When Audi's new TT coupe hits European roads the vehicle will have the great style and performance it has come to be known for since its introduction.
But drivers will notice something different about the new version of this famous sports car -- better transient handling and road isolation along with increased driver comfort, and the ability to select the level of suspension damping with a console-mounted two-position driver preference switch.
Audi is equipping its new TT with Delphi Corp.'s MagneRide semi-active suspension -- an innovative technology that uses magneto-rheological fluid to provide continuously variable real-time suspension damping control. Named Audi Magnetic Ride on the TT, MagneRide responds in real time to road and driving conditions based on input from sensors that monitor vehicle body and wheel motion.
"Audi's work to bring 'Advantage Through Technology' allows MagneRide to enhance the TT's great handling and performance characteristics with increased ride comfort, greater vehicle body motion control and improved transient handling capability," said Daniel Warrell, Delphi Chassis Systems business line executive. "MagneRide will help make a great car even more purposeful and enjoyable."
Audi Magnetic Ride is based on a magneto-rheological principle. When in a magnetic field, small iron particles in the suspension fluid align themselves in the direction of the magnetic flux. The electromagnetic coil is integrated into the damper piston in such a way that when it is energized the magnetic flux runs exactly transversely to the admission ports in the damper piston. If the piston moves, the aligned iron particles create flow resistance in the flowing suspension fluid.
The greater the energy applied and the stronger the magnetic field, the greater the resistance and damping power. The energy is controlled in relation to driving dynamics and impulses from the road. This means for every road situation optimal damping power is available. This damping power produces -- according to OEM desire -- a more comfortable feel or sportier vehicle handling.
Audi uses the magneto-rheological dampers for both -- comfort and sport. In its basic mode, the suspension allows for a more comfortable vehicle feel. In sports mode, the vehicle offers a sportier ride thanks to a push of a button...
