Silverado HD, Touareg V10 TDI face off in diesel tug-of-war

A couple weeks ago, we watched a Chevrolet Silverado get dominated by a Dodge Ram Heavy Duty in a fullsize pickup tug-of-war, but in that truck's defense, Chevy's Vortec gas engine was no match for the torquey Cummins turbo diesel. For our next round of vehicular tug-of-war, a Duramax-powered Silverado HD takes on Volkswagen Touareg V10 TDI.
Now, on paper, putting the Duramax V8's 365 horsepower and 660 pound-feet of torque up against the V10's 310 hp and 553 lb-ft looks like an easy win for the Bowtie, but unfortunately, this battle has a similar result as the Dodge versus Chevy video, with the Silverado smoking its tires trying to move forward as it gets pulled backwards. Put another way: YouTube 2, Chevy Silverado 0.
It just goes to show, though, that big tires, bolt-on fender flares and goofy smoke stacks don't improve your towing abilities. Besides, what did the Silverado driver expect when the Touareg V10 TDI has towed a Boeing 747 in the past?

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.

GM will make Chevy Volt production announcement tomorrow

Thing are apparently happening to get the next-generation Chevy Volt ready for public consumption. The most obvious proof is in a preview of an announcement (possibly coming tomorrow) that the two main places where General Motors gets the Volt ready -the Detroit-Hamtramck Assembly Plant and the Brownstown Township battery assembly facility - will be getting big money upgrades and lots of new positions. The Hamtramck plant builds the Volt and its fancier cousin, the Cadillac ELR, as well as the global versions of the Volt. The Detroit News reports that GM will add 1,400 jobs and spend roughly $450 million at the two locations in order to build the redesigned Volt. What's less clear is exactly what the updates will bring us. We've heard that the new volt will be a 2016 model and come on a new chassis. Speculation in The Detroit News about tomorrow's announcement runs the gamut from a new compact PHEV with less electric range and a lower price (which makes sense) to an updated Volt with more electric range (heard it before) to a new all-electric vehicle (the moon shot). If there's any hints to be gleaned in the international Volts, there are also reports coming in that the Opel brand will get an all-electric vehicle that is cheaper than the Ampera. Read into that what you will. We pestered GM's Kevin Kelly on the new Volt (again) and he said (again) that he couldn't give out any more detail other than what's been reported. He just told AutoblogGreen that there will be an announcement tomorrow and that it will be about the Hamtramck and Brownstown facilities and involve the Volt. So, stay tuned.
