2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

Chevy Corvette Stingray "colorizer" lets you chase the rainbow

After you've convinced your better half to let you buy a new Corvette, then comes the hard part... actually figuring out which 'Vette you want. While Chevrolet has yet to release the official configurator for the 2014 Corvette Stingray, it did give us something else to kill some time playing around with.
The C7 Corvette "colorizer" recently went online, and it lets you look at the car in all of its available colors and wheel options from four different angles so that when this car does go on sale, you know exactly which one you want. It includes the Corvette's full pallet of colors including Torch Red, Laguna Blue and the hue you see above, Velocity Yellow. Toss in the black wheels, and we're sold. If you have some time this afternoon, be sure to check it out the Corvette colorizer for yourself, and even if you don't have the time, we've put together a gallery with all of the possible color combinations.

This is your 2014 Chevrolet SS

Think you've waited long enough for this? If so, then you'll want to savor the high-res photos we've so far been given of the 2014 Chevrolet SS, the first rear-wheel-drive performance sedan from The Bowtie in 17 years.
We all know its our version of the brand new VF-model Holden Commodore, but what's under the hood that earns the appellation "performance?" A 6.2-liter LS3 V8 engine producing 415 horsepower and 415 pound-feet of torque. That's 35 hp and lb-ft less than the same engine is expected to produce in the 2014 Chevrolet Corvette. Chevrolet says the sedan will get from 0-to-60 miles per hour "in about five seconds."
Shifting comes courtesy of a six-speed automatic with paddles on the steering wheel, while stopping arrive via four-piston Brembo calipers up front, a single sliding piston in back. The forged aluminum wheels are 19-inchers all around, each set supporting right around 50 percent of the sedan's weight, and the aluminum hood and trunk are meant to keep the center of gravity low.
