What's the difference between Electronic Damper Control and Performance Control
Just looking at the UK stats ...
I thought all cars have Performance Control (2VG), but actually only 43% of cars appear to. Electronic Damper Control, which I thought was called Variable Damper Control (223) as I understand it allows you to change between Normal and Sports Suspension. I am trying to understand if VDC has any dynamic or adaptive qualities compared to the non 223 option, and what effect that actually has on ride quality. Would you notice you have VDC if you never used the rocker switch to change to Sport or Sport+. I have read many of the posts on VDC and I still am not 100%! What's Performance Control? |

I think performance control comes with the dynamic handling package or the m sport package, but if you don't get either of those you don't get it. The performance control moves the power bias rearward so it feels more like a RWD vehicle. So basically nothing to do with ride quality.

Dynamic Damping Control is always in effect if you have that option. It is not the difference between Sport and Normal, it's the car constantly tweaking the damping coefficient to produce the ride selected -- Sport or Normal -- more effectively than a suspension without that ongoing tweaking. For example, the front wheel hits a pot hole, so the system anticipates by adjusting the setting of the rear wheel to accommodate the pot hole and produce a better ride (whether that's a firmer Sport ride or a more compliant Normal ride).
Dynamic Damping Control from BMW Press the Driving Experience Control button next to the gear select lever and change from COMFORT to SPORT, or even to SPORT+. The engine responds more spontaneously, the eight-speed automatic transmission Steptronic lets the rpm go higher before each fast and precise gear shift. The suspension becomes stiffer and sportier. Dynamic Damping Control uses data collected by sensors throughout the BMX X3: each second, it gathers thousands of readings about the position of the steering wheel, the strength of lateral forces, wheel rotation speeds and much more. The system calculates the best possible setting for each individual wheel and continually adjusts its suspension accordingly. The BMW X3 hugs the road through tight bends and still provides a comfortable, safe ride for all occupants. Dynamic Driving Control is an option available with Dynamic Damping Control, with eight-speed automatic transmission Steptronic, or with variable Sports steering.

Performance Control from BMW
In modern automobiles, the wheels on an axle are connected by a differential – a special gear that adjusts for this difference in length. BMW Performance Control takes this individual control a step further by changing engine output and if necessary applying braking force: the outer wheels get greater drive power, the inner less, and all four can engage with maximum traction. The BMW X3 literally drives into the curve, for an even greater sense of dynamic driving and excelling stability.

Not exactly torque vectoring...
The X3 system just uses brake to negate the torque on the inner real wheel.
The X6 system is more advanced, and it actually varies torque between the rear wheels. |

Torque vectoring also is a bogus term. The effect is the same between the two, the difference is the braking solution bleeds of more power than the one that alters the power delivered to the individual wheel. It's not a complete either/or here, though. This system modifies power delivered front/back, but individual wheel differentiation is done by braking. It still works well and is noticeably different than not having it.

Adaptive damping is, IMHO, one of the most impressive options you can have. It allows you to have a limo-like gliding along feel ( when the wife or kids are with you) or a firm sporty ride when you are on your own! It works with the computer to vary ride while the computer also (in sport) doesn't change up as soon, makes the engine more responsive to the throttle and alters the steering rates. But without adaptive damping, nothing can change the ride quality.
I' taking many liberties with accuracy here, but you can think of regular dampers as being like a doctors syringe full of oil. It takes effort to squirt out the oil because you have to force it out through a small hole. There is a spring around the syringe to push the plunger back out. On a car a one way valve allows the oil to be sucked back in very quickly ( through a large hole) as the spring pushes the wheel down/car up after being squashed. It stops whole car bouncing up and down on the springs multiple times (think simple harmonic motion in school physics class!) Adaptive damping electronically varies the size of the hole very fast based on information from the car's various sensors and your chosen setting. Sport will use smaller apertures and give a firm ride, normal gives bigger apertures and a softer ride. It's a neat system, quite inexpensive (for BMW) since its code plus more expensive dampers. Fully "active suspension" is much more expensive and complex - and more likely to fail as a result. Computer controlled hydraulic pumps at each wheel etc.

Reading the brochure and talking to the BMW sales staff, all X3s have Drive Performance Control, with Comfort & Sport Settings, but this only controls the engine response and does nothing for the suspension. The Variable Damping Control allows control over the shock absorbers for improved performance & smoother ride depending on the setting, and also adds a Sport+ mode.
Apparently.

VDC X3s have different shocks that change the viscosity of a liquid by using electric charge so the car can automatically make 1000s of quick adjustments to smooth out the road. They also mean you can change the default and make the suspension firmer (Sport). There is no Sport+ setting for the suspension. Sport+ is just Sport with DTC switched off

According to the brochure it says Drive Performance Control is a standard option and says: Drive Performance Control including ECO PRO mode, enables you to switch between the Comfort, Sport and Sport+ modes at the touch of a button. Sport+ mode only available in conjunction with the Sport automatic transmission or Variable Damper Control. Comes with a picture as well, which says "Sport" & "Eco Pro" over the selector switch - like you say no mention of comfort. From my test drive I thought it said "Normal" as you said (but I've been asleep since then). And now I'm really confused, because in the Price List it says "Drive Performance Control" is standard across the range, but "Performance Control" - Option 2VG is standard on the M Sport but a £125 option on the SE.

Performance Control is rear wheel drive vectoring using the rear breaks
Driving Experience Control is the rocker switch on the console.

I can explain it with some maths....
Drive Performance Control != Performance Control Drive Performance Control = Dynamic Drive Control Drive Performance Control = Normal/Sport/Sport+ switch Drive Performance Control ⊂ VDC

In mine (built July) a fairly standard SE, there is a switch to change modes (can't remember what standard option it is) - available modes are Eco Pro, Comfort (which it starts in) and Sport.
The big problem I have with it - who thought it clever to have the traction control button directly in front of mode switch - several times I have hit it instead of putting into faster responding mode |

I use to disable traction control too when reaching for sport mode then I noticed the sport switch was in direct alignment with the auto shifter lever...it just takes a bit of time to get use to the placement.
