2018 Mercedes S-Class S560 Review – Video
Mercedes-Benz S 560 4MATIC (fuel consumption combined: 8.5 l/100 km; CO2 emissions combined: 195 g/km) and Mercedes-Maybach S 560 4MATIC (fuel consumption combined: 9.3 l/100 km; CO2 emissions combined: 209 g/km): The new V-8 comes to the starting line with 345 kW (469 hp) and 700 Nm. The new biturbo engine is among the most economical V-8 petrol engines in the world, and consumes about ten percent less fuel than the predecessor.
To lower the fuel consumption, four cylinders of the new V-8 are deactivated simultaneously under partial load with the help of the CAMTRONIC valve-lift adjustment system. This reduces gas-cycle losses and enhances the overall efficiency of the four firing cylinders by shifting the operating point towards higher loads. The turbochargers positioned in the V of the cylinder banks represent another special feature.
