What materials are used in the construction of the BMW M4 body?

The BMW M4 body utilizes a combination of lightweight materials, including high-strength steel, aluminum, and carbon fiber-reinforced plastic (CFRP). The roof, for example, is made entirely of CFRP to reduce weight and lower the center of gravity.

What is the drag coefficient of the BMW M4?

The BMW M4 has a drag coefficient (Cd) of 0.34, which is optimized for aerodynamic efficiency. This is achieved through features like the Air Curtains, Air Breathers, and an aerodynamically designed underbody.

How much does the BMW M4 body weigh?

The curb weight of the BMW M4 varies by model and configuration but typically ranges from 1570 kg (3461 lbs) to 1640 kg (3616 lbs). The use of lightweight materials like CFRP helps keep the weight lower compared to similar vehicles.

What is the ground clearance of the BMW M4?

The ground clearance of the BMW M4 is approximately 120 mm (4.7 inches), which is designed to balance performance and everyday usability.

Are there any specific maintenance requirements for the CFRP components?

CFRP components, such as the roof, require careful handling and maintenance. Avoid using abrasive cleaners or tools that could damage the surface. Regular inspections for cracks or damage are recommended, and repairs should only be performed by certified BMW technicians using genuine parts.
