I said b/w 170 to 180 kph and not 180 kph!yes, i am an automobile engineer and i have heard of overdrive. also, i completely agree to what you said. and thats what even i meant that top gear is for cruising.
so even if the 5th gear in safari is "derestricted", it wont go till 180 kmph. are you trying to say that the safari will challenge the honda CRV in top speed?
why should TATA restrict it to 2500 rpm without any reason?
Do you have any idea what speed Safari is doing when its restricted at 2500 rpm in 5th with some more juice still left? Approximately 150 kmph.
Derestricted, the tacho goes up to 2800-2900 rpm and you what speed that equates to in 5th gear... b/w 168 kmph to 174 kmph.
