The Mercedes-Benz SLK has a lineage that stretches back almost as far as the iconic Mercedes SL. In 1954, the precursor to the SLK, the 190SL, debuted, mirroring the SLK’s concept of leveraging smaller sedan underpinnings rather than sharing much with its high-performance sibling, the 300SL “Gullwing.” Just like the SLK today, the 190SL became a sales success, particularly along coastlines, appealing to affluent individuals seeking a refined and stylish convertible for pleasant weather drives.
The original 190SL produced 104 horsepower from its 1.9-liter four-cylinder engine. While it prioritized aesthetics over outright speed, it garnered popularity among a discerning clientele. The modern SLK 250, with its 1.8-liter, 201-horsepower engine, is a direct descendant of this philosophy. Recently, while in Palm Beach, I decided to rent an SLK 250 to evaluate if it maintained its position as a touring-focused roadster within the sport/touring spectrum. Having driven previous SLK generations, including a track experience at the Nurburgring in an SLK200, this was my first encounter with the current model, offering a chance to assess its contemporary interpretation of the SLK formula.
The as-tested price of the SLK 250 I drove reached $50,195, a step up from the base MSRP of $44,875. This increase was due to desirable options such as the seven-speed automatic transmission, upgraded 18-inch wheels, and the Premium Package, which included heated seats, a Harman/Kardon sound system, and additional cold-weather features. One could view this price point as substantial for a four-cylinder car, placing it between more powerful convertibles like the Ford Mustang GT and the higher-performing Chevrolet Corvette convertible. However, this perspective overlooks the SLK’s intended purpose. In locations like Palm Beach, owning a Mercedes-Benz often represents a baseline expectation within certain social circles. In a market where well-equipped family sedans can approach luxury car prices, the SLK 250 presents a relatively accessible entry point to Mercedes-Benz ownership, granting a certain level of social recognition.
However, the interior of the SLK 250, while functional, doesn’t necessarily scream luxury for the price. While it features brushed-aluminum trim, the standard MB-Tex upholstery might not impress passengers accustomed to higher-end appointments, unless opting for pricier designo leather upgrades. On a positive note, the cabin offers surprisingly generous space between the doors, a noticeable improvement over previous SLK generations. While additional legroom would be welcome, the standard “Panorama” smoked-glass roof provides ample headroom, even for taller occupants.
As a vehicle designed for navigating between upscale destinations, the Mercedes-Benz SLK 250 performs admirably. The retractable hardtop operates smoothly, opening or closing in approximately thirty seconds, providing both open-air enjoyment and a secure, insulated cabin when needed. With the top down, trunk space is reduced, but still offers enough room for a standard rollaway suitcase, suitable for weekend getaways. The climate control system is effective, capable of managing temperatures even in warmer climates, and the optional Harman/Kardon “Logic 7” sound system is a worthwhile upgrade, delivering clear and powerful audio even with the top lowered at highway speeds. Cruising with the top down and enjoying music enhances the overall driving experience.
The SLK 250’s 1.8-liter turbocharged engine, when paired with the standard six-speed manual transmission, likely provides adequate power. However, the test car was equipped with the optional seven-speed torque-converter automatic transmission. With this automatic, assertive throttle input is necessary to maintain pace with traffic, suggesting the engine might be considered just sufficient rather than genuinely sporty.
In standard driving mode, the automatic transmission starts in second gear, a characteristic Mercedes-Benz trait. Initial acceleration can feel somewhat leisurely, but once underway, gear changes are rapid. The 2-3 upshift even produces a sporty ignition cut-and-pop sound, reminiscent of performance cars like the Volkswagen GTI. While paddle shifters are available for manual gear selection, a noticeable delay between paddle input and gear change diminishes the engagement of manual shifting. The transmission’s programming prioritizes fuel efficiency, upshifting to seventh gear at relatively low speeds, resulting in the engine cruising at around 900rpm at 30 mph.
Despite the smaller engine and fuel-economy-focused transmission, the SLK 250 doesn’t achieve exceptional fuel efficiency. Rental car usage may contribute to this, but even with conscious efforts to drive economically, the observed fuel consumption was only 23.6mpg over a 100-mile drive. Comparatively, a Porsche Boxster with a larger 3.2-liter engine achieves better fuel economy, suggesting the SLK 250’s efficiency could be improved. This, combined with the diesel-like rattle from the direct-injected four-cylinder engine at idle, strengthens the argument for considering the more powerful 3.5-liter V-6 SLK 350 model, despite its higher price. The V6 would offer significantly enhanced power and refinement.
Years prior, the author tested a European-market SLK200 with a 163-horsepower engine and automatic transmission at the Nurburgring, achieving a lap time of 9:19. That previous generation SLK struck a favorable balance between handling and ride comfort, arguably more broadly appealing than contemporaries like the Porsche Boxster or BMW Z4 in terms of usability for most drivers. However, the current SLK 250 leans further towards comfort, possibly at the expense of outright driving engagement. The steering lacks feedback and feel, offering a weighted sensation that might be perceived as sporty by drivers of larger vehicles, but doesn’t inspire spirited driving on twisty roads. The chassis and stiff body effectively absorb bumps and potholes, suggesting potential for a slightly firmer suspension setup and improved steering connection. As it stands, the SLK 250 is not ideally suited for track days. It prioritizes comfort in line with the larger Mercedes SL, feeling both physically bigger and less agile than previous SLK models.
It’s tempting to criticize the SLK 250, especially considering Mercedes-Benz’s proven capability in building exceptional sports cars, exemplified by models like the SLS Black Series. Mercedes-Benz clearly possesses the engineering expertise to create a more emotionally engaging SLK. However, the current SLK 250 appears intentionally designed as a modern homage to the original 190SL. It delivers on style, comfort, and brand prestige, ensuring prominent parking at upscale venues. Its shortcomings in outright speed, track capability, and thrilling driving dynamics are likely inconsequential to its target demographic – buyers who prioritize style and comfort over ultimate performance. While driving enthusiasts might find a Porsche Boxster more rewarding, for those seeking the essence of the original 190SL – a stylish, comfortable, and prestigious roadster – the Mercedes-Benz SLK 250 remains a compelling option.
