5 Series E61 523i (N52) TOUR
In automatic mode, the shift points are automatically controlled according to characteristic curves and are
adapted to the driving situation.
The SMG is available as special equipment (option 206).
So as to be compatible with higher-torque engines, the SMG are designed with different power ratings. The SMGs
therefore differ, for example, in terms of more powerful clutch actuators.
The following SMGs are installed depending on the motorisation:
-
GS6S37BZ (designed for a maximum torque of 370 Nm)
[System overview ...]
-
GS6S53BZ (designed for a maximum torque of 600 Nm)
[System overview ...]
The SMGs are based on the 6-speed manual transmissions GS6-53BZ and GS6-37BZ.
The principal benefits of the SMG compared to a conventional manual transmission:
-
No clutch pedal as the clutch is operated automatically
-
Selection of 4 operating modes:
•
Manual mode
Sequential, manual gearshift via gear lever or gearshift paddles
•
Manual mode with Dynamic Driving Control (FDC) via SPORT button
Sporty driving style by power steering being adapted (only with Servotronic) and intervention in engine and
transmission control
•
Automatic mode = D ("Drive")
•
Automatic mode with Dynamic Driving Control (FDC) via SPORT button
Sporty driving style by power steering being adapted (only with Servotronic) and intervention in engine and
transmission control
-
Short and precise gearshifts, no incorrect gearshifts possible
(gear change in approx. 0.15 seconds)
-
Safety and comfort: because the gearshift paddles are on the steering wheel, you can keep your hands on the
steering wheel when you change gear.
Brief description of components
The SMG system comprises the following components:
-
Gear lever with mounting block and gear lever cover
The gear lever allow gears to be changed in sequence (sequentially) by brief pressing.
The gear lever has 6 positions:
•
3 engaging positions for neutral ("N"), reverse gear ("R") and manual mode ("
-" symbol between "N"
and "D").
•
3 one-touch positions for "+", "-", "D".
The gear lever lock (shift-lock) is also installed in the mounting block.
The illuminated gear lever position indicator is located in the gear lever cover. [more ...]
-
Steering wheel with 2 gearshift paddles
The steering wheel with 2 gearshift paddles allows manual gear changes without the driver having to take his
hands from the steering wheel. Pull one or both of the gearshift paddles to shift up a gear. Press one or both of
the gearshift paddles to shift down a gear.
The two gearshift paddles are identical in construction and are wired in parallel.
