I have no idea which cars will get it.

I was told quite a while ago Dynamic xDrive was developed with X5/X6 in mind (so X6 is definitely getting it - I thought X5 would be the first model to feature it, yet I guess it wasn't ready till X5 launch - or BMW want to debut it in X6 since X6 is more sporty car than X5). Yet I'm sure other cars with xDrive will get it.

And I'm sure DPC will be also used in RWD cars as well - I guess in more sporty oriented ones (eg. coupes, roadsters & performance versions).

Perhaps DPC will be also featured in some specific 1er models in the future. Who knows ...

OK...thank you EnI. Helpful as always. I guess I'll have to learn to live without the DPC.

Still waitin' on the 1er to arrive in the showrooms here in Athens, GR.

I guess that system should be on 130i or perhaps even stronger 1er's.

This sounds sweet. I'm pretty sure that this will appear on 1er. Which one? I'm pretty sure on the new M1 or at least a 1er with M-package.

The X6 will be the first model to have this system

BMW has just taken the wraps off an advanced torque vectoring system that promises to improve both the agility and stability of its four-wheel drive models.
Called Dynamic Performance Control, the new system is an evolution of BMW’s xDrive system, but adds a series of additional electro-magnetic clutches, in a modified rear differential housing that allow power to be juggled between the individual rear wheels as well as between the front and rear axles.
Dynamic Performance Control works in conjunction with sensors in the anti-lock braking system that measure steering angle, yaw rates, road speed and torque developed by the engine. Essentially, it directs drive to where it can be used most effectively in an operation not dissimilar to that of a traditional locking differential on a rear-wheel-drive car.
If the car understeers, xDrive will redirect more drive to the rear wheels and, if required, the Dynamic Performance Control system will then load up the outside rear wheel with the balance of power, providing an additional turning moment beyond that generated by the steering wheels. During oversteer, it reverses the action, sending the majority of drive through the front wheels and, if necessary, increasing torque to the inside rear wheel to stabilise the car during cornering. Both processes are explained in BMW's images, which you'll find in our gallery.
Unlike similar systems developed by rival car makers, BMW’s Dynamic Performance Control operates both under load and on the overrun, meaning the car continues to be stabilised even when the driver steps off the throttle mid-corner. The new system adds 12kg to the weight of the car, but it is concentrated low down in the chassis so as not to affect handling to any great degree.

Coming to a BMW near you


BMW is tight-lipped on when Dynamic Performance Control, developed in partnership with German engineering specialist ZF, will be introduced. It will probably appear first on the X6 crossover coupe, before heading into other models, including the X3, X5 and four-wheel-drive versions of the 3-, 5- and next-generation 7-series. Also earmarked to accept the new system is BMW’s seven-seat MPV, and a secret new junior four-wheel-drive that’s tipped to slot into the German car maker’s line-up beneath the X3.

So what does it feel like?


In an exclusive test drive at BMW’s newly established winter test centre in Arjeplog, Sweden this week, Autocar was able to evaluate Dynamic Performance Control on a fleet of modified 530iX saloon and touring models.
It's a subtle but worthwhile improvement. By allowing the torque to be distributed in varying degrees to either the left- or right-hand rear wheels, the cars equipped with the new BMW system proved more neutral during cornering than those running the existing four-wheel drive xDrive mechanical package.
Understeer is well suppressed thanks to the ability of Dynamic Performance Control to direct greater torque to the outside rear wheel, and big oversteer moments are quickly dealt with as the inside rear wheel is favoured. The upshot is improved cornering balance, and an ability to delve deeper into the car’s dynamic repertoire, more of the time.
As well as instilling greater confidence in the driver, the new system also reduces the amount of steering input required, which was typically halved as we attacked BMW's winter handling course. For this reason, BMW does not plan to equip models running Dynamic Performance Control with its Active Steering system.

Sounds like this is the system that will pave the way towards AWD M cars.

Can't wait to see it on the X6 in combo with the the M V10/V8

[Just_me]

Automotive supplier ZF has created a new torque vectoring rear axle drive system that has been designed to distribute drive torque individually between a car’s rear wheels. This is said to improve agility and stabilize the vehicle, while also providing better handling in critical situations.

130607zf_vector.jpgWhen driving in a straight line, the torque vectoring rear axle acts like an ordinary transmission with an open differential, with drive being distributed equally among both sides of the drive-shaft. The torque is only distributed individually to either wheel during cornering, where it’s controlled by an electromechanically actuated multi-disk brake of the superimposed axle drive.

The new system is planned for volume application in future BMW vehicles and will be available for both AWD and RWD models. However, there’s no word on which new models the intelligent torque distribution system will debut in.

Wow, so this seems to be something that would eliminate the need for an LSD? This would also make accessing the handling limits of the cars much easier for the driver, and less of a pins and needles driving experience. Added benefit for driving in nasty weather as well.

Feel free to correct me if I have the wrong idea?

This is the unit behind BMW's DPC - Dynamic Performance Control system.

X6 will be the first AWD model with DPC (aka Dynamic xDrive), while F01/2 7er is rumored to be the first RWD model to come with DPC feature.

So in a way this makes driving a RWD car in poor weather conditions almost just as good as AWD? I like how DPC also lowers the DSC threshold and allows for a more natural driving experience free of electronic intervention. Excellent work BMW, excellent work.
