This is from the Sochi F1 circuit day (open to all). He VBoxes at around 6:33.
0-100 3.56s
0-200 11.47s
Positives: Very grippy for a big car, predictable on the limit, easy to drift, probably the best compromise between comfort and performance
Negatives: Engine lacks punch until high revs, ceramic breaks are poor, seats are form over function (sliding all over in turns)
BMW refused permission for all the other participants to VBox (weirdly). This is the only VBox from the day.
