Guyz, i just wanna share u my great experience on my cultus vxl 2007 on isl-lhr motorway.I had done 155km/hr on petrol with AC,my car was loaded with my family and luggage. But thank God i didnt get caught by the police as they already caught a Lexus lx470 ,which had overtaken me swiftly....
BUt on CNG my car is not going beyond 120km/hr,why??
