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.

2014 Chevy Cruze Diesel destined for Chicago debut

It's been a little over a year and a half since General Motors first confirmed plans to offer a diesel-powered Chevrolet Cruze here in the United States, and we've now learned that the oil-burning compact will debut under the lights of the Chicago Auto Show in February. According to GM Authority, the Cruze Eco-D will be introduced as part of the entire 2014 model year Cruze range, set to go on sale in the second quarter of this year.
Earlier reports have indicated that the diesel Cruze will be able to achieve fuel economy numbers in the range of 50 miles per gallon. For comparison, the similarly sized Volkswagen Jetta TDI is rated at 30/42 mpg city/highway, but as we found out in our long-term test of the 2011 model, hitting 50 mpg was a piece of cake.
Official specifications will be released at the time of the 2014 Cruze's unveiling, though reports have stated that the sedan will be powered by a reworked version of the 2.0-liter turbo-diesel inline-four found in the Holden Cruze CDX overseas. In that application, the four-pot oil-burner produces 160 horsepower and 265 pound-feet of torque - increases of 20 hp and 29 lb-ft over the 2.0-liter engine used in VW's Jetta TDI.

PickupTrucks.com's latest test results in a familiar winner [w/video]

PickupTrucks.com has gone and thrown the latest batch of half-ton pickups into a cage match to see who would come out on top. The site put the 2014 Chevrolet Silverado 1500, GMC Sierra 1500, 2013 Ford F-150, Ram 1500, Toyota Tundra and Nissan Titan through a battery of tests. Those included 0-60 miles per hour acceleration, 60-0 mph deceleration, fuel economy, a hill climb, and payload and towing. They even threw the rigs on an autocross course to evaluate overall handling. Each truck was given points based on how it scored in each evaluation.
Who came out on top? Somewhat surprisingly, the 2013 Ford F-150 walked away with the gold, though fewer than 50 points separated first and fourth place. Head over to PickupTrucks.com to read the full evaluation and the final results. You may be shocked to see exactly where some of the segment's newest additions placed.
