2018 Mercedes-Benz S 450 (combined fuel consumption: 6.6 l/100 km; combined CO2 emissions: 150 g/km) and S 500 (combined fuel consumption: 6.6 l/100 km; combined CO2 emissions: 150 g/km): The new, systematically electrified in-line six-cylinder comes to the starting line in two output levels.
The S 450 (also as a 4MATIC model) develops 270 kW (367 hp) and 500 Nm of torque. The S 500 has an output of 320 kW (435 hp) and delivers 520 Nm. New, intelligent forced induction that includes an electric booster compressor as well as an Integrated Starter Generator (ISG) provide outstanding power delivery without turbo lag.
Over a short period, the beltless starter generator makes a further 250 Nm of torque and 16 kW of output available. Compared with the similarly powerful S 500 predecessor model with V8 engine, it has been possible to reduce the CO2 emissions of the engine by around 22 percent.
The significant power increase of the six-cylinder petrol engines to the level of the previous eight-cylinder units is also reflected in the model designations: The models with the new six-cylinder engines now therefore bear the designation S 450 or S 500.
Mercedes-Benz S 560 4MATIC (combined fuel consumption: 8.5 l/100 km; combined CO2 emissions: 195 g/km) and Mercedes-Maybach S 560 4MATIC (combined fuel consumption: 9.3 l/100 km; combined CO2 emissions: 209 g/km): The new V8 comes to the starting line with 345 kW (469 hp) and 700 Nm.
The biturbo engine is among the most economical V8 petrol engines in the world, and consumes about ten percent less fuel than the eight-cylinder predecessor model.
To lower the fuel consumption, four cylinders of the new V8 are deactivated simultaneously under partial load with the help of the CAMTRONIC valve-lift adjustment system. This reduces the pumping losses while improving the overall efficiency of the remaining four cylinders by shifting the operating point towards higher loads. The turbochargers positioned in the V of the cylinder banks represent another special feature.
Mercedes-Benz S 600 (combined fuel consumption: 11.6 l/100 km; combined CO2 emissions: 270 g/km: The top-of-the-line Mercedes-Benz is the V12 with 390 kW (530 hp) and 830 Nm. The new twelve-cylinder engine in the Mercedes-Maybach S 650 delivers 463 kW (630 hp) and a maximum torque of 1000 Nm (combined fuel consumption: 12.7 l/100 km; combined CO2 emissions: 289 g/km).
Mercedes-AMG S 63 4MATIC+ (combined fuel consumption: 8.9 l/100 km; combined CO2 emissions: 203 g/km): For superior performance with significantly reduced fuel consumption, the AMG 4.0-litre V8 biturbo engine with cylinder deactivation replaces the previous 5.5-litre V8 biturbo. Despite a lower displacement, the new engine generates 450 kW (612 hp). The Mercedes-AMG S 65 is equipped with a twelve-cylinder engine developing 463 kW (630 hp) and 1000 Nm (combined fuel consumption: 11.9 l/100 km; combined CO2 emissions: 279 g/km).
