Transmission and power transfer: tailor-made solutions
To match the wide engine speed range of the AMG 6.3-litre V8 engine, the
S 63 AMG teams up with the AMG SPEEDSHIFT 7G-TRONIC, while the high-
torque S 65 AMG is paired with the AMG SPEEDSHIFT 5-speed automatic
transmission. The driver can nudge the DIRECT SELECT shift lever on the
steering column to select the transmission settings "P", "N", "R" and "D". In
typical AMG style, individual gears can be shifted using the AMG shift paddles
on the steering wheel, rather like in a Formula 1 car.
Three different drive modes are available in the two AMG saloons: these shift
modes - "C" (Comfort), "S" (Sport) and "M" (Manual) are selected using a switch in
the centre console and differ in terms of their gearshift characteristics and speed.
In the manual "M" mode the transmission reliably remains in the selected gear,
enabling the driver to ideally harness the immense pulling power. Automatic
downshift under full throttle or during kickdown is similarly prevented as is an
upshift when reaching the engine speed limit. This allows drivers with a particu-
larly sporty streak to make even better use of the high power at their disposal.
The AMG instrument cluster displays the currently engaged gear and recom-
mended upshifts in "M" mode.
In line with the exceptional 1000 Nm torque, the S 65 AMG comes with a system-
atically reinforced drivetrain. In the automatic transmission this includes pur-
pose-built clutch plates with a high-quality metallic coating and the modified shift
and torque converter logic. Redesigned drive shafts, larger hub carriers as well as
strengthened steel spring links supplement these measures.
