The six-cylinder in-line engine is characterised by top-of-the-range performance and intelligent electrification. The EQ Boost starter-alternator combines a starter motor and alternator in a powerful electric motor and is fitted between the engine and transmission. This innovation as well as the intelligent charging via an electric auxiliary compressor and an exhaust gas turbocharger all have the same goal: to enhance the hallmark AMG performance and driving dynamics, while at the same time reducing fuel consumption and emissions. And this move has been a successful one: the CLS53 4MATIC+ accelerates from zero to 100 km/h in just 4.5 seconds, and with the Driver's package achieves a top speed of 270 km/h. The combined fuel consumption is 8.4 l/100 km, and the combined CO2 emissions 200 g/km. (see table detailing technical data for figures for E-Class 53-series models).
