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.

AWD turbodiesel Equinox, Terrain dropped for 2020

Citing low demand, General Motors is dropping the AWD diesel options off the Chevrolet Equinox and GMC Terrain roster. Chevrolet spokesman Kevin Kelly confirmed to CarsDirect that for 2020, the diesel versions of these SUVs will only be offered with front-wheel-drive. CarsDirect notes that with the AWD diesel Equinox and Terrain gone, the only AWD diesel option in this class is the Mazda CX-5 Skyactiv diesel, which is significantly more expensive: As the AWD diesel CX-5 is only available in a fully loaded Signature specification, the $42,045 price tag is almost $10k heftier than the cheapest comparable Equinox, the AWD 1.6-liter diesel LT which starts from $32,495. The 2019 GMC Terrain AWD SLE costs $34,795 in comparison, which works out to being around $7,200 cheaper than the Mazda. The higher trim levels for the Equinox and Terrain are Premier and SLT, respectively. Some reasoning behind the AWD diesel GM SUV's low uptake is their own price difference to base FWD gasoline models: you can get a 1.5-liter Equinox for less than §25,000 listed. While the 2.2-liter Mazda has plenty more power at 168 hp and 290 lb-ft, compared to 137hp and 240 lb-ft in the 1.6-liter GM SUVs, the Equinox and Terrain are notably more frugal – they are rated 32mpg combined, while the Mazda can manage 28 mpg. With better fuel economy and a significantly lower list price, the General Motors twins are at least more wallet-friendly when it comes to numbers, and as the vehicles will cease to be built in that configuration there's likely to be some cash on the hood on ones in stock.

Ford Police Interceptors dominate Michigan State Police testing

Once again, Ford Motor Company builds the fastest police vehicles. The Blue Oval touted the news in an official release following Michigan State Police and Los Angeles County Sheriff's Department testing. Ford did very well. Except for one acceleration metric – zero to 10 miles per hour – the Blue Oval's Taurus and Explorer-based cop cars were the quickest, with particular praise coming for the EcoBoost-powered models, which bested Chevrolet and Dodge's V8-powered variants. Dearborn's products also posted the fastest average times around MSP's vehicle dynamics course. But it wasn't all positive for Ford. The only four-cylinder in the contest, the 2.0-liter, EcoBoost Ford SSP Sedan, had both the lowest top speed, 120 mph, and the slowest acceleration figures. It was also the slowest in track testing. Ford's products also failed to match the braking and top speeds of its rivals from Detroit and Auburn Hills – the rear-drive Charger Pursuit posted the best braking stats of the entire test, while the V8-powered Chevrolet Caprice hit the highest top speed, at 155 mph. Ford did score a top speed award, among SUVs, but at 132 mph, the naturally aspirated Police Interceptor Utility had to share its award with the equally fast, rear-drive Chevrolet Tahoe. The LA County Sheriff's timing isn't publicly available, but according to Ford, the EcoBoost-powered police cars put on a similarly impressive show for cops on the West Coast. We've assembled a spreadsheet on Google Docs that offers an easy to browse comparison of the different stats assembled by the Michigan State Police, and divided the vehicles between standard V6-powered sedans, high-performance sedans (EcoBoost and V8 models), and SUVs.
