The Mercedes-Benz SL lineage is rich with iconic models, and while recently encountering a 1975 Mercedes-Benz SL, my reaction was notably different compared to when I had the opportunity to photograph the earlier W113 generation, famed for its distinctive “pagoda” roof. The R107 series, produced from 1971 to 1989, achieved the highest production numbers within the SL family, exceeding 230,000 roadsters (Pattni, 2024). However, it’s arguable that this generation’s design represented a step away from the design purity of its predecessor.
A key factor influencing the design direction of the 1975 Mercedes-Benz 450 SL was the decision to develop its chassis concurrently with a longer-wheelbase 2+2 coupe variant, the SLC. This strategy, intended to broaden market appeal by including a four-seater option, seemingly led to design compromises that arguably detracted from the individual strengths of both models.
The SL appears somewhat visually compressed, while the SLC exhibits an elongated aesthetic. This outcome suggests the challenges inherent in attempting to harmonize too many shared components across distinct vehicle types. The SLC essentially began as an SL, subsequently modified with a fixed roof and an extension of nearly 14 inches added to the wheelbase, primarily behind the B-pillar (Spencer, 2011).

Exterior Expansion, Interior Contraction
To my eye, the 1975 Mercedes-Benz 450 SL’s proportions seem somewhat unbalanced, a perception partly driven by the doors appearing disproportionately long relative to the 97-inch wheelbase. Conversely, the SLC’s rear section appears visually awkward, characterized by an overly flat rear deck, substantial C-pillars, and doors that seem too short for the car’s 111-inch wheelbase.

While the 1975 Mercedes-Benz 450 SL’s styling achieved a degree of visual coherence surpassing that of the SLC, the sleek lines of the W113 were replaced by a more substantial collection of early 1970s Mercedes design elements. Prominent among these were the expansive, wrap-around ribbed taillights, a defining characteristic of the era.
The R107 generation, including the 1975 Mercedes-Benz 450 SL, conveys an impression of increased size. It was surprising to discover that the actual exterior dimensions remained relatively close to those of the W113. The new design extended the length by three inches, broadened the width by one inch, and incorporated a wheelbase stretched by 2.5 inches. The height was reduced by half an inch.
Despite the increased bulk, the 1975 Mercedes-Benz 450 SL offered reduced interior space compared to the W113. Shoulder room decreased by an inch, and trunk capacity diminished by three cubic feet. The track width also narrowed by at least an inch, contributing to a less athletic stance compared to the W113. Even the drag coefficient experienced a slight increase, moving from 0.42 to 0.45.
The weight of the 1975 Mercedes-Benz 450 SL increased by approximately 500 pounds, a change partially attributed to the shift in U.S. models from an inline-six engine to a V8. Price points also saw a significant rise, escalating from the mid-to-high $7,000 range in 1971 to over $10,000 in 1972, the initial full sales year for the R107 in the United States.
The featured 1975 Mercedes-Benz 450 SL model carried a list price approaching $18,000. This positioned it just slightly below Mercedes-Benz’s entry-level full-size sedan, the 450 SE, highlighting its premium market positioning.
Design Nuances of the 1975 450 SL: Interesting Yet Not Iconic
The 1975 Mercedes-Benz 450 SL incorporated several noteworthy design elements, such as the ribbed rocker panels, adding a touch of visual texture and distinctiveness. It’s also notable how the Mercedes design exhibited considerably less lower-body curvature compared to American sporty coupes of the same era. This design choice likely contributed to reduced road debris and mud spray originating from the wheels.
The removable roof design of the 1975 Mercedes-Benz 450 SL offered a subtle nod to the downward-curving roofline of the W113. However, the quarter windows, featuring an upward kick at their base, introduced a design detail that arguably lent the R107 an appearance of being somewhat unfinished. Elevating the beltline at the C-pillar might have yielded a more refined aesthetic and potentially enhanced the visual harmony of the SLC variant even further.
It’s important to maintain perspective when evaluating the R107. The 1975 Mercedes-Benz 450 SL represented a significantly more sophisticated and interesting design compared to the offerings emerging from Detroit automakers during the early 1970s. Furthermore, succeeding the iconic W113 “Pagoda” roof SL was undoubtedly a formidable challenge for any design team. Nevertheless, my primary impression upon photographing this particular 1975 model was a sense of slight disappointment, considering the esteemed lineage it represents.
The overall visual impression of the 1975 Mercedes-Benz 450 SL leans towards “ponderous” rather than “lithe.” While federally mandated bumper regulations undoubtedly influenced the design, they cannot be solely attributed to this aesthetic shift. Mercedes-Benz design language, during this period, appeared to be transitioning towards a heavier, more tank-like visual vocabulary.
