Chevy updates Silverado HD with new towing equipment

Enamored by the updated Chevy Silverado released just the other day, but need something a little more heavy duty? Chevy isn't going to keep you around waiting for long, as it has now revealed a new Silverado HD as well. While the new Silverado 1500-series has been distinguished over the outgoing version principally by its revised styling, the updated Silverado HD is more about its enhanced equipment. It's got a new Digital Steering Assist system (on some models) designed to enable easier and safer towing. There's a new gooseneck/5th-wheel trailer prep package that enables Chevy's new heavy duty truck to tow as much as 23,200 pounds. And the interior equipment is augmented as well by a new MyLink system with seven- or available eight-inch display, Apple CarPlay and Android Auto capability, wireless phone charging and more. Buyers will be able to choose between two versions (2500HD and 3500HD), four trim levels, three cab sizes, two cargo box lengths, and numerous powertrain and drivetrain configurations for a staggering array of combinations. There'll also be several special editions and packages, like the Z71 for off-road use and Custom Sport Edition for a sleeker look, as well as chassis cab and CNG versions. Scope out the full details in the press release below and the fresh batch of images in the gallery above.

New Digital Steering Assist power steering on some double cab and crew cab models helps make hauling and trailering easier and more confident, with electronic controls that enhance road holding and stability on the highway – particularly on crowned roads – regardless of whether the truck is loaded. It also offers greater responsiveness and an improved steering feel. Digital Steering Assist is not available on Work Truck models or regular cab. There's also a new Gooseneck/5th Wheel Trailering Prep Package, with a spray-in bedliner, that makes Silverado HD models ready to tow larger trailers right from the factory.

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 execs fired over fraudulent India emissions testing

General Motors hadn't had a recall in India since 1995. That changed when it was discovered that certain employees were playing tricks with local emissions testing in order to ensure passing grades for engines. More than ten GM Powertrain employees in India and the US have been let go over the ensuing emissions flap, including Sam Winegarden, VP of global engine engineering, a man who has been with the company since 1969, leading development of some marquee powerplants.
According to Automotive News, an internal investigation revealed that employees "violated testing procedures," sometimes swapping specially prepared low-emissions engines during testing regimes for the Chevrolet Tavera SUV equipped with the 2.0-liter and 2.5-liter engines. Employees were also manipulating weights in order to get vehicles placed into different emissions categories. The discovery has led to GM recall the 114,000 Taveras produced over an eight-year period and halting their production and sale.
The Economic Times of India reports that the issue is due to "a faulty component." GM has developed a solution to the issue, and once it is validated in testing and approved by the Indian authorities, the recalled vehicles will be fixed at dealers and production will resume.
