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.

Three automotive tech trends to watch in 2018 and beyond

Every year, technology plays a bigger and bigger role in the auto industry. To put things in perspective, 10 years ago iPod integration and Bluetooth were cutting-edge in-car innovations, and smartphones and apps weren't yet a thing since the first iPhone was only about six months old. And I can't recall anyone talking about autonomous cars. Compare that to today, with mainstream coverage of the auto industry dominated by autonomous technology, along with electrification and almost every move made by Tesla. These three topics were the most significant trends of car tech in 2017 and I believe they will continue to shape the auto industry in 2018 and beyond. Let's examine them. Full Autonomy Gets Closer to Reality While there were many developments this year that indicate we're inching closer to fully autonomous vehicles, I was behind the wheel for hours to witness one of them. In October I had the chance to test Cadillac Super Cruise on a 700-mile, 11-hour drive from Dallas to Santa Fe – and had my hands on the wheel for maybe 45 minutes max throughout the entire trip. Super Cruise is far from making the Cadillac CT6 or any GM vehicle fully autonomous, and has limitations such as functioning only on pre-mapped main highways. While it simply adds a layer of lane centering to adaptive cruise control, the technology will go a long way in making mainstream drivers more comfortable with letting machines take over. On a separate front, GM is pushing ahead with fully autonomous vehicles and announced last month that it plans to launch of fleets of self-driving robo-taxis in several urban areas in 2019. While most automakers are also in the race to make autonomous cars a reality, GM's turbocharging of its efforts appeared to be in response to Waymo, which announced just weeks earlier that its Early Rider Program in the Phoenix area would go completely driverless. The Early Rider Program launched last April, offering the public a chance to ride in Waymo's autonomous Chrysler Pacifica minivans. In this new phase of testing, Waymo is using its own employees as guinea pigs instead of the public while the vehicles operate without a human behind the wheel, and takes another giant step forward for fully autonomous driving.

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:
