The Mercedes-Benz SL class has always been synonymous with automotive elegance and prestige. Each generation reflects the spirit of its time, and the R107, introduced in 1971 to succeed the W113 “Pagoda” SL, was no exception. This model family, including the iconic 1972 Mercedes 350sl, enjoyed a long production run until 1989, a testament to its enduring appeal as a luxury convertible.
The R107 marked a significant milestone by introducing a V-8 engine to the SL lineup. This was a necessary upgrade, considering the car’s substantial weight of around 3400 pounds. The design was characteristically Mercedes – conservative yet stylish, with a nod to the previous “Pagoda” roof models, although the R107 appeared larger despite similar dimensions.
The 1972 Mercedes 350SL holds a unique place in this history. While designated as the 350SL, aligning with European nomenclature, it was actually powered by a robust 4.5-liter V-8 engine in the North American market. This fuel-injected, overhead cam V-8 produced a healthy 230 horsepower, paired exclusively with a three-speed automatic transmission. The 1972 350SL boasted a fully independent suspension and standard four-wheel disc brakes, showcasing Mercedes-Benz’s commitment to engineering excellence.
In a move that would cause a slight name change, 1972 also saw the model redesignated as the 450SL for subsequent years. Furthermore, horsepower ratings were revised to SAE net figures, resulting in the 450SL being listed at 190 hp. The following year, 1973, brought about the implementation of large, federally mandated safety bumpers, front and rear, altering the car’s aesthetics. By 1975, stricter emissions regulations led to a further reduction in output to 180 hp with the introduction of a catalytic converter.
1976 marked the adoption of continuous fuel injection and transistorized ignition in the SL. In 1978, automatic climate control and stylish 14-inch aluminum wheels became standard, enhancing both comfort and visual appeal. Despite revisions to the fuel injection system in 1980, which further reduced power to 160 hp, the 450SL remained a popular choice.
The 450SL era concluded with the 1980 model year, paving the way for the 380SL in the 1980s. However, the 450SL, with its annual average production of around 6,000 units and strong reputation, remains readily available today. These cars are celebrated as comfortable and stylish open-top cruisers, and the 1972 Mercedes 350SL represents the genesis of this beloved V8 chapter in the SL story.
