Ford also working on 200-mile EV to compete with Bolt, Model 3

The Chevrolet Bolt is on a lot of people's radars. You may have even noticed friends and colleagues who harbor very little interest in the automotive world, or anything labeled as "green," who have taken notice of a 200-mile electric vehicle coming out of Detroit. Mass appeal is the idea, after all. You can include Ford in the list of interested parties, in this case with the intention of taking direct aim at the Bolt – and, by proxy, the Tesla Model 3 – with an affordable, long-range EV of its own. Ford will unveil its own long-range EV, positioned to compete with Chevrolet, later this year, according to Automobile. Details are very scarce about Ford's plans, but we do know that the Bolt (or whatever the Chevy all-electric hatchback will end up being called) is expected to offer over 200 miles of driving between charges, with a sticker price around $30,000. The other major player, of course, is Tesla's smaller, more affordable sibling to the Model S. The Model 3, also slated to go on sale in 2017, should cost less than $40,000. While Tesla has established itself in the EV world, another long-range EV out of Detroit would win some customers from the California-based startup. For now, though, we'll just have to wait, as Ford remains tight-lipped about its plans for the car. Automobile predicts a possible unveiling at the Los Angeles Auto Show in November, what with California's EV mandate being a driver of strategy for various automakers. Most can agree, though, that a larger field of options – while not ideal for backers of the Bolt or Model 3 – will only benefit the car-buying public.

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.

Watch how Corvette Racing's new collision-avoidance radar system works

When it comes to technology used in racecars, we generally expect it to trickle down to production cars, not the other way around. Well, Pratt & Miller has developed a new rear-facing radar that operates in a similar fashion to what we're used to in modern blind spot detection systems, only it is also capable of tracking cars as they approach and relaying vital information to the driver via a large display screen.
The innovative radar system debuted at last weekend's 12 Hours of Sebring for Corvette Racing, and this system makes perfect sense for endurance races like this since the cars sometimes have to drive through the night and in poor weather conditions.
The radar can detect cars even with poor visibility, and uses easy-to-distinguish symbols for the driver to identify.
