Fuel & MPG / Battery & Range
| Fuel type Fuel type refers to the kind of energy source used to power an engine or appliance, such as gasoline, diesel, electricity, or alternative fuels. | Regular unleaded |
| Range in miles (city/hwy) Car range refers to the distance a vehicle can travel on a full tank of fuel (or a full battery charge) and is usually measured separately for city driving—which often gives a lower range due to stop-and-go traffic—and highway driving, where steady speeds generally result in a higher range. | 0/0 mi. |
| Fuel tank capacity A car's fuel tank capacity is the maximum amount of fuel it can hold, usually measured in liters or gallons. | 36.0 gal. |
Engine
| Base engine size The car’s base engine size usually refers to its engine displacement, which is the total volume of all the cylinders (measured in liters or cubic centimeters). | 6.6 L |
| Cylinders Car cylinders are the chambers in an engine where the combustion of fuel occurs, driving pistons to create mechanical power. | V8 |
| Base engine type A car’s base engine type refers to its fundamental design—typically the configuration (like inline, V-type, or boxer) and the fuel it uses (gasoline, diesel, etc.). | Gas |
