The world premiere of the new 129 series SL in March 1989 belonged to the main attractions of the Geneva Motor Show. The new types 300 SL, 300 SL-24 and 500 SL showed no common features with their preceding models except for their overall concept. Just like 18 years before, when the 350 SL demonstrated a great number of innovative construction details in automotive progress, the 129 series SL now also was a completely new car.
The new SL generation convinced by a harmonic and very successful stylistic shape. It expressed dynamics, sportiness, but also comfort and elegance. On the one hand, the design presented itself traditional, on the other hand, its new solutions of many details looked far into the future. Thus, for instance, the radiator grill, the legendary trade mark of the SL models, had been newly interpreted on the basis of remaining traditional shapes. In contrast to the preceding types, where the broad chrome frame and the star were dominant, the radiator cowling was now organically integrated into the engine bonnet. The star, now the only chrome decoration of the car, had been completed by horizontal lamellas of anodized aluminium.
Considerable improvements as to passive safety could be achieved in comparison to the preceding models. With high efforts in development the exemplary safety standard of the saloons and coupés could also be reached in the SL. Since there was no normal roof unit, a basically different body structure and therefore an intensive development work was demanded. The envisioned impact-resistant passenger compartment was achieved by combining several structural elements. Included were, first of all, a specially stiff body platform with high-strength metal sheets, large supporting elements as well as flexural resistant transitions from the A-pillars and the rear side parts to the frame side rails. The doors played a decisive role. By a well-devised bead of the door shell inner panel they functioned as a pressure resistant link between the front wall pillar and the centre pillar. Thus they contributed to preserving the survival space in case of a collision.
A further point of development was the realisation and development of the forward structure, already well-proven in the saloon range. It was based on the fact that front-end impacts are often offset. By reinforcing the front end cross-ties, the side farther away from the front crash is now able to absorb part of the impact energy.
An integral part of the safety concept was the automatic rollover bar. It had been realised in car manufacturing for the first time. Its task was to secure the survival space of the passengers in case of a rollover. In order not to spoil the joy of driving in an open car by a fixed and inflexible rollover bar, a flexible solution was realised. Now the rollover bar is only activated in case of need. During the rest state the safety bar, consisting of a U-shaped high-strength steel pipe clad with PU-foam, was positioned in front of the folding-top compartment. It formed the end of the tail and was in one line with the folding-top compartment lid. In case of an imminent rollover the rollover bar was released by an electromagnatic sensor system. It folded up within 0.3 seconds by the force of prestressed springs and was secured by ratchets. The high-strength centre pillars served as basis for fixing and support. They were extensively linked with the rear frame side rails. In addition to the automatic „crash-triggering“ in case of need, there was also a manual operation. If desired by the driver, it could be activated by a switch. For this „comfort operation“ the folding up and the retracting was regulated by a hydraulic element.
But the survival space in case of a rollover was not only secured by the rollover bar. It was also supported by a special construction of the A-pillars. They consisted of high-strength metal sheets and were reinforced with high-strength tubes at the area of the upper door edges. Together with a two-tray front roof frame and a windscreen bonded with the body a very high stability was reached even if force was applied on one side only.
The four-valve version of the 3-liter engine as used in the 300 SL-24 was a new development based on the M 103. The 4-valve cylinder head and the camshaft adjustment were new. Combined with higher compression and electronic ignition with anti-knock control the 4-valve engine (M 104) had a power output 40 hp higher than that of the M 103. This meant that the 300 SL-24 had a significantly better performance than the 300 SL with almost identical fuel consumption, however, the price of the car was almost DM 10,000 higher.
