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.

2017 Chevy Bolt Prototype Quick Spin [w/video]

To say that there's a lot riding on the upcoming Chevy Bolt doesn't quite get at how important this all-electric vehicle could be for GM. To say that there's a lot riding on the upcoming Chevy Bolt doesn't quite get at how important this all-electric vehicle could be for GM. We are entering a new phase for EVs in the US, and it's one where there will be more than one 200+ mile range electric model that will cost around $30,000-$35,000. The two obvious first entries are the Tesla Model 3 and the Bolt, but you can bet your Level 2 charger that Nissan will be joining the party as well, along with all sorts of as-yet-unannounced entries from other automakers. The main change that all of these longer-range EVs will bring is – potentially – to make plugging in your car a mainstream thing. And if the mainstream is in play, then there's money to be made, and you're going to need one heck of an EV to get people to pick your car instead of someone else's. So, yeah, the Chevy Bolt could be a big deal. And today we not only got a bit more information about the car but we also got to go on a really short test drive in a prototype version outside of the Las Vegas Convention Center as part of CES 2016. The "drive" took place in a closed-off parking lot and my two laps through the cone course took less than three minutes, but I can still say that it looks like GM will be bringing a solid option to the marketplace soon. Chevy Bolt Prototype front 3/4 View 16 Photos If you shift into L, the regen becomes wonderfully strong. One of the pleasant surprises in the Bolt prototype is the ability to drive with just one pedal. When in D, the Bolt coasts a bit, which is nice for highway driving, but if you shift into L, the regen becomes wonderfully strong. Strong enough that you don't need to engage the brakes at all if you're in standard city traffic, with lots of gentle stops and starts. If you want even more stopping power without getting the brakes involved, the Bolt also has the regen-on-demand feature that was introduced in the Cadillac ELR and works great in the second-gen Chevy Volt. When you pull the paddle on the left back side of the steering wheel, the electric motor instantly becomes a generator and the Bolt turns forward momentum into energy for the battery pack. It will even bring the car to a complete stop and then hold it when you release the paddle.
