Recently our spies caught a lightly disguised 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 received these pictures of a completely uncamouflaged 2011 GMC Sierra 3500 dually
The new Sierra 3500 HD 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, generating at least 700 lb-ft of torque. Although GM hasn’t released exact power figures, they have confirmed that it will top the 365 hp and 660 lb-ft. of torque from the 2010 model. GM says the new Duramax also reduces emissions by a substantial 63 percent, and also features B20 diesel capability. The new 6.6-liter will however require the addition of diesel exhaust injection refills every 5,000 miles.
An enhanced Allison 1000 six-speed automatic transmission will also be part of the new package. It will come with tap up/tap down driver shift control and an elevated idle mode to speed the warm-up process. GM says that the transmission helps 6.6-liter 3500 HD models accelerate to 60 mph in less than 9 seconds, a 0.3 second improvement over the outgoing model.
What else might GM have up it sleeve? We hear from our sources that GM is working on a large displacement (approximately seven liters) direct-injection gas engine that would produce gobs of power but with a much lower price tag than the Duramax diesel. The new DI gas engine could arrive by 2013.
GM took the wraps off of the Chevy Silverado HD trucks at the recent Chicago Auto Show, but we are still waiting for the Sierra to be follow suit.

when my old man was switching from a Silverado to EXT for a company vehicle, there was a week delay and he drove a lifted 2500 crew cab with long bed for that time.
i took it down to a double drive-thru Tim Hortons (where all the ricers sit showing off there zing-zing v-tec’s, faux carbon fiber and flickering underglow), parked it right in the middle of their little d-bag gaggle-****, took up 1.5 spaces wide and 2 long.
i got out and had about 16 kids looking at me like i had just not knowingly parked on top of an Si. went in got the coffees, came back out, as i was walking towards the truck i confirmed that hadn’t parked over top anyone’s ‘whip’.
i had left it idling with my buddy and his girlfriend inside. when i got back in it, they said after i had walked passed them all i got some weird hand gestures that were described as helen keller throwing a **** fit. when i pulled out and was driving away i saw in the mirror that i was being flipped off, i backed up and again sat in the middle of their gathering in park reving it and people inside the building actually came out to see if one of the Saki-bombs was capable of the noise… 3 wanna be Xzibits got all high and mighty and hopped in their cars and actually tried to get there coffee cans to drown out the V8, i had my window down and was laughing my ass off and drove away.
point of this story, there isnt really one, just that large ****-off trucks are in fact large and you should **** off

aggie531, that’s just an example of GM’s competition squirming. Funny to watch the panic ooze from them

Andy – you should have parked on one of the cars in the Timmies parking lot. Nothing says performance sound like an import that sounds like weed whacker. I would take a set of magnaflow mufflers on a LS1 Silverado any day over a coffee can on import. The low key growl is much better high impact buzzing.
