Wait, this isn't April 1st?
I imagine it'l be electric, will only drive 30% of it's stated "range" per charge, will come with a touch screen interface to change things like temperature, the lights etc and it won't work when it's cold.
I bet you have to charge the thing with a USB-C style lighting port.
I also imagine you'll have to take it to an Apple store to get it serviced by an Apple 'expert' who will just take it round back, shoot it in the face, and bring round a new one and charge you 599 for the privilege.
Also, since apple only do single 'buttons' (see their entire mouse range) It'l only have one pedal, and that just makes it go, BUT it'l have a multitouch interface that you can use toe gestures on.
