For historical reasons iOS was very inflexible in regards to the screen resolution. To increase the resolution they had to double the resolution (known as retina). So iOS Car will not support all iOS apps. Well you don't want to play e.g. "Flappy Bird" while driving a car anyway ;) As the bottom "info/command bar" is part of the screen, maybe the remaining area that is available for apps has the same ratio as older iPhone devices.
