Watch this time-lapse build of the Chevy SS for NASCAR

There's only about a week left until we get our first look at the production version of the 2014 Chevrolet SS sedan, but Chevrolet NASCAR teams have been looking at the race version of the car all winter. Autoweek has posted a really neat time-lapse video showing just a portion of what it takes to build one of NASCAR's new Gen6 stock cars.
Though the video is quite brief, it does show almost the entire build process starting with just the car's nose, and it gives us a good look at how integral the template is to the final product. As a bonus, Hendrick Motorsports also provided some videos showing two of its teams performing pit stop tests over the winter. The second video shows some of the more detailed aspects of the racecar's rear end, including the stock-looking trunk cutout and a newly mandated rear bumper extension that will be used on super speedways like Daytona and Talladega.
To see what Team Chevy has been up to all off-season, check out all three videos posted after the jump.

GM profit dips on truck changeover, but beats estimates

DETROIT — General Motors on Thursday reported a higher-than-expected quarterly profit despite a drop in production of high-margin pickup trucks, as it gears up for new models that are expected to boost profits next year. Like rivals Ford and Fiat Chrysler Automobiles, GM is banking on highly-profitable Chevy Silverado and GMC Sierra pickup trucks to lift profits, as consumers shift away from traditional passenger cars in favor of these larger, more comfortable trucks, SUVs and crossovers. During the first quarter, the process of changing over to GM's new pickups resulted in a drop in production of 47,000 units. GM Chief Financial Officer Chuck Stevens said the production drop had resulted in a drop in pre-tax profit of up to $800 million. Earlier this year, GM said its 2018 profits would be flat compared with 2017, but expected its all-new pickup trucks would boost margins starting in 2019. On Thursday, GM reiterated its full-year 2018 forecast for adjusted earnings in a range from $6.30 to $6.60 per share. The automaker said capital expenditures were more than $500 million higher in the quarter because of investments its new pickup trucks and a family of low-cost vehicles under development with Chinese partner SAIC Motor Corp. On Wednesday, rival Ford said it would stop investing in most traditional passenger sedans in North America. CFO Stevens told reporters on Thursday that GM has "already indicated that we will make significantly lower investments on a go-forward basis" in sedans. 2019 GMC Sierra View 21 Photos GM benefited from a lower effective tax rate in the quarter, but adjusted pre-tax margin fell to 7.2 percent from 9.5 percent a year earlier. Stevens said the company's profit margin should hit 10 percent or higher in the second quarter and for the full year. GM said material costs were $700 million higher in the first quarter, and it expects those costs to continue rising. The automaker said it would counter those increases with cost cutting measures. "It is a more difficult environment than it was three or four months ago," Stevens said when asked about rising commodity prices from potential steel and aluminum tariffs announced by the Trump administration. "But we are confident we can continue to offset that." The company reported quarterly net income of $1.05 billion or $1.43 per share, a drop of nearly 60 percent from $2.61 billion or $1.75 per share a year earlier. Analysts had on average expected earnings per share of $1.24.

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.
