BMW isn’t done tweaking their M3 and M4 performance duos yet. Taking up the dynamics and agility up a notch, the brand has introduced xDrive on both models, spanning the latest model generation with six vehicles. And it’s not just the addition of model line ups, with AWD being introduced the cars have gained performance as well. Now that’s what we like to hear from the M division.
The M xDrive system uses an electronically controlled multi-plate clutch in the transfer case for smoothly adjustable, fully variable distribution of drive torque between the front and rear wheels. The all-wheel-drive system has a rear-biased setup in classic M style. Normally, the drive power is channeled entirely rearwards, with the front wheels only being brought into play when the rears cannot feed any more power to the road.
The AWD system is further complemented by a redesigned double-joint spring strut front axle that also features a specially adapted front axle geometry and an individually tuned steering ratio. M xDrive also allows the driver to tailor the all-wheel-drive system’s characteristics and performance. There is a choice of three different power transmission modes – in the default 4WD setting, the all-wheel-drive system offers maximum traction, activating 4WD Sport mode directs an even greater proportion of the engine’s torque to the rear wheels and then there’s the option to switch off the DSC system altogether and engage 2WD mode, turning this into a smile-inducing drift monster.
The improvements in traction, handling stability and agility are brought about by the combination of M xDrive and Active M Differential. As a result, both the performance duos in their Competition trim can sprint to 100kmph in 3.5 seconds, making them 0.4 seconds quicker here than their rear-wheel-drive equivalents.
Wait, there’s more good news. The BMW M4 Convertible joins the model range later this year, expanding the brand’s performance car offering. You gotta stay tuned for more updates on that.
