The 2013 Mercedes-Benz SL550 Roadster is the kind of car that commands attention. Its sleek lines and powerful presence turn heads, drawing admiring glances and sparking conversations wherever it goes. Few vehicles possess the inherent magnetism of a bright red Mercedes-Benz convertible, and the SL550 embodies this captivating allure perfectly. Even those typically indifferent to automobiles find themselves drawn to its impeccable finish and sophisticated design. The SL550 isn’t just a car; it’s a statement, a rolling testament to luxury and performance in perfect harmony.
Exquisite Design and Roadster Appeal
The 2013 Mercedes-Benz SL550 Roadster immediately captivates with its classic sports car proportions. A long, sculpted hood flows gracefully from the iconic Mercedes-Benz tristar emblem, flanked by striking HID headlamps with distinctive LED accents. This powerful front end presence sweeps back over the optional 19-inch AMG five-spoke wheels, creating a dynamic and athletic stance. Hood vents, strategically placed before the steeply raked windshield, hint at the potent power beneath, often prompting inquiries about whether this is the high-performance SL63 AMG. However, the SL550 stands confidently on its own merits, offering a refined yet exhilarating driving experience that is distinctly Mercedes-Benz. The passenger cabin, designed for two, is nestled beneath a low-slung roofline, leading to a rounded, abbreviated rear deck that completes the car’s elegant silhouette.
Being a true Roadster, the 2013 SL550 features a power-retractable hardtop, a hallmark of Mercedes-Benz engineering. This sophisticated system operates with a seamless robotic ballet, transforming the car from a closed coupe to an open-air convertible in approximately six seconds. While top-down driving is a defining feature, practicality is also considered. Trunk space is intelligently managed; when the top is down, a cover ensures that luggage does not interfere with the roof mechanism. Despite this, there’s still ample room for a couple of carry-on bags and smaller items beneath the power-lift trunk lid. For situations where the top remains up, this cover can be conveniently moved, expanding the available cargo capacity significantly. Even accessing the trunk with the top down is a carefully orchestrated sequence, involving the automatic lifting of the trunk lid and the folded roof panels to provide access. This meticulous design ensures both the elegance of the convertible experience and practical storage solutions.
Luxurious and Comfortable Interior
Stepping inside the 2013 Mercedes-Benz SL550 Roadster reveals a cabin that is anything but cramped. Generous dimensions provide ample space for even taller occupants, ensuring a comfortable and relaxed driving experience. Motorized adjustments for the seats and steering wheel, complete with three memory positions and an Easy Exit function, personalize the driving environment. The Easy Exit system automatically slides the seat back and retracts the steering wheel when the door is opened, enhancing ease of entry and exit.
Thoughtful storage solutions are integrated throughout the interior. A small parcel shelf and storage compartments accommodate personal items, keeping them secure when the top is down. While a minor point, the placement of the cupholders further back on the center console might seem less than ideal for immediate reach, subtly suggesting that the SL550 experience is perhaps best enjoyed without distractions.
The SL550 Roadster is equipped with features designed to maximize open-air driving pleasure, even in less-than-ideal conditions. A motorized windscreen effectively reduces wind buffeting at higher speeds, while Mercedes-Benz’s Air Scarf system gently blows warm air onto the necks of occupants from the headrests, combating chilly air. Automatic climate control intelligently adjusts settings for top-down motoring, and heated and ventilated seats provide customized comfort in varying temperatures. With side windows and the windscreen raised, and the Air Scarf and heated seats engaged, the 2013 SL550 creates a cocoon of comfort, making top-down driving enjoyable in almost any weather. The remarkably low wind noise allows for easy conversation and hands-free calls even at highway speeds. Adding to the relaxed ambiance, multi-level massage seats and adaptive cruise control transform long drives into serene journeys. The Attention Assist drowsiness detection system is a subtle reminder to stay alert, even amidst the luxurious comfort.
For moments when a closed cabin is preferred, the SL550 transforms into a remarkably quiet coupe. However, even with the top up, the connection to the sky remains thanks to the optional Magic Sky Control. This innovative feature, a $2,500 option, is a transparent glass roof panel that blocks UV and IR light while allowing visible light to filter through. At the touch of a button, the glass can be made nearly opaque, providing shade and reducing glare. This “tint-on-demand” technology adds a touch of futuristic sophistication and draws admiration from passengers.
Potent Performance and Engaging Driving Dynamics
Beneath the sculpted hood of the 2013 Mercedes-Benz SL550 lies a 4.6-liter V-8 biturbo engine, a masterpiece of engineering. This powerplant combines direct-injection technology, a defeatable autostop feature, and an efficient seven-speed automatic transmission to balance exhilarating performance with reasonable fuel economy. While EPA ratings of 16 mpg city, 24 mpg highway, and 19 mpg combined may not rival economy cars, they are impressive for a vehicle producing 429 horsepower and 516 pound-feet of torque. The engine delivers power smoothly and effortlessly, making the SL550 equally adept at cruising city streets or unleashing its potential on open roads.
The standard suspension of the SL550 Roadster is undoubtedly capable, but the test vehicle was equipped with the optional Active Body Control (ABC) adaptive suspension, a $4,090 upgrade. ABC offers both Sport and Comfort modes, and goes beyond typical adaptive systems. At lower speeds, it can raise the car by about 2 inches to navigate obstacles. As speed increases, it automatically lowers the vehicle to reduce wind resistance and enhance stability. Simultaneously, the four dampers continuously adjust to optimize either responsiveness or ride comfort, depending on the selected mode and driving conditions. The Comand system display can visualize these adjustments, but the real reward is felt in the car’s refined handling and composed ride.
In Comfort mode, the 2013 SL550 is remarkably effortless. Its abundant power allows for relaxed city driving, maintaining low revs and smooth transitions. While ABC cannot eliminate every imperfection of urban roads, it effectively minimizes harshness. The autostop system, engaging at traffic lights and stop signs, operates smoothly, though a defeat button is readily available for stop-and-go traffic.
On the highway, the ride remains serene and quiet. The Econ shift program prioritizes fuel efficiency, sometimes requiring a moment for downshifts during passing maneuvers. Switching to Sport mode transforms the SL550‘s character. Gears are held longer, downshifts are more responsive, and the full force of the V8 engine is readily accessible. While Sport mode enhances handling, the adaptive suspension still maintains a comfortable ride. Steering-wheel paddles offer manual shift control, but the Sport program proves highly intuitive for most driving scenarios. Active seat bolsters, designed to provide lateral support during cornering, can be adjusted or deactivated based on driver preference.
For spirited driving, the SL550 truly shines on winding roads. Its balanced chassis, powerful engine, and responsive suspension create an engaging and rewarding driving experience. Stability control remains unobtrusive, allowing for confident cornering, while the sheer power is always available for thrilling bursts of acceleration.
Technology and Infotainment: A Mixed Bag
The 2013 Mercedes-Benz SL550 Roadster excels in many areas, but its infotainment system, particularly the Comand Online feature, presents a mixed experience. While the core Comand interface is familiar to Mercedes-Benz drivers, its complexity and slow operation detract from the otherwise refined cabin experience. Navigating menus, switching audio sources, and accessing features often involve excessive dial-twisting and scrolling. The system’s feature bloat, without a corresponding improvement in organization, contributes to this cumbersome user experience.
Voice entry for navigation is a redeeming feature, offering accurate address input. However, voice control functionality could be expanded to encompass more system features. Navigation with traffic data is standard, but lacks topographic or satellite imagery despite the data connection.
Audio sources are plentiful, including a six-disc DVD changer, iPod/MP3 interface, USB connection, SD card slot, SiriusXM Satellite Radio, hard drive storage for audio, and AM/FM radio with HD Radio. Bluetooth connectivity supports hands-free calling and audio streaming. The standard Harman Kardon Logic7 surround-sound system with FrontBass technology delivers impressive audio quality, creating a rich and immersive sound experience. For audiophiles, an optional Bang & Olufsen sound system further elevates the audio experience with increased power and enhanced components.
Comand Online, Mercedes-Benz’s connected services suite, is a key feature of the 2013 SL550, offering web-based services such as Google Local Search, News, Yelp, and Facebook integration. However, the system’s sluggish performance is a significant drawback. Loading times for menus and features are lengthy, making interactions frustratingly slow. The system’s slow response times and limitations while driving often make using a smartphone a more efficient alternative for connected services.
Google Search and Yelp integration offer useful point-of-interest search capabilities, but performance issues hinder their practicality. Facebook integration, while ambitious, suffers from the same slow load times, making status updates and interactions tedious. Inconsistent back button behavior within the Comand Online interface further adds to the frustration. Compared to competitors, Comand Online lags behind in speed and user-friendliness, and its limited integration with other vehicle systems diminishes its overall value.
Pros and Cons
The Good:
- Powerful and smooth V-8 Biturbo engine.
- Exceptionally quiet and comfortable top-down motoring.
- Comprehensive standard media sources and premium audio system.
The Bad:
- Slow and cumbersome Comand Online system.
- Steep learning curve for the physical infotainment controls.
- Predictably low fuel economy.
The Bottom Line:
The 2013 Mercedes-Benz SL550 Roadster is a superb luxury convertible, prioritizing driving pleasure and comfort over technological gimmicks. However, its Comand Online system falls short of contemporary standards set by competitors.
Conclusion: Is the 2013 SL550 Roadster Worth It?
The 2013 Mercedes-Benz SL550 Roadster is undeniably a brilliant machine. While the Comand Online system may be a weak point, it doesn’t overshadow the exceptional engineering and design of the vehicle as a whole. The sheer joy of driving this striking red convertible, with its potent performance and luxurious comfort, outweighs the technological shortcomings. For those who prioritize the visceral experience of open-air motoring, powerful performance, and timeless Mercedes-Benz luxury, the SL550 Roadster delivers in spades. Safety features, including Mbrace telematics, lane-keep assist, pre-collision warning, blind-spot monitoring, and a rearview camera, further enhance peace of mind. While the starting price is significant, the 2013 SL550 Roadster offers a feeling that transcends mere value, embodying the essence of a true luxury roadster and making it a compelling choice for discerning drivers.
