2015 Callaway Corvette Z06 gets new supercharger, adds $17K to starting price

Callaway's proud tradition of modifying Chevrolets is about to add a very significant chapter this weekend, as the company prepares to unveil a modified version of the 2015 Corvette Z06. The engine mods are simple, though we expect them to be very potent. That's because Chevy has replaced the factory supercharger with a new "GenThree" unit that's nearly a third larger than what's bolted on in Bowling Green. A new intercooler is also added, along with a new high-flow intake system. Beyond that, the changes are exclusively of the subtle cosmetic variety. There's new badging inside and out, as well as new engine covers, floormats and an underhood plaque. Naturally, there's documentation to verify the Callaway Z06's authenticity, and the comfort that comes with a three-year, 36,000-mile warranty. Callaway has priced the upgrade package at $16,995, in addition to the price of the stock Z06. While we're still waiting to hear official power figures, that seems like a reasonable asking price for what were wagering will be a major increase in power. The Callaway Z06 will debut this weekend at the National Corvette Museum's C7 Bash in Bowling Green, KY. Expect more details following the debut. Scroll down for the official press release.

Here's a sneak peek at the new package. Based on Chevrolet's track-proven Z06, Callaway engineers' no-compromise approach takes this Corvette to an astounding power level. While advertised Callaway horsepower and torque are pending final validation, the Callaway package adds Callaway's new GenThree supercharger system with 32% more displacement than the stock Z06 supercharger, improved manifold design and unique triple-element intercooling system. Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature. By exposing the supercharger's large plenum area to outside ambient airflow, the design takes advantage of the significant charge air temperature reduction provided by convective cooling. The completely redesigned intercooling system also helps maintain nearly ambient charge air temperature with exceptionally low air restriction.

Autoblog In Cuba: 1957 Chevy Bel Air Review

If you've been following the Autoblog In Cuba series, you may remember that my efforts to rent a car in the country were ultimately unsuccessful. Misinformation, bad planning, and a lack of rental car inventory conspired to disrupt my hoped-for driving adventure. I discovered in my week of exploration, however, that the terrific thing about Havana is that there's always another adventure to be found – if you're willing to look. A car I could drive myself might have been impossible to come by, but a ride to remember was not. After all, even when reviewing a new car, I've found that impressions about the car and the route can be credibly formed from the right seat. Starting from the parking lot of the grand Hotel Nacional, finding an interesting car for hire is as simple as walking up and down the block. Scads of classic American iron wait just outside the hotel gates, in a riot of colors and conditions befitting the tropical climate. Fords from the 1940s are plentiful – more sedans than coupes – and the glory days of General Motors are represented by enough Pontiacs and Cadillacs to fill a Bruce Springsteen B-sides album. But the Chevy Bel Air is the king of the road here, by some margin. View 30 Photos I settled on a burnt orange 1957 Chevy Bel Air convertible, in tourist-appropriate condition. I was looking for a hardtop at the request of my crew's audio/video needs, but settled on a burnt orange 1957 Chevy Bel Air convertible, in tourist-appropriate condition. This car might look good as a prop in the background on your vacation photos – hair blowing in the breeze with the ocean at your back, parked in front of Che's face in Revolution Square, etc. – but was far from pristine on a closer inspection. A perfect representative of the Cuban average. At least the price was right: $50 for two hours to make it 12 miles to Hemingway's house, and back. My driver was a kid named Daniel who looked to be about 20 years old. The Chevy doesn't belong to him, he co-drives it with the owner, but he was able to give me the basic mechanical rundown. The eight- or six-cylinder engine that Chevy shipped this convertible with was long gone. No surprise there, as nearly every American-made car I'd ridden in so far was powered by some belching Mercedes diesel. Despite it's clattering note, Daniel said the lump under the hood of the '57 drinks gas: a four-cylinder of Russian origins, pulled out of a GAZ Volga as best I can understand.

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.
