I was standing at a stop sign, trying to make a right turn. Car was on 1st Gear, my legs on Brake , Clutch and Accelerator.
Suddenly, I felt like, someone hit me (a big bang) from behind and my car and my engine stopped and will not start.

I got down from the car however the car behind had a 1 meter gap and there was no dent on my rear bumper.

I tried to start after couple of minutes and the car started and I drove away from that spot. From the sound / car movement, I can not figure out, what's broken.

I need some expert advise, as to what has caused that BANG ?
