The Challenge
The Mercedes-AMG S 63 E PERFORMANCE, with a combined
output of 590 kW and a torque of 1,430 Nm, is the German
manufacturer’s most powerful S-Class model yet. The sedan
version is a globally approved high-performance plug-in hybrid
electric vehicle (HP-PHEV) from Mercedes-AMG with a P3
architecture. This means that the AMG 4.0-liter V8 biturbo
engine is supported by a permanently excited electric motor
located on the rear axle.
During development of the vehicle, electrifying the powertrain
with P3 architecture was a complex technical challenge.
Especially as the AMG S-Class model must meet the highest
standards in terms oJ sTortiness, comJort, and eƾciency.
Development and validation had tight deadlines and very
few physical prototypes. Further challenges of the project
included the simultaneous global market release (Western
Europe, China, Japan, the USA, and the rest of the world) and
meeting the respective emission standards, for example,
the European RDE legislation (Real Driving Emissions), the
emission standard China 6b, and the US guidelines for ultra-
low-emissions vehicles (ULEV 50 ready).
