If anybody's interested, apparently the Chev/GMC websites are not current. It seems the 8.1 is indeed available on the 2012 trucks, as is an available 6-speed manual transmission:

"The 2012 GMC Sierra 2500 HD Crew Cab offers a transmission complete with a high-capacity six-speed ZF S6-650 manual is standard with Vortec 8100 or DURAMAX 6.6-liter turbo diesel engines...Both the short and long box 2012 GMC Sierra 2500 HD Crew Cabs come with a standard Vortec 6000 V8 (standard) with 300 horsepower engine.

Optional engines on both models: Vortec 8100 V8 (available) with 340 horsepower, DURAMAX™ 6600 Turbo Diesel V8 (available) with 300 horsepower engine."

( Vortec 6.0L V8, Vortec 8.1L V8, and the DURAMAX 6.6L Turbo Diesel).

This is good news. I have owned dozens of the Suburban 2500's with 8.1's and 2500HD's. They all used oil, but not too bad. The gas mileage was not that much worse than the 6.0 versions, but the power and low end torque were 100x better.....They are great engines that will last along time.

Dont expect much better out of a 6.0 new or old. My parents/I have an 09 2500Hd 6.0 and it averages 12 around town, and thats not with a heavy foot or towing.

that is good news. Boys its not about your likes and dislikes of the 8.1 It comes down to FORD and DODGE. What are they offering. How can I up the ante on that. And when the new platform comes out in 1-3 yrs gm needs all there ducks in a row.

I don't know how much I would trust that site you quoted. All of the spec's that are listed are completely incorrect. The Vortec 6.0L is 360hp and the Duramax is 397hp with a maximum towing capacity of 17,800lbs on single rear wheel models and 21,700lbs on dual rear wheel models. The Allison 1000 5-speed transmissions were in previous generations (2006 and older), since 2006 and the classic 2007 models GM has switched to the 6-speed transmission.

I have to agree and disagree with this statement. I have an '07 2500HD Silverado NBS and I can get 14-15mpg around town with a light foot, but I do have to be careful about accelerating and making sure to coast to stop lights/signs. With a little heavier foot, I can still get 13mpg. All non-towing miles too.

That's a BS website. Look at the truck in the picture, it's the old style front end, pre-2004. The HP specs they give are for the pre-07 Classic style. The new 6.0 and Duramax HP specs are much higher. If someone could actually show me a brand new 2011 or 2012 Silverado with an 8.1 engine in it I would gladly pull off the wiper blade inserts and eat them like black licorice.
