Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.

Did the Chevy Corvette Z06 break 7 minutes at the Ring? Not likely

"Just because it's on the internet doesn't make it true." That's rule number one, two and arguably, three, of surfing the world wide web. In today's example of this rule, we have the following. The website HorsepowerKings is claiming that a 2015 Chevrolet Corvette Z06, with the eight-speed automatic and Z07 package, managed to lap the Nurburgring Nordschleife in under seven minutes. To put that in perspective, that super-quick time would put the 650-horsepower, $97,000 (the price of a 2LZ with the Z07/8AT combo) Z06 a mere two seconds slower around the world's most challenging race track than the $929,000, 887-horsepower Porsche 918 Spyder Weissach. It's about eight seconds quicker than Nissan's own test of the GT-R Nismo Track Pack and 13 seconds faster than a Dodge Viper ACR. Unfortunately, Chevy says there isn't anything to it. We reached out to the Bowtie's Monte Doran, who confirmed that HK's claims are "not accurate." "Any one – a manufacturer, a journalist, a guy standing on the fence of the Ring – can claim a lap time. As such, we think the in-car video is essential to proving a time is real and credible, and Chevrolet will not release a lap until we have a video to substantiate the claim," Doran told Autoblog. "Chevrolet accumulated nearly 1,000 miles of testing on the Nurburgring with the Z06. During that time, we only had two opportunities to run a lap on video – and both were rained out. If we get a lap on video, we will post an official time." Doran finished by referencing the "only official lap time" for the Z06 – a 2:41 around the Virginia International Raceway. Frankly, we aren't terribly surprised by Chevy's position. One would imagine if the Z06 were matching million-dollar hypercars around the 'Ring, the company would literally be screaming about it from Renaissance Center's rooftop. As this is quite the opposite of that, though, we're betting that the real Z06 lap time - while still likely very, very fast – won't be quite quick enough to frighten the brightest and best of today's hypercars.

Why the Corvette is Chevrolet's billion-dollar baby

Edmunds has worked up a piece that tries to figure out just how much the global Chevrolet Corvette economy is worth, a spitballed guesstimate putting the number at more than $2.5 billion with the proviso that the number is probably low. It starts by taking Corvette's new car sales of 14,132 units last year, which would equate to $714,725,900 (including destination) assuming ever car sold was a base coupe with no options. In the final tally, a little extra padding gets that number up to $750,000,000.
But that's not all. Consider this: Many of the almost 1.4 million Corvettes produced over the model's history are still on the road. There are new parts being produced and aftermarket companies like Mid-America Motorworks deaing business, that single Illinois company doing more than $40 million a year in sales. There are the Corvette events large and small, restorers who do nothing but Corvettes, salvage yards that deal only in used Corvette parts and the Corvette magazines where owners find all this stuff.
And then there are the Corvette-themed tchotchkes, every single one of which provides a tiny contribution to the huge licensing royalties that General Motors collects every year. The article admits there's no way to come to an accurate number, but it just goes to show how valuable one specific model can be to a company.
