Enthusiasts purchasing for a BMW X3 will assuredly be salivating over the ballistic X3 M fashions. Offered in 473- or 503-horsepower flavors, the Ms are succesful hitting 60 miles per hour within the low-4-second vary and are legit racetrack-capable machines. Problem is, a $70,000 base value is not within the playing cards for everybody. What’s barely extra palatable? How concerning the X3 M40i and its $55,000 beginning price ticket. It may not be as sizzling because the full-fledged M, but it surely is not something to put in writing off, both. 
Boosted six-cylinder Like the king-of-the-hill Ms, the X3 M40i is powered by a 3.0-liter, turbocharged inline-six engine. Its output checks in at a still-punchy 355 horsepower and 365 pound-feet of torque. All that peak twist is on the market for a very long time between 1,520 rpm and 4,800 rpm, leading to laborious launches from stoplights and speedy midrange acceleration for simple expressway merging.

Sending energy to all 4 of the X3’s wheels is the unbelievable ZF-sourced, eight-speed computerized transmission. It gives well-timed gear modifications when left to its personal gadgets, and a worthy handbook shift operate for a extra involving expertise behind the wheel. BMW claims the drivetrain permits the X3 M40i to scoot to 60 mph in 4.6 seconds, besting the Audi SQ5’s 5.1-second and Mercedes-AMG GLC43’s 4.7-second efforts. If you’ll be able to resist the urge to dip deep into the throttle to unleash all the M40i’s grunt, it will return an EPA-estimated 20 miles per gallon within the metropolis and 27 mpg on the freeway. The latter determine I confirmed throughout a roundtrip run from Detroit to Cleveland, observing 26.5 mpg alongside the best way. 
M-level agility  The different a part of the M40i equation is improved dealing with. Upping the 4,300-pound crossover’s dynamics are a rear-biased all-wheel-drive system, adaptive M dampers and greater M Sport brakes with four-piston entrance calipers. On my take a look at automobile, optionally available 21-inch split-spoke wheels wrapped with Bridgestone Alenza tires additionally assist issues fairly a bit.

All of this better-handling tools works collectively to create a luxurious crossover that rips via corners with a great deal of composure and grip.  When the automobile is in Sport mode, the steering is properly weighted and attentive to inputs and helps the X3 change path in a brisk method. As for the brake upgrades, they expertly kill pace in a rush, enabling you to dive deeper into braking zones. No, the M40i is not as hard-core and track-focused because the Ms, but it surely’s loads able to offering backroad thrills on the best way dwelling from work.  Do the M40i’s tighter reflexes imply compromises in trip high quality? Surprisingly, not likely, which stunned me, particularly contemplating the larger wheels and lower-profile tires. Bump stiffness could also be a tad firmer, however with Comfort mode engaged the suspension softens the blow from highway hazards for a more-than-acceptable every day trip high quality.  Bigger wheels with meatier rubber can be found on the X3 M40i.

Massaged styling and tech Compared with the bottom X3, the M40i wears extra aggressive fascias, with bigger air dams up entrance, body-color facet sills and high-gloss black roof rails. Throw within the aforementioned split-spoke wheels and the M40i does units itself aside from its less-potent brethren fairly a bit. Anyone anticipating drastic modifications within the M40i might be dissatisfied. Outside of extra supportive sport seats, a thick-rimmed M steering wheel and a few M logos right here and there, it is a typical BMW cabin. That means environment are cleanly styled, controls are intuitively laid out, supplies are of acceptable high quality and there is a serviceable quantity of room for folks driving in back and front. There’s additionally fairly a little bit of cargo room on provide, with 28.7 cubic ft within the trunk space that grows to 62.7 cubic ft with the rear seats put down. 

On the expertise entrance, a well-sorted iDrive 6 system quarterbacks infotainment features with an 10.2-inch touchscreen and heart console-mounted controller. Both management choices are easy to make use of and responsive whereas working via the onboard navigation, 16-speaker Harman Kardon surround-sound stereo, Wi-Fi hotspot, Bluetooth and Apple CarPlay. Frustratingly, BMWs nonetheless do not assist Android Auto.  BMW’s iDrive system is responsive and intuitive, however nonetheless does not assist Android Auto.

Not lacking from the X3 are quite a few methods to juice up telephones and different good gadgets. Up entrance, prospects can set up an optionally available a wi-fi charging pad, along with having quick access to USB ports and a 12-volt outlet. For people driving in again, there’s one other 12-volter situated on the again of the middle console.

Kicking up the X3’s security story a notch are customary ahead collision warning with computerized emergency braking and entrance and rear parking sensors, whereas a gaggle of different energetic security options can be found. Adaptive cruise management, blind-spot monitoring, lane departure warning with lane-keep help, a 360-degree digicam and a head-up show (HUD) can all be had for an additional price.  How I’d spec it Unlike my $68,520 take a look at automobile that is finished up with choices galore, I’d undertake a extra conservative strategy to constructing my excellent BMW X3 M40i. With the $54,650 base automobile (not together with $995 for vacation spot) as a place to begin, I’d start with a $550 glacier silver metallic paint job identical to the automobile pictured right here. From there I’ll add the $700 adaptive M suspension to have the flexibility to take pleasure in flatter cornering or a extra forgiving trip on the push of a button. The $3,050 Premium Package is a should, principally for the heated entrance seats and steering wheel that’ll assist make winter bearable, and a $500 Driving Assistance Package is one other must-have so as to get blind-spot monitoring. Finally, I’ll throw within the $500 wi-fi cost pad and spoil my ears with the $875 Harman Kardon audio setup, bringing my excellent X3 M40i’s sticker to $61,820. Not too dangerous. Going choices loopy on the X3 M40i can lead to a bloated price ticket.

No pushover I do know the concept of getting the baddest BMW X3 within the land stays the best state of affairs for efficiency automobile junkies as a result of they need essentially the most horsepower and tightest dealing with. And in case your checking account permits for it, then by all means, go nuts and purchase your self an X3 M. But if the M is a little bit too wealthy in your blood, then the M40i is way from a horrible comfort prize. It’s nonetheless darn fast in a straight line, extremely succesful via bends and compliant for regular slogs when it must be. And there’s positively no disgrace in any of that.
