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.

Next Corvette ZR1 to get 700 horsepower?

Word has it General Motors may offer as much as 700 horsepower in the C7 Corvette ZR1. Motor Trend reports the next Corvette Z06 will continue to rely on its naturally aspirated 7.0-liter V8 engine for thrust, but the lump will deliver substantially more power. How much more? MT says the engine could deliver up to 600 ponies. That's a jump of 95 horsepower over the current Z06, though no figures have been finalized as of yet. Right now, GM is reportedly waiting to see what sort of grunt it can glean from the next ZR1.
The automaker has already made it clear it will resurrect the LT5 name for the new supercharged V8, and if GM is already pulling 600 from the Z06, the big dog ZR1 would theoretically offer 700 horsepower. Either way, the range-topping Corvette will be suitably insulated from its less potent siblings. Stay tuned. We aren't likely to see the Z06 for at least a year, with the ZR1 trailing along at some point there after.

Personal testimonies show real-world effect of plugging in with Chevy Volt

At this point, there are tens of thousands of individual stories about what it's like to live with a Chevrolet Volt. But it also remains informative to take a look at one of these in depth. For example, one Atlanta-area Volt owner says he's cut his cents-per-mile ownership costs by almost 40 percent compared to his previous car primarily because of his ability to drive almost all the time on electric power. Jeffrey Cohen told Clean Technica that he put about 14,000 miles on his Volt extended-range plug-in hybrid for the year that ended October 2013, and that more than 92 percent of those were on electrons. He estimates his "lifetime" miles per gallon rating at a whopping 384 mpg, a figure pushed upward by the fact that he installed a Level 2 charger at home while his employer added an external 110-volt charger at work. Cohen is spending 45 cents a mile for his car, compared to 73 cents in his Infiniti M35. As a result, he's spending 45 cents a mile for his car, compared to 73 cents a mile with his prior vehicle, an Infiniti M35. About two-thirds of those Volt costs are for the $349-a-month lease payments, while 15 percent is insurance, 11 percent is for the charger and seven percent for the gas and electricity that actually powers the car. Helping lower that last figure is an overnight electricity rate that's about 10 percent of Cohen's daytime rate. Chevy parent General Motors hopes such testimonies will re-trigger sales for the Volt in 2014. Last year, GM sold 23,094 Volts, down 1.6 percent from 2012.
