The only thing I dont' like about it is the base styling of the 5-series. It's boring, and the interior is extremely busy, even if it doesn't look bad. But it does look look better than the previous model.
I am also disappointed that there is nothing hybrid/electric in the engine, at least an electric turbo to help with the lag (which I am sure will be present, they always say it's minimal but it turns out it's not).
Acceleration times are phenomenal. No more problems putting the power down at stop lights
I would say it could easily manage another 100hp, but half of this figure is probably reserved for the special edition models to boost slowing sales after a few years.
Also, from the videos it seems to me that the Active Sound is gone. Hopefully !
