- Anti-theft alarm system
The anti-theft alarm system (DWA) detects and reports attempts at intrusion and tampering with the vehicle. The vehicle interior is monitored by an ultrasonic interior protection system (UltraschallInnenraumschutz, USIS). If an attempt is made to gain access to the vehicle interior, an acoustic alarm is triggered from an emergency power siren and a visual alarm via the lighting system (hazard warning lights). A tilt alarm sensor is tripped if the vehicle is raised or taken in tow. The tilt alarm sensor responds by triggering the anti-theft alarm.

- Passive safety system
At this time, BMW is the only carmaker to offer the "Advanced Safety Electronics" (ASE) passive safety system. ASE is based on the byteflight high-speed, optical data bus. Individual sensors permit optimum control of the pyrotechnical components of the restraint system (e.g. airbags, belt tensioners and active head restraints). The safety and gateway module (SGM) has the role of superordinate control unit and intelligent star coupler. Moreover, the SGM also make available an energy reserve for the entire safety system in the event of the power failing in an accident. If the accident severity is above a certain threshold the electric fuel pump is switched off. The safety battery terminal (SBK) separates the starter motor and the alternator from the battery's positive post. The onboard power supply is connected to the battery. This means that all emergency functions are retained In the event of a crash.

- iDrive, central information display and controller
The E65 saw the debut of iDrive. It marked the assumption by BMW of leadership in the development of new operator communication systems. Evolution of the iDrive system was continued for the E60 and E61. Ergonomics have been further optimized to accommodate the increasing number of functions available in the car. The position on the Central Information Display (CID) and the controller and the logic of the system make iDrive the leading operator communication system. The menu structure has been further developed and simplified. The start menu is now subdivided into four color-coded sections, "Communication", "Navigation", "Entertainment" and "Air-conditioning".
The CID is available in 2 different sizes (6.5 and 8.8 inch), depending on equipment specification.
iDrive has been given an additional menu button. The single-piece menu button from the multi-audio system controller
(M-ASK) allows a quick return to the start menu. On the Car Communication Computer (CCC), there is an additional second button for the voice recognition system.

- Head-up display
The Head-Up Display (HUD) projects a "virtual" image in front of the windscreen. The image is projected approximately 2.20 m ahead of the windscreen. The image is visible only from the driver's side. This driver-relevant information contained in this "virtual" image depends on the vehicle equipment, and can include, for example:
- Car road speed
- Cruise control (FGR) or Active Cruise Control (ACC)
- Navigation instructions
- Check-Control messages

- Instrument cluster
The round instruments of the instrument cluster in the E60 and the E61 have 2 moving-segment indicators. The moving-segment indicator on the left is around the speedometer. The left moving-segment indicator shows the speed setting (= selected speed in mph for the cruise-control system). The moving-segment indicator on the right is around the revolution counter. The right moving-segment indicator shows the engine-overspeed warning field (engine speed limits vary, depending on engine temperature). Between the two round instruments there are an LCD display and a number of indicator and warning lights.
The brightness of the liquid-crystal display adjusts to suit ambient brightness. At temperatures under 10° Celsius the liquid-crystal display is heated, in order to ensure good legibility right from the beginning.
The fuel-consumption gauge is in the round instrument on the right (revolution counter).

- Adaptive headlights
Adaptive Head Light (AHL), option code 524, is available only in combination with option code 522 "Xenon lights".
As the car corners, AHL pivots the low-beam headlights and the high-beam headlight slightly toward the inside of the corner (in other words, to the right if the car is cornering to the right). The curve is then illuminated better and visibility is improved. If the vehicle drifts, skids or loses sideways grip, the adaptive headlights function is deactivated. The headlights are then returned to the straight-ahead position.

- Integrated automatic heating and air-conditioning system
This is the first time that an integrated automatic heating and air-conditioning system (IHKA) has been available as standard in cars in this class. The IHKA is available as a basic version and as a high version (as option code 534). The IHKA High has separate controls for the driver's side and passenger side, in order to enhance the comfort of the car's occupants.
The main new features of the IHKA are:
- Electric auxiliary heater for vehicles with diesel engine
Electric heating elements made of aluminium have been added to the plates in the coolant flow of the heating system heat exchanger. The inducted air is heated directly by these heating elements, before the engine reaches its operating temperature.
- Condensation sensor
The condensation sensor is active only in the IHKA's automatic program. The condensation sensor monitors for conditions under which condensation fogs the windows. The condensation sensor measures the moisture content of the air at the front windscreen. If a value higher than 65% is measured, the IHKA control unit starts the program to prevent fogging of the windows.
- LIN bus (Local Interconnect Network bus)
The IHKA control unit controls the electric auxiliary heater, the flap motors and the blower via the LIN bus.

- Park Distance Control
The Park Distance Control (PDC) system from the E65 has been adapted for the E60 and the E61.
New for the PDC in the E60 and E61: The signal from the PDC button is transferred through the K-CAN to the PDC control unit. The signal from the reverse-light switch (reverse gear engaged) on vehicles with manual transmission is transferred from the light module to the PDC control unit via the K-CAN. As in the E65, the visual alarm is also shown in the Central Information Display (CID).

- Information and communication systems
The Multi audio-system controller (M-ASK) is installed as standard in the E60 and E61. The following systems are controlled by the M-ASK:
- Audio functions
- Central Information Display (CID, 6.5 inch)
- Navigation system (option code 606)

In the "High" version, this control function is assumed by the Car Communication Computer (CCC). The CCC controls the audio functions and the Central Information Display (CID, 8.8" in the High version). The voice recognition system and option code 609 "DVD navigation system Professional" are also controlled by the CCC.
- Audio functions
- Central Information Display (CID, High version with 8.8" display)
- Voice recognition system
- DVD navigation system Professional (option code 609)
[more in SI Technical (SBT) 84 06 03 053] Car Communication Computer
The M-ASK and the CCC are programmed through the MOST direct access.
The navigation system receives its map data from the navigation DVD.

- Condition Based Service
Condition Based Service (CBS), as the name suggests, is a means of ensuring that the car is serviced as and when necessary. CBS has been in use by BMW Service since the launch of the E65. CBS is a landmark in the increasingly close communication and networking between vehicles and Service. The vehicle's specific service needs are registered manually or by TeleService. TeleService can issue an automatic service call, notifying the home dealership when service is due. The instrument cluster indicates whether a service is due. When terminal 15 is switched ON, the "Next Service" indicator appears in the LCD display (remaining visible for 6 seconds). More information on CBS can be called up at the same time on the central information display (CID). There are currently nine defined service scopes:
- Engine oil
- Micro filter
- Brakes front
- Brakes rear
- Brake fluid
- Vehicle check
- Spark plugs (DME only)
- Roadworthiness test
- Exhaust emissions test

The service interval can be reset by means of the reset button in the instrument cluster (press and hold down for longer than 5 seconds). The scheduled times for the roadworthiness test and the exhaust-emissions test can be entered through the Controller or the Central Information Display.

Suspension






- Aluminium suspension
Intelligent lightweight construction was a definitive aspect of the design brief for the E60 and E61. The innovative aluminium chassis and running gear factor into weight reduction, as does the lightweight aluminium front end (GRAV). The control arms and transverse links are made of aluminium and ensure high-precision tracking of the wheels. The highly innovative design principle with the special layout of the leading links and control arms ensures high-precision steering. The low axle loads, especially in the area of the front axle, also provide for a high degree of agility and for the familiar BMW handling characteristics. Aluminium wheels and generously dimensioned aluminium brake calipers round off the intelligent lightweight construction concept.

- Active front steering
Active Front Steering (AFS) comes complete with Servotronic in the E60 and E61. AFS varies the ratio of the steering gear from direct to indirect and vice versa as a function of the car's speed.
The benefits of Active Front Steering are:
- Direct steering with light steering effort at low speeds
- Indirect steering at high speeds with positive directional stability

At low speeds, Active Front Steering reduces the number of steering wheel tuns required to move the wheels from lock to lock: instead of three full turns as in the past, less than two complete turns suffice to move the wheels from full lock to full lock. Less effort is needed to turn the steering wheel when turning in urban traffic or maneuvering tight parking spots.
Active Front Steering damps rotary movement of the car about its vertical axis. AFS intervenes electronically and imperceptibly at all speeds. This means that Dynamic Stability Control (DSC) intervenes less frequently and its action is less noticeable.
Unlike steer-by-wire systems, Active Front Steering has a mechanical link between the steering wheel and the front wheels. The authentic "feel" of the steering is sustained even if the AFS system fails.

- Dynamic Stability Control
Dynamic Stability Control (DSC 8) is standard in the E60 and the E61. DSC 8 was evolved from the DSC system installed in the E65.
The key new features are:
- Very compact DSC unit, approximately 25% smaller and some 30% lighter
- No electric pre-pressurizing pump
- DSC unit connected to the chassis CAN (F-CAN) and the powertrain CAN (PT-CAN)
[more in SI Technical (SBT) 34 02 03 042] Dynamic Stability Control DSC 8

- Dynamic drive
The E60 and E61 are the first 5-Series cars from BMW to have Dynamic Drive (ARS = Active Roll Stabilization). The hydraulic Dynamic Drive system is a weight- and energy-optimized active control system for the chassis and running gear. Dynamic Drive prevents the car from yawing (= pivoting about the longitudinal axis when cornering).
In this way, Dynamic Drive increases directional stability. It is based on vertically split stabilizers on both axles. Each half of the anti-roll bars has a hydraulic pivot motor, which reacts within milliseconds to adjust the running gear to changing driving situations.

- Runflat indicator
The runflat indicator (RPA) belongs to the standard equipment on the new BMW 5-series. The runflat indicator is integrated in the DSC control unit.
By comparing the speed signals for all four wheels, the system detects differences in rolling circumference at the individual wheels.
A flat tire is indicated when a discrepancy is detected.
[more in SI Technical (SBT) 36 01 04 078] Run Flat Indicator All Models

- Tires with emergency-running characteristics (run-flat tires)
Tires with emergency-running characteristics can be fitted to the E60 and E61, in combination with the runflat indicator. These tires have reinforced sidewalls. This makes the tires self-supporting: even when deflated, the tire retains its strength and does not go flat. In the event of a puncture, therefore, the car can be driven to the next workshop, as follows: Maximum range of 150 kilometers at medium load and a speed of max. 80 km/h.

- Self-levelling suspension
The E61 from BMW offers a uniformly high level of ride comfort with self-levelling pneumatic rear suspension. The suspension is self-levelling, irrespective of the load carried in the car. Two height sensors, one at each rear wheel, detect the ride height of the car. The increased elasticity of the aluminium rear axle in the vehicle's longitudinal direction increases the load on the pneumatic springs. On account of this increased load, BMW is the first manufacturer to adopt pneumatic springs with two cushions. The second, topmost cushion acts as an extra articulation. It reduces the load on the pneumatic springs.

Drive train
- Engines
The engines available for the 5-Series BMW are the tried-and-tested models listed below:






- Transmission
The transmissions available for the E60 and E61 are as follows:
- 6-speed manual transmission
- 6-speed automatic transmission

- Sequential manual transmission
A sequential manual gearbox (SMG) is available for the E60 and the E61. The gears are shifted sequentially. The driver shifts gear by moving the gear lever in the center console or by means of the two paddles on the steering wheel.
