Most Economical / MP$

leave a comment »

The only way to comprehend transportation economics is to use a common metric. Miles per gallon is fine for comparing efficiency, but only for like vehicles.

Try comparing a MPG for gas and a MPG for diesel. There’s different costs per gallon for the two fuel types which makes true comparison limited.

Then there’s dollars for kg, for hydrogen fuel cell vehicles versus dollars per kWh for electric vehicles. This compares raw energy costs but not consumption.

A Miles per Dollar metric is needed to compare all the different engine types and fuel types. EVs are the most economical at over 18 mp$ at conservative numbers. Compared to 6 mp$ for a gasoline vehicle, EVs are over three times as economical.

Most Efficient

At 67-81% ‘tank’ to wheel efficiency, EVs are the most efficient at what they do, move you from point A to point B. Compare a gasoline vehicle to an electric vehicle in energy consumption and it’s an easy 4:1 ratio, that’s 4 times wasteful!
