This from a Euro release Full release here
------
New features, MY2008 X5 (Europe):
* various EfficientDynamics standard features for all models (3.0d, 3.0si, 3.0sd, 4.8i) - reducing fuel consumption & CO2 emissions
* additional 3.0sd model with 3.0L I6 VTT engine (286HP; 580Nm)
* standard crash-active anti-whiplash headrests
* optional TV function for On-Board entertainment system
* standard DSC with SCI function* - for even more dynamic curving (better traction, less understeer)
* *Selective Control Intervention*
The xDrive four-wheel drive system, DSC electronic control system and engine control through integrated chassis management are combined for fast distribution of the drive torque in the longitudinal direction.
Meanwhile, further development of Dynamic Stability Control (DSC) has seen the introduction of Selective Control Intervention. During tight cornering it actively counteracts the tendency to understeer. This control intervention, which is also active when DSC is switched off, will initially be introduced from March 2007 in the four-wheel drive models of the new BMW 5-Series. Other models and model series from the BMW brand will follow.
If a vehicle tends to understeer when cornering, the current DSC system increases the braking pressure on the nearside rear wheel in order to generate a stabilising yaw moment. That action remains identical on the new system, but now engine torque can now increased independently of the position of the accelerator. This can generate an additional stabilising torque of up to 500Nm.
The torque compensation when the engine is running at partial load contributes to increasing the precision of the steering manoeuvres, tracking stability and traction when cornering. This is because the system enables the car to respond faster to the course determined by the driver, and steering corrections are less frequently required. The vehicle follows the path of the curve at constant speed despite the stabilising braking intervention.
