Ford GT dominates Le Mans qualifying, gets slapped with performance adjustment

Fifty years after Bruce McLaren and Chris Amon drove the Ford GT40 to victory at the 24 Hours of Le Mans, Ford is poised for a historic return to the Circuit de la Sarthe. The new Ford GT took the top two qualifying positions in the LMGTE Pro class, and four of the top five. Ferrari's 488 filled in the rest of the spots in the top seven, the first two from AF Corse. In other words, we're primed for a reboot of the classic Ford-Ferrari feud at this year's race. Or not, as the ACO, which organizes the 24 Hours of Le Mans, announced sweeping pre-race Balance of Performance (BOP) adjustments this morning that make this year's GT class anybody's race. In LMP1, last year's overall winner Porsche locked up the top two spots with the 919 Hybrid and will lead the entire field at race start. Toyota's two-car factory effort followed with qualifying times 1.004 and 2.170 seconds behind the pole lap. Audi rounds out the manufacturer-backed LMP1 class in fifth and sixth. Full qualifying results can be found here. The storyline for the GT cars is perfect - some say too perfect. Ford's class-leading times came after BOP adjustment to the Corvette Racing C7.R before qualifying. BOP is intended to level the playing field in the class by adjusting power, ballast, and fuel capacity. (Check out this explainer video for more, or even just if you love French accents.) But the process is riddled with unknowns and ripe for accusations of sandbagging. That is, if the Ford cars were intentionally slow in practice they could hope for BOP adjustment to improve their race chances. On the Corvette side, last year's GTE Pro winner went from the top of the field to the bottom, barely improving from practice to qualifying. If you think Le Mans is as rigged at the NBA Playoffs, well, it's not that simple. Because if Ford and Ferrari held back until qualifying - the eighth-place Porsche 911 RSR is three-and-a-half seconds off the class pole time - it was a pretty dumb strategy. This morning, the ACO tried to put things back in order by limiting the boost in the Ford GT's twin-turbo V6 and adding 11 pounds of ballast. Ferrari was also given extra weight but allowed more fuel capacity. The Corvette and Aston Martin teams were both given breaks on their air restrictors, which will allow their engines to make more power. Both Ford and Porsche also received extra fuel capacity.

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.

Ringbrothers drops more hints about its wild SEMA creations

Ringbrothers isn't finished teasing its SEMA creations. First we got a sliver of rear quarter on a 1969 Chevrolet Camaro that revealed a bundle of carbon fiber and SEMA-obligatory deep-dish wheels. The Wisconsin tuner's now announced its litter of cars headed to the show and a few specs, along with two shadowy drawings. The Camaro, christened with the name Valkyrja and a two-tone paint job, gets stretched in two directions with severe fender flares to widen the body and an extended wheelbase. We're not sure what's happening with the Camaro's snout in the drawing, but under that bulging hood we'll find a 416-cubic-inch LS V8 from Wegner Motorsports. Wegner built the 416-cu-in supercharged LS3 V8 that powered Ringbrothers' 1,000-hp G-Code Camaro in 2016.  The second member of the gang is a 1969 Ford Mustang Mach 1 dubbed Unkl. The exterior begs for attention with a deep blue sea paint job, deep front chin spoiler, bulging hood, yellow brake calipers, and what looks like a racing number inside a roundel on the doors. Unkl gets its motivation from a 520-cu-in Boss V8 built by Kaase Racing Engines, rumored to throw about 800 hp.    Finally, Ringbrothers is bringing its Cadillac Madam V for another Las Vegas go-round after giving the custom coupe some updates. The Madam V is a 1948 Cadillac Series 62 fastback coupe body placed atop an ATS-V chassis, first shown in 2016. The firm didn't elaborate on the changes, so all we can expect for now are the coupe's postwar good looks mixed with new-millennium engineering, and a 3.6-liter twin-turbo V6 with 464 hp under that exceptionally long hood.    For any in attendance at the show, the Valkyrja Camaro debuts at the BASF booth on Tuesday, Nov. 5, 2019 at 9:30 a.m., the Unkl Mustang gets revealed a couple hours later at the Flowmaster/Holley booth, and the Madam V Cadillac will be on display throughout the show at the Ringbrothers booth.
