The soft-top module is located behind the seats. It consists of the components roll-over protection system, soft-top, soft-top well and rear window compartment. The multi-joint hinge for the soft-top compartment cover, which is made of CFRP, is also part of the soft-top module.
The rear lid grille with the longitudinal alignment of slats in Black (high-gloss) visually highlights the new turbo technology.

Mercedes-Benz C 111 - III
Drag coefficient = 0.183
The signature side intake and floating C-pillar collects air to feed the mid-mounted engine and directs airflow over the rear deck to increase downforce.
The P88 rear suspension changes were also incorporated into the P87, allowing the use of wider Venturi tunnels.
Group C cars were capable of such high top speeds as they relied on ground effect aerodynamics to produce the required downforce. To further improve the ground effect efficiency, the P87 featured an extended wheelbase, allowing for longer tunnels.
