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 recalls nearly 1 million vehicles for airbag defect

WASHINGTON — General Motors said on Friday it will recall nearly 1 million sport utility vehicles in the United States because the driver's airbag inflator may explode during deployment. The recall covers 994,763 Buick Enclave, Chevrolet Traverse, and GMC Acadia vehicles from the 2014 through 2017 model years with modules produced by ARC Automotive Inc. Dealers will replace the driver's airbag module. The National Highway Traffic Safety Administration said a driver in Michigan of a 2017 Chevrolet Traverse was in a crash in which the front-driver airbag inflator ruptured during deployment causing facial injuries. An April 25 inspection confirmed that the front driver airbag inflator ruptured in the vehicle. The National Highway Traffic Safety Administration (NHTSA) demanded the recall of 67 million air bag inflators because it believes there is a safety defect, but auto supplier ARC Automotive Inc rejected the U.S. regulator's request, documents released on Friday show. The auto safety agency said the inflators pose an unreasonable risk of death or injury. Even as ruptures mount, "ARC has not made a defect determination that would require a recall of this population," NHTSA said in its demand letter to the Tennessee-based company. "Air bag inflators that project metal fragments into vehicle occupants, rather than properly inflating the attached air bag, create an unreasonable risk of death and injury." GM said it was still investigating the issue with the assistance of a third-party engineering firm. "GM is taking this expanded field action out of an abundance of caution and with the safety of our customers as our highest priority," the Detroit automaker said. GM said it was aware of two prior ruptures of ARC-manufactured airbag inflators in 2015 Chevrolet Traverse vehicles, and GM conducted two earlier small recalls of about 3,000 ARC inflators. All three rupture events in Chevrolet Traverse vehicles involved the same inflator variant. ARC noted in a letter made public Friday that no root cause for those ruptures has been identified by ARC or GM. ARC said it was assessing the scope of GMÂ’s recall.  Government/Legal Recalls Buick Chevrolet GMC Safety Crossover SUV

GM's European Opel division may eventually go all-electric

General Motors' Opel division in Europe may transform itself into an all-electric vehicle maker by 2030. Granted, a lot can happen between now and then, including a potential buyout by French automaker PSA Group. Regardless, Opel appears to view its electric future beyond the Ampera-e, which is the sister vehicle to the Chevrolet Bolt, and more like Tesla. Opel CEO Karl-Thomas Neumann indicated that focusing on electric drivetrains would be a superior strategy to expanding its EV technology while pushing forward with conventional drivetrains, says Automotive News Europe, citing comments Neumann made to German publication Manager Magazin. General Motors could make the decision to move towards an all-electric vehicle line for Opel as soon as May. Of course, that depends on whether Opel is bought out by PSA, the parent country to Peugeot and Citroen. PSA is in talks to buy General Motors' Opel and Vauxhall divisions, though government and labor representatives in Germany have expressed concerns over potential job losses from the proposed buyout, Reuters says. Regardless, GM has hinted at expanding its electric-vehicle line far beyond the Bolt, which has a 238-mile single-charge range and debuted late last year. Mary Barra, in an interview with CNET, said the Bolt's all-electric platform could be applied to a "huge range of vehicles," though wasn't specific about additional EV models. Opel first showed off its Ampera-e at the Paris Motor Show last fall. The name of the model raised some eyebrows because the Ampera badge had been previously used by Opel for the sister version of the Chevrolet Volt extended-range plug-in. Either way, Opel is looking to take on Renault for electric-vehicle sales supremacy across the Pond. Related Video:
