The Mercedes-Benz S550, a beacon of luxury and sophistication, already boasts impressive performance. However, for those seeking to elevate their driving experience beyond the factory settings of their 2015 model, RENNtech offers a meticulously engineered performance upgrade package. This enhancement, accessible via the OBD2 port, unleashes the true potential of your S550, blending seamlessly with its inherent elegance.
RENNtech, a renowned name in high-performance Mercedes-Benz tuning, has developed a comprehensive suite of upgrades specifically designed for the W222 S550 sedan. This package is not about brash modifications; it’s about refined enhancements that amplify both the performance and visual appeal of your vehicle.
RENNtech’s Sport Package: A Symphony of Performance and Style
This thoughtfully curated package includes several key components, each designed to work in harmony to deliver a transformative driving experience. The core elements of the RENNtech S550 Sport Package are:
- RENNtech ECU Upgrade: Optimizing engine performance through the OBD2 port for significant gains in horsepower and torque.
- RENNtech Carbon Fiber Decklid Spoiler: A subtle yet impactful aerodynamic enhancement crafted from lightweight pre-preg carbon fiber.
- RENNtech Stainless Steel Sport Mufflers with Electronic Actuated Valves: Providing a more aggressive exhaust note when desired, while maintaining refined sound levels for everyday driving.
For those looking to further personalize their S550, optional RENNtech Deep Monolite Wheels are also available, completing the visual transformation.
OBD2 ECU Tuning: Releasing the Beast Within
At the heart of this performance upgrade lies the RENNtech ECU tune. Modern vehicles like the 2015 Mercedes S550 utilize sophisticated engine control units (ECUs) that manage various aspects of engine performance. RENNtech’s expertise allows them to recalibrate these parameters via the OBD2 port, safely and effectively increasing power output.
This OBD2 tuning process unlocks the latent potential of the 4.7L V8 Biturbo engine, boosting figures to an impressive 540 horsepower and a staggering 705 lb-ft of torque. Beyond the peak numbers, the ECU tune also sharpens throttle response, making the S550 feel more agile and responsive in all driving situations. This transformation elevates the S550 from a comfortable luxury sedan to a vehicle with genuine AMG-esque performance capabilities, all achieved without compromising the car’s inherent smoothness and refinement.
A Refined Roar: Sport Mufflers and Electronic Valves
The RENNtech stainless steel sport mufflers add another layer of excitement to the driving experience. These mufflers are engineered to provide a deeper, more resonant exhaust note, enhancing the auditory feedback without becoming intrusive. Crucially, they incorporate electronic actuated valves that utilize the OEM actuators. This clever system allows the exhaust to remain relatively quiet during low RPM cruising, ensuring comfortable everyday driving. However, when you demand more, the valves open, unleashing a more aggressive and sporty sound that perfectly complements the increased performance. All RENNtech exhaust systems are designed and manufactured in-house at their facility in the USA, ensuring the highest standards of quality and fitment.
Carbon Fiber Elegance: The Decklid Spoiler
The visual enhancements are as subtle and sophisticated as the performance upgrades. The RENNtech carbon fiber decklid spoiler is a prime example. Crafted from pre-preg carbon fiber, this spoiler is not just about aesthetics; it also contributes to improved aerodynamics. The pre-preg carbon fiber construction ensures exceptional strength, lightness, and a flawless finish. This manufacturing process, commonly used in aerospace and military applications, results in a carbon fiber component of superior quality compared to traditional wet-layup methods. The spoiler adds a touch of sporty elegance to the rear of the S550, subtly hinting at the performance within.
Optional Deep Monolite Wheels: The Final Touch
For the ultimate personalization, RENNtech offers optional Deep Monolite wheels. These wheels are more than just a visual upgrade; they are engineered to enhance both aesthetics and performance. Available in 21″ front and 22″ rear fitments and in 10-, 10.2- and 16-spoke designs, they allow owners to tailor the look of their S550 to their exact preferences. The wheels are offered in brushed aluminum, gunmetal, or titanium finishes. Constructed from forged monoblock aluminum, these wheels are significantly lighter and stronger than cast wheels, contributing to improved handling and responsiveness.
Performance Data: Numbers That Speak for Themselves
The RENNtech Sport Package delivers tangible performance gains, transforming the S550’s already respectable numbers into truly impressive figures:
| Model | Upgrades | 0-60mph | 0-100mph | 1/4 Mile ET | 1/4 Mile MPH |
|---|---|---|---|---|---|
| 2016 – W222 S550 Sedan | Stock | 4.83 sec | 11.51 sec | 13.32 sec | 106.98 mph |
| Sport Package | 4.33 sec | 10.13 sec | 12.75 sec | 111.62 mph | |
| Sport Pkg + Transmission Software | 4.19 sec | 9.88 sec | 12.62 sec | 112.27 mph |
These numbers clearly illustrate the significant improvement in acceleration achieved with the RENNtech Sport Package. The enhanced S550 becomes noticeably quicker and more responsive, offering a more engaging and exhilarating driving experience.
Conclusion: The Perfect Blend of Luxury and Performance
RENNtech’s Sport Package for the 2015 Mercedes-Benz S550 masterfully bridges the gap between the standard model and the high-performance AMG variants. Through carefully selected and expertly engineered upgrades, accessible via OBD2 tuning for the ECU, RENNtech unlocks the hidden potential of the S550, creating a vehicle that is both luxurious and genuinely thrilling to drive.
