585 HP Mercedes SL63 AMG 4-Matic+ too speed 315 km/h 197 mph best in class luxury Roadster 🔥🔥🔥

In the top model SL 63 4MATIC+ (combined fuel consumption 12.7-11.8 l/100 km, combined CO2 emissions 288-268 g/km) the engine develops 430 kW (585 hp) and provides a maximum torque of 800 Nm over a wide rev range from 2500 to 4500 rpm. The roadster's top engine thus conveys effortless superiority in every rev range. The acceleration from 0 to 100 km/h in 3.6 seconds illustrates this, as does the top speed of 315 km/h.

For use in the SL, the internally named M 177 engine received a new oil pan, repositioned intercoolers and active crankcase ventilation. The intake and exhaust ducts have been optimised for even more effective gas exchange and the exhaust gas routing for the catalytic converter box and petrol particulate filter has been enlarged. The developers achieved the increased output of the SL 63 4MATIC+ primarily through higher boost pressure and greater air flow, as well as modified engine software. To sum up, the eight-cylinder engine thrills with its exceptional power delivery and powerful acceleration in all engine speed ranges combined with maximum efficiency for low consumption and emission values.

In the SL 63 4MATIC+, the eight-cylinder engine features active engine mounts. The SL 55 4MATIC+ can be optionally equipped with this as part of the AMG DYNAMIC PLUS Package. The mounts solve the conflicting goals of achieving as soft a connection as possible to the powertrain for high comfort and as rigid a connection as possible for optimum driving dynamics, by steplessly and quickly adapting their rigidity to the respective driving conditions. These are liquid-filled rubber mounts. The vehicle sensors detect the respective driving situation as well as the resulting vibration behaviour of the engine and pass this information on to a control unit. It regulates the force with which the engine is coupled to the body and thus optimises the handling. For this purpose, a magnetic damper fluid is pressed through an annular gap of a coil in the mount. Differently high currents generate a magnetic force that regulates the flow and thus the engine mounts according to the information from the control unit.
