At the 1989 Geneva International Motor Show, Mercedes-Benz presented the SL of the R 129 model series (1989 to 2001). The brand hit the mark once again with this vehicle: production capacities were soon exhausted, giving rise to waiting periods of several years. This SL set new standards in safety. The open-top vehicle performed sensationally in the stringent Mercedes-Benz frontal and rear impact crash tests. Integral elements of the concept were automatic, sensor-controlled rollbars which shot up into position within 0.3 seconds when the vehicle threatened to overturn and integral seats which were able to withstand forces far in excess of those which might occur in a collision.
