What engine does the Mercedes-Benz SL use?
3 Answers
Taking the 2017 model as an example, the Mercedes-Benz SL is equipped with a 3.0-liter V6 twin-turbocharged engine. The vehicle dimensions are 4646mm in length, 1877mm in width, and 1304mm in height, with a wheelbase of 2585mm. The Mercedes-Benz SL is positioned as a mid-size sports car with a convertible body style. In terms of power, the Mercedes-Benz SL features a 3.0-liter V6 twin-turbocharged engine paired with a 9-speed automatic transmission, delivering a maximum power output of 270kW, 367PS, and a maximum torque of 500Nm. The drivetrain is rear-wheel drive, with a multi-link independent suspension at the front and a multi-link independent suspension at the rear.
I'm familiar with the engine evolution of the Mercedes-Benz SL. As a long-time automotive enthusiast, the SL started with an inline-six engine in the 1954 300SL – powerful yet simple. By the 1980s, it transitioned to V8s like the 5.0L M113, delivering smoother torque. In the early 2000s, the R230-generation SL introduced turbocharged V6 and V8 options: the V6 prioritized fuel efficiency for daily use, while AMG models like the SL55 packed supercharged V8 punch. Modern SLs (R232 since 2022) feature AMG's 4.0L V8 biturbo (~577hp), blending rapid acceleration with improved efficiency and hybrid tech. Throughout its history, the SL has balanced performance and efficiency – though cooling system maintenance remains crucial.
As someone who frequently works on cars, the Mercedes-Benz SL commonly comes with a V8 engine, which has several key maintenance points: Classic models like the 1990s SL500 with the M119 V8 often suffer from spark plug aging or fuel line clogging, leading to starting difficulties or power loss—I recommend checking every 5,000 km. Modern SLs have switched to turbocharged engines, such as the V8 twin-turbo series, which have lower maintenance costs but more complex computer systems, requiring regular fault code scans. Among older models, the straight-six engines from the 1960s and 1970s are actually more reliable. When buying a used SL, check the engine number and avoid cheap deals to prevent high-voltage wiring issues. Also, monitor the coolant temperature during highway driving to avoid exceeding limits.
