The xDrive technology boosts safety in low-traction conditions in addition to fostering assurance during enthusiastic driving, particularly around corners at faster speeds. The technology seeks to maximize horsepower without losing any power trying to regain traction on the road’s surface.
The xDrive system decreases power to the inner curve wheels when navigating a curve. The driver can exit the turn more quickly thanks to this movement, which also assists the vehicle’s sideways momentum.
Oversteering or understeering could occur when a motorist enters a curve with too much power coming to the drive wheels. Depending on the conditions, the xDrive system switches the power to either the front or the rear axle.
Drive power to the front axle is decreased at the first sign of understeering. More power is sent to the front axle if oversteering is discovered. Vehicle stability returns to normal as a result of this dynamic redistribution of power before the driver even realizes a change has taken place.
In order to keep track of the state of the road, the xDrive system collaborates with Dynamic Stability Control (DSC) and gathers data from the system’s wheel-speed sensors. Additionally, when there is a traction difference between the two sides of the car and wheel spin is about to happen, the system provides brake force.
Together, these features enable xDrive to provide the most enjoyable performance driving experience possible.
Describe xDrive.
All-wheel drive is the designation for xDrive. During typical driving, the standard system distributes 40% of the power to the front wheels and 60% to the rear. In order to increase grip and keep the automobile stable, power can be transferred forward, backward, or to specific wheels when sensors detect wheel slide. As a result, there should be reduced chance of unintended traction loss in corners, during rapid movements, or in low-grip settings, including off-road, making xDrive BMWs better able to maintain the road.
While many other all-wheel drive systems function hydraulically, xDrive employs a multi-disc clutch that is electronically controlled, which is lighter and has a faster rate of power redistribution. BMW’s Dynamic Stability Control (DSC) system of software and sensors can send nearly 100% of the engine’s power to either axle under extreme circumstances in just 0.1 seconds. This procedure is continuously monitored and adjusted by the system. On BMW performance models, xDrive can be configured to distribute power primarily to the rear wheels, shifting it only when there is wheel slip. This ensures that the vehicles can handle the enormous power and torque outputs being supplied today while simulating the traditional rear-wheel drive driving characteristics for which BMWs were known.
Dynamic Performance Control, a characteristic of these more potent BMW models, uses the xDrive system’s electronically controlled clutch plates to accelerate the wheel opposite the one that is spinning. It collaborates with the DSC system, which uses braking pressure to assist the spinning wheel in regaining control.
For Rear-Wheel Drive Vehicles, xDrive
The xDrive versions of BMW’s rear-wheel drive cars (including their sports utility vehicles, the X3 through the X7, but not the most recent X1 and X2 models) distribute 40 percent of available torque to the front wheels and 60 percent to the back wheels during normal driving.
An solitary axle can get almost all of the available torque in an emergency. In order to maintain as much of the classic BMW “rear wheel biased” performance experience, higher performance models equipped with Dynamic Performance Control start with less power going to the front wheels.
The M240i xDrive, for instance, has a transfer case that is physically connected to the excellent 8 speed ZF automatic transmission. The clutch pack, which can send torque to the front or back axles, is part of the transfer case.
The transmission is skewed to the left, and so is the driveshaft for the front wheels. The front wheels are driven by a differential after it travels ahead. Using the area needed for a typical rear-wheel-drive car, a propshaft transfers power to the rear differential.
ONLY FUN DRIVING KNOWS BAD WEATHER, according to Joy.
The BMW xDrive all-wheel drive technology makes the most of the traction available to each axle. When coming out of curves, your BMW accelerates steadily. Dynamic Stability Control (DSC) kicks in when more power needs to be supplied to the road, especially in challenging conditions. The device not only increases traction but also detects the early warning indicators of oversteering and understeering. It transfers up to 100% of the engine’s power to the front or rear axle via the transmission and an electronically controlled multiple-plate clutch in less than a tenth of a second before switching back to the standard 40:60 distribution ratio. BMW uses this technology to give all-wheel drive vehicles all the advantages of rear-wheel drive, including accurate handling, optimal cornering, and a distinct separation between the engine and steering.
How does xDrive AWD work?
All-wheel drive (AWD) is a common term used to describe how cars can maintain traction in poor weather conditions. BMW’s special all-wheel drive system, known as xDrive, helps to underline that it differs from other all-wheel drive systems now available on the market.
The torque generated by the engine is distributed evenly between the front and back wheels on conventional four-wheel-drive systems. While xDrive does transfer torque to the front and rear axles, it does so in a variable manner. In other words, the amount of torque that is applied to the front or rear wheels when the situation changes. Because of this cutting-edge technology, drivers have exceptional road-holding and handling, which makes driving on curving roads enjoyable rather than unpleasant.
A multi-disc clutch that is built into the drivetrain is the foundation of the xDrive technology. The clutch is managed by sophisticated electronics, which constantly adjust it to account for changes in the road. Because those adjustments to the front and rear axles’ torque distribution take place in just a fraction of a second, the system is perfect for handling unexpected traction losses. The capacity to send various quantities of power to the various axles contributes to constant stability. The xDrive technology can switch all power to the opposite end of the vehicle in extreme situations where one set of wheels completely loses grip.
For instance, a BMW might be driving down a road in the winter when everything appears to be in order. Unnoticeable to the vehicle, a patch of black ice is located on an overpass. Power is immediately transmitted to the back wheels rather than the car losing control once the front wheels contact the patch. Torque is instead applied to the front axle when the other end of the vehicle crosses the slick ice, assisting in maintaining control throughout the entire journey.
This design outperforms several other all-wheel-drive systems as well as conventional four-wheel-drive systems in terms of performance. In a conventional setup, when one set of wheels loses traction, the power that would have ordinarily gone to them is completely lost, leaving the vehicle operating at half of its typical output. With BMW’s xDrive, that power is switched to the other axle, allowing the vehicle to maintain its previous speed. This makes driving easier for the driver by ensuring greater stability and predictability regardless of the state of the road.
Even on completely dry roads, most people probably aren’t even aware of how much better steering performance on BMWs with xDrive is. The majority of cars will understeer in curves, pushing them out of their lane and necessitating the driver to correct the situation in order to avoid a head-on accident or possibly losing control and spinning out. With the xDrive technology, as the car curves, the sensors will shift some of the engine power from the front to the rear axle. Without the driver having to take any action, understeer is fully eliminated, giving them maximum control without having to slow down.
While everyone considers the benefits of BMW’s xDrive in the winter, you should be aware that you may take advantage of it year-round. It’s the ideal approach to get The Ultimate Driving Machine to function at its peak, not take the fun out of driving.
Is the BMW xDrive any good?
In BMW vehicles, the all-wheel drive system known as xDrive is used continuously. BMW vehicles’ xDrive system guarantees exceptional cornering performance. The vehicle’s agility and dynamics on any surface are improved by the smooth distribution of torque between the rear wheels, traction, and handling. This enables you to negotiate curves very smoothly and precisely.
The ABS (Antilock braking system) and DSC automatically detect over- and under-steering, and the system immediately responds by distributing up to 100% of engine power to the front or rear axle depending on the scenario.
BMW’s rear-biased hallmark typically distributes 40% of the drive to the front and 60% to the back.
What does “xDrive” in my BMW mean?
You should see the rear transfer box/differential and a drive shaft leading to each of the rear wheels if you peek beneath the back of the XDrive. SDrive solely has front-wheel drive.

Which BMW sDrive or xDrive is superior?
Models with sDrive are often somewhat more efficient, though xDrive will enhance your car’s handling and acceleration. Torque vectoring technology is available in both options, and neither will leave you wanting more, but only one will feel completely correct for you.
Is BMW xDrive a permanent AWD system?
xDrive is an all-wheel drive system that operates continuously, as opposed to systems like VW’s Haldex differential that only send excess torque to the opposing axle when the car is in motion. ECU detects wheelslip
Does BMW xDrive require maintenance?
As far as I’m aware, the xDrive system doesn’t need any maintenance. There is no upkeep necessary. The VTG unit, along with ZF8, is full to the brim. No upkeep necessary
Does xDrive actually matter?
Cost is an issue with xDrive. Again using a 3 Series as an example, the 320i M Sport starts at PS36,785, but adding xDrive raises the price to PS38,610, representing a PS1825 premium. Furthermore, the xDrive model will cost more to maintain and operate, with a highest fuel economy rating of 41.5 mpg compared to the two-wheel-drive car’s 44.1 mpg. If you travel a lot, this can add up quickly.
When you consider that a 3 Series with winter tires—complete with their unique tread design and incredibly soft compound—will be even more capable on the slick stuff than an xDrive model on ordinary rubber, the cost will be more difficult to bear.
BMW xDrive maintains the agile handling for which BMW is renowned while providing four-wheel drive traction. This is due to the fact that the xDrive system distinguishes cars like the 3 and 5 Series from the quattro system found in the majority of Audi models by having a bias toward rear-wheel drive.
If you frequently travel in snow, it might be wise to get a BMW with xDrive. The car’s four-wheel drive system effectively doubles its degree of traction, helping you to maintain momentum on slick roads where a rear-wheel drive BMW might bog down.
The model will decide. A 520i petrol should be able to drift at low speeds in the wet, whereas an M5 performance saloon with xDrive has enough power to lose traction even on a dry road.
