The M40i version of BMW's swoopy X4 improves on the standard xDrive35i, packing a total of 355 horsepower and 343 pound-feet of torque from its turbocharged 3.0-liter straight-six. Buy one and you'll be able to scamper to 60 in just 4.7 seconds. An eight-speed automatic is the sole transmission on offer, and it channels the grunt to a sportier xDrive all-wheel-drive system recalibrated for more rearward bias.
Beyond that, there's the typical array of near-M-spec exterior and interior enhancements. Large wheels – standard 19-inchers or optional 20s – fill out flared wheel arches and sit between more aggressive front and rear fascias. In the cabin, M has fitted its usual oversized steering wheel, along with M-badged door sills.

The result is a powerful sound, individually determined by the driver depending on driving mode and driving situation, perfectly emphasizing the car's sporty character acoustically.
M Performance TwinPower Turbo technology.
The new M Performance TwinPower Turbo inline 6 cylinder gasoline engine also benefits from TwinScroll Turbo technology, the High Precision Injection system, the Double VANOS variable camshaft control system and VALVETRONIC, the fully variable valve control system as standard equipment.
This cutting-edge drive technology in the new BMW X4 M40i guarantees the free-revving thrilling typical of a BMW M engine and its outstanding power delivery.
The integration of the turbocharger into the exhaust manifold also makes a significant contribution to the highly efficient power optimization provided by M Performance TwinPower Turbo technology in the new 6 cylinder inline engine in the new BMW X4 M40i. As internal friction is minimized, the warm-up phase required less time.
* Consumption values were determined on the basis of the EU test cycle, depending on the wheel and tyre sizes.
Excellent driving performance.
Technical enhancements have resulted in the most powerful M Performance gasoline engine to date. The new engine powers the new BMW X4 M40i with 355 hp at between 5,800 and 6,000 rpm. This corresponds to an increase in performance of nearly 18 percent compared to the BMW X4 xDrive35i. At the same time, these internal engine modifications have increased maximum torque by a good 14 percent to 343 lb-ft between 1,350 and 5,250 rpm. The BMW X4 M40i completes the sprint from zero to 60 mph in just 4.7 seconds before hitting its electronically limited top speed of 150 mph.
The increased camber on the double-joint front axle and the strengthening of the wishbones result in increased steering response and more steering feedback. Stiffer springs and reinforced stabilizers on both front and rear axles also reduce roll tendency and optimize driving dynamics. These measures are most effectively supported by the M Performance specific tuning, performed on the electronically controlled damping system.
The variable sports steering, sharpened by M Performance-specific tuning, delivers heightened steering precision; the steering feel is further refined by optimized road feedback.
