Practical range considerations
How fuel tank size translates to driving range
Driving range depends on fuel economy, driving style, and terrain. With a typical combined fuel economy in the high teens to low twenties miles per gallon for these engines, the 20.5-gallon tank would provide several hundred miles of range under normal driving conditions. The actual range will vary by trim, maintenance, and driving habits.
