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.

Hagerty kicks back with Ringbrothers for a look at the Recoil

Over the years, Ringbrothers has shown the ability to mix a meticulous eye for style and serious amounts of horsepower with customs like the Pantera-based Adrnln. The company's recent project, a tuned 1966 Chevrolet Chevelle called Recoil, is some of its best work yet and already has Jay Leno's denim-clad stamp of approval. Now, Hagerty is taking a look, while digging into the history of the actual Ring brothers: Mike and Jim. The two guys grew up in a small town where owning a car was practically a necessity, and the brothers were already wrenching before they could even legally drive. Eventually, that passion grew into a business, which led to wonderfully customized performance vehicles like the Recoil. Hagerty gets a fascinating look into Ringbrothers tuning philosophy in its interview. Of course, the real interest lies in this custom Chevelle, and there's a chance to hear the absolutely ferocious sound from the Recoil's supercharged V8 in this clip.

Chevy Bolt name just might get through US trademark office

UPDATE: GM told AutoblogGreen on June 1 that, "Our Chevrolet Legal team has been working closely with the USPT on the Chevrolet Bolt trademark. As of last week, our legal staff received consent from Yamaha to use the Bolt name. According to our legal team, our USPT application is back to active status." Also, it appears that GM has further trademarked Bolt EV and Chevrolet Bolt EV. Chevy wants to sell a 200-mile electric vehicle for around $35,000 in a few years. The Detroit automaker wants to call that car the Bolt, not to be confused with the company's other plug-in, the Chevy Volt. Unless something changes, the United States Patent and Trademark Office (USPTO) is going to crush GM's Bolt-flavored dreams. The USPTO has suspended GM's trademark application. The USPTO said in its suspension that there was a "likelihood of confusion" with another Bolt trademark, No. 4429759, which applies to a Bolt trademark filed by Yamaha on August 09, 2012. That's well before GM's effort to trademark the Bolt name in 2014. GM's application will remain suspended, the USPTO said, "until the earlier-filed referenced application(s) is either registered or abandoned." Maybe GM will use this setback to respond to the many criticisms of the Bolt name we've heard since it was first announced. There is another page on the USPTO's website that says GM's Bolt application is still live, but we assume that just hasn't been updated yet. Related Video:
