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.

Chevrolet considering midsize crossover to slot between Traverse and Equinox

Crossovers are the new hotness, and automakers are looking to cash in by offering a size and shape for every customer. With Chevrolet's debut of the new 2018 Traverse in Detroit, which grew ever so slightly compared to the first-generation model, there is now a midsize-crossover-sized hole between the three-row Traverse and the compact Equinox. When asked about that obvious space, a Chevrolet spokesperson told us the company is looking into the possibility of expanding its crossover lineup. It should be a relatively simple thing to do, since all it would take is reskinning and rechristening the GMC Acadia with a bow tie, and we all know how much GM loves platform sharing. Although they're now different sizes, the new Acadia and Traverse still use the same platform; the Acadia is now on a short-wheelbase version of the C1XX while the Traverse uses long-wheelbase C1XX parts. A short-wheelbase Chevy built on the C1XX likely would be differentiated visually from both the Acadia and the larger Traverse. It may seem like flooding the lineup with more and more models would cannibalize sales of existing ones, but Chevrolet said it would rather have customers stay within the brand rather than going to another automaker. There have been whispers that some form of the Blazer name (possibly TrailBlazer) may make a return on a midsizer, but if it does don't expect an old-school body-on-frame SUV like the old one. In the end, if Chevy builds it, customers will come. Related Video:

2014 Chevrolet C7 Corvette wastes no time zooming into Jay Leno's Garage

Where else would you expect the 2014 Chevrolet Corvette Stingray to show up first? Although this time it isn't exactly in Jay Leno's Garage, Leno instead playing an away game at Brown's Classic Auto in Scottsdale, Arizona. Nor does Leno drive the car, instead taking an 11-minute walkaround of the new American sports car with General Motors design head Ed Welburn, the same man who recently brought by a string of classic Corvettes to the talk show host's California compound.
It is, admittedly, a love-fest for the American sports car now featuring 450 horsepower and 450 pound-feet of torque, but one that also features admissions about previous Corvette seats like "they were kinda rough," and the explanation that labeling the coupe "Stingray" means not having to call it "the base Corvette." On top of that, Welburn also explains the proper application of the term "dashboard." You can watch it all in the video below.
