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.

Performance cars overpower the Detroit Auto Show

At precisely the stroke of noon on Monday, the 2016 Acura NSX rolled on stage at the Detroit Auto Show amid plumes of smoke and dancing lights. The sounds of the powerful engine revving soared to the rafters. It was the second coming of Acura's iconic sports car, and the reveal had all of the expected trappings. Afterwards, champagne corks popped and the bubbly flowed. It was noon in Detroit, but for the green-car movement, it seemed like the clock had struck midnight. That's an exaggeration, but performance was the overwhelming theme of North America's most important show. Ford – which has helped lead the way in smaller displacement engines and early adoption of hybrid powertrains – had more than 1,500 horsepower on stage one point after it revealed the GT concept, the new F-150 Raptor and the Shelby Mustang GT350R. The NSX is technically a hybrid (it has three electric motors), but with 550-plus hp, there's no doubt this Acura was bred on the track. The theme continued throughout the show at nearly every stand. Alfa Romeo showed off the 4C Spider, which is the open-air version of a car that purports to be the spiritual successor of the high-performance 33 Stradale from 1967. On Tuesday, Cadillac is scheduled to reveal the 640-hp CTS-V with the V8 transplanted from the Corvette Z06, and the Lexus was expected to roll out its own V8-powered beast, the 467-hp GS F. For enthusiasts – especially enthusiasts with money – these are halcyon days. But make no mistake, all of this power has a purpose. Ford product chief Raj Nair said the Blue Oval uses high performance cars to develop technologies, like aerodynamics and materials, which are then shared across its lineup. "It's another proof point about how serious we are in developing innovation through performance," he said. Ford, which is rolling out at least 12 performance cars by 2020, said the sporty cars attract younger and more influential buyers to its fold, which can help burnish its image beyond adding sales volume. Toyota is taking a similar approach, senior vice president Bob Carter said, noting the Lexus RC coupe draws people into showrooms and gets them excited about the brand, even if they don't end up buying one. "They provide an aspiration and a halo that provides the attention that gets you noticed in a cluttered market," he said.

2019 Hyundai Kona Electric First Drive Review | No compromises

The results of last week's United Nations climate study reveal that Earth's climate situation is much more dire than previously thought. Unless we do something drastic to stop pumping carbon emissions into our atmosphere, we'll do irreversible damage by 2030. It seems almost prophetic, then, that Hyundai is launching two vehicles — the hydrogen-powered Nexo FCV and an all-electric variant of the recently launched Kona crossover. The more compelling of the two is the Hyundai Kona Electric. It joins other purely battery-powered machines such as the Nissan Leaf, the Chevy Bolt and the Tesla Model 3, but the Korean automaker one-ups the competition by arriving in the form of a crossover. Americans can't get enough of them, and no other pure electric on the market offers it unless you're talking about the $83,000 Tesla Model X. The Kona EV's next closest competitor is the boxy electric Soul, and in case you didn't know, Kia's affiliate company is none other than Hyundai. In truth, the crossover moniker isn't entirely accurate. Like its internal-combustion-engined counterpart, the Kona EV doesn't really sit above regular car height. Rather than call it a compact crossover, it'd be more appropriate to label it a hatchback with some rugged-looking body cladding. The Kona Electric does, however, top nearly all of its EV rivals for cargo space, with 19.2 cubic feet. Only the Leaf tops it at 23.6 cubic feet, but the Kona's footprint is almost a foot shorter than the Nissan's. Visually, the Kona Electric is distinguished from its petrol-powered sibling by a grille-less face, replaced by an LCD readout grid pattern with the charging port neatly hidden beneath a panel on the left side. A new light bar spans the prow, connecting the upper driving lights in a digital wave pattern repeated in the lower front, side and rear skirts. It's meant to evoke the pathways in a circuit board, according to senior chief designer Chris Chapman. Inside, more differences serve to remind you that you're sitting not just at the helm of a crossover, but a shuttle to the future. An array of PRND buttons and an electronic parking brake await your instructions. Neither seemed necessary nor an improvement over the Kona classic's tried-and-true gear selector and handbrake, but there they were. The e-e-brake perhaps does permit the double-decker center console, though, the lower level meant for gadget recharging, whether via USB or Qi wireless.
