Engine: 4.0L V8 Biturbo with Maybach Refinement
The SL 680 is powered by the handcrafted 3,982 cc V8 biturbo engine. While it shares its core with the AMG SL 63, it is tuned specifically for the Maybach "Monogram Series" to deliver power more linearly and quietly. It produces 577 bhp (585 PS) and 800 Nm of torque. The engine mounts are softened, and the exhaust system is hushed to provide a more dignified acoustic profile.
Acceleration and Speed: 0-100 km/h in 4.1 seconds
The focus here is effortless momentum rather than violent launches. The SL 680 accelerates from 0-100 km/h in 4.1 seconds (slightly slower than the AMG due to added luxury insulation and weight). The top speed is electronically limited to 260 km/h (161 mph) to maintain structural and acoustic serenity.
