I'm assuming the u/d/l/r will control all vehicle functions through the LCD display. The Nav & Radio are Sync 3, which uses a touchscreen (below). They chose to use a very small screen to save weight.
The interior will be heavy on the naked CF. Weight, weight, weight. Alot of the CF paneling on the inside is the CF tub itself. Probably gonna be a little more available in terms of interior customization than last time, but that's not a high bar to clear.

A few additional buttons. Start, Hazard, lift, aero and LC.
