In corners, all-wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Lexus RC F is not available with all-wheel drive.

Car and Driver

The AMG C-Class Coupe offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The RC F doesn’t offer a heads-up display.
