here's how it goes
1. u slow down towards a traffic light junction.
2. u applied the brake and the electri motor inside the wheels turn into generators to recharge the battery.
3. u reach a halt at the traffic light.
4. after 6 seconds then the ECU think u r at a traffic light and it switched the engine off altogether.
5. when the lights went green, u step on the accelerator and car moved on using electric motors. moments late the engine take into action as u built up speed.
