Watch a 2015 Corvette Z06 run the quarter in 11.7 seconds

We're not writing about this because it's an amazing run, we're writing about it because it appears to be the first run. Someone took a 2015 Corvette Z06 to Royal Purple Raceway in Baytown, Texas and blasted it down through the quarter mile. It's still wearing the dealer number in wax pen on the windshield and dealer plates, so this example is fresh from the mold. It's also a seven-speed manual. General Motors said the row-your-own Z06 can do the 'strip in 11.2 seconds, and they undoubtedly had a professional driver and more than one run to set that time. To have Just Some Guy show up at the raceway and do an 11.7 at 120.54 mph on his first run means we expect good things to come as Z06s get delivered to their owners. Check out the run in the video.

'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).

2015 Chevy Colorado gets its GearOn before Chicago

Complementing the Chevrolet Silverado Midnight Edition at the 2015 Chicago Auto Show is this, the 2015 Colorado GearOn Edition, which as the name might suggest, takes full advantage of the company's truck accessory catalog. Available on the volume LT trim and in both crew and extended cab varieties and with both the short and long-bed options, the GearOn Edition adds plenty of nifty extras designed to increase the truck's versatility and help accommodate bikes, kayaks and other outdoorsy items. The GearOn bars package, divider package and tie-down rings are supplemented an "EZ" lift and lower tailgate, side steps, gloss black 18-inch wheels, a body color grille, and blacked-out Chevy badges. And although it's not specifically called out in the attached press release, the paint on this special edition looks different than anything else in the truck's catalog. We dig it, especially with the black accents. Prices, meanwhile, start at $31,250, which is not even $1,200 more than a Colorado Extended Cab LT 4x4. We'll have more on the Colorado GearOn when it makes its debut later this week at the 2015 Chicago Auto Show, including live images to add to the pair of stocks distributed by Chevy. Until then, scroll down for the press release on the limited-edition truck.
