- Chain track, single-part timing chain drive B58TU engine
- 6-cylinder engine
- Upper timing chain
- Timing chain
- Lower timing chain

The way the combined oil vacuum pump is driven via a separate drive chain
from the crankshaft has
not changed compared with the Bx8 engines. Only the change of the chain tracks
has changed:
The drive chain of the oil vacuum pump is now in front of the timing chain.

- Improved acoustics
- Lower space requirement
- Reduced weight

a height of 12.5 mm instead of a sealing ring. The spring force of the chain
tensioner lies between
40 Nm (extended) and 90 Nm (retracted).
