Ford Police Interceptors dominate Michigan State Police testing

Once again, Ford Motor Company builds the fastest police vehicles. The Blue Oval touted the news in an official release following Michigan State Police and Los Angeles County Sheriff's Department testing. Ford did very well. Except for one acceleration metric – zero to 10 miles per hour – the Blue Oval's Taurus and Explorer-based cop cars were the quickest, with particular praise coming for the EcoBoost-powered models, which bested Chevrolet and Dodge's V8-powered variants. Dearborn's products also posted the fastest average times around MSP's vehicle dynamics course. But it wasn't all positive for Ford. The only four-cylinder in the contest, the 2.0-liter, EcoBoost Ford SSP Sedan, had both the lowest top speed, 120 mph, and the slowest acceleration figures. It was also the slowest in track testing. Ford's products also failed to match the braking and top speeds of its rivals from Detroit and Auburn Hills – the rear-drive Charger Pursuit posted the best braking stats of the entire test, while the V8-powered Chevrolet Caprice hit the highest top speed, at 155 mph. Ford did score a top speed award, among SUVs, but at 132 mph, the naturally aspirated Police Interceptor Utility had to share its award with the equally fast, rear-drive Chevrolet Tahoe. The LA County Sheriff's timing isn't publicly available, but according to Ford, the EcoBoost-powered police cars put on a similarly impressive show for cops on the West Coast. We've assembled a spreadsheet on Google Docs that offers an easy to browse comparison of the different stats assembled by the Michigan State Police, and divided the vehicles between standard V6-powered sedans, high-performance sedans (EcoBoost and V8 models), and SUVs.

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.

Pure Vision Design TT Camaro has 1,400 reasons to want it

We've talked about Pure Vision Design before, a California-based company that made waves at last year's SEMA show with its Martini-liveried, Indy-car-powered Ford Mustang. That same car later starred in a Petrolicious video we showed you just a few weeks back. The company's latest creation is a menacing car it calls the Pure Vision Design TT Camaro. Based on a 1972 model, this car shares the Martini Mustang's clean styling and obsession with details.
Unlike the Mustang, which draws its power from a mid-60s Lotus-Ford Indycar engine, the "TT" in this Camaro's name implies something far more potent. The Nelson Racing Engines 427-cubic-inch V8 has been fitted with a pair of turbochargers, with a claimed output of 1,400 horsepower. That's almost 1,000 more than the Martini Mustang.
A six-speed Magnum transmission dispatches that power to the ground, while Pirelli PZero tires are tasked with (somehow) trying to grip the road. Baer brakes hide behind those HRE rims, while JRI coilovers and HyperTech springs bless the Camaro with some degree of competency in the bends.
