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.

GM might share the Chevy Volt's powertrain tech with rivals

Car shoppers might eventually find the award-winning powertrain from the second-generation Chevrolet Volt under the hood of another automaker's vehicle – at least if General Motors global powertrain chief Dan Nicholson gets his way. According to Automotive News, Nicholson would be open to partnerships with other companies to share the range-extended setup. "We want to be the partner of choice in propulsion system development in this complex and turbulent era we are approaching," he told the trade publication. For an automaker that wants an electrified solution, the Volt's system would be an easy choice. It combines a 1.5-liter four-cylinder with two electric motors and an 18.4-kWh lithium-ion battery. The EPA estimates the setup is good for 106 MPGe combined and 53 miles of EV range in the Volt. Wards selected the powertrain for its 10 Best Engines list for 2016, and the Chevy won the Green Car of the Year Award. According to Automotive News, a partnership could have serious financial implications for GM and its collaborator. Rival automakers could get a competitive powertrain without the huge expense of research and development. Meanwhile, The General would benefit from larger economies of scale to drive down prices. Don't look for the Volt's powertrain to arrive in other vehicles too soon, though. GM spokesperson Kevin Kelley told Autoblog that he was "not aware of anything going on" in regards to negotiations with other automakers. In the meantime, we'll keep our eyes open for companies borrowing the Bowtie's advanced tech.

Nissan Leaf sells 1,553 in April, Volt climbs to 905

After three months in the 500 and 600 range, sales of the Chevy Volt climbed to 905 in April. That's up for the year so far – likely due to increasing discounts – but still down 41.5 percent from April 2014. As we've been saying every time the Volt turns in less-than-exciting monthly sales numbers, we suspect a large number of potential Volt buyers are waiting for the next-gen model to arrive in the second half of 2015. While the price for that car has not yet been announced, the updated tech specs show that it will probably be worth the wait for drivers who want the latest and greatest. Over on the Nissan Leaf side of things, April sales were 1,553 units this year. That's the second-best month of the year but down from the 2,088 units sold last April. After the Leaf finally climbed to the top of the cumulative best sellers list for plug-in vehicles last month, the difference between these two leaders is now 1,824 in favor of the Leaf. Nissan says that sales were influenced by the launch of its No Charge To Charge promotion in Indianapolis and Fresno, CA. This deal gives new Leaf buyers and lessees two years of no-cost quick charging in these markets. No Charge To Charge is not available in 15 US markets for (San Francisco, Sacramento, San Diego, Seattle, Portland, Nashville, Phoenix, Dallas-Ft. Worth, Houston, Washington, DC, Los Angeles, Chicago and Atlanta) and will expand to 10 more by the middle of this year. As we do every month, our full wrap-up of US green car sales is coming soon.
