I know this isn’t exactly relevant to your enquiry but I test drove a standard petrol engined auto version back in December, it was showing an average mpg of 34.2?. It’s to be hoped the MHEV, in manual form, would be much improved on that figure.
Either way, I found it very unsettled, bouncy, and fidgety on the road, with plenty of understeer and extremely raucous on acceleration?. A huge problem for me(pain wise) was also the lack of lateral support on cornering but maybe these issues were as a consequence of me coming out of my X1, which has upgraded sports seats to gain side seat bolsters and four way lumber support.
We all have differing medical problems that necessitate many specific ride and seating requirements, meaning others may find it okay for them?.
