The seventh-generation BMW M5 (G90) introduces a hybrid-assisted 727 hp powertrain, redefining performance in the executive sedan segment. With this increase in power and weight, suspension tuning becomes a crucial area for enhancing vehicle dynamics, ride quality, and driver confidence.

Engineering Overview: KW Variant 4

KW Suspension has developed the Variant 4 (V4) coilover system specifically for the BMW M5 G90 Sedan. This high-performance suspension upgrade offers advanced tunability and real-world usability for drivers who demand both comfort and control—particularly under the varied driving conditions found across the UAE.

• Rebound damping (16 clicks): Adjusts how the vehicle settles and responds to directional changes.
  
• Low-speed compression (13 clicks): Fine-tunes body motion during steering, braking, and acceleration.
  
• High-speed compression (13 clicks): Controls quick suspension movements from uneven surfaces or sharp impacts.

This separation of damping forces allows precise tuning for road feedback, ride comfort, and chassis balance, based on individual preferences or use cases.

Designed for the G90 Platform

With the added mass and complexity of its hybrid system, the G90 M5 benefits from a suspension solution capable of managing weight without sacrificing composure. The KW V4 system is engineered to meet this challenge:

Lowering Range:
Front: 15–30 mm
Rear: 10–30 mm

This offers a more aggressive stance while maintaining practicality for everyday driving.

Construction Materials:
Stainless steel struts (inox-line) and aluminum components offer high strength, corrosion resistance, and durability in the region’s harsh climate.

Compact Valve Design:
Eliminates the need for external reservoirs, simplifying installation and preserving usable space.

Electronic Integration:
Includes a cancellation module for the factory Electronic Damping Control (EDC) system, allowing seamless operation without fault codes or system errors.

Driving Characteristics
Drivers can expect a noticeable improvement in composure and responsiveness, both at low speeds and during high-speed cruising. The V4 system reduces unwanted body movement, sharpens steering feel, and maintains comfort on long drives—even when road conditions vary.

This makes the KW V4 particularly suitable for the driving environments found across the UAE, from smooth highways to more dynamic driving scenarios.
