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 Colorado Z71 Trail Boss 3.0 concept heads to SEMA

Chevrolet is presenting a new take on the Colorado pickup at the SEMA show this year. The show truck picks up where the Colorado Z71 Trail Boss Edition leaves off, with numerous accessories from the parts catalog as well as several custom additions. The SEMA truck is based on a Crew Cab model with four-wheel drive, painted red with rally stripes. Among the features added from the catalog are a sport bar with LED auxiliary lighting, mounted to the cargo bed. It's also stylistically augmented with fender blares, Bowtie emblems, and rocker steps all done up in black to match the 17-inch alloys shod with Goodyear DuraTrac all-terrain tires. Chevy has also equipped this truck with an automatic locking rear diff, a transfer case shield, recovery hooks at the front, a spray-in bedliner, projector-beam headlamps, fog lamps, and all-weather floor mats. Chevy has also fitted this pickup with color-keyed door handles and mirror caps, upgraded exhaust and air intake, rubber floor liners, brushed metal interior trim, and an illuminated grille badge. Public reception will determine how many of these and other additional features will be considered for production. Colorado Z71 Trail Boss 3.0 Concept Shows Off-Road Style New styling accessories, performance parts enhance trail-ready capability LAS VEGAS – The Colorado Z71 Trail Boss Edition is designed for those who want to blaze their own trails and Chevrolet's new Z71 Trail Boss 3.0 concept vehicle enhances its off-road style with new Chevrolet accessories and performance parts. Chevrolet introduced the new concept vehicle at the SEMA Show today, where it joined concept versions of the Silverado 1500 and HD models to demonstrate the depth and breadth of the brand's three-truck lineup. "The Colorado Z71 Trail Boss Edition is made for tackling the tough terrain required to get away from it all and this concept version does it with rugged style," said Sandor Piszar, director of Chevrolet Truck Marketing. "And whether it's the Colorado, Silverado 1500 or Silverado HD, there's a Chevy truck to take you where you want to go, regardless of whether there's a road leading there." The production 2016 Colorado Z71 Trail Boss is offered in extended and crew cab configurations, with a choice of a long or short cargo bed and available 4WD – as well as the all-new 2.8L Duramax turbo-diesel, which takes the maximum trailering rating up to 7,700 pounds.

2016 Chevrolet Malibu Hybrid: 48 mpg for $28,645

With the 2016 Chevrolet Malibu Hybrid, General Motors wants to show it's as serious about mainstream hybrids as it is about mainstream midsize sedans. Keeping with the theme, Chevy announced the Malibu Hybrid will have a serious price tag of $28,645. Chevy said Thursday the 2016 Malibu Hybrid will go on sale in the spring, with that price also including an $875 destination charge. That's about $3,000 more than where the Ford Fusion Hybrid kicks off, and about $2,000 more than a Toyota Camry Hybrid LE. The big news being pushed with the Malibu Hybrid, however, is the fuel economy. GM says it's capable of 48 miles per gallon city and 45 highway, for a combined rating of 47 mpg. That's better than any other 2016 midsize hybrid sedan. Power comes from a 1.8-liter gasoline engine and an electric motor with a 1.5-kWh lithium-ion battery, producing 182 combined horsepower. That's competitive with both the Camry and Fusion. Chevy also likes to say it's roughly the same system as the one installed in the 2016 Volt – although with a smaller battery, larger gas engine, and without the plug – so the Malibu Hybrid has that halo effect going for it. With both this Malibu and 2016 Toyota Prius, there's a lot of activity around gas-electric hybrids amid lowering fuel prices and a raft of plug-ins and full-electrics. The gas-only 2016 Malibu was found to be, "at least good again," so the 2016 Malibu Hybrid should be able to attract those who want a competent midsize sedan with excellent fuel economy that awaits EPA verification. We'll go with that thought until we get to drive it.

"The Malibu leverages knowledge and technology directly from the second-generation Chevrolet Volt," said Steve Majoros, marketing director of Chevrolet Cars and Crossovers. "By leveraging technology, we are broadening our level of expertise and lessons learned to bring consumers a world-class hybrid." With an all-new, hybrid powertrain that uses a slightly modified drive unit and electric motors used in the 2016 Chevrolet Volt, the Malibu Hybrid offers a GM-estimated 48 mpg city, 45 mpg highway – and 47 mpg combined, unsurpassed in the midsize car segment. Official EPA estimates are pending.
