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.

Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.

These are the five most ridiculous attacks on the Chevy Volt [w/videos]

It's been a long, strange trip for the Chevy Volt from the time when the now-odd-looking concept version (above) was introduced at the 2007 Detroit Auto Show to today. And now, General Motors announced that the second-generation Chevy Volt will make an appearance at the 2015 Detroit show in January. This debut represents a victory for GM with what has easily become the most politicized car of the 21st Century. There are plenty of reasons for someone to criticize the Volt, but what's amazing is just how much anti-Volt energy has been spent not on things like the styling or how the EREV setup is not as efficient as a pure-EV powertrain. As we wait for more official information on the new Volt, we thought it would be fun to go back and look at some of the most wildly incorrect reporting and strangest attacks on the Volt from the archives. There is so much good stuff out there, it was hard to pare the list down, but these are our five favorites. Amazingly, they're not all clips from Fox News. Check 'em out below. 5. GM Is Going To Stop Making The Chevy Volt In The US Do you remember when GM was about to move Volt production to China? Well, yeah, this was reported back in early 2012 when a GM executive mentioned that the automaker would get benefits of building the Volt in the places where it sells them. This was spun into a story of GM taking Obama bailout money and then running to China. The Blaze was not happy: "Given the fact that Federal government helped itself to millions and millions of taxpayer dollars under the pretense that it was going to combat high unemployment by creating 'green jobs,' it would seem that moving research and development (and possibly manufacturing) overseas is slightly, well, counterproductive." Well, of course, that never happened. There's no way to say that GM will never build a version of the Volt in China, but the news we hear rumors of these days is that GM is going to move production of more Volt parts (specifically, the motors) to Michigan from overseas. 4. The Chevy Volt Is A Fire Trap There has never been a Volt that just spontaneously lit up while driving down the road. Yes, there were Volts that caught on fire. Yes, that's a scary thing. But there has never been a Volt that just spontaneously lit up while driving down the road. These were crashed test vehicles with destroyed batteries and plugged-in vehicles that were not the cause.
