lateral acceleration. Cadillac also says that all changes to the bodywork are functional. That includes a carbon-fiber hood, front splitter, rear spoiler and diffuser that are super light and aid with aerodynamics and weight reduction – all of which will be available as an optional package for folks who like the exposed carbon look. Inside, it's more of what we're used to on lesser CTS models, but there's newly optional carbon fiber trim, microfiber suede upholstery trim, and some seriously awesome Recaro seats. Additionally, as we exclusively reported earlier, Cadillac will offer GM's Performance Data Recorder in the CTS-V. It records high-definition video with data overlays that's sharable via social media. Beyond that, Cadillac will offer the usual smattering of tech goodies, including Siri Eyes Free, OnStar with 4G LTE, CUE infotainment with navigation and Bose audio. The CTS-V will launch later next year, following the debut of the smaller ATS-V. In the meantime, the sedan will officially bow at the 2015 Detroit Auto Show in just a few weeks.

Luxury car brands scrambling to avoid a blue Christmas

DETROIT — When financial markets surge to new records, sales of luxury cars usually rise, too. Instead, October U.S. auto sales reports on Wednesday showed that a collapse in sales of luxury sedans is accelerating. Consumers have gradually shifted over to luxury sport utility vehicles from sedans in the past decade, but the trend — which has occurred in both the non-luxury and luxury sedan segments of the auto market — was particularly pronounced in October. Sales of Daimler AG's Mercedes-Benz S-Class, long a global benchmark for large, premium sedans, plunged 49 percent in October, and are down 24.8 percent for the year to date. General Motors' Cadillac brand said it sold just 779 of its CTS sedans in October. Demand for that car, designed to compete with German luxury sedans, is down nearly 33 percent for the year. "There's still a significant portion of the market that wants a car, but I'm sure there were people who preferred a horse to a car at one point." Cadillac's best-selling model this year is the XT5 compact SUV, which has more than doubled sales from a year ago. The shift within the luxury vehicle market away from sedans toward SUVs of all sizes is forcing some of the most prestigious brands to scramble to add SUV models to their lineups or boost SUV production to meet demand. "In the short term, there will be pressure to add (consumer) incentives, cut production or both," said Cox Automotive analyst Michelle Krebs. "And we just don't see an end in sight to this trend." The Dow Jones Industrial Average has been trading at all-time highs, usually a good sign for luxury sedans, but as major automakers reported new U.S. vehicle sales for October on Wednesday, sales for passenger cars continued their slide while luxury SUV and crossover sales rose again. According to Kelley Blue Book data, in 2007 luxury sedans made up 7.6 percent of U.S. new vehicle sales, while luxury SUVs made up 4.2 percent. Through September this year, luxury SUVs made up just over 7 percent of the market, compared with 4.9 percent for luxury sedans. In the short term, luxury brands could use holiday season sales promotions to clear slow-selling sedans off dealer lots, analysts said. Toyota's Lexus brand said on Wednesday it will launch its "December to Remember" year-end sales promotion for the 18th straight year.

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.
