From a technical perspective, the transmission is many variants use zf 5/6-speed automatics (where fitted); manuals also exist. at this torque level, transmission and driveline servicing history becomes especially important..
Considerations: Turbo petrol: fuel quality and cooling can influence repeatable performance.. High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
