Surprise! GM putting aluminum in next-gen pickups

Last month, General Motors launched a series of ads touting the benefits of steel over aluminum – specifically, with regard to the Chevy Silverado versus the Ford F-150. (Kind of. We're not sure what a grizzly bear has to do with anything.) We took issue with the ads, with editor in chief Mike Austin saying they "reek of insecurity, and distract from the Silverado's strengths that could be used for positive advertising." But what bothers us more, is that yet another report surfaced claiming anti-aluminum GM will indeed use the weight-saving material in its next-generation fullsize trucks. On Tuesday, GM announced a $877-million investment for its truck plant in Flint, MI. But Reuters says that huge overhaul is because the trucks will use "substantially different equipment than the tools GM uses today." The report specifically states, "People familiar with the company's plans say GM's next-generation pickups and SUVs will make use of various materials, including aluminum and lightweight steel, to shed weight and gain fuel efficiency to meet tougher federal standards." The Silverado already uses a few aluminum components in the engine and hood, and if more widespread use will help GM build its best fullsize trucks ever, then that's great. Honestly, we have no reason to doubt that aluminum will be used in the next Silverado and GMC Sierra. We just hope GM remembers that nothing is ever truly deleted from the bowels of the Internet when it launches the subsequent "look how great aluminum is!" campaign.

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.

Diesel-powered 2020 Chevrolet Silverado, GMC Sierra get big price cuts

General Motors is reducing the price difference between its diesel-powered light-duty pickups and their gasoline-burning counterparts, according to a recent report. As of September 3, 2020, the Chevrolet Silverado 1500 and the GMC Sierra 1500 benefit from a $1,500 price cut when they're ordered with a turbodiesel under the hood. Enthusiast website GM Authority first reported the news after looking at internal documents sent to dealers across the nation. It wrote the discount applies to in-stock and in-transit units of the Silverado and the Sierra (pictured), and it added dealers will begin receiving amended window stickers on September 8. And, it's not just a quick, easy way for General Motors stores to clear out 2020 inventory. Incoming 2021 models will benefit from it, too. Chevrolet's cheapest diesel-slurping 2020 Silverado, a double-cab LT with two-wheel drive, now starts at $44,000 once a mandatory $1,595 destination charge enters the equation. For context, the same configuration costs $38,795 including destination when it's ordered with the 2.7-liter turbocharged four-cylinder, which is the smallest and cheapest engine on the roster. Selecting the more efficient engine option costs buyers $5,205. At the other end of the spectrum, the crew-cab High Country with a standard cargo box and four-wheel drive is now priced at $59,690. Walk a block to the GMC store, and you'll need to spend between $44,470 (double-cab SLE with two-wheel drive) and $61,685 (crew-cab Denali with a regular cargo box and four-wheel drive) for a diesel-powered Sierra. It doesn't sound like either company is making major mechanical changes to the trucks for 2021. Both are powered by a 3.0-liter straight-six Duramax engine, which makes 277 horsepower and 460 pound-feet of torque. Rear-wheel drive and a 10-speed automatic transmission come standard, and four-wheel drive is offered at an extra cost. In its most efficient configuration, the Silverado returns 23 mpg in the city, 33 mpg on the highway, and 27 mpg in a mixed cycle, impressive numbers for a body-on-frmae pickup that's as heavy as it is capable. Ram's diesel-powered 1500 posts EPA estimates of 22, 32, and 26, respectively. Ford pledged the recently-unveiled 14th-generation F-150 will offer a turbodiesel engine, too, but its fuel economy figures are not available yet.
