BMW is poised to electrify its performance SUV lineup, with the next-generation X3 M and X4 M set to inherit the high-octane quad-motor drivetrain from the upcoming all-electric M3. This move marks a significant leap in performance for these models, promising power figures rivalling BMW’s flagship sedan in a more spacious and versatile package.
Electric Performance Without the ‘i’ Badge
According to insider reports from the Bimmerpost forum, BMW plans to drop the ‘i’ prefix previously associated with its electric vehicles. The high-performance versions will be branded simply as the X3 M and X4 M, signaling a shift towards integrating electric power into its core M lineup.
Quad-Motor Power: 800 to 1000 HP
The X3 M and X4 M will reportedly share the same quad-motor setup as the electric M3, which is expected to be available in both sedan and wagon configurations. This powertrain is rumoured to deliver between 600kW and 746kW (800hp to 1000hp), significantly boosting performance. While the M3 will get a unique battery pack, the X3 M and X4 M will utilise the 108kWh battery already employed in the iX3 50 xDrive.
Range Trade-Off for Power
The increased demands of the M drivetrain will inevitably impact range. While the iX3 50 xDrive currently achieves up to 805km (WLTP), the M variants are expected to see a reduction in range due to the higher power output.
Production and Timeline
Manufacturing for both the X3 M and X4 M will take place in Debrecen, Hungary, alongside their standard iX3 and iX4 counterparts. Production is slated to begin by the end of 2027. Spy shots of the iX4 and electric M3 have already surfaced, but images of the i3 wagon or M variants of the iX3 and iX4 remain unreleased.
Interim Performance Boost: The M60 Variant
For those eager for an immediate performance upgrade, BMW is also planning an M60 variant for the iX3 in the near future. Currently, the most powerful iX3 model is the 50 xDrive, which boasts a dual-motor system producing 345kW (469hp) and 645Nm (476lb-ft). Despite its hefty 2360kg weight, it can accelerate from 0-100km/h in 4.9 seconds.
The move to electrify the X3 M and X4 M aligns with BMW’s broader strategy to transition towards electric performance vehicles. This shift not only enhances the M brand’s image but also prepares it for a future where high-performance driving is increasingly defined by electric power. The integration of the quad-motor setup demonstrates BMW’s commitment to delivering cutting-edge technology without compromising on the thrill of driving.
