For over 22 years BMW has been producing various vehicles at the only US location in Spartanburg, South Carolina. In addition to currently making X vehicles and of course the plug in hybrid X5 xDrive40e (1,200 mile review here) there is a Performance Center, where customers can take deliver of their new vehicles, experience other vehicles or simply take a driving school. (There is a really popular Teen Driving School there too).
Perhaps someone at BMW NA saw my AutoX video and decided to add a pair of i3 REx to the fleet to see how they will do. I would have of course chosen a BEV for the fun of the track, but knowing that REx sells at about 70% rate, it makes perfect sense to have them.
Although not fully advertised, you can try to ask your dealer if you can have the BMW 101 experience at the South Carolina Performance Center. It would probably need to coincide with a recent or a future purchase, but at least you can inquire.
The program typically includes:
Orientation Braking test/lesson Auto Cross (AutoX) DSC Review M Vehicle Hot Lap Factory Tour X5 off Road Tour Delivery of your vehicle - if course you can make it back in that BEV, REx, iPerformance, to your home.
