The 2026 BMW i4 arrives with a suite of clever electrical revisions that coax more miles from each charge and, in range-topping form, deliver super-saloon muscle. Engineers have fitted silicon-carbide semiconductors to the inverter modules, trimming energy losses during every power pulse. The outcome is a consumption cut of roughly five per cent, nudging the single-motor eDrive35 towards an estimated 279 miles and the eDrive40 towards about 334 miles on the EPA cycle—figures that place the i4 firmly among the efficiency leaders in its class.

Performance hunters will gravitate to the newly christened i4 M60 xDrive. Dual motors now combine for 601 bhp, a healthy 57-horsepower lift over last year’s M50. With both axles hauling, BMW forecasts 0–62 mph in 3.7 seconds, yet recent Bavarian timing habits suggest the stopwatch could reveal even sharper splits. Torque remains undisclosed, but the brand’s traction algorithms are tuned to portion it out with clinical precision, ensuring the M60 launches cleanly and surges out of bends with minimal slip.
Under the skin, chassis calibrations mirror the powertrain’s extra verve. Spring and damper maps have been reworked to handle the added output while preserving the supple ride that sets the i4 apart from many firm-riding rivals. Minor aerodynamic tweaks around the front apron and rear diffuser subtly reduce drag, complementing the inverter upgrades to eke out precious watt-hours on the motorway.

The cabin retains BMW’s curved dual-screen cockpit, now running Operating System 8.5 with expanded over-the-air update capability. Occupants benefit from wireless phone mirroring, a crisp head-up display and the optional panoramic roof that floods the interior with light. Exterior differentiation is minimal—BMW prefers understatement—but keen eyes will spot fresh wheel designs and a new badge on the bootlid of the flagship M60.
Official EPA figures and full UK specifications will be confirmed nearer the car’s fourth-quarter market launch, yet the broad strokes are clear: the 2026 BMW i4 blends longer legs with a mighty power punch, strengthening its case as the brand’s most compelling compact electric fastback to date.
