Stuttgart. Fifty several years back, in April 1971, Mercedes-Benz initiated a new chapter in the intriguing record of the SL sporting activities automobile: the 350 SL was the brand’s to start with SL with a V8 engine and the to start with model in the R 107 product collection to bear the “R” abbreviation for “roadster” for the very first time.

In 2021, the brand name with the star is continuing its tradition of SL sports vehicles by launching the Mercedes-AMG SL in model series R 232.

A product for achievements with 18 years of collection manufacturing

The R 107 was developed from 1971 to 1989, in the course of which time it was saved up to day with standard facelifts and new engines. With the exception of the G-Course, no other Mercedes-Benz has been created for lengthier. Technically speaking, the Mercedes-Benz 350 SL launched 50 years in the past had small to do with its immediate predecessor, the W 113 “Pagoda” SL. In its place, the designers forged a lot closer back links to the brand’s current passenger car or truck variety of the time: the entrance and rear suspension systems, for example, were being primarily based on the “Stroke/8” models of the higher medium-measurement group. The 147 kW (200 hp) V8 engine with a displacement of 3,499 cc was a have-around from the premium-course Mercedes-Benz 280 SE 3.5 of the W 111 product collection (coupé and cabriolet) and the W 108/109 model series (saloon).

In 1973, the 165 kW (225 hp) 450 SL, also with an eight-cylinder engine, that experienced in the beginning been reserved for export to North The united states from autumn 1971, appeared on the European marketplaces. In 1974, the six-cylinder 280 SL (136 kW/185 hp) model adopted. For the first time in the record of the SL, this meant that a design collection was now readily available with a alternative of a few diverse engines.

As a result of the 1980 facelift, the 380 SL (160 kW/218 hp) replaced the 350 SL, and the 500 SL (177 kW/240 hp) took about the place as the leading product in area of the 450 SL. As aspect of the in depth overhaul, the inside of the sports activities automobiles, among other factors, was adapted to match the S-Course Saloons of the 126 model collection.

The 420 SL (160 kW/218 hp) was a absolutely new addition, even though the 500 SL (180 kW/245 hp) was given a redesigned engine with an electronic ignition process and the Bosch KE-Jetronic electronically managed mechanical gas injection procedure.

All the products had been now presented with a closed-loop a few-way catalytic converter.
