Auto Motor und Sport is reiterating that "98%" figure. The bodies of the concept cars (Sportback as well as Avant) are allegedly identical to those that we will be seeing on the serial production examples. Alterations will, however, will appear on elements such as aprons, rear diffusor and lighting units, front and rear. The fascia shield (grill) will be somewhat shallower as will the intake/projector cavity. Door handles (or flush opening cavities) will be added. Conventional rearview mirrors will be standard, cameras optional. Exterior dimension specs of the concept cars will reportedly remain unchanged (4960-70mm L, 1960-65mm W, 1440-45mm H). Rim sizes will range from 19" to 21", with a 22" option quite possible.
