The Mercedes Benz SL series has a rich history dating back to the mid-1950s with the iconic 300SL “Gullwing.” Known for its “Sports Leicht” (sports lightweight) designation, each SL model has aimed to blend performance with luxury. The 2003 Mercedes Benz Sl 500 continues this tradition, offering a compelling mix of power, sophisticated features, and open-top driving pleasure.
The Legacy of the SL Roadster
The SL lineage began with the legendary 300SL Gullwing coupe, famed for its upward-swinging doors. Shortly after, a convertible variant joined the lineup, cementing the SL’s status as a desirable sports car. The “SL” moniker, short for Sport Leicht (Sport Lightweight), combined with engine displacement numbers like “300” (3.0-liter), signaled Mercedes-Benz’s intention to deliver both sporty performance and refined luxury. The 300SL was groundbreaking for its time, being the first production car with fuel injection and capable of reaching speeds up to 160 mph with optimized gearing – remarkable for a six-cylinder engine vehicle of that era.
Over subsequent decades, the SL evolved, generally becoming more luxurious and substantial with each redesign. The 1960s saw the introduction of the 230/250/280 SL roadsters. A significant shift occurred in the early 1970s when a V8 engine replaced the inline-six, a version that persisted through the 1980s and even gained popular culture recognition as the car driven by Steve Austin in “The Six Million Dollar Man.” The 1990s brought another generation, the sleek 300/320/500/600SLs, reintroducing six-cylinder engines alongside V8 and V12 options. The 2003 SL model we’re focusing on here is part of the newest generation at that time, upholding the core values of an open-air, two-seat grand touring (GT) car synonymous with Mercedes-Benz: luxury, safety, and capable performance. While the 2003 SL 500, weighing around 4,000 pounds, might not be considered lightweight in the original “Leicht” sense, this weight gain is attributed to the incorporation of advanced technology for handling, safety, comfort, and the addition of a retractable hardtop.
2003 SL 500: Models, Trims, and Available Options
In 2003, the SL series launched with two primary models: the SL500, powered by a 5.0-liter V8 engine, and the high-performance SL55 AMG, equipped with a 5.4-liter supercharged V8. The V12-powered SL600 was slated to join the range shortly after. The standard SL500 was generously equipped, featuring luxury, safety, and convenience features expected of a Mercedes-Benz. These included xenon headlamps, a Bose audio system with a CD changer, a navigation system (using CD-based media), electronic stability control, electronic braking, and the TeleAid communication service for emergencies and assistance.

The SL55 AMG took performance and aesthetics up a notch, boasting 18-inch alloy wheels, enhanced braking systems with eight-piston front calipers, distinctive sport seats and instrumentation, unique lower body styling, and quad exhaust outlets.
For buyers seeking personalization, Mercedes-Benz offered a range of options for the SL500. The Sport package allowed SL500 owners to emulate the SL55’s sporty appearance with 18-inch AMG wheels, performance tires, and lower body enhancements. Additional standalone options included Parktronic, an electronic parking assist system; bi-xenon headlamps for improved visibility; and ventilated seats with a massage function for enhanced comfort. Cutting-edge technology options included “Distronic” cruise control, a radar-based system maintaining a set distance from vehicles ahead, and “Keyless Go,” a keyless entry and ignition system using a card-like device.
Engine and Performance of the 2003 SL 500
The 2003 SL 500 retained the robust 5.0-liter V8 engine from its predecessor. This engine is a significant asset, producing 302 horsepower and 339 lb-ft of torque while meeting stringent emissions standards (projected to achieve Ultra Low Emission Vehicle status). While a manual transmission wasn’t offered, the five-speed automatic transmission incorporated Mercedes-Benz’s TouchShift system, enabling drivers to manually select gears for a more engaging driving experience. Performance figures for the SL500 were impressive, with a 0-60 mph acceleration time of 6.1 seconds and an electronically limited top speed of 155 mph, indicating its grand touring capabilities.

For those desiring even greater performance, the SL55 AMG’s supercharged V8 delivered a staggering 493 horsepower and 516 lb-ft of torque, reducing the 0-60 mph sprint to just 4.5 seconds. Beyond the engine boost, the SL55 AMG featured larger wheels and brakes, a performance-tuned suspension, a quicker “SpeedShift” automatic transmission, a dual exhaust system, sport seats, and unique instrumentation, all contributing to a more dynamic driving experience.
Safety and Technology in the 2003 SL 500
Mercedes-Benz prioritized safety in the 2003 SL series, equipping it with a suite of active and passive safety technologies. Notable features included a range of acronym-based systems: ABS (anti-lock braking system), ASR (traction control), ESP (electronic stability program), and ABC (Active Body Control), all working in concert to enhance handling and safety. The 2003 SL was also the first vehicle to incorporate electronic braking, replacing the traditional mechanical linkage with an electronic system for faster response and individual wheel braking modulation during cornering. In the event of a collision, occupant protection was provided by multiple airbags, including head and torso side airbags and a driver’s knee airbag. Continuing a safety feature from previous generations, the 2003 SL included an automatic pop-up roll bar that deploys if a rollover is detected.
Interior and Special Features of the 2003 SL 500
A standout feature of the 2003 SL 500 is its power-operated retractable hardtop, similar to the one found on the Mercedes-Benz SLK. This standard feature replaced the traditional soft top, offering the security, insulation, and coupe-like aesthetics of a hardtop when raised. The interior featured a redesigned climate control system with user-friendly knobs and dials, a departure from the more complex button-heavy system in previous models. Customers had a wide selection of exterior colors and interior trim options, including various wood and metallic accents to personalize the cabin.
