6 Series M6 (S85) Coupe
driving situation.
The 3rd generation of the sequential M transmission is a fundamentally new development.
Gear changes with this sequential M transmission are approx. 20 percent faster than with the 2nd generation. (In
the ideal case, a gear change takes only approximately 65 milliseconds.)
The fast gear change is made possible by the installation of 4 shift rods:
-
Shift rod R/1 (for reverse gear and the 1st gear)
-
Shift rod 5/3 (for 5th and 3rd gears)
-
Shift rod 6/7 (for 6th and 7th gears)
-
Shift rod 2/4 (for 2nd and 4th gears)
Each shift rod is hydraulically selected by a shift cylinder. The shift cylinders are actuated by the SMG control unit.
[System overview ...]
The sequential M transmission is designed for torque up to 550 Newton metres and engine speeds up to 8500 rpm.
The key benefits of the sequential M transmission compared to conventional manual transmissions:
-
No clutch pedal as the clutch is operated automatically.
-
2 operating modes can be selected:
•
Sequential mode (manual mode) "S":
Sequential, manual gearshift via gear lever or gearshift paddles
•
Automatic mode "D" ("Drive"):
Fully automated gear change
-
"Drivelogic" makes a total of 11 driving programs available, which are used to adapt the shift characteristics of
the sequential M transmission to the desired driving style.
-
Short and precise gearshifts, faults are not possible when changing gear
-
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.
Launch date:
09/2004.
Brief description of components
The "sequential M transmission" system consists of the following components:
-
Gear lever with gear lever cover
The gear lever allow gears to be changed by briefly pressing.
The gear lever has 6 gear lever positions:
•
3 engaging gear lever positions for neutral ("N"), reverse gear ("R") and manual mode ("
o" symbol
between "N" and "
D
/
S
")
•
3 one-touch positions for "+", "-", "
D
/
S
"
Gear indicator lighting is in the gear lever knob.
The following buttons are located in the gear lever cover: POWER, DSC, EDC and "Drivelogic".

Steering wheel with 2 gearshift paddles
2 gearshift paddles are on the steering wheel.
Briefly pull the right gearshift paddle to shift up.
Briefly pull the left gearshift paddle to shift down.
