Detailed Explanations
2013: First Year of the R231 Generation
The 2013 SL550 marked the beginning of the R231 generation, a significant departure from its predecessor. This model boasted a lighter aluminum body, contributing to improved handling and fuel efficiency. The innovative Magic Sky Control roof, allowing drivers to adjust the roof's transparency, was a standout feature. The standard V8 engine provided ample power and a refined driving experience. However, being the first year of a new generation, it's susceptible to early production issues.
2014: Minor Interior Updates, Improved Infotainment System
The 2014 SL550 received minor interior refinements and an updated infotainment system, addressing some of the initial criticisms of the previous year. While largely similar to the 2013 model, the infotainment improvements offered a slightly more user-friendly experience. However, it still carries the potential for similar early-generation issues.
2015: Enhanced Safety Features
The 2015 SL550 saw the introduction of enhanced safety features, notably Collision Prevention Assist Plus. This system provided added peace of mind by helping to mitigate potential accidents. Beyond this, the model remained largely unchanged, inheriting the strengths and weaknesses of the previous two years.
2016: Aging Electronics
The 2016 SL550 represents a year with no major updates, essentially a continuation of the existing features and design. As the model gets older, potential maintenance costs may increase, particularly related to aging electronics. While reliable overall, the car's age should be considered when evaluating its long-term ownership.
2017: Facelift with Updated Styling, 9-Speed Automatic Transmission
The 2017 SL550 underwent a significant facelift, featuring updated styling both inside and out. The most notable change was the introduction of a 9-speed automatic transmission, replacing the previous 7-speed. This resulted in improved performance and fuel economy. However, the more complex electronics and advanced technology could potentially lead to higher repair costs.
2018: Enhanced Driver Assistance Systems
The 2018 SL550 built upon the 2017 facelift with enhanced driver assistance systems and more customizable options. These additions further enhanced the driving experience and safety. Similar to the 2017 model, the advanced technology could mean higher repair costs should issues arise.
2019: Final Year of the SL550 with the V8 Engine
The 2019 SL550 marked the final year of production for this model with the V8 engine, making it a potentially desirable collector's item. Production numbers were limited, potentially leading to higher prices on the used market. Like the 2017 and 2018 models, it shares similar maintenance concerns related to the more complex technology.
