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.

Chevy monitors drivers' biometrics while experiencing new Corvette Stingray

We tell you about what a car is like to drive every day, remarking on throttle response, steering weight and feedback, squat, dive, brake fade and a dozen or more other factors of performance. What we can't tell you, though, is what the car does to us - how its performance impacts us, physically. That's what makes this video series from Chevrolet so darn cool.
The Bow-Tie brand rented out Spring Mountain Motorsports Ranch, got several (very) different individuals together, strapped a bunch of sensors to their bodies to record biometric data ranging from heart rate to respiration to brain activity, and then handed them keys to the new Chevrolet Corvette Stingray. The results are explained in a series of videos, devoted to each driver, showing how different people react to the Corvette's performance.
If, like your author, you're a nerd for medical science, this is going to be a fascinating set of videos. If not, it's still pretty cool to see how the body of someone with racing experience, like Gran Turismo creator Kazunori Yamauchi, reacts to tracking a car like the Corvette Stingray compared to the owner of legendary Detroit barbecue joint, Slows BBQ. Take a look below for all six videos from the series, or hop over to the Corvette Vimeo channel for the interactive experience, where you can see all the different metrics.

GM recalling 1.4 million older vehicles for oil leak fire risk

General Motors is recalling 1,411,332 older vehicles with its 3.8-liter V6 yet again due to a fire risk. Specifically, there are 1,283,340 of them in the US, and the affected models are the: 1997-2004 Pontiac Grand Prix 2000-2004 Chevrolet Impala 1998-1999 Chevrolet Lumina 1998-2004 Chevrolet Monte Carlo 1998-1999 Oldsmobile Intrigue 1997- 2004 Buick Regal The fault with these vehicles is that oil can drip onto the hot exhaust manifold during hard braking, which can potentially cause of fire. In the last six years, there have 19 reported minor injuries from this problem but no crashes or fatalities, according to the company. Spokesperson Alan Adler also told Autoblog: "GM has reports of 1,345 fires in vehicles that were repaired under two previous recalls for this issue." At this time, GM is still developing a remedy for the problem. According to Adler, the company advised owners to park these vehicles outside for the previous recalls. "The cars can be safely driven. In cases where a customer reported an engine fire while driving, smoke was reported, which would be an indication of a malfunction," he said. This is GM's fourth recall for this problem since 2008, according to The Detroit News. At one point it was believed that aging valve cover gaskets allowed the oil to leak out and drip onto the manifold. A campaign in 2009 covered nearly 1.5 million of these models through the 2003 model year for the same issue. At the time, dealers installed new spark plug wire retainers as a fix.

GM is working on a remedy. The company is aware of post-repair fires in some vehicles but no crashes or fatalities. There have been 19 reported minor injuries over the last six years. These vehicles with 3.8-liter V6 3800 engines are affected: 1997-2004 Pontiac Grand Prix, 2000-2004 Chevrolet Impala, 1998-1999 Chevrolet Lumina and 1998-2004 Chevrolet Monte Carlo, 1998-1999 Oldsmobile Intrigue and 1997-2004 Buick Regal.
