GM Halts Sale Of Most Chevy Cruze Models

General Motors has told dealers to stop selling some 2013 and 2014 Chevrolet Cruze compact cars. But the company won't say why. Dealers say stop-sale orders are routine and almost always made to fix a safety problem. They received the order in an e-mail Thursday, but no reason was given. The move comes as GM deals with fallout from a delayed recall of 1.6 million older small cars to fix an ignition switch problem. The company says the switches can slip out of the run position and shut down the engine. That causes loss of power steering and brakes and disables air bags. GM says the problem has been linked to 31 crashes and at least a dozen deaths. Spokesman Greg Martin says he has no details on the Cruze.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

The Opel GT is the concept General Motors should build for the US

Now is the time. General Motors should double-down on performance cars and build the Opel GT concept that's set to debut next week at the Geneva Motor Show. Better yet, sell it in the United States as the Chevy GT. Consumers are showing a thirst for performance cars not seen in decades. Ford has them coming in waves, with everything from the F-150 Raptor to a hotted-up Fusion. FCA US is unrepentantly building loads of Hellcats. GM should respond. The General's cupboard is hardly bare. With the Corvette, Camaro, and Cadillac's V-Series, GM has more than enough to compete with its crosstown rivals and anything Europe or Japan can throw at it. But there's also an opportunity. There's not many front-mid-engine, rear-wheel-drive, two-seat sports cars out there like the Opel GT concept. A Chevy GT that used that layout and captured some of the concept car's proportions and curves would ignite a different kind of passion in enthusiasts. It would be Miata-like. With Chevy branding, this sports car would be the everyday exotic. The concept has a turbocharged 1.0-liter three-cylinder engine, which makes about 143 horsepower to motivate a structure that weighs less than 2,200 pounds. It can hit 60 miles per hour in less than eight seconds. All of those numbers are within the front-engined Miata's territory. This new Opel is inspired by two great mid-1960s concepts that helped put its design studio, and that of its sister brand, the British Vauxhall, on the map. (The GT concept is also technically a Vauxhall, as the brands are linked in GM's European strategy.) One of them, the '66 Vauxhall XVR remained a concept. The '65 Opel Experimental GT was on the road by 1968. That shows this is doable. There's precedent. The Saturn Sky and Pontiac Solstice shared a chassis with a modern GT during that trio's brief run. If GM ever makes this concept, Opel and Vauxhall should get their versions. But Chevy is the one that could make this car a global icon. Chevrolet GT. Make it happen. News & Analysis News: The potential return of the Ford Bronco is generating a ton of attention. Analysis: That's not news, per se. But when the Bronco6G.com fan site did a rendering of a next-generation Bronco, it almost broke the Internet. Everyone from Automotive News to Jalopnik picked up the illustrations. Our own post has drawn a lot of traffic and passionate responses. People are clamoring for the Bronco's return.
