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.

Why the Corvette is Chevrolet's billion-dollar baby

Edmunds has worked up a piece that tries to figure out just how much the global Chevrolet Corvette economy is worth, a spitballed guesstimate putting the number at more than $2.5 billion with the proviso that the number is probably low. It starts by taking Corvette's new car sales of 14,132 units last year, which would equate to $714,725,900 (including destination) assuming ever car sold was a base coupe with no options. In the final tally, a little extra padding gets that number up to $750,000,000.
But that's not all. Consider this: Many of the almost 1.4 million Corvettes produced over the model's history are still on the road. There are new parts being produced and aftermarket companies like Mid-America Motorworks deaing business, that single Illinois company doing more than $40 million a year in sales. There are the Corvette events large and small, restorers who do nothing but Corvettes, salvage yards that deal only in used Corvette parts and the Corvette magazines where owners find all this stuff.
And then there are the Corvette-themed tchotchkes, every single one of which provides a tiny contribution to the huge licensing royalties that General Motors collects every year. The article admits there's no way to come to an accurate number, but it just goes to show how valuable one specific model can be to a company.

GM's Oshawa plant may close after Camaro production moves

Most of the time, when vehicle production is moved from one assembly plant to another, it spells bad news for the former. While General Motors won't go so far as to say its Oshawa, Ontario factory, which is losing the Chevrolet Camaro to the Lansing Grand River plant, is in trouble, analysts seem to think the factory's days are numbered. Forecasts for the facility are far from positive. The loss of the Camaro this year, combined with GM's targeted shutdown of a single-shift assembly line responsible for the fleet-only Chevy Impala Limited and the Equinox crossover is a bad enough omen. But with AutoForecast Solutions CEO Joe McCabe telling The Detroit News that the plant's other two products, the Cadillac XTS and Buick Regal, aren't likely to stick around beyond 2017, things look decidedly grim at Oshawa. "There is a fairly strong chance that the plant could close," Jeff Schuster, senior VP of forecasting for LMC Automotive, told The Detroit News. That doesn't mean that Unifor, Canada's auto union, and the Canadian government are going to let the factory die without a fight. And with the latter chipping in $10 billion as part of GM's 2009 bailout, you might think it has a degree of leverage in the situation. A meeting between the government and the Detroit Three at the 2015 North American International Auto Show revealed that Oshawa is already a topic of conversation. "We made it very clear that we would like to see an indication on the future of Oshawa sooner, in particular because the timing is very challenging for our supply chain to be able to adjust to potentially future orders or changes, but also to know that there are going to be future opportunities at Oshawa," Ontario's Minister of Economic, Development, Employment and Infrastructure Brad Duguid told The Detroit News. "Bottom line: It's time they made a longer-term commitment here," Unifor President Jerry Dias said, echoing Duguid's statements. It's unclear if this sort of strong talk will be enough to save 3,300-plus employees, although based on the analysts' forecasts, we doubt it.
