2016 Chevrolet Colorado Diesel First Drive [w/video]

The first thing you notice inside the diesel Chevy Colorado is that it's quiet. Almost too quiet. A lot has been done to quell noise and vibration with this new powertrain, and it shows – or rather, doesn't. There's some characteristic diesel clatter at idle, but even then it's distant and practically disappears as you start moving down the road. At full throttle, when the engine is at its noisiest, the sound isn't particularly diesel-like, just a pleasant intake breath. The accompanying smoothness is almost eerie. When we ask where all the noise went, Chevy's engineers, marketing guys, and PR reps all explain that this refinement is what Americans want. We're still not sure. This is a truck, after all, and the diesel pickup customer is different from the guy buying a diesel Cruze for his highway commute. Chevy contends that they're also not the same as the buyer of a Silverado HD. Although this 2.8-liter Duramax four-cylinder has been in service elsewhere around the globe, its first US application is in the Colorado and its GMC Canyon twin. The engine puts out 181 horsepower and 369 pound-feet of torque, and it does so unobtrusively as a result of a lot of modifications for our market. To keep normal diesel sensations out of the cabin, the intake and oil pan both get acoustic treatments. A new, thicker material is used for firewall sound deadening. Redesigned balance shafts have tighter tolerances to increase smoothness. The diesel powertrain is smoother than the Colorado's gasoline V6. One of the more interesting and certainly unexpected vibration-reduction changes is a special torque converter from German supplier LuK equipped with a centrifugal pendulum absorber. This pendulum spreads from the center of the torque converter as engine speed increases and is tuned to absorb the four-cylinder's second-order vibrations, not just those in a narrow frequency band. It does an admirable job, especially considering the engine's biggish, 0.7-liter cylinders, which lead to bigger vibrations. The result is a powertrain that's smoother than GM's (not particularly smooth) corporate V6, which is available in the standard Colorado. It's quieter than a Cruze diesel and even out-softens some gas direct-injection engines on the market. Paradoxically, it may be the most refined of all of the Colorados. No vibration comes through the steering wheel, pedals, floorboards, or even the rearview mirror. But you can tell it's a diesel when you hit the throttle.

GM's labor deal with UAW union on verge of ratification

Nov 15 (Reuters) - General Motors' tentative labor deal with the United Auto Workers (UAW) union closed in on ratification as the votes were counted on Wednesday. Following the approval earlier in the day by more than 60% of union members at the Detroit automaker's large Arlington, Texas, assembly plant, additional votes in favor have the deal close to clinching majority approval. The number of union locals, most of which are smaller, still to report vote totals is not large. After several large assembly plants voted against the deal earlier on Wednesday, some media had reported the deal was heading toward failure. But Arlington's support, followed by strong voting in favor by smaller warehouse and parts facilities, has put the deal on the brink of approval. This would mark the first ratification of a deal, which runs through April 2028, with one of the Detroit Three automakers. Ford and Stellantis voting is still under way, and workers at both companies were favoring ratification by comfortable margins. The UAW's GM vote tracking site currently shows approval of the contract leading by a 54% to 46% margin with almost 32,000 workers having cast votes out of about 46,000 UAW-represented GM workers. The Arlington plant, with about 5,000 UAW members, has the most of any GM plant. Voting officially ends on Thursday at 4 p.m. EST, although most votes will be cast on Wednesday. The UAW went on strike for more than six weeks against the Detroit Three, seeking better wages, working conditions and cost-of-living adjustments. All three companies agreed to tentative agreements about two weeks ago. Workers at other GM assembly plants voted against the deal, including 60% of workers at its Fort Wayne, Indiana, truck plant, 53% at its Wentzville, Missouri, plant, 58% of workers at GM's Lansing Grand River plant and 61% of workers at the Lansing Delta Township plant. Seven of GM's 11 assembly plants rejected the deal. In addition to Arlington, workers at plants in Detroit, Fairfax, Kansas; and Lake Orion, Michigan; approved the agreement. Only nine facilities are still listed without vote totals on the UAW vote tracker, including GM's Lockport, New York, components plant with about 1,200 members. Those voting in favor of the agreement have a lead of almost 2,500 and many of the facilities still to come include workers who stand to receive large pay increases upon ratification.

GM recalls Chevy Express, GMC Savana over rollaway concern

The National Highway Traffic Safety Administration has issued a recall notice for a small number of General Motors fullsize vans due to possible rollaway concerns. On certain 2013 Chevrolet Express and 2013 GMC Savana models, it is possible to remove the key from the ignition without the shifter being in park.
Only 980 total units are being affected by this recall, and GM is fixing the issue by replacing the ignition cylinder and associated keys. Affected Chevy vans were built during most of November and December while its GMC counterpart was only built for a week in November. The recall goes into effect on January 23, and to find out if your vehicle applies to the recall, the GM and NHTSA contact numbers can be found on the official recall notice, which is posted below.
