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.

Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

First 2015 Chevy Corvette Z06s en route to owners [w/video]

Pretty much right on schedule, Chevrolet has begun shipping the very first customer examples of its 650-horsepower, supercharged Corvette Z06. In fact, according to General Motors, the earliest Z06s could be in customer hands by the end of this week. "It has been an incredible opportunity to work on Chevy's most capable model," said Jeff Lamarche, manager of Chevy's Bowling Green Assembly plant. "It truly is an amazing car, and we're thrilled to get them into the hands of our eager customers." Prices for the Z06 start at $78,995 for the hardtop model, while the first-ever Z06 Convertible kicks off at $83,995. Take a look below for the official press release from Chevrolet, and while you're down there, we've slipped in a new video of Corvette Racing's Tommy Milner taking a hot lap of Road Atlanta in a Z06, complete with some Performance Data Recorder footage. First 2015 Corvette Z06s on Their Way to Customers Most capable model in Chevrolet's history now shipping from Bowling Green BOWLING GREEN, Ky. – Chevrolet is now shipping the all-new 2015 Corvette Z06 coupe from Bowling Green Assembly and some early customers could receive the much-anticipated supercar later this week. "It has been an incredible opportunity to work on Chevy's most capable model," said Jeff Lamarche, plant manager of General Motors' Bowling Green Assembly plant, "It truly is an amazing car, and we're thrilled to get them into the hands of our eager customers." The new Corvette Z06 offers the most choice for customers in the model's history. It is the first Z06 to offer an available eight-speed paddle-shift automatic transmission and, thanks to a stronger aluminum frame, a removable roof panel. In addition, it is the first time since 1963 that the Z06 is available as a convertible – which will arrive in early 2015. The new LT4 supercharged 6.2L V-8 engine is SAE-certified at 650 horsepower (485 kW) at 6,400 rpm and 650 lb-ft of torque (881 Nm) at 3,600 rpm – making the 2015 Corvette Z06 the most powerful production car ever from General Motors and one of the most powerful production cars available in the United States. To balance performance and efficiency, the LT4 leverages a trio of advanced technologies – direct injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing –with a new, more efficient supercharger. The LT4 helps make the Corvette Z06 the most capable car in the brand's history.
