Price tags have just been placed on General Motor’s bi-fuel options for its GMC Sierra HD and Chevrolet Silverado 2500 HD models, and the added mileage is going to cost big bucks up front.
The bi-fuel option allows the vehicle to switch between CNG (compressed natural gas) and petrol fuels, and to acquire the capability buyers will have to drop $11,000. The upgrade adds a Type 3 tank in the bed that gets you a 650-mile range on any heavy-duty truck variant.
GM justifies the cost of the bi-fuel option saying that it serves as protection against gasoline prices that are unstable at best, and that in the end, owners can potentially keep $5,000 to $10,000 dollars that would have otherwise been spent on fuel over a three year period.
Although it has the potential to save a lot of money on fuel, not only is CNG not very widely available in the U.S., taking that kind of time to see a payoff on an investment in something that constantly depreciates in value doesn’t entirely add up.
