17. Novelties

18. Dual Mass Flywheel DMF Technology at a glance
Technical requirements:
Higher torque levels
Higher ignition pressures
Stricter emission controls
Greater requirements for comfort and noise control
Protection of gearbox and vibration-sensitive vehicle components
all require extremely high-performance torsional dampers
