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.

CNG-powered Chevy Sonic, Cruze headed your way

The value proposition for a Crazy Diamond Performance CNG ride was a little bit better before gas prices took a dive in the past month. Still, the Michigan-based company, which converts some of Chevrolet's compact vehicles to run on compressed natural gas, received approval late last month from the US Environmental Protection Agency (EPA) for two of its conversion models. And CNG is still pretty cheap. Crazy Diamond will start selling CNG versions of both the Chevrolet Cruze and Chevrolet Sonic. The startup will target fleet operators looking to cut both refueling costs and their carbon footprint. CNG can be found in much of the country in the low $2 range, while the average CO2 emissions are about 25 percent less than those of similar gas-powered vehicles. Average gas prices have tumbled by more than 30 cents a gallon in the last month, according to AAA, but they're still at close to $3. The two models will be able to go almost 300 miles on a full tank of CNG. Crazy Diamond said this summer that it would start selling converted a CNG-powered Cruze that delivers 130 horsepower for as low as $26,000. The turbocharged version goes for about $28,000. Take a look at Crazy Diamond Performance's celebratory press release below. Crazy Diamond Performance recieves EPA approval on its CNG Cruze and Sonic CDP receives EPA approval for its Mono-Fuel CNG Cruze and Sonic. Shelby Township, Michigan, October 30, 2014– Crazy Diamond Performance (CDP) receives EPA approval on its Mono-Fuel Compressed Natural Gas (CNG) Chevrolet Cruze and Chevrolet Sonic. Crazy Diamond Performance has received EPA approval on two new mono-fuel small passenger vehicles, the CNG Chevrolet Cruze and CNG Chevrolet Sonic. These new mono-fuel CNG platforms are the first of a series of small and fuel efficient vehicles coming from CDP, where cost, low emissions and reduced fuel consumption is important for not only fleet owners, but to the general public as well. "Soon to be available, are the 1.8L and 1.4L Cruze and Sonic CNG retrofit systems. These two vehicles represent a change in the status quo, with an OEM level integration of the fuel system and its components" states Michelle Fern, Executive Vice President CDP Inc. These vehicles provide flexibility for fleets looking to purchase a domestic small mono-fuel passenger sedan, but have not had an option until now. There are significant emissions benefits over its gasoline counterpart, with an average reduction in Carbon Dioxide (CO2) of 25%.

2023 J.D. Power Initial Quality Study shows there's less quality than last year

Vehicle inventory, vehicle pricing, and the supply chain are finally showing improvement. Vehicle quality, on the other hand, is still going the wrong way. That's the takeaway from the 2023 J.D. Power Initial Quality Study that found overall problems exceeded last year's record high. The study surveyed owners of 2022-model-year vehicles to assess the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership. The average figure for the 32 ranked manufacturers in 2020 was about 166 problems per 100 vehicles. In the 2021 IQS, that dropped to an average of 162. For 2022, the average jumped to 180 problems. For 2023, the PP100 is up to an industry average of 192 — an increase of 30 problems per 100 vehicles in just two years. Let's get to the good news first: Dodge reclaimed the crown of having the lowest number of problems per 100 vehicles at 140. Buick won last year with 139 PP100, falling to third this year. Dodge was the first American automaker to top the IQS in 2021. Its return as the least problematic gives parent company Stellantis three wins in four years after Ram was crowned in 2021. It also gives U.S. brands a four-peat after Buick topped the chart in 2022 by having owners report the fewest problems. This year's top 10 is Dodge, Ram, Alfa Romeo, Buick, Chevrolet, GMC, Porsche, Cadillac, Kia, and Lexus. Stellantis gathered a few feathers for its cap, in fact. Maserati showed the largest improvement year-on-year, followed by Alfa Romeo, and Alfa Romeo posted the lowest PP100 among the premium class, beating Porsche and Cadillac. Alfa Romeo has been vocal about working to improve quality, mentioning Lexus as a target. Last year the Japanese brand finished sixth, the Italians finished near the bottom, between Jaguar and Mitsubishi. This year Alfa jumped to third, Lexus dropped to tenth. Ram was the third-best on the list of improvers from 2022 to 2023.   The individual model with the lowest PP100 is the Nissan Maxima. Now for the troublesome bits. In the words of Frank Hanley, senior director of auto benchmarking at J.D. Power, "The industry is at a major crossroad and the path each manufacturer chooses is paramount for its future.
