@caseyliss @marcoarment re the BMW i4. My neighbour has the single motor M40, and I test drove the M50. The single motor is the way to go if you want BMW like handling. The dual motor just adds such a lump to the front, great in a straight line, so much worse around corners. A lot of the reviews on launch said a similar thing.
Speed difference to 60 is about 1.2secs but 210lb of extra weight over your front axle. Like having Muhammad Ali (at his prime) sat on your hood (bonnet).
