Chevy Malibu Hybrid wins 2016 Connected Green Car of the Year

From the Washington Auto Show today, Green Car Journal's Ron Cogan announced three different fuel-efficient vehicle awards. They were: 2016 Connected Green Car of the Year: Chevy Malibu Hybrid 2016 Luxury Green Car of the Year: Volvo XC90 T8 2016 Green SUV of the Year: Honda HR-V The Volvo was nominated in two categories, but it did not win the Connected Green Car of the Year. Speaking of non-winners, the other green SUV finalists were the BMW X1 XDrive28i, Hyundai Tucson, Mazda CX-3, and Toyota RAV4 Hybrid. The other Luxury Green Car finalists included the BMW x5 xDrive40e, Lexus RX 450h, Porsche Cayenne S E-Hybrid, and the Mercedes-Benz C350e. Finally, the Audi A3 e-tron, BMW 330e, Toyota Prius, and Volvo XC90 T8 were the runners up for Connected Green Car. 2016 Connected Green Car of the Year, Green SUV of the Year, Luxury Green Car of the Year Winners Announced WASHINGTON, Jan. 21, 2016 /PRNewswire/ -- Green Car Journal has announced the winners of its prestigious 2016 Green Car Awards at a press conference held today during the Washington Auto Show's Public Policy Day in Washington DC. Distinguished as 2016 Luxury Green Car of the Year™ is Volvo's new XC90 T8. The Chevrolet Malibu Hybrid tops the field as 2016 Connected Green Car of the Year™ and Honda's HR-V earns Green Car Journal's 2016 Green SUV of the Year™. "These are stand-out vehicles in an increasingly sophisticated and appealing field of 'green' cars," said Ron Cogan, editor and publisher of Green Car Journal and CarsOfChange.com. "To make the cut as a finalist is a real achievement in itself considering the considerable competition in the market today. Rising to the top as award winners means these three exceptional vehicles set a benchmark in the auto industry's effort to create vehicles that are desirable and efficient, while also achieving environmental milestones so important for our driving future." The Green Car Awards are a key feature of The Washington Auto Show, the "public policy show" on the auto show circuit and one that puts a priority on safety and sustainability. "We are extremely proud of our partnership with Ron Cogan, whose eagerly anticipated suite of awards help shape the national conversation on the innovations that will drive our industry and country forward," said Geoff Pohanka, chairman of The Washington Auto Show.

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.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.
