Thanks for extremely informative replies. Unfortunately a torquey diesel is out of the question, conscience can't justify the pollution. A petrol BMW is expensive to run, and I don't quite trust BMW reliability to opt for a first generation hybrid. To be honest, I'm doing less and less city driving, most of it will be long distance. And I do like a quiet refined drive. @ganzoom Thanks for the video, that looks plenty fast enough for me. I don't need to leave tyre scorch marks, just to be able to comfortably get up to speed in time to slow down for the next traffic light/traffic jam.
Thanks @Fujifan thats the kind of distance I'll be doing so good to know it can do that in comfort. @rayaans thanks, 30mpg flooring it in sport mode sounds pretty good to me. @Zotto thanks for that explanation, I need to get my head around what a cvt gearbox actually feels like, but yes the instant torque from the electric motor would probably compensate slightly for the diesel torque.
