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.

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.

Fewer than 1 in 3 Chevy dealers earn right to initially sell C7 Corvette

Looking to make the launch of the 2014 Corvette Stingray as efficient as possible, Chevrolet will be limiting the numbers of its dealers that can sell the all-new coupe and convertible. According to Automotive News, sales of the C7 Corvette will initially be limited to less than a third of Chevy's total dealership network when the 'Vette goes on sale this summer.
Only 900 dealers out of more than 3,000 locations nationwide will be allowed to sell the new Corvette at first, and the reason for this is so that there are no shortages at dealers that can actually get the cars sold. The article says that the 900 dealerships chosen represented 80 percent of total Corvette sales in 2012.
Some of the requirements dealers had to make to get initial allocation of Stingray sales include having sold at least four Corvettes in 2012 and having a Corvette Stingray specialist who will be required to have gone through a training session costing more than $2,000 per attendee. Once demand for the 2014 Corvette Stingray begins to subside - approximately six to nine months after it goes on sale - then allocation could open up to more dealers, but the report indicates this could happen following the 2014 model year.
