Several factors influence the fuel range of a car. Firstly, the vehicle's engine capacity and efficiency play a significant role. Larger engines with higher displacement tend to offer better fuel efficiency, allowing for longer distances on a full tank. Modern engines with advanced technologies, such as direct fuel injection and turbocharging, can also improve fuel economy, resulting in extended range. Additionally, the vehicle's weight and aerodynamics affect fuel consumption. Lighter cars with streamlined designs generally require less fuel to maintain speed, contributing to improved range.

Another critical aspect is the type of fuel used. Different fuels have varying energy densities, which directly impact the range. For instance, gasoline and diesel have different energy contents, and the choice of fuel can significantly affect the distance a car can travel. Modern vehicles are often designed to be flexible, accommodating various fuel types, but it's essential for drivers to be aware of their vehicle's specific requirements.

To calculate the fuel range, drivers can use a simple formula: Range = Fuel Capacity × Fuel Efficiency. Fuel capacity refers to the volume of the fuel tank, typically measured in liters. Fuel efficiency is the amount of fuel consumed per unit distance, often expressed in liters per 100 kilometers (l/100 km) or miles per gallon (mpg). By multiplying these two values, drivers can estimate the maximum distance their vehicle can cover on a full tank.

It's important to note that fuel range can vary depending on driving conditions and habits. Aggressive driving, frequent rapid acceleration, and high-speed travel can significantly reduce fuel efficiency and range.
