A Legacy of “Super-Light”: 60 Years of Mercedes-Benz SL
The debut of this sixth-generation SL coupe/roadster in 2012 was particularly significant, marking the 60th anniversary of the revered Mercedes-Benz SL lineage. Initially conceived as a simple abbreviation for “super” and “light” (super-leicht), the “SL” designation has evolved into the most recognized and celebrated model series within the Mercedes-Benz portfolio for six decades.
The genesis of the SL can be traced back to a purebred race car, a stark departure from the conventional sports/racing vehicles of 1952. The original 300SL race car was a marvel of engineering, featuring an innovative tubular space frame, a streamlined teardrop-shaped aluminum body, distinctive gullwing doors, and a pioneering direct-fuel-injection engine. This groundbreaking machine immediately captivated the motorsports world. Victories at prestigious events like Le Mans and the grueling Carrera Panamericana in its debut season solidified the 300SL race car’s legendary status.

To the surprise of many, Mercedes-Benz transitioned the race-bred SL into a production vehicle in 1954. The production 300SL Gullwing coupe was unveiled not at a European auto show, but in New York, marking the beginning of a lasting legacy of thrilling SL sports cars from Mercedes-Benz. Building on the foundation of the 300SL Gullwing coupe, the convertible 300SL roadster was introduced in 1957, further expanding the SL’s appeal. These two iconic models are often seen as spiritual predecessors to the modern-day SLS AMG gullwing and roadster variants. Mirroring today’s SLK (now SLC), the 190SL, a more compact and accessible convertible launched in 1955, was marketed alongside the exclusive 300SL, broadening the SL family’s reach.
The 2013 Mercedes SL550 Coupe: Redefining Performance and Efficiency
The 2013 Mercedes SL550 Coupe represents a significant leap forward, retaining the spirit of its predecessors while embracing modern engineering principles. The adoption of an aluminum body is a key highlight, contributing to both weight reduction and enhanced structural rigidity. This evolution ensures the Mercedes SL550 Coupe delivers both exhilarating performance and refined handling. While growing slightly in overall dimensions to enhance interior space and presence, the focus remained firmly on optimizing weight and agility. This meticulous approach to engineering underscores Mercedes-Benz’s commitment to pushing the boundaries of automotive design and technology.

Direct Injection V8 Engine: Power and Economy Combined
At the heart of the Mercedes SL550 Coupe lies a newly developed V8 engine that achieves a remarkable feat: improved fuel economy coupled with increased power output. This is an engineering triumph, as typically, enhancing either power or fuel efficiency often comes at the expense of the other. This advanced V8 engine incorporates direct fuel injection, twin turbochargers, and multi-spark ignition, all working in concert to deliver exceptional performance and efficiency.
Building upon the success of its 5.5-liter predecessor, the new 4.6-liter V8 engine in the Mercedes SL550 Coupe showcases a 20 percent reduction in displacement. Despite this downsizing, it generates even greater horsepower and torque figures – an impressive 429 horsepower and 516 lb.-ft. of torque. The seemingly paradoxical increase in power from a smaller displacement engine is made possible by the potent combination of twin turbochargers and an air-water intercooler, effectively compensating for the reduced engine size and boosting overall performance.
ECO Stop-Start System
Further enhancing fuel efficiency, the Mercedes SL550 Coupe engine is equipped with an innovative ECO stop-start system. This intelligent system automatically shuts off the engine whenever the car comes to a complete stop and the brake pedal is depressed, conserving fuel during idling situations. When the driver releases the brake pedal and touches the accelerator, the engine computer instantaneously identifies the optimal piston position for ignition. The direct fuel injection and multi-spark systems, working in conjunction with a robust starter motor, ensure a near-instantaneous and seamless engine restart, enhancing both fuel economy and driving refinement.
Innovative Technology for Enhanced Driving Experience
The Mercedes SL550 Coupe is not only about performance; it’s also packed with innovative technologies designed to elevate the driving experience to new heights.
