E, or Efficiency, is just the amount of speed added divided by the number of ranks added.

The higher the E value is, the more efficient the upgrade is.

You can calculate the ranks added by using Multiplayer Math, which shows that the Evoque's weightings are 10/60/15/15, which means that acceleration adds one in ten ranks, top speed adds six in ten ranks, and handling and nitro each add one and a half in ten ranks.

Each upgrade also has the following weightings: Level 1 = 10%, Level 2 = 15%, Level 3 = 20%, Level 4 = 25%, and Level 5 = 30%. This is very similar to the previous concept.

The upgrades become complicated when Pro Kits are involved, as the Pro Kits blend multiple stats together. Also, upgrades become even more complicated when Tuning Kits are involved. Since only Max Upgrades affect the Tuning Kit bonus, Pro Kits can be disregarded here. Level one Max actually adds the speed value of level two, meaning that the car already starts off like this if a Tuning Kit is added; 0101 0000. Level two Max adds the speed value of level three, level three Max adds the speed value of level four, and level four Max adds the speed value of level five. However, level five Max adds the final Tuning Kit bonus, which is always smaller than the Tuning Kit bonus provided by the speed gap between Max level 4 and Max level 5. Therefore, Max level 5 decreases the Tuning Kit bonus and thus is less efficient than all of the previous upgrades. Due to the nature of how division works, Max upgrades always slightly decrease in efficiency from level one to level four, and then greatly from level four to level five.
