Last month, our spies caught a 2011 GMC Sierra 2500 Heavy Duty pickup out and about, showing off its new three-bar perforated grille that shares styling with the 2010 GMC Terrain midsize crossover.
Now, we’ve just received this picture of a completely uncamouflaged 2011 GMC Sierra 3500 dually, which sports a brand new hood that features reverse-power-dome styling with prominent center mounted louvers. It says “Duramax 6.6-liter” on the louver sides, along with the logo for the Duramax’s six-speed Allison transmission.
The Sierra HD, along with its GM corporate twin, the Chevrolet Silverado Heavy Duty, will also feature an all-new chassis and a next-generation 6.6-liter “LML” Duramax V-8 clean diesel engine.
What else might GM have up its sleeve? We hear from our sources that GM is working on a large displacement (approximately seven liters) direct-injection gas engine that would produce lots of power but with a much lower price tag than the Duramax diesel. The new DI gas engine could arrive by 2013.
