2013 Bi-Fuel CNG Silverado/Sierra 2500HD Extended Cab

When it comes to managing budgets and keeping an eye on the environment, business owners and fleet managers alike face many challenges.
That’s where GM’s 2013 Bi-Fuel Silverado/Sierra comes in. It’s designed to help businesses reduce their fuel costs and environmental impact.

ENGINEERED BY GM
· The Bi-Fuel Silverado/Sierra HD Extended Cab uses
a proven, 6.0L Vortec V8 engine with factory-installed
hardened intake and exhaust valves and valve seats.
Unlike aftermarket solutions, the engine and all CNG
fuel system components are engineered to meet GM’s
rigorous standards for reliability, dependability and
safety. GM’s validation tests include: full barrier testing
(6 separate tests), 10 year corrosion, mud trough, water
fording, hot weather evaluation (including trailering),
cold weather chamber testing, altitude testing and fuel
gauge accuracy, among others
· The system automatically and seamlessly switches
from CNG to gasoline when the CNG tank has been
depleted. It also provides the flexibility to manually
switch between the two fuels at any time
· The 17 Gas Gallon Equivalent CNG tank and 36-gallon
gasoline tank provide a combined range of more than
650 miles1
· The CNG fuel tank is mounted in the truck box, just
behind the cab, and is bolted to the truck’s frame.
A Type 3 CNG tank is used to minimize payload
reduction and maximize usable box space. It is
protected by a durable, aluminum diamond-plate
cover, with easy access to the CNG filler receptacle
· The CNG bi-fuel option is available for long or standard
box models, in both 2WD and 4WD, and all trim levels
BACKED BY GM
· The Bi-Fuel CNG Silverado/Sierra HD has a
comprehensive 5-Year/100,000-Mile Powertrain
Limited Warranty 2 and a 3-Year/36,000-Mile
Bumper-to-Bumper Limited Warranty2
· The CNG fuel system, unlike aftermarket solutions,
is backed by GM’s Limited Warranty and is
serviceable by Chevrolet and GMC dealers, the
largest dealer network in the U.S.
· All CNG fuel system parts have GM service part
numbers for dependable availability, providing you
with the peace of mind that parts are available to
keep your vehicles on the road.
· Bi-Fuel Silverado/Sierra HD has available factory

Lol made ya put up a post? I get 10% royalties now.
If every one thinks about it it makes perfect sense in our area.
NG is $1 a gallon vs close to $4. I drive 30k miles a yr so im going to save approximately $6k a yr in fuel costs.
Also, there is a tax break on it which Dave is looking into. I would think it would be 3-5k. If you keep the truck 4 yrs theres no reason you cant save 20k+ in fuel + whatever the tax breaks are. Yes it cost 10k more. (Prob 8 after gm discount) but you’re still coming out way ahead and the resale is way higher too. Look on ebay.

damn, that’s pretty cool…is the MPG on the CNG any different than on gasoline?

4

We need more CNG vehicles.

5

We (the USA) is so far behind when it comes to turbo deisels and cng vehicles. But the big money in oil/gas that runs this country dont wanna have their pockets getting thinner.

6

As someone that heats his house with NG I have really mixed feelings about NG powered vehicles. I like that they help reduce our dependence on foreign oil but worry that any large scale switch to CNG vehicles will end up really costing us to heat our homes as demand for NG increases.

7

Can you fill this yourself at your house? I’d totally do this if I had to pay for fuel.

8

I have experience with CNG vehicles, they are GREAT. 150k on a Dodge Ram, no carbon build up compared to the same year Ram with less miles on it. CNG burns 60% cleaner than gasoline or diesel, is approximately 90% efficient as a transportation fuel, and would cost less than $2.00 a gallon in NY. MPGs are slightly less maybe by 1 to 3 MPG.

9

Certainly would turn the “heat up” on the Fracking debate, thats for sure…

Whats this mean?

10

You also make less power on CNG as well.

Honda also sells a civic GX that runs on CNG, they seems like good cars.

11

You could if you put in a 3000psi or 3600psi filling station.

12

Thay make them right in East Aurora, I am sure you could pick one up for about a hundred thousand. lol
There may be some permits involved as well. :wink:

There are stations all over though.

14

http://www.brcfuelmaker.it/eng/casa/phill.asp?click=no

This is a home CNG fill station… I’m sure there are more.

15

90% efficient as a transportation fuel means that 90% of the fuels energy is used to power the vehicle. 10% of the energy is lost during combustion. HP does drop slightly but it isn’t that noticeable.

16

Ahhhh ok im an idiot, I know what efficiency means, I just lost you on the transportation part but clearly you meant as being used to move a vehicle rather than say heat a home lol.

17

I think Phill just recently became available again in the U.S. They were not being produced for a while. It was around $5K if I remember correctly. Honda used to make one but bailed on it. There’s supposed to be another company coming out with one soon, but there’s not much available in the U.S. right now. The DOE is funding some research for a company to make one for a (unrealistically?) low price.

Do you guys have many filling stations available in NY? There are a good number around, but most aren’t available to the public around here.

All things equal (compression, timing, etc.), there’s about a 20% drop in power between gasoline and CNG. Bi- or dual-fuel (like TORQDSS showed) seems more reasonable if you need to make a long trip since the infrastructure just isn’t there to support this yet. And there’s the space factor for the CNG tank.

I’ve driven the CNG Civic. We had one for a few days at work. The company I work for has done feasibility studies for local municipalities about converting vehicles, and you really need vehicles that are used a lot (like garbage trucks) to justify the conversion cost.

When i was down in Mexico ALL the trucks ran on CNG. when i had my car towed the tow truck driver looked at me funny when i told him CNG isnt very common here. he told me he hadnt used his gas tank in 5 years didnt even know if it still worked.

19

Even in Cali all the public service vehicles and taxis use CNG

20

Dedicated CNG > dual fuel.

Tanks are typically 3600 psi, 8gge (gasoline gallon equivalent). Burns 1/5 the emissions of same size gasoline engine. Higher ignition point and dissipates much quicker into the atmosphere as well.

CNG is ~$1.30/gal last I checked

I do not believe the Phil stations are currently being sold.

There are two stations around here now that the one in Tonawanda got shut down. Mineral Springs/Ogden, and Niagara Falls

sucks the whole extraction method thing right now though, people are not a fan of natural gas because of hydraulic fracturing
