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.

EcoCar3 will convert Camaro to bitchin' eco rides

In the 47-year-history of the Chevrolet Camaro, there have been countless college-age kids spending a ton of time getting under the hood and souping 'em up. Now, General Motors is adding a twist to the concept by donating 16 Camaros for the EcoCar challenge that puts university teams together to wring out better fuel-efficiency out of various vehicles. No word on whether there will be donuts on anyone's lawn, as suggested by 80's punks the Dead Milkmen, but the idea's never a bad one. EcoCar3 will feature 16 teams such as Arizona State, Penn State, Ontario's University of Waterloo and, of course, Detroit's Wayne State University. They'll spend the next four years "[reducing] environmental impact, while maintaining the muscle and performance expected from this iconic American car," as the EcoCar organizers say. The goal is to maintain body design and safety standards while boosting efficiency and lowering emissions, but the actual process is far more complicated than that description suggests. The California Air Resources Board (CARB) and Bosch are among the sponsors of the contest, which is also put on by the US Department of Energy and managed by Argonne National Laboratory. Penn State won Year Two of the three-year EcoCar 2 competition with its E85 plug-in hybrid electric vehicle converted out of a Chevy Malibu. The grand-prize winner of EcoCar2 will be announced in June. Check out the EcoCar3 website and see the announcement video below for more details. This content is hosted by a third party.

Drivers buy new $300K McLaren 720S, 2019 Chevy Corvette, and wreck 'em

Two high-powered, high-priced sports cars, wrecked in their infancies. No doubt they were fun while they lasted. In Great Falls, Va., a tony suburb of Washington, D.C., that hugs the Potomac River, someone was out enjoying driving the McLaren 720S they had purchased only the day before on a leafy, two-lane road. Then, horror: In an instant, the car hit a tree, mangled and destroyed "because of speed," according to the Fairfax County Police Department. Purchased Friday. Totaled Saturday. This McLaren 720S, costing around $300,000, was destroyed today in Great Falls because of speed. The driver was taken to the hospital with thankfully only non-life threatening injuries. A reminder to slow down, or it could cost you. pic.twitter.com/XhC3LKRY1t — Fairfax County Police (@FairfaxCountyPD) July 14, 2018 Then on salvage auction site Copart, a brand-new orange 2019 Chevrolet Corvette Grand Sport lies in a warehouse in Lincoln, Neb., its front left corner crushed, wheel askew. It had just 15 miles on the odometer. We know nothing of the backstory, except for the obvious front-end damage and secondary damage to the undercarriage. The rear end and 6.2-liter V8 engine, which makes 460 horsepower and 465 pound-feet of torque, look OK. The most current bid as this was published was just north of $9,000. It's tempting in both cases to assign the blame to over-eager drivers who weren't quite yet able to corral all that power. In the case of the McLaren, the supercar makes 710 horsepower and 568 pound-feet of torque from its quad-cam, twin-turbo 4.0-liter V8. It goes from 0-62 miles per hour in 2.9 seconds and boasts a top speed of 212 mph. We're not saying the unidentified driver was a newbie, but this car is definitely not for newbies. Police write that the incident is "A reminder to slow down, or it could cost you." As in, $300,000. Or at least the depreciation for driving it off the lot. Related Video:
