In my experience with sport mode Robin, anything more that a slight touch of the throttle and the gearbox will change down to get the revs above 1500rpm. You need to be in manual only to feel what I describe, though I think you have a different variation of the engine, as well as the gearbox, though then again it could just be my car. In my car in manual mode it won't let you change up to 7th until you're at a speed where the revs would be above 1300rpm, so you can only really experience it in 3rd to 6th gears.
In E mine spends a lot of it's time below 1500rpm also, but at a cruise. If i want to increase my speed by more than 1mph/sec it usually changes down.
In manual it feels like an old school petrol turbo car, albeit at a lower rpm.... I.E. foot to the kickdown point at 1100rpm = nothing, nothing, nothing, nothing.....1500rpm and allllllll of the torque. I sometimes wonder whether mine has been re-mapped by a past owner, as it feels like you get full turbo pressure at 1500rpm, when most factory maps in other cars progressively increase boost in the early part of the rev-range(although I only have experience of petrol turbo cars). It's forever having to use the ESP to limit power in the wet when it comes on boost as it's such a big dump of power at once.
Are your cars more linear with the way the power comes on 1000 to 1500? Mines Linear after the initial dump of power.
Don't get me wrong, I love it like it is, it's exciting. I prefer any turbo car to give full-boost from whatever point the engineering allows, rather than a computer feeding it in progressively for a more linear (and boring IMO) powerband.
I must admit I rarely use manual but I have not noticed any drop or lack of power band.
Mine is 265 bhp with the 9g box.
I’m out and about tomorrow so will put car into manual and try it out.
Mind you I’m not a fast driver normally but I do like to give it a blast when there is a nice bit of open road.
