BMW always liked experimenting with new products which might not be as practical as the outgoing models on its lineup. The X6 was a fruitful result of the brand’s experimentation on SUVs to make them more appealing and sporty visually if not in terms of performance. After the X6 gained some decent momentum in the market, the brand launched the X4 back in 2014 and the vehicle was widely accepted as the coupe iteration of the highly popular X3 SUV. Like other vehicles from the brand, the X4 also received the M treatment and it offered some overwhelming performance stats for an SUV of its size.

2021 BMW X4 M SUV Engine and Performance

7.0/10

The 2021 BMW X4 M is powered by an S58 3.0-liter twin-turbocharged I-6 motor. The powertrain has been extensively tuned by M to deliver superior performance as compared to the turbocharged V6 and V8s of the rivals. The motor puts out an impressive 473 horsepower and 442 lb-ft of maximum torque. The twin-turbocharging tech takes care of the turbo lag almost perfectly and it results in sharp acceleration without any hesitation. The motor allows the SUV to even beat the BMW M3 sedan with a 0-60mph time of 4.1 seconds along with a standing quarter-mile time of 12.6 seconds. The motor is mated to a standard 8-speed ZF 8HP automatic transmission and it does a brilliant job of managing all the power on tap and delivering them effectively to all four wheels via a standard AWD layout.

The Alfa Romeo Stelvio Quadrifoglio gets a 2.9-liter twin-turbo V6 under its hood and it is a Ferrari-derived powertrain. Hence, the motor offers a more brutal performance and one of the highest power outputs in the segment. Moreover, the Stelvio Quadrifoglio has a sub-4 seconds acceleration time of 3.6-second, making it practically quicker than some full-fledged sports cars out there. The Mercedes-Benz AMG GLC 63 Coupe is another potent rival of the X4 M and it packs in one of the biggest powertrains in the segment, a 4.0-liter twin-turbo V8. Since it is an AMG-treated vehicle, the SUV proves to be quite outlandish in the way it delivers all that performance and has a 3.8-second 0-60mph sprint time. The Porsche Macan Turbo feels like the most underpowered and the slowest-accelerating vehicle amidst the outright crazy rivals here yet it is no slouch. It also gets a 2.9-liter twin-turbo V6 and has a marginally higher top speed than the X4 M.

How well does the 2021 BMW X4 M handle?

Sharp and precise handling is one of the BMW X4 M’s forte and it’s way better than the already sporty regular X4. The stiffer suspension setup gets an adaptive function yet it remains stiff to offer aggressive and sharp handling at all times. Out on the highways and over smooth tarmacs, the SUV remains poised but the ride deteriorates over bad patches of road, something you wouldn’t expect from a vehicle carrying a price tag of over seventy grand. 

The steering is precise and has enough feel and feedback for a truly engaging drive. The gripe levels from the tires are splendid and allow the SUV to take corners like a piece of cake. The standard AWD layout further enhances the experience with excellent traction that can come in handy over challenging tarmac conditions.

2021 BMW X4 M Braking Performance

The 2021 BMW X4 M gets an upgraded set of brakes over the regular X4 and receives that special treatment from M as well. The front rotors measure at a sizable 15.6-inches while the rear rotors measure at 14.6-inches, making them the biggest one among the competition here. The rotors are cross-drilled to allow internal ventilation for rapid cooling to retain its performance even under stress.

The Alfa Romeo Stelvio Quadrifoglio has much smaller front and rear brake rotors than the X4 M yet its light curb weight helps it to achieve some superb braking prowess. The SUV comes to a halt from 60mph within 103 ft. The Mercedes-Benz AMG GLC 63 has almost similar-sized brake rotors to the X4 M and it weighs close to the latter too. Hence its braking performance is also quite similar to that of the X4 M as well. The Porsche Macan Turbo takes the middle ground here with the brake rotors measuring close to the Quadrifoglio. Yet, it weighs slightly more than the Stelvio hence its stopping distance is expected to be quite similar as well. 

2021 BMW X4 M SUV Fuel Economy

4.0/10

Given the exhilarating power and performance of the SUVs in the segment, it would be quite wrong to judge them in terms of fuel economy figures. The 2021 BMW X4 M can be considered a gas-guzzler when compared to its rivals in the segment. It returns a meager 14mpg of city mileage, 19mpg of highway mileage, and an abysmal 16mpg of combined mileage. Moreover, the SUV comes with a rather small 17.2-gallon gasoline tank, resulting in some sub-par driving range figures. It averages 241 miles in the city and 327 miles on the highway, which is lower than all of its competitors.

The Alfa Romeo Stelvio surprises with its fuel-efficiency numbers as compared to the X4 M and it’s truly impressive since it is the only one here to push out over 500 horsepower and posts a sub-4 second 0-60mph sprint time. However, it disappoints with its below-average gas tank size of 16.9 gallons only. The Mercedes-Benz AMG GLC 63 has marginally better gas mileage ratings than the X4 M and it’s quite acceptable considering the performance it provides. The Porsche Macan Turbo has almost similar mileage rating numbers to the Stelvio but the impressive part about this SUV is its sizable 21.7 gallons gas tank.

2021 BMW X4 M SUV Interior

6.0/10

The 2021 BMW X4 M interior is a nice place to be in and the overall design is quite identical to the more practical X3 SUV. Inside the cabin, there are some subtle yet tasteful M treatments such as the stitches on the seat headrests and M badges placed on the steering wheel, gear selector, and the center console. Other than that, the features and equipment are quite similar to the base X4. Some of the standard features such as heated and electronically adjustable front seats, panoramic sunroof, and tri-zone automatic climate control enhance the comfort levels within the cabin but the stiff ride quality hinders the experience to a great extent.

The Alfa Romeo Stelvio Quadrifoglio has a heavily driver-focused cabin along with sportier interior trims and designs as compared to the regular Stelvio SUV. Like the X4 M, the Stelvio Quadrifoglio is quite comfortable on the inside yet the stiff ride quality hampers the overall experience for the sake of handling. The Mercedes-Benz AMG GLC 63 interior gets a perfect balance of sportiness and elegance with a decent amount of carbon fiber inserts and an abundance of AMG branding. The cabin gets a long list of features and is quite a plush place to be in. However, the coupe roof design limits the overall headroom for the front passengers and even more for the rear passengers as well.

Some of the standout interior features include:

  • Tri-zone automatic climate control
  • Heated and electronically adjustable front seats
  • Full leather upholstery
  • Heated steering wheel(optional)
  • 40-20-40 Folding Bench Rear Seats
  • Interior Air Filtration

What’s there to keep you entertained?

BMW provides one of the best infotainment systems in the market in the form of the iDrive system and it finds its way in a majority of the vehicles from the brand. The 2021 BMW X4 M gets the latest iDrive 7 interface that runs on a big 10.25-inch touchscreen display. In terms of features, the system is quite loaded and offers some standard ones such as Apple CarPlay, Sirius XM satellite radio with a 1-year subscription, BMW ConnectedDrive services, and Android Auto.

Some of the standout infotainment features are:

  • 10.24-inch touchscreen display with iDrive 7 interface
  • Apple CarPlay and Android Auto
  • Sirius XM radio
  • BMW Connected car services
  • 16-speaker Harman Kardon sound system
  • Gesture controls(optional)

2021 BMW X4 M SUV Exterior

9.0/10

The 2021 BMW X4 M exterior is almost identical to the regular X4 with some subtle differences in terms of body kit and styling. The front fascia gets the iconic kidney grilles with a small M badge while the aggressive air dams along with the LED headlamp units with the LED running lights make for a pleasant theme upfront. The wheels are big 20-inch units with an M-specific design while the side profile remains simple. The rear end looks nothing different apart from the M badging and the coupe-style roof gives the vehicle plenty of character. The ground clearance is quite practical at 8.1-inches.

The Alfa Romeo Stelvio Quadrifoglio gets the most polarizing yet classic Italian styling, especially at the front. The huge headlamp units do justice to the angry-looking front grille design while the side profile of the SUV remains quite simple barring the unique wheels. The Mercedes-Benz AMG GLC 63 Coupe gets that frowning front grille design that made its debut with the AMG GT and combined with the coupe roof design, it gives off a mixed bag appearance to the SUV. It also rides the lowest to the ground with a ground clearance of 6.4-inch, making it quite impractical as an SUV. The Porsche Macan Turbo has a proper aggressive front-end design, a rarity among the vehicles from the brand and it suits the SUV’s performance stats perfectly. Its practicality as an SUV is limited too, like the AMG GLC 63, yet its overall design makes it more sane and desirable over the latter.

Some of the standard exterior features include:

  • Sunroof with express-open and close function
  • Lip spoiler
  • 20-inch M wheels
  • Power liftgate
  • LED headlamps with auto high beams
  • Perimeter lights

2021 BMW X4 M SUV Safety

8.6/10

The 2021 BMW X4 M has not been crash-tested by both the IIHS and the NHTSA owing to its low sales volume. But the 2021 X3, on which the SUV is based, received some splendid safety scores, a perfect 5-star from the NHTSA, and an overall “Good” rating from the IIHS. Apart from that, the SUV gets some handsome driver assistance features such as Forward collision mitigation, Blind-spot monitor, and Lane departure warning. 

Some of the notable safety features are:

  • Traffic Light Recognition System
  • Smart Cruise Assist
  • Active Lane Assist
  • Automatic Braking System
  • Lane Departure Warning with Lane Keep Assist
  • BMW Active Driving Assistant

2021 BMW X4 M SUV Competition

7.9/10

2021 BMW X4 M vs. 2021 Alfa Romeo Stelvio Quadrifoglio

The Alfa Romeo Stelvio Quadrifoglio gives the X4 M a run for its money with its car-like handling and a sub-4 second 0-60mph sprint time. Moreover, the Stelvio is more fuel-efficient than the X4 M which might come as a surprise. The Stelvio also handles slightly better than the X4 yet the latter triumphs over the former with more interior features and comfort levels. However, both the X4 M and the Stelvio Quadrifoglio even out in terms of ride quality and practicality.

2021 BMW X4 M vs. 2021 Mercedes-AMG GLC 63 Coupe

The Mercedes-Benz AMG GLC 63 Coupe might feel like an overkill owing to its bigger powertrain yet lower power figures than the X4 M, yet it proves to be a slightly more sensible option than the latter. The GLC 63 offers slightly better headroom and legroom for the rear passengers while it falls short in terms of cargo space. The X4 M has better ground clearance, giving it an edge over the AMG GLC 63. 

2021 BMW X4 M vs. 2021 Porsche Macan Turbo 

The Porsche Macan Turbo might be less powerful and exciting than the X4 N, yet its better fuel economy figures and excellent driving range make it more desirable for daily driving. Moreover, the Macan offers a better ride quality but loses out on the practicality aspect due to its lower ground clearance.

2021 BMW X4 M SUV Final Verdict

As a package, the 2021 BMW X4 M is an appealing option in the segment. It has some impressive performance on tap, a nice cabin to live with, and decent ground clearance to take on bad patches of roads. However, the vehicles of this segment are not meant for optimum ride comfort and luxury hence buyers looking for the same might be utterly disappointed. Yet, the SUV shines brightly when it comes to outlandish performance and sportscar-rivaling handling.
