. SL Class R129 Information

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.

Visually and technically refreshed SL models were showcased at the Frankfurt International Motor Show in September 1995. The facelifted variants featured modified body styling, more comprehensive standard equipment and optimised engineering. The body styling had only been changed slightly, but redesigned front and rear bumpers, colourless glass covers on the front indicators and subtle changes to the radiator grill, now with only six slats, made the SL look even more dynamic. The side skirts and bumpers that were previously a contrasting colour were now body coloured and were fitted with the modified vents that were a distinctive feature of the facelifted models. Further new features were the bichromatic tail lights that appeared a uniform red and new, twelve-hole, alloy wheels that were fitted to all SL models as standard. A glass roof with sun-blind could also be fitted as an option instead of the usual aluminium hardtop. Inside, the door panelling, steering wheel and seat design had been modified.

In April 1998 at the Turin Motor Show, an updated SL range was presented featuring newly developed engines and a subtly revised design. The most significant refinements included the introduction of a new generation of V-type engines with six and eight cylinders to replace the six-cylinder in-line engine featured in the M 104 series and the M 119 series V8-unit. Thanks to the advent of 3-valve technology and dual ignition, the new engines consume up to ten percent less fuel than their predecessor models and are particularly remarkable for their very low exhaust emissions. Output levels range from 150 kW (204 hp) in the SL 280 and165 kW (224 hp) in the SL 320 to 225 kW (306 hp) in the SL 500. The top-of-the-range SL 600 continues to be powered by the M 120 twelve-cylinder engine producing 290 kW (394 hp). The SL 60 AMG was discontinued as part of the model improvement program and has not been available since June 1998. Continue reading...
