Overview

xDelete offers not only the possibility, to turn your xDrive ON or OFF, but also lets you customize its behavior. The settings available are ON, OFF, Sport, Snow and Custom, which lets you dial-in the power transferred to the front by yourself. Please note, that the xDrive AWD System is mainly a clutch, that can be gradually opened and closed to regulate the maximum torque towards the front wheels. It is not an active differential, like found in off-road vehicles. That means the maximum power split between the axles is 50/50 Front/Rear, while the minimum is 0/100 Front/Rear. It is technically not possible to send more than 50% of the power to the front wheels with this system. The Stability System (DSC) and the Transfer-Case unit (VGSG) coordinate to set the max. torque which is transmitted to the front wheels, depending on the driving situation. The main inputs are:


xDrive ON

Your car will drive completely stock. The maximum power transmitted to the front wheels depends on your type of Transfer Case, but usually is around 1100 – 1300 Nm (800 – 950 ft lb). xDrive is setup to maximize traction and keep the car stable at all cost.

Do NOT run this configuration, if you are running a staggered wheel setup. For more info, look at our FAQ, regarding running staggered setups or running the car on a dyno.


xDrive OFF

Your car will drive like a RWD vehicle. The power transmitted to the front is kept at 0 Nm at all time. This means the power split between front and rear is 0/100 Front/Rear. Please note, that the xDrive clutch is submerged in oil and therefore a small amount of power will always reach the front wheels, even if the clutch is fully open. For instance, on a lift all 4 wheels will still turn, but you can easily hold the front wheels still with your bare hands.

Do NOT attempt to test this yourself, using your bare hands. We tested it already for you. A moving wheel has a lot of inertia, you can still hurt yourself badly.

This is the only recommended configuration to use staggered wheels with. For more info, look at our FAQ, regarding running staggered setups or running the car on a dyno.


xDrive Sport

The xDrive system is setup to have a permanent low front-bias. Even if the rear wheels are spinning, the front wheels will only receive limited power to avoid understeer on wet and dry roads. This setting will shift your car to be more oversteery (compared to stock) but will still generate enough traction on corner exits to stay full on throttle, even in 1st and 2nd gear. Please note: This setting is NOT intended to be used for Burnouts or on 2WD-Dynos! The Transfer Case permanently monitors the relative speed between Front and Rear-Wheels and will put your car to limp mode if there is too much relative movement over extended periods. It is safe to use for normal road use, driving on racetracks and for drifting sessions.

Please use our Live-Data-Feed to monitor your Clutch-Stress while experienced driving. You should never exceed 50% for extended periods.

Do NOT run this configuration, if you are running a staggered wheel setup. For more info, look at our FAQ, regarding running staggered setups or running the car on a dyno.


xDrive Snow

The Snow setting works similar to the “Sport” setting but limits the max. power to the front wheels even more, to accommodate the even lower friction on Snow. The Snow setting will make your car behave mostly like an RWD vehicle on Snow, but will give you added traction, while keeping understeer to a minimum. This setting also allows small burnouts, but must not be used on 2WD- Dynos.

Please use our Live-Data-Feed to monitor your Clutch-Stress while experienced driving. You should never exceed 50% for extended periods.

Do NOT run this configuration, if you are running a staggered wheel setup. For more info, look at our FAQ, regarding running staggered setups or running the car on a dyno.


xDrive Custom

You can configure your Lock-Up rate from 0-100%. 100% is similar to stock, while 0% is similar to xDrive OFF. Snow and Sport settings are in between. (approx. 20% and 50%) Please use the custom setting with caution and use our Live-Data-Feed to monitor your Clutch-Stress. Also obey the common rules, mentioned with the Snow and Sport setting. Do NOT drive staggered wheels with any setting above 0%.

Please use our Live-Data-Feed to monitor your Clutch-Stress while experienced driving. You should never exceed 50% for extended periods.

Do NOT run this configuration, if you are running a staggered wheel setup. For more info, look at our FAQ, regarding running staggered setups or running the car on a dyno.
