Very frankly I didn't feel any difference in leg space. The B11R I feel was a little more silent but when you are travelling in the first row, the engine noise is typically at a bare minimum. Even suspension noise would be nil on the butter smooth NH4.@f1fan, Thanks a ton for your valuable insight. So you are suggesting that the front row seats on the B11R from VRL should be the best bet in terms of leg space ? Also, Did you actually feel any difference between B9R and B11R w.r.t front row seats space, engine noise and suspension ?
Once while travelling from Mangalore to Mumbai on a SRS Scania, there was a lot of noise from the front suspension but once we touched Hubli bypass, that sound too reduced to a bare minimum due to good roads.
