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.

New Chevrolet Silverado to be revealed on Facebook on Thursday

There's not much to see here, but if you're one of those waiting for the reveal of the 2014 Chevrolet Silverado 1500, above is the teaser image that Chevrolet posted on its Facebook page. We've seen the truck in form-fitting camo before, and even less can be made out here beyond those seriously punchy Silverado-esque fenders and the knowledge that the projector-beam headlamps teased previously do indeed work. We'll have to wait until Thursday for a full perusal of the "bold exterior design" and "careful attention given to every detail" we've been promised.
Gathering intel and rumors, magnesium and aluminum contribute to the Silverado's weight loss plan, the purported "High Country" top-tier trim will contribute to luxury pickup truck competition and profit margins and the next-generation small-block V8 will contribute to improved fuel economy. On the engine note, there have been rumors of available V6 engines, and when Facebook user John Jones asked "Where's your answer to that EcoBoost Chevy?", the Bowtie replied "stay tuned on the 13th. We think you'll be pleased...".
Along with the "Raise the Bar" tag, Chevrolet says of the Silverado, "You asked, we delivered." You can watch the reveal live on Chevrolet's Facebook page at 9:30 am EST, this Thursday, December 13. The GMC Sierra 1500 will also be there, and we'll see both in person at the Detroit Auto Show in January.

GM and Ford quarterly sales continue to slump in China

BEIJING — General Motors and Ford announced their quarterly sales in China fell, albeit at a slower pace sequentially, as the U.S. automakers were hit by a slowing economy amid the Sino-U.S. trade war. GM's vehicle sales in China for the quarter ended June 30 dropped 12.2%, while Ford's sales slumped by 21.7%. While GM also suffered from heightened competition in its key mid-priced SUV segment, Ford was hurt by the limited new models for customers to choose from. For the first quarter of this year, Ford's sales in China tumbled 35.8 percent while GM's skid 17.5 percent. Still, the numbers from GM, the second biggest international automaker in China by sales, and Ford portend more uncertainty for the industry which is trying to rebound from a downward spiral that led to its first annual sales decline last year in more than two decades. GM delivered 1.57 million vehicles in China in the January-June period this year, while Ford delivered 290,321 vehicles. China's factory activity shrank more than expected in June, highlighting the need for more economic stimulus amid higher U.S. tariffs and weaker domestic demand. Annual car sales in China fell last year for the first time since the 1990s, and they are expected to fall this year too. Sales tumbled 16.4% in May from the same month a year prior, the China Association of Automobile Manufacturers (CAAM) said. That marked the 11th consecutive month of decline and followed falls of 14.6% in April and 5.2% in March. U.S. car companies' share of total China passenger vehicles sales fell to 9.6% in the first five months of this year from 10.9% in the year-ago period, according to CAAM. Over the same period, German car makers' share has risen to 23.3% from 20.9% and Japanese auto makers' to 21.3% from 17.3%. CAAM is set to announce June sales next week, which industry analysts forecast will be negative.   New models In China, GM has a joint venture with SAIC Motor Corp, in which the Buick, Chevrolet and Cadillac are made. It also has another venture, with SAIC and GuangxiAutomobile Group, in which they make no-frills minivans and have started to make higher-end cars. Sales of GM's affordable brand Baojun dropped 31.8% for the latest quarter. But luxury brand Cadillac's sales jumped 36.6%. GM sold 3.64 million units in China last year, down from 4.04 units in 2017. Ford makes cars in China through its joint venture with Chongqing Changan Automobile Co and Jiangling Motors Corp (JMC).
