Always a venue for the debut of new trucks, configurations and technologies, Chevrolet has chosen the Chicago Auto Show as the place to roll out its 2015 Silverado 2500 HD CNG work truck. That "CNG" of course stands for "Compressed Natural Gas," the second fuel, in addition to gasoline, that the Silverado is able to run on.

As reported earlier, the HD CNG truck features a bi-fuel setup for its 6.0-liter V8 engine – this "LC8" version has hardened valves and valve seats to allow it to run natural gas. The mill produces a robust 360 horsepower and 380 pound-feet of torque when burning gasoline and 301 hp and 333 lb-ft on CNG.

Of course the positive side of the CNG trade-off is lower running costs and emissions. Chevy estimates that a CNG Silverado HD could save its its owner $2,000 per year over 26,000 miles if the vehicle in question is firing on CNG 75-percent of the time. Multiply that advantage over a few trucks in a fleet, and you've really got something.

We've got live images of the new 2015 Silverado 2500 HD CNG from the Chicago show floor in our gallery above. You can also dive deeper into the specifics of the truck in the press release, below.

2015 Silverado HDs Run Cleaner, Save Money on CNG

CHICAGO – Chevrolet's expanded availability of bi-fuel versions of the new 2015 Silverado 2500HD and 3500HD trucks give customers and fleet managers more choices for cleaner-burning compressed natural gas-powered models – and savings at the pump.

With CNG currently priced about 62 percent less per gallon than gasoline, a work truck driven 26,000 miles a year can save more than $2,000 annually based on 75-percent CNG usage and comparable efficiency to gasoline.

"With CNG capability to be offered on all Silverado HD cab configurations, customers have a wider range of choices when it comes to selecting the alternatively fueled truck that matches their needs," said Ed Peper, U.S. vice president, General Motors Fleet and Commercial. "And for companies and municipalities that maintain multiple trucks in their fleet, the fuel cost savings of CNG can really add up in a year."

The CNG option is available on all Silverado 2500HD configurations and Silverado 3500HD models with single rear wheels. The 2500HD double cab and crew cab models are on sale now, with 2500HD regular cab and all 3500HD models going on sale in July.

With the additional driving range enabled by a separate CNG tank, Silverado HD bi-fuel models have a total range of up to 650 miles, meaning less time needed for fill-ups. When equipped with a 4.10 axle ratio, the maximum conventional trailering rating is 13,000 pounds on gas or CNG.

GM warrants and validates the fuel systems of the 2015 Silverado HD bi-fuel trucks. GM's five-year/100,000-mile powertrain limited warranty covers CNG fuel systems. All major components associated with the CNG system also carry GM service part numbers, for availability throughout the largest dealer network in the United States. That's not the case with some other manufacturers' available bi-fuel trucks.

"Silverado bi-fuel pickups are available through any of Chevrolet's more than 3,000 dealerships across America just like any other model," said Peper. "It's one of the industry's most seamless integration of OEM-delivered CNG vehicles."

The unique version of the 6.0L engine – identified by an LC8 engine code – features special hardened valves and valve seats that enable it to run on CNG or gasoline. It is rated at 360 horsepower (268 kW) and 380 lb-ft of torque (515 Nm) on gas, and 301 horsepower (225 kW) and 333 lb-ft of torque (452 Nm) on CNG.

A separate CNG fuel tank enables the driver to switch between fuels at the flip of a switch. When the CNG tank is depleted, the system automatically switches to gasoline. GM's tier-one supplier installs the CNG fuel tank and complementing fuel system upgrades at a secondary location. Chevrolet dealers deliver the trucks as they would with any optional content.

CNG is cleaner burning than conventional gasoline or diesel. Today, most of the natural gas used in the U.S. comes from domestic or other North American sources. Depending on their usage habits, many customers can recoup the incremental investment in CNG vehicles within a few years, and the lower fuel cost enables a significant reduction in daily operating costs.

New Silverado HDs

The new 2015 Chevrolet Silverado 2500HD and 3500HD are engineered to be stronger and smarter than before, delivering the capability heavy-duty truck customers demand, with greater refinement for more comfort and confidence on the job and on the road.

Silverado 2500HD and 3500HD models come in Work Truck (WT), LT and LTZ trims, and are offered in regular cab, double cab and crew cab configurations. The regular cab comes only in WT and LT trims. The new double cab model replaces the previous extended cab and features forward-hinged rear doors, which allow easier access to the back seat, especially in tight parking spaces.

The trucks are available with all-new, stronger 6'6"and 8' cargo boxes with standard CornerStep bumpers, EZ Lift-and-Lower tailgates, and other features to ease cargo handling. Available updates for 2015 include:

All new cabs and interiors with increased comfort and extensive storage space tailored to the way customers use full-size trucks.

- Chevrolet MyLink, which provides powerful connectivity for work or family with simple, intuitive controls
- Integrated cruise control and Auto Grade Braking to help make trailering easier
- Standard StabiliTrak with Trailer Sway Control on all models, including 3500HD duallys.
- Models equipped with CNG system add cargo tie-downs on the tank cover and a single fuel gauge that displays fuel levels for gasoline and CNG.
- Safety features such as Forward Collision Alert, Lane Departure Warning with an Active Safety Seat, and Front and Rear Park Assist are available on the 2015 Silverado HD. Head-curtain and seat-mounted side airbags are standard on 2500 models and available on 3500 models.

Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4.9 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, and high quality.

      Damn, if I had one of these, I could run a hose from the driver's seat straight to the CNG tank and really save money.

      Save money? on Fracking Cancer Treatments? By poisoning his water? And giving his children Birth Defects? By Destroying the Working Man's HUNTING GROUNDS? The Perfect Example of Capitalism having NO Good Judgement on the Best Technology for Society.

        Idiot, why do you capitalize random words? Seriously? I get you have no clue what capitalism really is, but do you not have a clue about the english language either? You show why there should be IQ tests to vote.

          @Technoir You mean the towns where you've been able to do this long before fracking? Let me guess, you've watched Gasland and consider yourself 'informed." There's a reason, in Pennsylvania for example, that if you go back to various code books from the 40's there are sections on how to mitigate methane in well water. The ability to light the water on fire isn't from any chemicals used in fracking, it's from methane, you know the naturally occurring gas in the ground. It doesn't help that lots of areas don't have the strictest regulations on water well drilling, either. So you have plenty of shoddy wells out there. There's a reason when you see all these videos setting their water on fire it's usually younger people who haven't lived there nearly as long. If they put senior citizens on they would be able to tell you they have been able to do that for years. It's certainly a way to sensationalize the issue and misinform the masses.

          Enzo Pomares Why don't you go to a town where fracking takes place and tell people that they should be happy about burning tap water and spiking cancer rates? F U

        So you'd prefer gasoline emissions? Perhaps coal emissions? Or maybe you'd like the smog filled skyline of Milan with all that diesel burning? Or perhaps we should fill land fills with lithium ion and ncmd batteries? I'm sorry what's your point? No power source is perfect. Get over it.

      What a hideous, old truck. GM's Silverado used to be an awesome looking rig, but this looks like a flashback from the 90s, especially compared to the new Ford and Ram.

      It\'s important to accelerate slowly and drive just below the posted speed limit to save a maximum on fuel cost and help pollution even if you have this truck. Please use this truck only to carry heavy load and don\'t buy it if a small chevrolet spark or a toyota yaris can be use instead. Don\'t buy new vehicle and only buy used cars or trucks as it help pollution too. Try to read fast and write fast in blogs to save electricity that pollute also and don\'t write unnessary comments as it use electricity for yourself and the ones that read it. Plan your errant long time in advance and try to limit them to a maximum, no more going somewhere alone in a car, bring friends or neibor with you for shopping once every month. Try to make friends with cars and think about selling your car, a small moped or bycycle can possibly replace your car or truck.

          People like you are the cause of the problems we are having. Money worth less, fewer jobs...we are wasting and exporting lots of money for oil, with no money in the local economy to circulate and hire people. Air pollution... exhaust from trucks, refineries, and power plants to generate the power to refine oil. Water pollution...oil spills, chemical spills, pipeline spills...

      now before anyone gets carried away...google BAC and find out how much the conversion costs, because much like Fords CNG offerings it is but a PREP package sans tanks and fuel delivery systems, and they are upwards of $10000 for the upfit ( last i checked they were $14000 on several vehicle, but Im guessing prices may have come down )

      good engineering....perhaps the ugliest pickup ever built. Chrome is HORRIBLE GM! Cant u ever catch on???? And completely square wheel openings???????? I could easily design a better looking truck. No wonder youre trucks dont sell on par with others. Even Ram has passed u up in looks. Get your act together. I own a GMC truck too. I'm not a GM hater, because I know they are good trucks, albeit with terrible bodies.

      A lot of CNG options being shown. I wonder why? Do they get partial credit for a EV? My guess is that they are trying to to get drivers ready for hydrogen. If CNG can not catch on fast then hydrogen won't. So far CNG has done horrible and fueling up has so many problems that people looking for a alternative will go EV or PHEV. Fast CNG stations can leave you with less than 100 miles range and they are nowhere to be found. Home fill stations take all night to compress from 3psi to 35000 psi and burn a lot of electricity in the process.

      What is the CNG only range? I realize the CNG tank is 17 Gallons.
