No matter the weather, BMW is making sure you and your loved ones are safe.
The ‘xDrive’ all-wheel drive system is more popular than any other premium brand’s four-wheel drive drivetrain.
According to BMW, in the UK, xDrive outsells Audi’s famous quattro system, Mercedes’ 4Matic range, and all-wheel drive versions of Jaguar’s XF and XJ.
BMW’s AWD System crushes the competition
xDrive is a full-time all-wheel drive system, rather than a part-time drivetrain, which will only fire surplus torque to the opposite axle when the car’s on-board ECU senses any sort of wheel slip.
On regular road and highway, the xDrive predictably follows BMW’s rear-biased model, sending 40% of drive to the fronts, and 60% rearwards. Many have theorized that this can harm AWD performance as less torque is being applied in the location of the engine, killing traction, but BMW isn’t budging on the style and drive characteristics that made the BMW brand what it is today.
The good news? Within one tenth of a second, you can swap torque positions with almost 100% of engine torque being applied to the front or rear axle. Your choice.
“Unlike other all-wheel drive systems, we’ve built xDrive, BMW’s intelligent all-wheel drive system with rear-wheel bias for surefooted grip on slick or uneven roads, without sacrificing the feel of rear-wheel drive.” -BMW
The xDrive sends power to the wheel or wheels with the surest footing—and it does so in milliseconds. This type of technology is a crucial safety feature in new and future models.
The first BMW to fully utilize the AWD were the E30 325iX ‘Allrad’ from 1985, but the company’s own AWD system can be found in everything from the 1-series to the luxurious 7-series.
BMW’s xDrive uses a multi-plate clutch system rather than the viscous coupling found in most all-wheel drive cars. The xDrive is electronically controlled using the clutch system to vary torque to the axles every 0.1 seconds, with the capability to send 100 per cent of torque to one axle.
Yes, it changes automatically based on road conditions.
The xDrive’s electronically controlled multi-plate clutch, rather than slower-to-react hydraulic fluid, will revert back to the 40:60 split after normal driving conditions have been established.
