If you watch the video demo of the ZF 8-speed transmission or read the pdf, it tells you that it can handle up to 1000Nm of input torque (over 700lb-ft).
The new 8 speed ZF transmission is a whole new design that has some significant benefits. Some basic specs (compared to it's predecessor 6speed transmission):
- 11% fuel savings
- no additional weight
- 8 speeds--improves acceleration
- 200ms shifts (improved from 350ms)
- brand new gear design with only 4 gear sets and only 5 shift elements (2 open per gear)
- handles more torque (up to 1000Nm/700lb-ft)
- same cost
I'd say it's a pretty big engineering success.
