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.

Next Corvette ZR1 to get 700 horsepower?

Word has it General Motors may offer as much as 700 horsepower in the C7 Corvette ZR1. Motor Trend reports the next Corvette Z06 will continue to rely on its naturally aspirated 7.0-liter V8 engine for thrust, but the lump will deliver substantially more power. How much more? MT says the engine could deliver up to 600 ponies. That's a jump of 95 horsepower over the current Z06, though no figures have been finalized as of yet. Right now, GM is reportedly waiting to see what sort of grunt it can glean from the next ZR1.
The automaker has already made it clear it will resurrect the LT5 name for the new supercharged V8, and if GM is already pulling 600 from the Z06, the big dog ZR1 would theoretically offer 700 horsepower. Either way, the range-topping Corvette will be suitably insulated from its less potent siblings. Stay tuned. We aren't likely to see the Z06 for at least a year, with the ZR1 trailing along at some point there after.

Farley reacts as UAW expands strike against Ford, GM

Members of the United Auto Worker union walk out of the Chicago Ford Assembly Plant as Lance Williams from Lansing, Ill., waves the UAW flag Friday. (AP)   As the United Auto Workers walk off the job at an additional Ford and General Motors plant, Ford CEO Jim Farley addressed investors and members of the media Friday, pleading the case for the company's latest overture to the union and addressing both public and investor concerns regarding the core issues facing American manufacturing.  Farley made a public case for Ford's efforts to resolve the dispute, expressing frustration with the ongoing stalemate and noting both the concessions Ford offered before the strike began and the signing of a contract with Canada's Unifor. Farley also acknowledged UAW President Shawn Fain's success in getting the union's message out, quipping: "Shawn has been on TV more than Jake from State Farm at this point." The first-ever simultaneous strike against the Detroit Three automakers enters its third week with threats of continued expansion, but little in the way of obvious concrete progress.  "If the UAW’s goal is a record contract, they have already achieved this," Farley said. "It is grossly irresponsible to escalate these strikes and hurt thousands of families." Farley also lamented the fact that EVs have become the subject of partisan conflict, with the company's recently announced battery production facilities taking heat from both pundits and investors as Ford was forced to press pause on the venture while negotiations continue. Former President Donald Trump dropped in to Michigan this week to declare EVs the enemy of blue-collar jobs. "They've become a political football, and that's a shame," he said. Friday saw an expansion of the UAW strike to Ford's Chicago assembly plant and GM's Lansing, Delta Township, Michigan, assembly plant, covering about 7,000 workers, Fain said in an announcement, bringing the total number of workers on the picket lines to 25,000. The strike will not include any additional members at Stellantis, where talks have reportedly been more productive. The Ford and GM plants went on strike at noon Eastern today (Friday). Ford builds the Explorer and Lincoln Aviator in Chicago. GM's Delta Township plant builds Chevy Traverse and Buick Enclave. "Despite our willingness to bargain, Ford and GM have refused to make meaningful progress," Fain said in a video address Friday morning.
