Frequently asked questions
Why is L/100 km different from MPG?
L/100 km measures fuel consumed over a distance, while MPG measures distance traveled per unit of fuel, so the relationship is inverse.
Is US MPG the same as UK MPG?
No. US and imperial gallons have different volumes, so their MPG figures are not directly interchangeable.
Can I compare electric cars with MPG?
Electric vehicles are commonly compared using energy-consumption measures such as kWh/100 km rather than liquid-fuel MPG.
