You must consider efficiency when setting up the car for a race

Efficiency must be considered at the design stage. It also must be considered in set up at the track.

Unless the electric race car is entered in very short races or does not have very powerful motors, it will normally be necessary to run the motors at less than peak power to complete the race with the energy stored in the batteries.

The more efficient the set up, the higher the power allowed from the motors.

Let's say adding more down force works for qualifying, allowing a faster lap time.
The extra drag will require more energy.
To complete the race with the extra wing will require running a lower power setting on the motors.

It is necessary to consider which will be faster for the race distance;
the more down force, less power or less down force, more power.
