well guyz after seeing all those questions you asked above...the engine of the car has gone and its none of my mistake as i am running it since six years in the speed between 120 to 150 and from mechanical point of view its normal for this car.Now where is the consumer protection court,my concern is not about engine or speed,my concern is about the safety.There are cars who run @300km/hr if they malfunction @200km per hour you will see first why it happened a car running with out gas being pressed...its not only amazing but a question mark on the quality of manufacturer production.Now answers are
.no it didnt happened again
i never go to this rpm before
yes the car was trying to speed but i pressed brake firmly.
it happened for just five seconds
