Hi Robert,
I’ve been thinking about buying a new 2018 Nissan LEAF. But I’m having a hard time wrapping my head around all the terminology related to electric vehicles. Could you explain what MPGe is and how it’s measured?
Thanks,
Tony

Hi, Tony!
Don’t feel bad! The rise in popularity of cars like the 2018 Nissan LEAF has brought a lot of new measurements and concepts. MPGe stands for “miles per gallon (gasoline) equivalent†and it's how we compare the efficiency of internal combustion engined automobiles against electric vehicles.
The Environmental Protection Agency (EPA) has rated one gallon of gasoline as containing 115,000 BTUs of energy. This equates to 33.7 kilowatt-hours (kWh), which is what the battery packs in electric vehicles are measured in. Since we know how the values relate, we can accurately judge how efficient they are comparatively.
The 2018 Nissan Versa, for example, returns 31.05 mpg. So, for every 31.05 miles you travel, you’ll have used one gallon of gas.
The 2018 Nissan LEAF, alternatively, gets 112 MPGe. So after you’ve traveled 112 miles, you’ll have used 33.7 kWh of energy.
Thanks for the question, Tony! Why not call into Kirkland Nissan, Washington and see if an electric car is for you?
