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.

Meet Alex Archer, the engineer behind GM's power-sliding center console

In 2009, a GM manager complained to a 59-year-old GM technician about the hassle of retrieving items from a pickup truck bed after driving shifted the cargo. In two days, the tech had come up with the ideas that, ten years later, would debut as the MultiPro tailgate. The engineering teams kept the tailgate secret in part by hiding mock-ups in a locked storage closet in GM's Vehicle Engineering Center in Warren Michigan for two years. A piece in the Detroit Free Press reveals that another storage closet in Warren would play the same role in a different cloak-and-dagger operation, this time for the power-sliding center console in GM's new full-sized SUVs. During a meeting in early 2017, bosses gave the job of the console's creation to 24-year-old design release engineer Alex Archer, just two years out of Stanford University with a degree in engineering and product design.  This time, the catalyst for the feature was an internal GM think tank called co:lab, where employees suggest ideas. Execs gave Archer the task because "They needed someone willing to ask a lot of questions," her 36-month mandate to produce a six-way console that could be a standard cubby or a gaping maw able to swallow four gallon jugs or hide a secret compartment. Clearly, she succeeded. It took Archer and the team nine months to devise a prototype, another six months to get the green light for production. As with the tailgate, the team working on the console grew to include designers, production engineers, and suppliers. Archer, now 26, shepherded the process, and her name is on the patent. "It took a ton of people, I'm just somebody who stuck with it the whole time," she said. GM like her work well enough to produce the "Day in the Life" segment above, five months before the world would hear about the console. Archer's path to engineering was as unlikely as getting the job for the console. She had entered Stanford with plans to be a doctor. But an innovation class during her freshman year, and a sophomore summer spent helping her grandfather rebuild a 1937 MG engine recharted her course. Her grandfather told her, "You know, you could be an engineer for a car company." Consumer reaction to Archer's work won't be far off, the SUVs slated to hit dealerships soon. Meanwhile, she's busy on something that could be just as intense as the console: Restoring a 1955 Packard Clipper in her garage. Head to Freep to check out the story of Archer and the console.

Recharge Wrap-up: U of M wins Solar Challenge, family attempts record-breaking e-bike ride

The University of Michigan Solar Car Team has won the 2014 American Solar Challenge. It is the team's eighth national championship, its fifth in a row, and its first using Siemens' product lifecycle management (PLM) software. The race took place over 1,722 miles and seven days traveling across eight states. The team's car, called "Quantum," outpaced the nearest competitor by four hours. Looking forward, Michigan Solar Car Project Manager Pavan Naik says, "The switch to Siemens tools will give us the ability to model and simulate everything and truly allow us to optimize the performance of our new vehicle. As we start on our quest to win the World Solar Challenge in 2015, we'll be leveraging a full complement of PLM solutions." Read more in the press release below. The EcoCar3 competition, in which teams will convert Chevrolet Camaros into hybrid electric cars, begins in September. The various college teams will have four years to lessen the car's environmental impact as much as possible while maintaining performance and, of course, that cool Camaro design. EcoCar3, which is put on by the US Department of Energy and General Motors, kicks off with a workshop in Novi, Michigan from September 16 - 18. Read more at the DOE website at the dedicated EcoCar3 site or watch the announcement video at our previous post. Zap and Jonway Auto are shifting to a high rate of EV production. Zap already has two lines creating the Urbee EV to met demand, and is switching over a third to make electric minivans and SUVs. The company aims to produce 30,000 EVs by 2015 for the Chinese market. Zap says it has a backlog of 25,000 Urbee orders. Read more in the press release below. A family of four hopes to make a world record-breaking, 6,000-mile electric bike journey this fall. The family, which recently drove from Argentina to Montana in a pickup with a camper, will ride from Montana to Maine, then down the East Coast to Florida in an attempt to break the record for longest electric bicycle ride. They'll use two bikes. The Father, Thomas, will ride one of the bikes carrying one of the children, while the rest of the family rides in a support vehicle, with the mother, Dylan, riding the second bike when they can find others to drive. They have started a crowdfunding campaign for some of the equipment needed to document the trip. See the video below or read more at Treehugger.
