Adding a natural gas fuel system increases manufacturing costs by approximately how much?

Answer: C — $20,000

The choice stating that adding a natural gas fuel system increases manufacturing costs by approximately $20,000 is grounded in industry standards and practices. This figure reflects the additional expenses associated with designing and integrating the natural gas system into a vehicle. These costs encompass several factors, such as the materials needed for the fuel storage tank, piping, fuel injectors, and the overall alteration to the engine to accommodate natural gas. Moreover, manufacturing facilities may encounter increased labor costs due to the need for specialized skills and technologies required for installation and safety compliance. In addition, the investment in necessary testing and certification processes to ensure that the vehicle meets regulatory standards adds to the overall cost. Thus, the figure of $20,000 aligns with the typical financial implications seen in the trucking industry when transitioning to a natural gas fuel system.
