Blue-chippers reborn: The Vette is a big deal, but these trucks carry GM's future

摘要

THESE TRUCKS ARE WALL Street's Corvette. To investors, the Chevrolet Silverado and the GMC Sierra are General Motors' most important launches since the 2009 bankruptcy because of their sales and profit margins. And Wall Street appears Unimpressed with the vehicles' lack of breakthrough technology along the lines of Ford's EcoBoost F-150 or Ram's eight-speed automatic and rear coil springs. GM's new trucks begin production in the second quarter with gasoline direct-injection, cylinder deactivation, and variable valve timing across all three engines - 4.3-liter V-6 and 5.3- and 6.2-liter small-block V-8s. At launch, a six-speed automatic will be the only transmission. GM previewed the trucks before the January Detroit show without horsepower, torque, fuel efficiency, or towing numbers, although GM says they will be best-in-class on all accounts.
