2021 Chevy Colorado and GMC Canyon facelift spied

The Chevy Colorado and its GMC Canyon twin have been on sale for a good long time now, and while things move a little more slowly on the truck side when it comes to facelifts and model changeovers, it seems like it’s about time. So itÂ’s no surprise to see some lightly camouflaged trucks running around ahead of what appears to be a minor refresh for the 2021 model year. Starting with the Colorado, it appears to have a bowtie hiding behind some camo in the center of the grille, which otherwise looks like the no-bowtie option you can get on 2019-and-up trucks. It could be that Chevy is keeping the no-bowtie grille design but allowing a bowtie to grace it, or it could be misdirection. Either way, the grille pattern adds a bit of flair to the otherwise staid front end design. There also appears to be a bit more shape to the lower air inlet, with echoes of some of the lower fascias of its bigger Silverado stablemate. The Canyon, on the other hand, shows more extensive front-end changes. At first glance, it looks to emulate some variants of the GMC Sierra, which would make sense given those modelsÂ’ changes for the 2020 model year. In particular, this Canyon has hints of Sierra HD, being more square and monolithic than the regular Sierra 1500s, although itÂ’s a little hard to tell with the camo covering the edges of the grille. It could certainly also adopt more rounded corners like the 1500s. Either way, itÂ’s more vertical and thereÂ’s less differentiation between the upper grille and lower opening. ThereÂ’s nothing in the way of changes around the sides or back, and while there may be some minor changes inside, we arenÂ’t expecting any. The word around town is that this isnÂ’t a full facelift, but rather a minor front end tweak thatÂ’ll just be a regular part of the model-year changeover. 

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

2016 Chevy COPO Camaro wears drag to SEMA [w/video]

Attendees to this year's SEMA Show get to be the first to check out Chevrolet's latest COPO Camaro that's now based on the new, sixth-generation model. As before, they packs a bevy of racing modifications to rocket down drag strips across the country. All of the interested customers might not get one of these hand-built machines, though, because Chevy is sticking with the tradition of only building 69 of them for 2016. Devised to compete NHRA Stock and Super Stock Eliminator classes, the latest COPO Camaro features the lighter, more rigid platform of the sixth-gen model. Buyers can choose from an array of V8s for power, including a supercharged 350-cubic-inch engine, a naturally aspirated 427, or an LT-based 376. All of them come with a race-prepped Turbo 400 three-speed automatic, solid rear axle, and adjustable suspension. The COPO on display for SEMA wears custom styling from drag racer Courtney Force that combines a Red Hot and black color scheme with her name slashing across rear fender. This one also packs a concept 350-cubic-inch V8 with a 2.9-liter Whipple supercharger. If you're interested in owning it, the car will cross the auction block at a Barrett-Jackson sale in 2016, and the proceeds will go to the United Way.

After visiting the COPO build center, Force collaborated with Chevrolet designers to create a custom appearance for the 2016 COPO Camaro SEMA show car. It will be auctioned at a Barrett-Jackson sale in 2016, with the proceeds going to United Way. Chevrolet will build 69 COPO Camaro race cars for 2016, extending the production legacy that began in 2012 with the fifth-generation Camaro. Like the previous editions, the new COPO Camaro is designed for NHRA's Stock and Super Stock Eliminator classes. "With the new Gen Six Camaro as its foundation, the 2016 COPO Camaro begins the next chapter of an historic racing legacy," said Jim Campbell, Chevrolet U.S. vice president of Performance Vehicles and Motorsports. "It's great to have Courtney Force on Team Chevy and to work with her on the design of the new COPO Camaro show car.
