First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.

Chevy Silverado HD gets the Custom Sport treatment

Everyone remember the Silverado 1500 Custom Sport Chevrolet showed at the 2015 Detroit Auto Show? Good. Now, the company has applied the same styling treatment to its heavy-duty pickups, introducing the 2500 and 3500 Custom Sports. The two trucks appeared today at the 2015 Denver Auto Show. A monochromatic look is the order of the day, with the heavy-duty Silverados getting body colored bumpers both fore and aft as well as a body color grille. Chrome accents sit in said grille, while the shiny finish can also be found on the door handles and mirrors. Buyers of the 2500 Custom Sport will get five-spoke, 20-inch, polished wheels, while the brawnier 3500 gets 18-inch polished hoops as standard (dualies are downgraded to 17-inchers). Custom Sport models are only available in Summit White or Black. The trim package can be added to both LT and LTZ models, with a price premium ranging from $700 to $1,695, depending on the truck.

2022 Chevy Silverado HD gains Multi-Flex tailgate as an option

GM is spreading the Multi-Pro Tailgate love around its truck lineup, and the Silverado HD is the latest pickup to gain the option. Just like the 2021 Silverado 1500, Chevy uses the “Multi-Flex” name for it in the HD, eschewing GMCÂ’s “Multi-Pro” branding for the bowtie vehicles. YouÂ’ll be able to option the tailgate on 2022 model year Silverado 2500HD and 3500HD models. ItÂ’ll be available optionally in every trim, so thereÂ’s no need to grab a more expensive trim to gain access to the trick tailgate — youÂ’re also not required to take it in higher trims. Functionality is the same as the standard Silverado and Sierra.  The primary gate opens and closes like any other tailgate out there. ThereÂ’s a primary gate load stopper that allows you to put the gate down and still keep things from flying out the back (it can also be arranged such that the load stopper is at a higher height by using the inner gateÂ’s stopper). The inner gate folds down perpendicular to the ground to allow closer access to the bed. A full-width step is available if you fold both “gates” down and pop out the inner panel. And lastly, the inner gate can be lowered to use it as a small work space. You can watch the short video above to get a quick run through of all the positions, or scroll through the gallery at the top of this post. Besides the tailgate, Chevy says the 2022 Silverado HD is gaining a new Greenstone Metallic exterior paint color. Other changes for 2022 were not detailed at this time, but Chevy says the trucks with this tailgate should be available sometime this summer. Related video:
