What are the primary considerations for CNG vehicle design?

The primary considerations for CNG vehicle design center around structural integrity because vehicles using compressed natural gas (CNG) operate under specific pressures that demand robust construction. The gas is stored in high-pressure tanks, which require suitable materials and designs to withstand significant forces. This includes ensuring that the tanks can endure impacts, temperature variations, and potential leaks without compromising safety.

While other factors such as tank color, interior upholstery, and driver comfort are important for aesthetic and usability purposes, they do not directly influence the vehicle's ability to safely contain and use CNG. Structural integrity is essential for preventing failures that could lead to dangerous situations, making it the most critical factor in CNG vehicle design. Maintaining robust structural integrity not only ensures safety but also affects the overall performance and reliability of the vehicle in CNG applications.
