Unlike the driver-only memory system in the M4, the RC F (except Track Edition) offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.
The RC F (except Track Edition)’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The M4 doesn’t offer an easy entry system.
The RC F’s standard power windows have a locking feature to keep children from operating them, but the driver can still raise and lower both of them with the lock engaged. BMW does not offer a locking feature on the M4’s standard power windows.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The RC F offers available headlight washers to keep headlight output high. The M4 doesn’t offer headlight washers.
To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the RC F has standard extendable sun visors. The M4 doesn’t offer extendable visors.
The RC F offers an optional center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable and it can provide a boundary between children. The M4 doesn’t offer a rear seat center armrest.
