Re: T-Jet mileage.. not impressed Surya Few times crossed 100/110 Kms for a minute or so. Otherwise on highway drove around 80/90 Kms whenever it was possible. On ghat roads speed was around 20 to 50 Kms depends upon the stretch and conditions of the road. Averge speed was 45.2 Kms Yes. We our family enjoyed the trip and I enjoyed the long drive.
