2015 Chevrolet Silverado & GMC Sierra 2500HD & 3500HD info

[06_GMC]

Loving the way the Sierra looks!! I will be waiting for a better gasser option down the road before I consider buying one.

I like!!! Ohhh man...I wanna test drive one

 

FWIW Duramax has always been DI...

The Chevy 2500 has the grill that the 1500 should have had.

 

Still like the Sierra better (1500 and 2500).

Hi everyone. Sorry for dropping out of this thread yesterday without notice. My flight arraignments changed rapidly yesterday afternoon and I went from having 2-hours free, down to 15-minutes to eat lunch and get on a bus to the airport unexpectedly.

 

OK, so that said.. here's a few more photos I snapped but didn't get a chance to post. Sorry if I've re-posted an image or two.

like the looks of the HD's, they look big, which is a good thing is this segment. Disappointed as are most that they powertrains didn't get any upgrades.

[c0boy]

I think they did a great job with the new HDs, but forgot about the power trains. Even as a Chevy fan, if I were in the market for a diesel HD (3500), I would go for the Ram with 850lbs and their heavy duty with their Aisian heavy duty transmission. Same warranty as Chevy/GM too. If I were in between a 1500 and HD and still buying Chevy I would opt for a 1500 with the 6.2 as long as I didn't need the payload.

Looks like they only had the 8ft bed on the 3500s on display? Trucks look nice regardless.

I like the Sierra non dually truck. Too bad the Sierra Dually has the Chevy Dually bed sides and taillamp openings - making it look like a Chevy from the rear and not matching the design of the Sierra front fenders.....surprised.

Always been a Sierra fan with the GMT900 platform...but now it´s the opposite...damn this new Silverado HD looks good

[newdude]

Good those stupid black "things" near the cowl with the engine nameplates are gone. Hood looks much cleaner.

How do you guys feel about the natty gas ability for the 6.0?
Reason I ask is that I go to school for Petroleum Engineering, and a topic that always comes up is the "chicken or the egg" with Natural Gas powered vehicles.

Considering close to me here in Laramie a GGE of Natty gas is a measly $1.50 per gallon, I would figure potentially that if we give tax breaks to service stations, it would be a heckuva deal, even if mileage suffers approx 20% with the gas.

Consider it's 100% cheaper in cost, or at least 60% in most states......I know I would be running it if I could.

Natural gas is for your furnace, propane is for your BBQ, gas is for washing your hands and diesel is for your truck.

Have the solved the 'range' between fillup issue yet for nat gas?

[Charlie5280]

The BTU's of energy from Natty gas are less then that of gasoline (octane), and diesel fuel.

That said, if it's $1.50 per gallon.....that's a helluva lot cheaper then diesel. So much less expensive, in fact, it's why UPS and other commercial entities use it instead.

The biggest issue with range is going to be tank technology......but I can see why having only 250miles vs 360 for a gasser would dissuade some people.

[barky]

Yes BTU content is lower, but Octane is MUCH higher, around 130. Many nat gas generators have 13:1 Comp ratios W/O turbos. A straight nat gas engine can be very efficient compared to gasoline engines. The problem is when you duel fuel them the nat gas side suffers big time. Ever seen a nat gas diesel cycle generator? They are super efficient.....
