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.

Motor Trend puts Chevy Camaro Z28 and Porsche 911 GT3 Head 2 Head

Motor Trend admits, "This is an unfair comparison." But that doesn't make it any less fun to watch when they pit a Camaro Z/28 against the Porsche 911 GT3. The former has a 7.0-liter V8 with 505 horsepower and 481 pound-feet of torque shifted through a six-speed manual. The latter has a 3.8-liter flat-six with 475 hp and 324 lb-ft shifted through a seven-speed dual-clutch transmission. Yet those are only the little disparities – the big disparities are mass and money: the Camaro weighs 3,882 pounds and costs $76,150 as-tested, the Porsche weighs 3,267 pounds and costs $145,785. But they're both about hardcore performance, so MT takes them out on the street, to the drag strip, to the parking lot for figure eights and a skidpad test, and finally to Big Willow for Randy Pobst to give his professional assessment. Remember when a lotta people spent a lotta time debating Pirates vs. Ninjas? This is like that, only it's the "haul-ass good-time car" vs. the "track surgeon." Enjoy the debate in the video.

2019 Toyota Corolla vs. compact hatchbacks: How they compare

So you've read what we thought about the 2019 Toyota Corolla Hatchback. Oh, you didn't? Well, click to your left, we'll still be here. Just made some coffee, we're good for a while. Welcome back! Wasn't that riveting? The blue paint sure is bright, eh? Well, now you must be wondering how that new 2019 Corolla stacks up with all the other hatchbacks. And, despite long thinking that hatchbacks were doomed, there are actually quite a lot of them these days. So many, in fact, that we couldn't fit them all in our space-limited comparison chart. So, with apologies to the Hyundai Elantra GT, Kia Forte and the dead-man-walking Ford Focus, these were the cars we chose based on sales and competitiveness: the Honda Civic Hatchback, Mazda3 5-Door, Volkswagen Golf, Chevrolet Cruze and Subaru Impreza. We also included the outgoing Corolla iM for reference. If you think we've left something of interest out, you can always create your own comparison. Performance and fuel economy There is but one king here, and its name is Civic. While the sedan and coupe come with a naturally aspirated 2.0-liter 158-horsepower four-cylinder that's less potent than the Corolla's, the hatchback comes standard with the 1.5-liter turbo that aces the segment in terms of both acceleration and fuel economy. The Golf's acceleration should be comparable, but as you can see, it trails on fuel economy (still not bad, though). The new Corolla ends up being better than the rest with its new 168-hp four-cylinder paired to novel transmissions: a six-speed manual with rev-matched downshifting (!) and a CVT that mimics the actions of a 10-speed automatic. The Corolla does weigh more than everything else, though, so that could hamper its acceleration. Fuel economy data also wasn't announced, but Toyota indicated it would be a bit better than the old Corolla iM. Something akin to the 2.0-liter Mazda 3's numbers seems likely. As for the Mazda, its top two trim levels actually come standard with its bigger engine. In any event, despite its ample power, testing has often showed that the Civic is still the quicker car from 0 to 60 mph. And finally, let's not leave out the two on the end. The Subaru is the only car in the segment that offers all-wheel drive (the Focus RS and Golf R don't count), but is also the segment weakling now that the Corolla iM has been discontinued.
