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.

These are the 10 longest-lasting vehicles on the road today

Buying a car has started feeling pretty bad. It’s hard to find what you want, and when you do, thereÂ’s a great chance itÂ’s not selling for the price you thought it would be. The least stressful way of coping with the situation is not to buy a new car, but how can you know how long your current ride will last? A recent study from iSeeCars found that some vehicles are prone to deliver many more miles of usable driving than others. iSeeCars looked at more than 2 million cars. The mileage over which the top 1% of cars within each model obtained was calculated and used to rank models, and the study required that a vehicle be sold for at least 10 of the past 20 years to be included. Unsurprisingly, Toyota dominated the top-10 list, but most of the other models come from General Motors with one Honda thrown into the mix. Ranked by mileage, the top-ten longest-lasting vehicles include: Toyota Highlander Hybrid: 244,94 miles Toyota Avalon: 245,710 miles Honda Ridgeline: 248,669 miles Chevrolet Tahoe: 250,338 miles Toyota Prius: 250,601 miles GMC Yukon XL: 252,360 miles Toyota Tundra: 256,022 miles Chevrolet Suburban: 265,732 miles Toyota Land Cruiser: 280,236 miles Toyota Sequoia: 295,509 miles The iSeeCars study found that SUVs and trucks occupy 75 percent of the top 20 vehicles with the potential to last the longest, and Toyota alone accounts for half of the top 20. Interestingly, the Prius and Highlander Hybrid made the list, suggesting that automakers are getting better at making batteries last a long time. "What we see is a list of highly-durable vehicles, capable of more than a quarter-million miles of use if properly maintained," said iSeeCars Executive Analyst Karl Brauer. "And to be clear, this study isnÂ’t reporting the maximum lifespan of these vehicles. This is simply a measure of current odometer readings. Most of these cars are still in use and going strong." Of course, the longevity of a vehicle has a lot to do with how itÂ’s treated and maintained over its lifetime. ItÂ’s easy to find stories of people nursing Toyota Tundras and other vehicles past a million miles, and thereÂ’s a 1960s Volvo with more than 3 million miles. Some vehicle types, particularly the largest SUVs, are often used as road-trip vehicles by large families, which means they tend to rack up big mileage. In most cases, buying and owning a higher-mileage car can be a risk, so itÂ’s essential to get a pre-purchase inspection or regular maintenance if you already own one.

Chevy Spark EV will go on sale in Maryland

The single-charge range of a Chevrolet Spark electric vehicle may not blow away anyone who's used to driving on a topped off tank of gas. But a full charge will actually get a Spark EV about halfway across the state of Maryland. Which is good because that state will be the first on the East Coast to sell the battery-electric model. General Motors said this week that Chevy Spark EV sales will start in Maryland this spring, and that federal and Maryland tax credits will get the out-of-pocket price of the Spark EV below the $18,000 threshold. GM took the opportunity to tout the Spark EV's 119 miles per gallon equivalent rating and says Maryland has sufficient charging infrastructure for drivers to welcome the EV without too much trouble. Last June, Spark EV distribution was reported to be ready to extend beyond the Pacific Coast. Specifically, Ohio was thought to be next in line to get Spark electric vehicles after four state car dealerships listed the model on their websites. GM's Randy Fox, however, quashed that real quick, saying only California and Oregon had sufficient infrastructure to support the Spark EV. GM first announced the Spark EV for public (or at least American) consumption back in 2011. Last year, the General sold 1,145 Spark EVs, up 87 percent from 2013. For more on the Maryland expansion, take a look at GM's press release below. Chevrolet Spark EV Plugs into Maryland Customer demand drives addition of East Coast; features locally sourced drive unit 2015-01-22 WASHINGTON, D.C. – Chevrolet will start selling the Spark EV in Maryland this spring, expanding the pure electric mini-car's "range" to the East Coast. The Spark EV is the most efficient U.S. retail electric vehicle on the market, delivering an EPA-estimated combined city/highway 119 MPGe fuel economy equivalent and 82 miles of EPA-estimated combined city/highway range. It is priced as low as $17,845, after federal and Maryland tax credits – and it features a locally sourced electric motor and drive unit, manufactured at General Motors' Baltimore Operations facility in White Marsh, Md. "The Spark EV has been one of the most well-received electric vehicles in the industry and customer demand helped make the decision to expand its availability to Maryland," said Steve Majoros, Chevrolet director of car marketing.
