G90/G99 M5

Hybrid Power, Redefined by Keller Performance

The all-new BMW G90 M5 uses a powerful S68 twin-turbo V8 combined with electric hybrid assistance. While the platform provides immense potential, factory software and exhaust routing limit airflow, cooling efficiency, and overall power delivery.

Keller Performance engineers upgrades specifically for hybrid-compatible tuning and thermal control.
