Went to Mahabaleshwar - Panchgani in my Logan last week end. Really enjoyed the drive on the Mumbai - Pune express way. This was my first experience of a long drive in my logan. Few observations about my Logan:

1) Quite stable even at 140kmph. Pushed it further to 150kmph but only for a short time. And I could feel that I have reached the limit.

2) Did not bother much about fuel efficiency. As this was my first long drive I wanted to speed a bit. But roughly I got about 14kmpl with Ac on about 70% of the time approximately.

3) When ascending the hills I could feel that the car was a bit under powered.

Number 1: You should be able to push it till 160 kmph. However only in case if you feel safe and have control on the drive and the road allows. Very rarely this happens. I have pushed it once for a stretch of some 20 kms may be. Around 130 - 140 kmph it is extremely stable as you rightly mentioned.

Number 2: Standard figures. Not high and not low too.

Number 3: Very true, but only in case where you are carrying some 4 or more passengers and with A.C. on. Put the A.C. off it should be OK. Or ask all but 2 passengers to climb on feet rather, then also it shall be OK.

My vehicle has done only 250 Kms.. Can i take it to around 120-140 levels.. is it ok..

DOnt! 90-100 it is

let it cross some 800 kms mark.

however some may want to push it only after first 1500 kms.

Well i went for a road trip to Kerela and the drive was awesome, i went to munnar and then thekaddy and back to bangalore, the thekkady to bangalore drive was awesome on NH7. i was able to touch 150kmph for the first time and the car felt good, it didn't go beyond that, Ac was on also 4 passengers.

On Nh7 i was able to cover 340kms in 4 hours, though it is still under construction and all toll roads have not been set up.

the entire trip was awesome, it took me 9 hours 20 minutes to reach munnar from bangalore and thekaddy to bangalore took 9 hours. 1 hour break was there for each trip.
