We can only speculate, but my feeling it it would be on the lower end more like the Chevy volt although there might be a higher end model. HOWEVER at this point its scarcely even in the rumor state!
I'm not sure where this is all going to fit. Apple is very premium in the tech market, so I could figure them fitting in the Acura (upscale, not luxury) price range, but as a car guy I wouldn't be surprised if this never gets made as a fleet car.
