2019 BMW X4 M Performance Review And Buying Insights

The 2019 BMW X4 M marks a bold evolution in BMW’s lineup, fusing the practicality of a crossover with the razor-sharp dynamics of a sports car. Launched as part of the second-generation X4 family, this M variant prioritizes adrenaline-pumping acceleration and track-ready handling while retaining everyday usability. With its aggressive styling and advanced M xDrive system, it challenges traditional SUVs to deliver supercar-like thrills.

Design and Exterior Highlights

The X4 M’s exterior commands attention with its fastback silhouette, flared wheel arches, and massive air intakes that hint at its performance credentials. Measuring longer and wider than its predecessor, it boasts a more planted stance, enhanced by 20-inch or optional 21-inch wheels shod in high-performance Michelin Pilot Sport 4S tires (255/40 front, 265/40 rear). The aerodynamic profile not only looks striking but also aids high-speed stability, contributing to a top speed exceeding 155 mph in ungoverned tests. Aggressive bumpers, quad exhaust tips, and M-specific badging complete the look, setting it apart from standard X4 models.

• Bold front fascia: Large kidney grilles and sculpted hood for an imposing presence.
• Sporty rear: Diffuser and twin tailpipes emphasizing power.
• Improved dimensions: Added length boosts rear space without sacrificing agility.

This design philosophy appeals to drivers seeking a vehicle that stands out in a sea of bland crossovers.

Engine and Powertrain Excellence

At the heart of the 2019 BMW X4 M lies a hand-built 3.0-liter twin-turbo inline-six engine, delivering 503 horsepower in Competition guise at 6250 rpm and 600 Nm of torque from 2600-5950 rpm. Paired with an eight-speed automatic transmission and M xDrive all-wheel drive, it propels the 1970 kg beast to 0-100 km/h in just 4.1 seconds (claimed), making it the quickest X-series model ever. The system offers 4WD and 4WD Sport modes, with the latter reducing front axle torque for playful rear-biased handling, enabling controlled power oversteer.

For those opting for the M40i variant, a detuned version of the same engine produces 355-382 hp with 365 lb-ft torque, achieving 0-60 mph in 4.6 seconds. Real-world tests confirm its immediacy, with quarter-mile times around 14.8 seconds at 94 mph.

The powertrain’s seamless shifts and torque vectoring differential shine in dynamic driving, though some note the engine’s synthetic soundtrack lacks the raw character of rivals.

Handling and Driving Dynamics

BMW engineers refined the X4 M’s chassis with firmer springs, adaptive dampers, and anti-roll bars, reducing unsprung mass for better compliance over rough surfaces compared to the first-gen model. The result is remarkable cornering prowess: skidpad grip reaches 0.90 g for M40i and higher for full M, with precise steering that’s weighty yet accurate. In Sport+ mode, the active M differential locks fully, enhancing turn-in and allowing drifts on wet surfaces—a rarity for SUVs.

Reviewers praise its bend-fiddling ability despite the size, with rear-biased AWD injecting fun without compromising traction. M Sport brakes with blue calipers provide firm, modulated stopping power, halting from 70-0 mph in 155-180 feet. However, the steering offers heft over feel, and the ride remains stiff in firmer settings.

• Track-ready poise: Rigid chassis and adaptive suspension balance sport and comfort.
• Playful rear end: Throttle lifts induce oversteer, rewarding skilled drivers.
• Mode versatility: Comfort for daily drives, Sport+ for circuits.

Interior Comfort and Technology

Inside, the X4 M mirrors the X3’s upscale cabin but with M touches like sports seats, carbon fiber trim, and a flat-bottomed wheel. Rear legroom improves by an inch, and cargo space hits 19 cubic feet behind the seats—adequate but compromised by the sloping roofline. Materials feel premium: soft leather, diamond-quilted accents, and a intuitive iDrive infotainment with touchscreen and digital cluster. Standard kit includes adaptive cruise, heads-up display, and Harman Kardon audio.

While front space is generous, rear headroom suffers for taller passengers entering via the low door aperture. The cabin’s quality and ergonomics earn high marks, making long hauls enjoyable.

Fuel Economy and Practicality

EPA ratings for the M40i stand at 22/29 mpg city/highway (25 combined), with observed figures around 19-33 mpg. The full X4 M thirstier at ~19 mpg average, reflecting its performance focus. Highway range exceeds 480-560 miles. Practicality lags behind boxier X3 M: less cargo (10 cu ft less) and tighter rear access, prioritizing style over utility.

From £65,735 on-road in the UK or $164,900 in Australia, it’s premium-priced, competing with Porsche Macan but facing cheaper X3 M alternatives.

Pros, Cons, and Rival Comparisons

Versus Porsche Macan Turbo, the X4 M offers similar pace but more rear room; against Audi RS Q5, it edges in fun factor. Ratings vary: 3.5/5 from WhichCar, 7/10 from Carwow.

Ownership Experience and Reliability

BMW’s M models emphasize driver engagement, with the X4 M suiting enthusiasts over families. Maintenance costs are high due to performance parts, but build quality impresses. Launched summer 2019, updates came in 2021; replacements loomed post-2021. Fuel and tire wear demand budget consideration.
