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.

2014 Corvette Stingray meets Tesla Model S in drag strip showdown

They come from two different worlds and have little in common. The Tesla Model S P85 is the sportiest version of this paradigm-punching sedan from California, while the 2014 Corvette Stingray Z51 is a performance-enhanced version of Michigan's recently-updated sports car stalwart. The West Coast car seats five adults and eats electrons like Popeye eats spinach, the Easterner has two passenger places and, surprisingly, sips gasoline like one might bourbon. An attribute they do happen to share is extreme quickness. This similarity is all the excuse Drag Times needed to set the vehicles beside each other at the Palm Beach International Raceway for a bit of mano-a-mano quarter-mile combat. Fortunately enough, cameras were rolling for each of two bouts down the blacktop and the results recorded for our edification and enlightenment. The winner? We won't spoil it for you, but let's just say it's really, really close. How close? Scroll below and watch the video for yourself. Just be warned, the results may surprise you.

GM raises 2023 guidance on strong sales, higher profits

General Motors beat first-quarter profit estimates and raised its full-year earnings and cash-flow guidance after vehicle demand at the start of the year surpassed expectations. Its shares rose in premarket trading. GM made $2.21 a share in adjusted profit in the first quarter, compared to a consensus forecast of $1.72 a share. Revenue rose 11% to $39.99 billion, it said Tuesday, which was more than the $39.24 billion analysts expected. The stronger results stem from rising sales in the US, even in the face of higher interest rates and inflation. GM executives said demand was strong enough to revise 2023 guidance upward, boosting profit estimates for the year by $500 million to between $11 billion and $13 billion. “We did it with strong production and inventory discipline and consistent pricing,” GM Chief Financial Officer Paul Jacobson said on a call with journalists. “All in all, weÂ’re feeling confident about 2023.” The Detroit automaker raised per-share full-year guidance to between $6.35 and $7.35, up from $6 to $7 a share, and said free cash flow would also increase by $500 million to a range of $5.5 billion to $7.5 billion.  GMÂ’s shares pared a gain of as much as 4.4% before the start of regular trading Tuesday, rising 3.5% to $35.50 as of 6:55 a.m. in New York. The stock was up 1.9% for the year as of the close on Monday.  North American Strength The automakerÂ’s sales were particularly strong in North America, where first-quarter earnings rose before interest and taxes rose to $3.6 billion. Vehicle sales rose 18% to 707,000 in the region. Jacobson said the company originally expected to sell 15 million vehicles in the US this year, slightly less than the 15.5 million annualized rate automakers foresaw in the first quarter. North American demand was enough to offset a weak performance in China, GMÂ’s second-largest market. The automaker continues to struggle in the country, where its vehicle sales fell 25% to 462,000 vehicles in the quarter. Profits from its joint ventures in the market slumped 65% to $83 million.  The market has struggled overall in the wake of Covid-19 restrictions and foreign automakers have had to overcome a growing preference for Chinese brands by competing on price, squeezing profit margins. The situation in China probably wonÂ’t significantly improve until the second half of the year, according to Jacobson. GM remains on target to sell 150,000 electric vehicles this year, the CFO said.
