The Mercedes-Benz R129 SL: A look at the 1998 facelift

The Mercedes-Benz R129 SL, introduced in 1989 as a successor to the R107, became one of the most iconic luxury roadsters of its time. Its production continued until 2002, when the R230 replaced it. Among the many updates the R129 received during its long production run, the 1998 facelift stands out as a pivotal moment, marking a transition between early and late models.

1998 was significant for several reasons, particularly as it introduced several aesthetic and performance enhancements to the SL range. These updates, aimed at modernizing the vehicle and keeping it competitive, reflected Mercedes-Benz’s commitment to refining its design and engineering. Comparing early models such as the SL500 with late models like the SL320 reveals the notable differences brought about by the facelift.

Key exterior changes

The most obvious changes to the R129 came in its exterior design. One of the prominent updates was the introduction of upgraded Xenon headlights, which not only improved visibility but gave the SL a more contemporary appearance. The redesigned front bumper and updated rear lights complemented these headlights, giving the car a more cohesive and sleek look.

Another noticeable addition was the body-color bumper strip, which ran around the car, giving it a more modern and unified appearance. This seemingly simple change significantly refreshed the roadster’s design, helping it remain relevant as it entered the late 1990s.

When viewed from the side, the enlarged vent behind the front wheel stands out, particularly in comparison to earlier models. This larger vent added a more aggressive touch to the SL’s profile. Furthermore, the early SL models featured orange front and side indicators, a feature that has become increasingly rare. Other exterior updates included body-colored door handles and new alloy wheels, which added to the car’s contemporary appeal. The front and rear bumpers were also subtly reshaped to provide a more streamlined profile.

Interior and technological advancements

While the exterior changes were certainly eye-catching, the 1998 facelift also brought significant interior updates. One of the most subtle yet impactful changes was the upgrade of the odometer from mechanical to electronic in 1994, but in 1998, a chrome ring was added around the gauges. This small detail elevated the appearance of the dashboard, giving it a more premium feel.

The seats were also restyled during the facelift, with perforated leather replaced by soft Nappa leather, providing a more luxurious and comfortable experience. The cut of the seats was slightly altered, contributing to a more ergonomic design. A new steering wheel was introduced, smaller and more refined, enhancing the driving experience. The air conditioning and climate control system also received updates, with variations depending on the chosen options.

Engine and performance enhancements

The 1998 facelift also brought significant changes under the hood. The M119 V8 engine, which had powered earlier SL500 models, was replaced by the M113 V8, marking an important shift in engine technology. This new engine was more efficient and provided improved performance, aligning with the evolving standards of luxury and performance vehicles at the time.

In terms of technological innovations, one of the most notable additions was the “Tip-start” feature. This allowed the driver to turn the key once, after which the engine would crank on its own until it started, simplifying the ignition process. The 17-inch wheels became standard, contributing to improved handling and road stability.

Another significant change was the replacement of the oil pressure gauge with an oil temperature gauge, a subtle yet important update for monitoring engine performance. The engine vanity cover was also restyled, contributing to the car’s clean and polished under-hood appearance.

Practical updates

The 1998 facelift also introduced practical modifications. The automatic lock on the left rear storage compartment, which housed the Bose subwoofer, was removed. This small change allowed easier access to the compartment, improving convenience. Additionally, a storage net was added to the passenger side of the transmission tunnel, offering more storage options for drivers and passengers.
