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.

It won't be long now before Nissan Leaf finally overtakes Chevy Volt

The two best-selling plug-in vehicles ever are the Chevy Volt and the Nissan Leaf. When the two vehicles launched in late 2010, the plug-in hybrid Volt quickly outpaced the all-electric Leaf and, despite lots of ups and downs since then, continues to hold on to a cumulative sales lead. This will change in 2015. Cumulatively, from November 2010 through November 2014, the Volt sold 71,867 units while the Leaf trails with 69,220. That's a difference of just 2,647. Based on current trends (with the Leaf selling around 2,500-2,700 a month and the Volt at 1,500-1,700) we expect the Leaf to take over either in January or, more likely, February when the Leaf takes over as the most popular plug-in car in America. Perhaps even March, depending on how low the numbers are for January and February, which are always slow sales months in the US. Of course, once it takes the crown, the Leaf can't expect to easily hold on for long. A new Volt is coming in the second half of 2015, likely beating a new Leaf to market. The question is, then, how well the Chevy sells with all of its new bells and whistles. Do you think the Volt will be the comeback kid once the 2016 model becomes available?

2014 Chevy Corvette Stingray order guide hits the web

The official debut of the 2014 Chevrolet Corvette Stingray is only part of the excitement for fans of Chevy's virtuoso sportscar. Although we got to see the car and some of its preliminary specs in Detroit and Geneva, there is still no word on pricing and some of the juicier data points we've been waiting for - such as confirmed power output, EPA estimated mileage figures and performance numbers. Until then, CorvetteBlogger has gotten its hands on the order guide for the coupe version of the car - in both base and Z51 iterations - revealing tidbits like standard and optional features and available color combinations.
Some other new details made it onto the order guide, such as our first interior specs for the coupe including slightly less hip room and headroom, more shoulder room and the same amount of legroom. To see the full order guide, head on over to CorvetteBlogger. From what we can gather, it sounds like more information will be revealed on April 25 during a party at the Corvette Museum, and for those sun worshipers patiently waiting for a convertible, it would appear you've got another model year to wait through.
