EV vs ICE efficiency math.

Another way to look at EV vs ICE efficiency using real world numbers.

2021 Mercedes S550 weighs 4750# and has 22.2 gal gasoline capacity. The 22.2 gal of gas is equivalent to 748KW in energy with an EPA range of 533 miles. That is 0.71 miles/KW.

2021 Model S LR+ weighs 4880# and has 100KW battery with an EPA range of 391 miles. That is 3.91 miles/KW

The efficiency ratio in this case of EV/ICE ~3.91/0.71 or 5.5X
