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.

Junkyard Gem: 1987 Chevrolet Turbo Sprint

Fifteen years ago, I wrote my first-ever automotive article under the name Murilee Martin, and it didn't take me long to start writing about one of my favorite automotive subjects: the junkyard. Before I'd refined my system for documenting discarded vehicles, however, I shot a lot of boneyard photos that never got used. For today's Junkyard Gem, I have four shots from early 2007 of one of the rarest turbocharged machines of the 1980s: the Chevrolet Turbo Sprint. The Chevrolet Sprint was really a rebadged Suzuki Cultus, from the pre-Geo era when General Motors sold the Isuzu Gemini as the Chevrolet Spectrum, the Daewoo LeMans as the Pontiac LeMans and the Toyota Corolla as the Chevrolet Nova (soon enough, the Spectrum became a Geo, and the Nova became the Prizm). The second-generation Cultus appeared in 1988, becoming the Geo Metro on our shores the following year. The Turbo Sprint was available for just the last two years of the Sprint's 1985-1988 American sales run, and it appears that just a couple of thousand were sold; if I'd known at the time just how rare they were, I'd have shot more photos of this one at the now-defunct Hayward Pick Your Part. The turbocharged 993cc three-cylinder produced 70 horsepower, 22 better than the naturally-aspirated version. Since the Turbo Sprint weighed just 1,620 pounds (that's about 500 pounds lighter than a barely more powerful '22 Mitsusbishi Mirage), it was plenty of fun to drive. For 1988, the regular Sprint hatchback cost $6,380 while the Turbo Sprint listed at $8,240 (that's about $15,375 and $19,855 today, respectively). Believe it or not, a Turbo Sprint actually raced in the 24 Hours of Lemons 10 years ago, though it didn't end well. This ad is for the regular Cultus, not the Cultus Turbo, but the screaming guitars sound reasonably turbocharged. For the most part, Chevy Sprint marketing was all about cheap purchase price and stingy fuel economy… at a time when gasoline prices were cratering. Related Video:

Ram 1500 bests new F-150 in MT pickup shootout

Ford's 2015 Ford F-150 is a technological tour-de-force, what with its aluminum-intensive construction and its powerful and efficient new 2.7-liter EcoBoost engine option. But now that it's hit the market, it's time to get down to brass tacks and find out how just the latest F-150 actually stands up to its rivals in the hyper-competitive fullsize segment. Motor Trend is among the first to round up the Ford (in Lariat 2.7-liter 4X4 guise here) and put it up against the Ram 1500 Outdoorsman EcoDiesel 4x4 and 5.3-liter-equipped Silverado 1500 LTZ Z71 to find out how Dearborn's new-think truck measures up. The test put the trio through over 1,000 miles of tough driving in California and Arizona in a variety of conditions from just cruising around unladen to hauling a trailer. MT found all three trucks to be competent, but the most praise got heaped on the Ram and the Ford, with the Chevrolet falling a step behind its competitors in many tests. Among the Ford's most-liked features was its 2.7-liter, twin-turbo V6 that helped make the F-150 easily the quickest of the group, with some editors saying the engine felt about the same whether driving around with cargo in the bed or not. There was some minor turbo lag during acceleration while trailering, but that issue affected the Ram, too. The Ram's powertrain was lauded, as well. The EcoDiesel was torquey around town, and the 1500's combination of an eight-speed automatic and air suspension was judged to be the best of the lot. It was the most difficult to get into the bed, though. The Ram also won the fuel economy award by netting 20-miles-per-gallon city and 28-mpg highway in the test to beat its Environmental Protection Agency ratings of 19/27. The Ford's EcoBoost managed 17/22, one mpg off each from the EPA numbers, and using a lot of throttle really depleted its efficiency. As MT notes, however, it would take time for the diesel's mileage savings to pay off at the pump for these two trucks. In the end, the Ram just barely eked out the win, with the title partially earned because of "the Ford's unknown maintenance and aluminum repair costs," according to MT.
