BMW’s all-wheel drive system is called xDrive, and its two-wheel drive system is called sDrive.

sDrive – what is it?
As was mentioned above, sDrive designates a BMW as having two-wheel drive and the inability to drive all four wheels. Previously, all BMWs with sDrive had rear-wheel drive, but the most recent BMW X1 has front-wheel drive.
It should be noted that a two-wheel drive BMW won’t always be advertised as having sDrive. When not four-wheel drive versions, the rear-wheel-drive 5 Series and the front-wheel-drive 1 Series are simply referred to as the 5 Series and 1 Series, respectively. When four-wheel drive is requested, the names change to the 1 Series xDrive and 5 Series xDrive. The four-wheel drive BMW X1 is known as the X1 xDrive, while the front-wheel drive version is referred to as the X1 sDrive.
One additional oddity: while just having rear-wheel drive and not being available with xDrive, the BMW Z4 is officially referred to as the Z4 sDrive.
The sporty Z4 is a rear-wheel-drive car, and BMW wants to highlight when certain SUV models are two-wheel drive. These naming conventions may be related to customer expectations about whether a car would be four-wheel drive or not, but they do make things a little more complicated than they otherwise might be.
BMW first introduced xDrive when?
In contrast to the older all-wheel drive technology, the first xDrive cars debuted in 2003. These included the recently released BMW X3 (E83) and the updated BMW X5 (E53). The availability of xDrive spread across the model range in the years that followed, and it is currently offered on the majority of cars.
The 2009 E70 X5M and E71 X6M models were the first BMW M vehicles to feature xDrive. The 2017 F90 M5, which was only offered with xDrive, was the first non-SUV BMW M model to not have rear-wheel drive.
In 2005, xDrive was installed in 50% of BMWs sold in Canada. Rear-wheel drive versions of vehicles that were available with xDrive were no longer offered by BMW Canada as of 2010. For instance, the only BMW 6 Series (F12) 650i option without xDrive in 2012 was the convertible type.

Is sDrive preferable to xDrive?
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.
Does getting xDrive on a BMW make sense?
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.
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.

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
Why is sDrive important to BMW?
BMW xDrive is, you got it, the BMW all-wheel drive system, whereas BMW sDrive is a two-wheel drive system from BMW. Because of their improved performance in less-than-ideal driving circumstances, xDrive models are frequently a little more expensive than their sDrive equivalents.
Does the BMW xDrive have four wheels?
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.
XDrive or Quattro: Which is superior?
Both approaches are really effective and, in all honesty, each has its advantages. Both systems have been used by us quite a bit, and we have always been impressed by how well they function. I’m not sure if one is much superior to the other, but they both have advantages.
My extensive driving of both of them has led me to believe that the BMW xDrive is superior for performance handling on dry tarmac while the Audi Quattro excels in inclement weather. However, both perform admirably in practically any circumstance, demonstrating how far all-wheel drive technology has advanced.
What are the advantages of xDrive?
Should BMW xDrive be included in your next BMW? This movie highlights the benefits of BMW’s 4-wheel-drive system, which is an option on almost all BMW vehicles. so that you can make a choice. BMW xDrive offers two noteworthy benefits:
1. On the one hand, you receive improved driving dynamics. For instance, when driving through a curve, BMW xDrive reduces the power on the wheels closest to the curve. This facilitates side motion and hastens your exit from the curve. Every wheel in an xDrive system receives a distinct distribution of torque.
2. On the other hand, driving safety is increased. The BMW xDrive all-wheel drive system is always in operation, but it only intervenes when it senses possible danger. You are supported in this way, for instance, on gravel, sand, damp, or snowy roads.
Is xDrive more fuel-efficient?
Given that BMWs with xDrive have an additional set of driven wheels, servicing will cost slightly more than conventional rear-wheel-drive models due to the need for more frequent servicing and inspections.
A decrease in efficiency is another drawback of all-wheel drive; as xDrive permanently sends power to all four wheels and adds weight, it will inevitably use more fuel than a rear-wheel-drive model. The rated fuel economy for a BMW 320d SE Drive with rear-wheel drive is 61.4 mpg; when fitted with xDrive, the claimed fuel economy drops to 57.6 mpg.
Can BMW xDrive handle snow well?
It does, indeed. The fundamental idea behind this technology is to provide an all-wheel-drive system, as was already explained. It gives you better traction control underneath your tires by doing this. You can benefit from having extra grip to assist you prevent spinning or skidding in icy weather.
Dynamic Stability Control is a crucial component of the xDrive technology. Once more, this maintains your car’s stability as you drive over snow and ice. If you sense that you are about to lose traction, this is paired with the anti-lock brakes to prevent any spinning and to save you from losing control.
If you drive a BMW equipped with xDrive technology as opposed to one without it, you will undoubtedly notice the difference. To maintain control when driving in winter weather, this technology’s power distribution is crucial.
Of course, there is a small caveat to this. You probably won’t profit if the snow is quite deep because it will be difficult for you to maneuver your automobile through it. Additionally, you still need to take additional safety measures to prepare your BMW for driving in poor snowy weather. Therefore, xDrive functions in the snow, but there are still additional factors to take into account.
Can you disable xDrive?
It is not switchable. This is from the technology manual for BMW. The BMW xDrive all-wheel drive system makes sure your BMW always has the best traction, improving agility and keeping you safely on the road, especially on sharp turns.
