BMW’s long list of vehicles grows yet again with the addition of this, the M40i version of the X4 Sort Activity Coupe. Yep, to compete better with Audi and Porsche, along with the other BMW models already sold, the X4 M40i brings more sport and performance to the table.

More power, better handling, better braking, and some restyled exterior trim work gives the M40i its advantages over the standard X4. Think of the M40i as BMW’s almost an M version of its third smallest crossover.

The X4, like its big brother the X6, is categorized by its sharply sloped rear roof section that gives the vehicle a coupe-like appearance despite its SUV-like proportions. While not the most practical, the design is certainly sportier than the block-ish shape of the X1, X3, and X5,

Like other M Performance models, the X4 has an upgraded version of its original engine. In this case, it’s the familiar 3.0-liter inline six-cylinder with forced induction thanks to turbocharging. The result of BMW’s massaging is an extra 55 horsepower and 43 pound-feet of torque. Matching the extra power are performance-oriented Michelin tires wrapped on your choice of 19- or 20-inch wheels motivated by a standard AWD system. But more on those details later.

The M40i will go on sale in February 2016 in the U.S. for a price BMW has yet to release. Expect that information to come when the M40i gets its formal introduction at the 2015 LA Auto Show.

Updated 01/13/2016: BMW brought the X4 M40i at the 2016 Detroit Auto Show and announced North American prices for the sports SUV. The model will go on sale in February 2016 at a starting price of under $60k.

It will take an expert’s eye to spot the upgrades to the M40i, though there are differences nonetheless. The M Performances option adds satin chrome accents just below the fog lights within the grille. BMW calls the color “Ferric Grey” and it’s also found on the side mirror caps. For those who order the optional 20-inch M Light-alloy, double spoke wheels, the Ferric Grey also appears there.

Around back, the biggest difference will be the M40i badging on the tailgate. Besides that, the tailpipes are finished in a Black Chrome color.

Beyond aesthetics, The M40i comes standard with 19-inch, double spoke alloy wheels wrapped in your choice of all-season run-flat tires or performance run-flats. Optional are those 20-inch wheels paired with high-performance Michelin Pilot Super Sport tires.

Like the outside, the interior retains most of the X4’s original design. The M40i option adds an M leather-wrapped steering wheel, M gear shift lever, sport seats, and door sills with “X4 M40i” lettering. That same lettering also appears on the instrument cluster.

The remainder of the dashboard is BMW as usual. The iDrive screen is perched within the dash at the top of the center stack. Small buttons and knobs control the HVAC functions while an even smaller knob controls radio volume. Most other inputs are done by the large iDrive controller. Much improved over years past, the iDrive system does everything from navigation and radio to vehicle settings and oil change reminders.

Thanks to the X4’s sloping roof, rear-seat headroom and cargo room are cramped. It is perhaps easiest to consider the X4 a hatchback with big wheels and a somewhat tall ground clearance.

Now to the important stuff. As mentioned before, the M40i comes powered by the same 3.0-liter TwinPower inline six-cylinder as the standard X4, but is tuned to give 55 more horsepower and 43 more pound-feet of torque. The tune includes increased boost from the turbo matched with high-flow fuel injectors. An aerodynamically tuned air intake manifold, along with a free-flowing exhaust system helps with breathing, while a separate oil cooler keeps temperatures in check.

The M40i comes standard with BMW’s xDrive AWD system and the eight-speed automatic transmission remains unchanged.

All told, the engine kicks out 355 horsepower between 5,800 and 6,000 rpm and 343 pound-feet of torque from 1,350 through 5,250 rpm. That’s enough to push the M40i to 60 mph in 4.7 seconds – down from 5.2 seconds in the standard X4. Top speed is governed at 150 mph.

Matching the extra power is a sport-tuned suspension and meatier brakes. Stronger springs and stabilizers help keep body roll to a minimum while increased camber on the front wheels helps with turn-in and steering feel. Adaptive dampers from the M Performance department keep road imperfections from slowing the M40i’s roll, while giving it a stiffer ride for better handling.


The BMW X4 has not been crash tested by either the IIHS or NHTSA at the time of this writing, but the crossover does include plenty of active and passive safety systems. They include front, side, and overhead airbags; seatbelt pretensioners, anti-whiplash head restraints; and all the typical electronic stability control features found in modern crossovers.

The Macan is an exciting new offering from Porsche. Based on the competent Audi Q5 platform with a bevy of Porsche-specific upgrades, performance is blistering, and the Macan has already been touted as offering a better all-around driving experience than the Cayenne. Performance is stout, with a choice of two twin-turbocharged, V-6 engines coupled with the acclaimed, seven-speed PDK transmission. Power is routed to the ground via Porsche’s rear-biased all-wheel-drive system.

The base Macan S makes 340 horsepower from its 3.0-liter V-6, while the Macan Turbo uses a larger, 3.6-liter version that increases output to an even 400 horsepower. Prices start at $49,900 for the base Macan S, while the Macan Turbo beings life at a cool $72,300. Expect, in typical Porsche fashion, to pay an exorbitant amount more once the option list starts filling up.

Don’t discredit the Q5 line simply because Porsche tweaked the platform with its own version. The SQ5 takes the already agile Q5 and adds the brand’s supercharged, 3.0-liter V-6. Classy styling upgrades and special badges complete the package.

In the SQ5 application, additional ponies have found their way in, with 354 being the official horsepower rating. The torque rating is a hefty 347 pound-feet. Power reaches the ground via Audi’s legendary quattro all-wheel-drive system, and cog-swapping duties are handled by the praised ZF eight-speed automatic transmission, re-tuned for duty in the SQ5 for faster and crisper shifts.

Pricing for the SQ5 begins at a not-too-bad $52,795. Seeing as this is the top-dog offering in the Q5 lineup, compared with the previously mentioned Porsche Macan, this is a relative bargain. This is also very competitive with the current BMW X4’s pricing.

The upgrades BMW has fitted to the X4’s sporty edition should make it a great stepping stone between the regular X4 and the more purpose-built X5 M or X6 M. This M Performance package will attract folks looking to canyon carve on their way to work while still hauling their family to grandma’s house on the weekends. The M40i isn’t too outrageous, but is just potent enough to make a statement. And that seems to be working for BMW’s other M Performance models.

The newly developed M Performance TwinPower Turbo inline 6 cylinder gasoline engine for the new BMW X4 M40i combines high performance with exemplary fuel economy. Accordingly, the lightweight, thermodynamically optimized aluminium engine has been constructed with a closed-deck design. In this type of construction, the water jacket surrounding the cylinders is sealed at the top, which endows the crankcase with an exceptionally high degree of stiffness.

Building on heritage: The BMW TwinPower Turbo engine.
The drive unit powering the new BMW X4 M40i is based upon the three-liter, inline 6 cylinder engine in the BMW X4 xDrive35i. The chassis has been optimized using a forged steel crankshaft, pistons with a modified top ring, crankshaft bearings and high performance spark plugs in its 6 cylinder inline engine with M TwinPower Turbo technology.

In addition to a higher level of turbo boost pressure and an increase in the amount of fuel injected, the engine has been fitted with an aerodynamically tuned air intake manifold as well as an exhaust system optimized both in terms of back pressure and sound characteristics in order to enhance performance. A separate oil cooler guarantees that the optimum operating temperature of this extremely powerful engine is maintained under all driving conditions.
The distinctive exhaust system fitted to the new BMW X4 M40i is unmistakable with tailpipes on both sides finished in Black Chrome. The radical technical changes include, an intelligent valve control, a back pressure-optimized double-flow exhaust system fitted beneath the floor of the vehicle, as well as resonator tuning specific to M Performance. 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.

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.

Sport Automatic 8-speed STEPTRONIC as standard.
The 8-speed STEPTRONIC sports transmission, fitted as standard equipment in the new BMW X4 M40i, is responsible for the transmission of the energy supplied by the most powerful M Performance gasoline engine to date, making a significant contribution to the dynamics of this M Performance vehicle. The M Performance-specific tuning of the gear shift programs, which features distinctively sporty shifts and higher downshift spontaneity throughout the entire range of engine speed, was specially adapted to the engine characteristics. Sporty, direct powertrain connectivity is achieved by carefully avoiding converter slip outside of gear changes. In addition, the 8-speed Steptronic sports transmission has Launch Control as standard. With this easy-to-use system, an ambitious driver is able to optimally accelerate his BMW X4 M40i under all conditions. For a decidedly sporty driving style, the 8‑speed Steptronic sports transmission can also be controlled via paddle shifters mounted on the steering wheel. In classic fashion, when in manual mode the selected gear is maintained, even when the engine speed limiter has been triggered. In addition, with its compact design, low weight and its optimized efficiency, this transmission makes a significant contribution to reducing both fuel consumption and emissions.

xDrive - BMW’s intelligent all-wheel drive system.
Like all of the BMW X4 models, the BMW X4 M40i is fitted with intelligent BMW xDrive all-wheel drive. With Performance Control as standard, the system regulates the variable distribution of drive torque between the two rear wheels. These systems help to achieve a unique level of dynamics, agility and traction. Regardless of the road surface, the vehicle follows the line the driver intends far more precisely and requires noticeably fewer steering corrections. Furthermore, the BMW xDrive fitted to the BMW X4 M40i has been configured to place emphasis on the rear wheels, a typical characteristic of BMW M Performance driving dynamics.

Michelin Pilot Super Sport tires– for ideal road contact.
Instrumental to the excellent driving dynamics of the new BMW X4 M40i are the appropriate tires. Exclusively available for the new BMW X4 M40i are the optional new two-tone 20-inch double-spoke light-alloy wheels (front 8.5 J x 20, rear 10 J x 20) fitted with Michelin Pilot Super Sport tires. This Ultra High Performance tire mix (front 245/40 R20, rear 275/35 R20) guarantees an even better feel for, and a measurable increase in the driving dynamics.

As standard equipment, the BMW X4 M40i is fitted with a 19-inch double-spoke light-alloy wheels with either all-season run-flat tires (8.5 J x 19, 245/45 R19) or performance run-flat tires (front 8.5 J x 19, 245/45 R19; rear 9.5 J x 19, 275/40 R19 ) axle.

In view of the performance of the new BMW X4 M40i, the braking system also had to be upgraded. The increased size of the brake discs on the front axle and the performance-oriented brake pads on all four wheels ensure that the new BMW X4 M40i can be outstandingly decelerated, in even the sportiest of driving conditions.

Individualization and Design.
The stretched, powerful lines of this Sports Activity Coupe are further emphasized in the new BMW X4 M40i with selectively applied Ferric Gray metallic accents, that clearly sets this vehicle apart from the other BMW X4 models. For example, the exterior mirrors as well as the vertical slats of the famous BMW kidney grille are painted in exclusive Ferric Gray metallic. The same color also adorns the new aero design element in the large air intakes located on the far outer edges of the front apron. In addition, the exclusivity of the BMW X4 M40i is subtly underlined by the model lettering in chrome.

From the rear, the new BMW X4 M40i is immediately recognizable. At first glance, the wide, flat rear end with the L-shaped LED rear lights and the aggressive diffuser optics affirms the vehicle’s excellent driving dynamics. Two tailpipes are mounted on the left and right at the rear and the sport exhaust system finished in Black Chrome also suggest the extraordinary performance potential of the BMW M Performance model which is confirmed by the powerful sound of the engine.

The extroverted appearance of the new BMW X4 M40i is supplemented by the exclusive, optional 20-inch M double-spoke light-alloy wheels in two-tone Ferric Grey metallic, with highly polished, sculpted faces. Together with the characteristic two-part contour line, the muscular flanks and the accurately modelled C pillars, these illustrate once again the excellent dynamic credentials of BMW M Performance automobiles.

The sporty, exclusive interior of the new BMW X4 M40i also emphasizes its typical BMW M Performance pedigree. The door sills bear the “X4 M40i” lettering, which also appears on the instrument cluster when the vehicle is unlocked and remains visible when driving. Navigation instructions and vehicle status messages are superimposed over the lettering as required. This dynamic impression is rounded off by the new standard M leather steering wheel with shifter paddles and the M logo on the selector lever of the 8-speed STEPTRONIC Sport automatic transmission.

The new BMW X4 M40i is extensively equipped when ordered as a standard vehicle. 8-speed Sport automatic transmission, Dynamic Damper Control, Variable Sport Steering, Performance Control, Park Distance Control front and rear, Xenon adaptive headlights and LED fog lights are all standard, as well as Sport seats, M leather steering wheel and 19-inch M light-alloy wheels.
