Mercedes-Benz SLC (R172 facelift 2016) SLC 200 (184 Hp) 9G-TRONIC
The Mercedes-Benz SLC (R172 facelift 2016) SLC 200 (184 Hp) 9G-TRONIC represents a significant refresh and rebranding of the popular SLK-Class roadster. Unveiled in 2016, this iteration marked a pivotal moment for Mercedes-Benz’s compact convertible, aligning its nomenclature with the brand’s updated naming strategy, where “C” indicated its close relation to the C-Class. The R172 generation, originally launched in 2011 as the SLK, received a comprehensive update that included revised styling, enhanced powertrains, and improved technology, aiming to keep it competitive in the premium two-seat roadster segment. The SLC 200, in particular, served as a compelling entry point into the lineup, offering a balance of performance, efficiency, and the quintessential Mercedes-Benz luxury experience. Produced from April 2016 to July 2020, this model was designed primarily for the European and Asian markets, where its blend of a compact footprint, sophisticated design, and a modern turbocharged engine resonated well with discerning buyers seeking an elegant daily driver with open-top capability.
Engine and Performance: The Heart of the Mercedes-Benz SLC (R172 facelift 2016)
At the core of the Mercedes-Benz SLC (R172 facelift 2016) SLC 200 (184 Hp) 9G-TRONIC lies a sophisticated M 274.920 inline-four gasoline engine. This 2.0-liter (1991 cm³) powerplant is a testament to modern engineering, featuring direct injection and a turbocharger with an intercooler, allowing it to produce an impressive 184 horsepower at 5500 rpm. What truly sets this engine apart is its robust torque delivery: 221.27 lb.-ft. (300 Nm) available across a broad rev range, from a low 1200 rpm up to 4000 rpm. This wide torque band ensures responsive acceleration and effortless cruising, whether navigating city streets or tackling winding country roads.
Power is channeled to the rear wheels via Mercedes-Benz’s highly acclaimed 9G-TRONIC automatic transmission. This nine-speed unit is renowned for its smooth shifts, optimizing both performance and fuel efficiency. The combination of the turbocharged engine and the advanced transmission allows the SLC 200 to achieve a respectable 0-60 mph sprint in an estimated 6.6 seconds (0-100 km/h in 6.9 seconds) and reach a top speed of 147.26 mph (237 km/h).
Despite its spirited performance, the SLC 200 also demonstrates commendable fuel economy. The combined fuel consumption is rated between 38.6 and 41.3 US mpg (6.1-5.7 l/100 km), with extra-urban figures reaching an impressive 45.2 to 50 US mpg (5.2-4.7 l/100 km). This efficiency is further underscored by its Euro 6 emission standard compliance, with CO2 emissions ranging from 133 to 143 g/km, reflecting Mercedes-Benz’s commitment to environmental responsibility even in its sportier offerings. The engine’s layout is front-longitudinal, contributing to the car’s balanced weight distribution and classic roadster dynamics.
Design and Features
The Mercedes-Benz SLC (R172 facelift 2016) retains the iconic coupe-cabriolet body type, a hallmark of the SLK/SLC lineage, offering the best of both worlds: the security and refinement of a coupe with the exhilarating freedom of a roadster. The transformation from coupe to open-top is achieved by its signature vario-roof, a retractable hardtop that can be operated at speeds up to 25 mph. This facelift brought subtle yet impactful design enhancements, including a redesigned front bumper, a diamond radiator grille (standard on most models, optional on others), and revised LED lighting signatures that lent the car a more modern and assertive presence.
The SLC 200 is a strict two-seater, emphasizing its role as a driver-focused, intimate sports car. Its compact dimensions – 162.72 inches (4133 mm) in length, 71.26 inches (1810 mm) in width (78.98 inches including mirrors), and 51.22 inches (1301 mm) in height – contribute to its agile handling and ease of maneuverability in urban environments. The 95.67-inch (2430 mm) wheelbase provides a stable platform, while the relatively low drag coefficient of 0.30 aids both performance and efficiency.
Inside, the cabin features a driver-centric layout, with high-quality materials and meticulous craftsmanship characteristic of Mercedes-Benz. While the SLC 200 typically came with more standard equipment in its European markets, features like electric power steering, independent multi-link suspension at both front and rear, and ventilated disc brakes upfront (discs at the rear) ensured a comfortable yet engaging driving experience. Safety was paramount, with Anti-lock Braking System (ABS) as a standard assisting system, providing crucial stability and control. The trunk space is practical for a roadster, offering between 7.95 cu. ft. (225 liters) with the roof down and 11.83 cu. ft. (335 liters) with the roof up, enough for weekend getaways. The standard tire size was 205/55 R16 on 16-inch wheel rims.

Legacy and Market Impact
The Mercedes-Benz SLC (R172 facelift 2016) SLC 200 (184 Hp) 9G-TRONIC carved out a respectable niche in the luxury compact roadster segment. Its primary markets were Europe and parts of Asia, where its blend of premium branding, sophisticated design, and efficient yet capable powertrain proved highly attractive. While the SLC line, including more powerful variants, was available in the USA, the SLC 200 with 184 horsepower was typically positioned as an entry-level model more attuned to European tax structures and driving preferences. In these regions, it competed fiercely with rivals such as the Audi TT Roadster, BMW Z4, and Porsche Boxster, each offering a unique take on the two-seat convertible formula.
The SLC’s legacy is marked by its successful transition from the SLK nameplate, maintaining its core identity as a stylish, comfortable, and engaging open-top cruiser. The R172 facelift solidified its position as a modern classic, offering a compelling package of technology, design, and driving dynamics. The SLC 200, in particular, was praised for its balance, providing ample performance for daily driving and touring without the higher running costs associated with its more potent AMG siblings. Its relatively compact size and excellent turning circle made it particularly adept for urban environments and scenic drives.
The SLC (R172 facelift) continued the SLK’s tradition of offering a hardtop convertible, a feature that many competitors had abandoned in favor of lighter soft tops. This provided superior refinement, security, and all-weather usability, making it a versatile choice for year-round enjoyment. The 9G-TRONIC transmission was a significant technological highlight, contributing to its refined character and impressive fuel efficiency for a luxury sports car. As Mercedes-Benz shifted its focus towards electrification and a streamlined model lineup, the SLC was eventually discontinued in 2020, making this facelifted R172 generation the final chapter in a long and successful lineage of compact Mercedes-Benz roadsters. Its impact lies in its ability to offer an accessible yet authentic luxury roadster experience, blending elegance, performance, and practicality in a distinctive package.
