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.

Sunday Drive: Tracking Tokyo's top performers

The big news of the week mostly came from Tokyo. All of Japan's biggest automakers made waves at the Motor Show, but the winner of the event has to be Mazda. The big Vision Coupe and little Kai Concept stole the show, won our hearts, and earned a ton of attention for the automaker. We can't wait to see how these two concepts impact the design, engineering, and technology of future production models. Take a look at our mega image gallery post below to see everything in high-resolution glory. Interestingly, the single biggest click-magnet of the 2017 Tokyo Motor Show was the BMW X2. We shouldn't be surprised. Crossovers of all shapes and sizes dominate the American marketplace, and the X2 is clearly the most attractive of BMW's even-numbered, coupe-influenced X models. Plus, it's headed for production, with sales starting in the spring of 2018. Moving past the Tokyo Motor Show, Autoblog readers are apparently very interested in the 2019 Chevy Camaro. Spy shots of just about every iteration of Chevy's muscle car lit up the 'net last week, leaving us very interested in seeing what's hiding behind all that camouflage. As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2017 Tokyo Motor Show | Mega Gallery Mazda Vision Coupe | Tokyo Motor Show's big, sensuous 4-door Mazda Kai concept hints at a more muscular, refined Mazda3 2018 BMW X2 crossover revealed, adorned in gold and silver 2019 Chevrolet Camaro: 1LT, SS, ZL1 all spied with updated styling

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.
