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.

Can Fernando Alonso win Indy? Here's why and why maybe not

SPEEDWAY, IN – The month of May has been a joy ride for Fernando Alonso at Indianapolis Motor Speedway. The two-time Formula 1 champion came to Indy having never turned left in a race car without also turning right. But he acquired such a feel for Indy's 2 1/2 -mile rectangle during a month of practice and qualifying that he's considered a strong contender to win the 101st Indianapolis 500 on Sunday, rookie or not. "You're not trying to bring somebody on who has very little experience driving very high-performance cars," said 2003 Indy 500 winner Gil deFerran, who this month has helped Alonso learn the nuances that make the speedway such a tough place to conquer. "I suppose it would be a little bit different if you were dealing with a younger, much less experienced person." Driving a McLaren Honda from the potent Andretti Autosport team, Alonso was consistently near the top of the speed charts in practice, he qualified fifth fastest at 231.300 mph, and he handled runs in heavy traffic like a driver who'd done it many times before. But those were the prelims. The race is another creature. "The car felt the best (it has) in the last two weeks. I was making some moves, taking some different lines. I am extremely happy." Other drivers say the speedway looks different on race day when the crowd, expected to top 300,000, fills the grandstands and makes an already narrow track seem even tighter. The three-wide rolling start is something Alonso has never experienced, and he will see the green flag from the middle of the second row between Takuma Sato and J.R. Hildebrand. And the space he'll be given by his competitors in the first 180 laps may disappear In the last 20 when it's every driver for themselves. Can a rookie like Alonso win this race? Absolutely, as Andretti driver Alexander Rossi showed last year when his team used a fuel-mileage strategy to win in his first taste of Indy. We're talking about Fernando Alonso here, who easily could show his rookie stripes to the rest of the field most of the day. His best lap in Friday's final practice, 226.608, was fifth fastest in the field and, more important, he said the car felt comfortable in heavy traffic. "The car felt the best (it has) in the last two weeks," Alonso said. "I was making some moves, taking some different lines.
