GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

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.

Motor Trend wheels the 2015 Corvette Z06

The new Chevrolet Corvette Z06 is capable of some absolutely wild metrics. Want proof? Carlos Lago from Motor Trend is here to break it all down. 60 miles per hour? 3.2 seconds. 60 to 0? 91 feet. Lateral acceleration? A staggering 1.16g, a figure that is the highest MT has ever recorded for a vehicle that isn't a race car. It's an utterly astonishing piece of work, this Z06, and just when you think it can't possibly get any more impressive, Randy Pobst hustles an auto-equipped Z06 around Road Atlanta in just 1:30. Aside from the eight-speed auto, Pobst's Z06 had the most aggressive aerodynamic package, the so-called Stage III. Take a look at the 650-horsepower Z06 in Motor Trend's latest video.
