Ashphalt 8: Nitrous and Electric Cars

Just an idea, how can nitrous work in an electric car?

AFAIK, nitrous works by releasing extra oxygen in an internal combustion engine leading to better fuel ignition and therefore a faster operation.

But, an electric motor works by moving electricity through a coil in order to generate a magnetic field which leads to the shaft rotating and therefore moving the car, no oxygen is involved in the process.

So, why does nitrous work in the electric cars in Asphalt 8?!
