The overview of BMW data buses is provided over 3 tables:

Main bus systems
Sub-buses (local data buses)
Other data lines

Some bus systems are used both as main bus systems and as sub-buses, e.g. the I-bus.These buses are listed twice in the table below:in the main bus systems and in the sub-buses.

The tables are arranged alphabetically.

- Main bus systems

Bus designation	Description	Function	Bus structure	Bit rate	Model series
Bit rate: Data transmission rate * More information in section ”Frequently asked questions” ** LWL: fibre optics Subject to change. Date: September 2007
Byteflight	Bus for the passive safety system	The byteflight transmits critical data for safety (airbag). The byteflight transmits synchronously and asynchronously. *	Star * LWL **	10 MBit/s	E60 E61 E63 E64 up to 09/2005 E65 E66
CAN *	Controller Area Network	The CAN was originally developed by Robert Bosch. CAN buses are used in many areas. *	Bus *	Either fast (high-speed) or slightly slower (low-speed) *	E38 E39 E52 E53
I-bus	Instrumentation bus	The I-bus connects the control units for information and communication. The I-bus is a BMW standard with a low bit rate.	Linear * Single wire	9.6 kBit/s	E38 E39 E53
K-bus	Body bus	The K-bus connects the control units for the body electronics. The K-bus is a BMW standard with a low bit rate.	Linear * Single wire	9.6 kBit/s	E38 E39 E46 E52 E53 E83 E85 E86: R50 R52 R53
K-CAN *	Body controller area network	CAN is a bus standard.At BMW there are 3 buses with this standard: F-CAN K-CAN PT-CAN	Linear * Two wire	100 kBit/s *	E46 E60 E61 E63 E64 E70 E81 E82 E83 E85 E86: E87 E90 E91 E92 E93 R55 R56
K-CAN P	Body controller area network periphery	K-CAN P and K-CAN S are the two CAN buses for the body electronics. For the E65 and E66, the K-CAN has been divided between 2 buses: K-CAN P and K-CAN S. For safety, systems in crash areas are on K-CAN P.	Linear * Two wire	100 kBit/s	E65 E66
K-CAN S	Body controller area network system	See above	Linear * Two wire	100 kBit/s	E65 E66
MOST	Media Oriented System Transport	The MOST bus transmits the data for communication and information in the vehicle	Ring * LWL **	22.5 MBit/s	E60 E61 E63 E64 E65 E66 E70 E81 E82 E87 E90 E91 E92 E93 R55 R56
P-bus	Periphery bus	The periphery bus connects the control units in the doors, sliding/tilting sunroof and driver's seat with the general module. The P-bus is a BMW standard (like the K-bus). *	Linear *	9.6 kBit/s	E38 E39 E53
PT-CAN	Powertrain controller area network	The PT-CAN networks the control units for the drive and suspension systems.	Linear * Two wire	500 kBit/s	E46 E60 E61 E63 E64 E65 E66 E70 E81 E82 E83 E85 E86: E87 E90 E91 E92 E93 R50 R52 R53 R55 R56
