I just saw a video about an electric car which has an ECO mode.
In ECO mode the car has less power.
So let's say in normal mode the car has 100 kW and in ECO mode 60 kW.
But why should the range of the car be greater if it has less power?
Because as far as I know to reach a speed of v it takes this energy:
[tex] E=m v^2/2 [/tex]
As you can see the acceleration or power is not part of the equation.
It should not matter if you reach the speed with the power of 100kW or 60kW.
So why is the power reduced in ECO mode?
