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.

Here's how the EcoCAR 3 teams are going to green up their Camaros

Plug-in hybrids were probably not what the Dead Milkmen had in mind when they wrote their 1985 alt-punk classic Bitchin' Camaro (OK, we're not really sure what they had in mind), but we're certainly fans of the effort. The 16 college teams competing in the third version of the EcoCAR green-vehicle contest have declared which powertrains they will attempt to build for maximum environmental friendliness. They'll be working with 2016 Chevrolet Camaros that General Motors is donating to the competition. The US Department of Energy is also helping to fund the competition. Out of the 16, all but one will go with a plug-in hybrid powertrain which switches over from electric power to an engine powered by E85 (i.e., an 85-percent ethanol blend) when the juice runs out. Those schools include the University of Alabama, Arizona State, Mississippi State, Ohio State and Penn State. The lone dissenter is the team from the University of Tennessee, which is going with a hybrid vehicle powered by E10. This past spring, Ohio State was named winner of Year One of EcoCAR3, winning $10,000 in the process. THE Ohio State University (as students and alumni like to call it) also won the overall competition for EcoCAR 2 last year. The vehicle used in that project was a 2013 Chevrolet Malibu, and OSU also used a plug-in hybrid/E85 combo to take the big prize. Take a look at the list of schools and their powertrains of choice for EcoCAR 3 here. Related Video:

General Motors reportedly considering small electric pickup

General Motors is considering adding a small entry-level model to its range of electric pickups, according to a recent report. The carmaker is currently showing a prototype to a select group of customers to gather feedback about the model before executives decide its fate. Industry trade journal Automotive News claims that it saw the pickup during a workshop organized by General Motors and describes it as being "smaller than the Ford Maverick and the Hyundai Santa Cruz." For context, the Maverick stretches about 200 inches long, 73 inches wide, and 69 inches tall, so it's around 12 inches shorter, 11 inches narrower, and 10 inches lower than the recently-unveiled Chevrolet Colorado. It sounds like this little GM truck would be closer in size to the Brazilian-market Chevy Montana, pictured at top. But unlike the Montana, the model that Automotive News got a look at had two doors, a "low roofline," a four- to four-and-a-half-foot cargo box, and a design described as futuristic and sporty. If launched, the yet-unnamed pickup would be marketed as an "affordable" EV with a base price pegged under $30,000. However, that's a big if: the pickup — whose name hasn't been announced — hasn't been approved for production. "We're creating these to get a reaction and then to try to modify it or move on," Michael Pevovar, the director affordable EV and crossover design for Chevrolet, told the publication. "The input may come back that it's just too small, and that's okay," he added. If it turns out to be too small for buyers, General Motors hasn't ruled out building its entry-level electric pickup on a different architecture to make it a little bigger. It's too early to tell where the electric pickup would slot in the General Motors portfolio if executives approve it. Chevrolet immediately comes to mind, especially considering the sub-$30,000 price point. The model would make more sense with a bowtie on its front end than with a Cadillac emblem, GMC's trucks are normally positioned higher than Chevrolet's, and Buick hasn't built a pickup in many decades. Similarly, there's no word on when it would enter production or where it would be built. With that being said, there's very clearly a market for affordable, small pickup trucks. As of the third quarter of last year, Ford had sold more Mavericks than it had the Expedition or the Ranger. Hyundai hasn't sold as many Santa Cruz trucks, but it's still not too shabby, having beaten out the Venue and Accent last year.
