The 2007 Mercedes-benz Sl550 Roadster presents a compelling blend of potent performance and striking aesthetics, making it a desirable vehicle for those who appreciate open-top driving and sophisticated engineering. This iconic roadster, with its retractable hard top, makes a bold statement wherever it goes. While it boasts a powerful V-8 engine and advanced handling technology, a closer inspection reveals areas where it might not fully justify its premium price tag. Let’s delve into a detailed review of the 2007 SL550, exploring its strengths and weaknesses for potential owners and enthusiasts alike.
The heart of the 2007 Mercedes-Benz SL550 Roadster is its impressive 5.5-liter V-8 engine. This powerplant is shared with other notable Mercedes models of the time, delivering robust performance across the range. However, in the SL550, it truly shines, providing ample power for exhilarating drives. Complementing this potent engine is the inclusion of Active Body Control (ABC), a standard feature that sets the SL550 apart within the Mercedes lineup. ABC is an active suspension system employing a network of sensors and hydraulic servos to dynamically counteract body roll during cornering, acceleration, and braking. This technology is crucial in maintaining the SL550’s composure and agility, especially when pushed on winding roads. To evaluate this technology, a spirited driving test in San Francisco’s Presidio was conducted, comparing the standard ABC mode with the driver-selectable ABC Sport mode.
In standard ABC mode, the 2007 Mercedes-Benz SL550 Roadster exhibited competent handling, although it felt slightly less agile in quick transitions compared to rivals like the 2007 Jaguar XK. The steering was noted as somewhat numb, with a degree of understeer requiring more driver input than expected. However, engaging the ABC Sport mode significantly sharpened the SL550’s handling dynamics. Weight transfer during quick changes of direction became noticeably more responsive, and in aggressive cornering, the suspension actively resisted body roll, allowing the car to maintain its line with enhanced stability. While ABC Sport mode doesn’t alter throttle response, it contributes to a more linear acceleration feel, resulting in a smoother and seemingly quicker power delivery. The test concluded that ABC Sport mode was the preferred setting for maximizing the driving enjoyment of the SL550.
Stepping inside the 2007 Mercedes-Benz SL550 Roadster reveals an interior that prioritizes sporty functionality over opulent luxury. The cabin design leans towards a spartan aesthetic, dominated by black leather upholstery on the seats, dashboard, and door panels, contrasted with black plastic trim. While a touch of wood trim on the center console and optional wood accents on the steering wheel and shifter attempt to elevate the ambiance, the overall impression is somewhat underwhelming for a vehicle in this price bracket. For those seeking a more luxurious interior, Mercedes-Benz offered designo trim packages, which included upgraded paint, Nappa leather, a wood-and-leather steering wheel, a premium roof liner, and designer floor mats, albeit at a significant additional cost.
A standout technological feature of the 2007 SL550 Roadster’s interior is its retractable hard-top roof. Activated by a conveniently placed flap on the center console, the roof smoothly folds and disappears into the trunk in approximately 15 seconds, transforming the coupe into a true roadster. The test vehicle was equipped with the optional Panorama roof, featuring a glass panel that enhances cabin light and creates a more streamlined rear profile. Even with the roof stowed, the SL550 retains a usable amount of cargo space, further enhanced by a tilting shelf that automatically raises when the trunk is opened, improving accessibility.
Another notable interior feature is the dynamic multicontour seats, part of an optional package. These seats offer customizable shoulder width and lumbar support adjustments via controls on the side of the seat. Additionally, a “Pulse” feature is included to help reduce lower back fatigue during longer drives. These seats aim to provide personalized comfort and support, enhancing the driving experience for both occupants.
However, the technology interface within the 2007 Mercedes-Benz SL550 Roadster, particularly the Comand system, received criticism. The 6.5-inch color LCD screen, surrounded by plastic buttons, serves as the central hub for navigation, entertainment, and vehicle settings. The navigation system, standard in the SL550, was deemed less user-friendly compared to contemporary systems. Its non-touchscreen interface requires destination input via a four-way button cluster, which is described as slow and somewhat frustrating due to input lag and redundant confirmation prompts. Voice guidance volume adjustment was also found to be cumbersome. Furthermore, the map display quality was criticized for its low resolution and lack of street-name detail at closer zoom levels, and visibility issues in direct sunlight with the top down.
The audio system in the 2007 SL550 Roadster is a Bose Cabin Surround setup with eight speakers and a subwoofer. While it aims to deliver an immersive audio experience, sound quality was considered adequate but not exceptional. Bass reproduction could be muddy, and high frequencies occasionally sounded shrill. A significant drawback was the placement of the 6-disc CD changer behind the driver’s seat, making it inconvenient to access while driving. Furthermore, the absence of an auxiliary input jack or optional iPod adapter limited connectivity for external audio sources. DVD playback functionality was also restricted to audio only while driving, limiting its utility. Hands-free calling capability was also a point of contention. The standard phone cradle supported only a limited number of handsets, requiring an additional Bluetooth module purchase for broader compatibility. Even then, voice control for hands-free and audio functions was an extra-cost option.
Under the hood, the 5.5-liter V-8 engine of the 2007 Mercedes-Benz SL550 Roadster delivers a refined and potent driving experience. While not exhibiting immediate off-the-line explosiveness, the engine’s power builds strongly above 2000rpm, providing brisk acceleration. The ride quality is notably smooth and quiet, even with the top down at highway speeds, minimizing wind and road noise intrusion into the cabin. With the top up, the cabin becomes impressively serene, with only a subtle exhaust note during acceleration. The SL550 features a driver-adaptive 7-speed automatic transmission with manual shift override. The transmission’s adaptive programming aims to adjust shift points to match driving style, and it includes features like “Shift into Optimum Gear” for maximum acceleration or engine braking, and a “Comfort” mode for smoother starts and upshifts.
However, the fuel economy of the 2007 Mercedes-Benz SL550 Roadster is less than stellar. EPA estimates are 14mpg city and 18mpg highway, with observed fuel economy during testing aligning with the upper end of this range at 17.6mpg. For a two-seater roadster with its performance level, fuel consumption is relatively high.
In conclusion, the 2007 Mercedes-Benz SL550 Roadster offers a compelling package of performance, technology, and luxurious open-top motoring. Its potent V-8 engine, advanced ABC suspension, and striking exterior design are significant highlights. However, the interior design and materials, while functional, lack the premium feel expected at its price point. The Comand system and audio features also present usability and connectivity shortcomings. With a base price exceeding $94,000 and options quickly pushing the total over $100,000, the 2007 SL550 enters a highly competitive market segment. For similar money, buyers could consider alternatives like the BMW M6 or the Jaguar XK, potentially offering better value or different strengths. Ultimately, the 2007 Mercedes-Benz SL550 Roadster appeals to those who prioritize open-air driving, robust performance, and the prestige of the Mercedes-Benz brand, but a careful evaluation of its interior and technology is recommended alongside its price in comparison to competitors.
