I have Mehran and done about just 1,800 Kms (just first inspection is done so far). Problem is that its Engine produces alot of noise and very less gear ratio. For example on 2nd gear usually Mehran easily goes upto 40Km/h but for my car just at 30km/h it start producing so much noise that it seems as gear limit is reached and I change the gear. The pick and acceleration is perfect, just this loud sound and short gear ratios are my concern.
I have also tested it by running on Petrol. What could be the reason for this? Since its a new car so I early shift the gear, like if it produce so much noise at 30km/h then I engage 3rd gear to prevent engine from over revs.
As a reference to gear ratios check this vid:
