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.

Chevy says not to look at the 2019 Silverado's fuel economy rating

The 2019 Chevy Silverado is hitting dealerships soon, and one of the most notable changes for the new full-size pickup is the addition of a 2.7-liter turbocharged inline-four. The engine replaces the naturally-aspirated 4.3-liter V6 in volume consumer models like the Silverado LT and promises more power, less weight and — most importantly — better fuel economy. The thing is, the gains in efficiency haven't been as dramatic as some might have hoped, especially when stacked up against competitors from Ford and Ram. As Automotive News reports, GM's response is a little murky. First, let's talk numbers. We're pulling all figures from FuelEconomy.gov, the official U.S. government source for fuel ratings. Fuel economy numbers on trucks vary greatly based on a number of factors. Bed and cab configuration play a part, but so does a four-wheel-drive system. You also have to factor in tires, transmissions, rear-axle gearing, hybrid systems and cylinder deactivation. Things like that can make the difference between best- and worst-in-class. The EPA's website doesn't give enough information a lot of the time, so there's really no easy way to compare apples-to-apples. First, take a look at the ratings for the 2019 Silverado. A 2.7-liter model with two-wheel drive is rated 20 city, 23 highway and 21 combined. That's both better and worse than a two-wheel drive 2018 Silverado with the 4.3-liter V6 (18 city, 24 highway and 20 combined). The updated 2019 Silverado with a 4.3-liter V6 has yet to be rated. With less weight and a smaller engine, many hoped Chevy would make bigger gains. It's unusual to see any decrease in a fuel economy metric these days. GM says that it's not done tuning the new 2.7-liter engine, so fuel economy could theoretically increase. Expanding further, a V8-powered 2019 Silverado (17 city, 24 highway and 19 combined) actually gets better highway fuel economy than a turbocharged four-cylinder powered truck in certain configurations, even if the latter has a better overall average. But that's only with two-wheel drive, the 8-speed transmission and cylinder deactivation. A Silverado with the 5.3-liter V8 and a 6-speed automatic is rated at 15 city, 22 highway and 17 combined. The biggest issue with the Silverado 2.7-liter doesn't come from within GM itself but from Ford and Ram. GM cites the Ford F-150 with the 3.3-liter V6 and the Ram 1500 with the 3.6-liter V6 as the closest competitors to its new 2.7-liter inline-four.

GM seatbelt recall affects over 1m Silverados and Sierras

The Basics: General Motors will recall 895,232 examples of the 2014-2015 Chevrolet Silverado and GMC Sierra 1500 pickups in the US. The campaign will also affect the trucks in markets worldwide, and the total number the company will recall is 1,037,982. The Problem: A steel cable connects the seatbelt to the vehicle, but over time repeated bending can cause the part to fatigue and separate. Injuries/Deaths: None reported. The Fix: Dealers will enlarge the side shield opening and install a pusher bracket on the tensioner. Technicians will also replace the entire tensioner assembly if necessary. If You Own One: GM will contact owners about the recall. The company hasn't said when those notifications would begin. More Information: There are still about 3,000 new examples of these older pickups at dealerships. Until mechanics fix the problem, these vehicles are subject to a stop-sale. Similar problems have affected the General's vehicles in the past. In 2015, the company recalled over 400,000 units of the 2011-2012 Chevrolet Malibu for fatiguing cables. It also hit over a million Lambda platform crossovers in 2014. GM Recalling Certain 2014-15 Pickups to Repair Seat Belts DETROIT – GM is voluntarily recalling 895,232 model year 2014-15 Chevrolet Silverado and GMC Sierra 1500 pickups in the United States because the flexible steel cable that connects the seat belt to the vehicle can fatigue and separate over time as a result of the driver repeatedly bending the cable when entering the seat. This issue was discovered through warranty data, and there have been no reports of crashes, injuries or fatalities related to this issue. For trucks in the field, dealers will enlarge the side shield opening, install a pusher bracket on the tensioner, and if necessary, replace the tensioner assembly. The recall in the United States includes a stop-sale of approximately 3,000 new 2014 and 2015 model year pickups still on dealer lots. Dealers will repair the vehicles prior to delivering them to customers. Customers will be notified by General Motors. They also can look up their vehicle identification number (VIN) at either https://vinrcl.safercar.gov/vin/ website or at https://my.gm.com/web/portal/ownercenter to see if their vehicle is part of the recall. GM also will voluntarily recall and repair these models in other countries where they are sold, including Canada, Mexico, and several countries in Latin America and the Middle East.
