      • It was the fastest production car of its day.
    • 1955-1963: W121 (190 SL)
      • Alongside the 300 SL was the 190 SL, a grand touring convertible which shared the 300 SL’s basic styling, engineering, detailing, and fully independent suspension, but with a less powerful four-cylinder engine.
  2. 1960s: The W113
    • 1963-1971: W113 (230 SL, 250 SL, and 280 SL)
      • Introduced at the 1963 Geneva Motor Show, the W113 was led by Paul Bracq and Béla Barényi.
      • It featured a distinctive, patented, slightly concave hardtop, which inspired the “Pagoda” nickname.
  3. 1970s to 1980s: The R107 and C107
    • 1971-1989: R107 and C107
      • The R107 took the chassis components of the midsize Mercedes-Benz W114 model and mated them initially to the M116 and M117 V8 engines used in the W108, W109, and W111 series.
      • The C107 was the coupé version, introduced in 1974, known as the “SLC”.
  4. 1980s to 2000s: The R129
    • 1989-2001: R129
      • The R129 was based on the shortened floorpan of the Mercedes-Benz W124 and featured many innovative details, including electronically controlled damping (Adaptive Damping System, ADS) and a hidden, automatically extending roll-over bar.
  5. 2000s to 2010s: The R230
    • 2001-2011: R230
      • The R230 underwent revisions in 2006 and 2008, and was superseded by the new SL-Class R231 in 2011.
  6. 2010s to Present: The R231
    • 2012-present: R231

Motor Layout

The 2023 Mercedes-AMG SL43 features a front-engine layout, which is typical for the SL series. With the engine positioned at the front, it allows for a balanced weight distribution, ensuring stability and improved handling.

The rear-wheel-drive configuration, combined with rear-axle steering, offers enhanced agility and precision, especially during cornering. Rear-axle steering is a technology where the rear wheels turn in the opposite direction to the front wheels at low speeds (up to around 100 km/h in this case) to improve maneuverability. At higher speeds, the rear wheels turn in the same direction as the front wheels, improving stability.

This combination of front-engine, rear-wheel drive, and rear-axle steering ensures that the Mercedes-AMG SL43 delivers a dynamic and responsive driving experience, living up to the performance standards expected from AMG vehicles


ELECTRIC EXHAUST TURBOCHARGER IMPROVES ENGINE RESPONSE The operating principle of the electric exhaust turbocharger is based on the same technology used by the Mercedes-AMG Petronas F1 Team. Directly on the turbocharger’s shaft—between the turbine wheel on the exhaust side and the compressor wheel on the fresh air side—a roughly four-centimeter narrow electric motor is integrated. Electronically controlled, this motor directly drives the turbocharger’s shaft, accelerating the compressor wheel before the exhaust flow conventionally takes over.

This significantly improves the engine’s response right from idle speed and across the entire rpm range. The combustion engine responds even more spontaneously to accelerator pedal commands, making the overall driving experience more dynamic. Additionally, the turbocharger’s electrification allows for higher torque at low rpm, further enhancing agility and optimizing acceleration from a standstill. Even when the driver releases the accelerator or brakes, the e-turbo technology maintains the boost pressure, ensuring a consistently direct response.

The turbocharger, powered by the 48-volt onboard electrical system, operates at speeds of up to 170,000 rpm, allowing a very high air throughput. The charger, electric motor, and power electronics are connected to the combustion engine’s cooling circuit to maintain an optimal temperature environment. Combined with the internally named M139, a two-liter inline-four engine, this innovative technology in the SL 43 delivers a rated output of 280 kW (381 hp) at 6,750 rpm. The maximum torque of 480 Nm is available between 3,250 rpm and 5,000 rpm. Depending on the situation, the system also guarantees a temporary boost of 10 kW (14 hp) from the belt-driven starter generator (RSG).

The second-generation RSG also acts as a mild hybrid in the 48-volt onboard electrical system, offering functions like coasting and recuperation for maximum efficiency in addition to the temporary power boost. The 48-volt technology also enhances comfort, as the transitions of the start-stop and coasting functions are almost imperceptible.


AMG SPEEDSHIFT MCT 9G Transmission with Wet Start-off Clutch and Rear-Wheel Drive The M 139 designated four-cylinder, which has been used transversely in Mercedes-AMG’s compact models without an electric exhaust turbocharger for some time, is longitudinally positioned in the SL 43. In the entry-level model of the SL series, which is always rear-wheel driven, it is combined for the first time with the AMG SPEEDSHIFT MCT 9G transmission (MCT = Multi-Clutch Transmission). A wet start-off clutch replaces the torque converter.

This clutch reduces weight and, due to its lower rotational inertia, optimizes the response to accelerator pedal commands, especially during sprints and load changes. The meticulously calibrated software ensures extremely short shift times and, when needed, rapid multiple downshifts. Additionally, the throttle blip function in the “Sport” and “Sport+” driving modes provides a particularly emotional shifting experience. The RACE START function is also applied, ensuring optimal acceleration from a standstill.

The performance figures are fitting for its class: When required, the SL 43 accelerates from a standstill to 100 km/h in just 4.9 seconds, with a top speed of 275 km/h. In addition to the offered performance, the entry-level model of the series also stands out with comparatively low consumption and emission values.


AMG ADVANCED COMPOSITE BRAKING: OPTIMIZED FOR PERFORMANCE The AMG’s cutting-edge composite braking system sets a new benchmark in deceleration, offering both precision and reliability. Its standout features include minimal braking distances and a highly responsive feel, ensuring durability even under rigorous conditions. For added convenience, the system integrates hill start assistance, wet-condition dry braking, and automatic pre-filling. When the vehicle is stationary with the ignition off, it defaults to the “P” parking mode, and the electric parking brake disengages seamlessly upon ignition.

The brake system’s design emphasizes lightness, enhancing both agility and steering precision. The fusion of cast steel brake discs and aluminum brake pots, connected by specialized pins, not only conserves space but also promotes superior brake cooling. A novel addition is the direction-specific perforation, which not only reduces weight and improves heat dissipation but also ensures quicker wet-condition response and efficient brake pad cleansing post-braking.


REVOLUTIONARY CHASSIS DESIGN WITH ADVANCED FRONT AXLE AND STATE-OF-THE-ART LIGHTWEIGHT TECHNIQUES Standard in the SL 43 is the cutting-edge AMG RIDE CONTROL suspension, boasting top-tier aluminum dampers and featherweight coil springs. A first for any Mercedes-AMG production model, the new SL introduces a front axle with a five-link design, all neatly tucked within the wheel. This setup enhances the vehicle’s movement dynamics. A similar 5-link spatial configuration is employed at the rear.

To trim down the unsprung weight, all the suspension components, from the links to the wheel hubs, in both the front and rear axles, are crafted from premium forged aluminum. This multilink approach ensures minimal flexibility in wheel movement.

The design offers impressive stability during cornering, ensuring drivers feel a close connection to the road, especially during high-speed maneuvers or when faced with external factors like side gusts or uneven road surfaces.

An innovation in the design is the ultralight coil springs. Through specialized heat treatments, their weight has been minimized without sacrificing their robustness. In a pioneering move, the base of the spring is adhered to the spring itself, preventing wear and tear from debris over time. This ensures the spring remains corrosion-free throughout its use, allowing for enhanced load-bearing at a reduced weight, saving approximately 0.2 kilograms for each spring.

Another weight-saving initiative is seen in the torsion stabilizers on both axles of the SL 43. Their design, with varying wall thickness, ensures weight reduction. The thickest part of the wall is strategically placed where maximum stress is anticipated, specifically near the rubber mounts.

For those seeking customization, the SL 43 offers the newest AMG adaptive damping system. This system, using real-time data from various sensors, adjusts the damping for each wheel in milliseconds. Drivers can tailor the suspension feel using the AMG DYNAMIC SELECT modes, transitioning from the high-energy “Sport+” to the relaxed “Comfort” mode. A dedicated button also allows for further fine-tuning, independent of the preset driving modes.
