The 2021 BMW X4 is a more voguish version of the X3 SUV, exchanging function for style. This could be the vehicle for you if you are engaged in trading some pragmatism for added style. The BMW X4 starts at $52,000 for the base trim and goes up to $62,000 for the M performance trim.

The X4 xDrive30i uses a 2.0-litre four-cylinder rated at 248 horsepower and 258 lb-ft of torque. It's suitably robust, but the M40i gets a 3.0-litre six-cylinder good for 382 hp and 365 lb-ft, a more fitting choice for the X4's sporting character. It gets superb handling and an upscale cabin with user-friendly features, but it trails the competition in terms of interior space.

Overall Rating

The shift in priorities from sporty luxury sedans to sporty luxury crossovers for BMW is complete; the 2021 X4 is proof. BMW buffs and brand patriots may find that hard to swallow, but at least the X4 has a sleek shape to help the medicine go down smoother. 

For the upcoming year, it remains the same coupe-shaped SUV, which may not necessarily be high on practicality but is athletic for sure. The competitors of the 2021 X4 include Jaguar F-Pace, Audi Q5, and the Mercedes Benz GLC-Class Coupe

2021 BMW X4 Features


The 2021 BMW X4 is available in two trims; xDrive30i and M40i. Apart from standard and safety equipment, both trims have turbocharged engines, all-wheel-drive, and 8-speed automatic transmission. The M40i is just a sportier version of the base X4 with some hardware upgrades outside and under the hood.

Standard safety features include a rearview camera, front and rear parking sensors, forward collision warning, pedestrian detection, automatic emergency braking, LED headlights, and rain-sensing windshield wipers.

Trim xDrive30i
MSRP $51,600 (exp.)
Key 19-inch wheels

  LED headlights
  10.3-inch touchscreen
  A navigation system

The entry-level X4 xDrive30i has a starting MSRP of $52,000. It comes with a 248-horsepower turbocharged four-cylinder engine, an eight-speed automatic transmission, and all-wheel drive. Standard convenience features include the iDrive infotainment system with a 10.2-inch touch screen, navigation, Apple CarPlay, Bluetooth, two USB ports, a 12-speaker stereo, HD Radio, a 12.3-inch digital instrument cluster, and automatic climate control.

The X4 M40i model starts at $62,000, and it packs a 382-horsepower turbocharged six-cylinder engine. This trim adds 14-way power-adjustable front seats and adaptive LED headlights, plus the contents of the Dynamic Handling package.

2021 BMW X4 Maintenance, Reliability and Warranty

The current generation BMW X4 is not among the most reliable SUVs out there. BMW has always enjoyed a desirable reputation, but this is built on the brand's association with sporty driving manners, excellent residual values, and an aspirational image than an especially keen owner satisfaction record. According to the federal authorities, which you will see in just a bit, the BMW X4 has been a car full of problems in this current generation.

Reliability and Ownership Costs

The 2020 BMW X4 xDrive30i received an overall 85 out of 100 that makes it the highest-rated car in its segment. There is a slight dip in the ratings in the resale category with receiving a score of 74 out of 100. According to NHTSA, the 2nd generation X4 has had six different recalls, as listed below.

  • Fractured rod affects the handling of a vehicle and can even result in a crash.
  • Improper deployment of airbags
  • An airbag deployment could cause damage to the instrument panel hence increasing the risk of injury
  • Loss of steering control increases the risk of a crash
  • Lack of an image in the back-up camera display
  • Broken swivel bearings could cause loss of vehicle control

Most people would want to avoid considering the car has had six recalls, and it's not even two whole years since the first recall was done. It remains to be seen how well BMW has ironed out any potential issues for the 2021 model year, and enthusiasts would surely want BMW to have more focus on the quality of their product now. 

The average annual repair cost for a BMW is $968, which means it has average ownership costs. The other factors contributing to BMW reliability include an average of 0.9 visits to a repair shop per year and a 15% probability of a severe repair. If you buy the 2020 X4, the following will be the costs that will be incurred in a span of 5-years from the date of purchase:


Year 1

Year 2

Year 3

Year 4

Year 5























Taxes & Fees




























Real Cost of Ownership







The base price is among the highest in the luxury SUV segment. And the price soars even more if you choose the more upper trim. On average, X4 is priced around 48,000USD, which is 3,000 USD less than the MSRP. The cost of ownership for X4 spread over five years is around 67,989USD.

While the prices seem to be the highest in Michigan, they will be the lowest in Montana, Delaware, Oregon, Alaska, and New Hampshire due to the exemption of sales taxes levied on automobiles.


The coverage that BMW has is excellent compared to what its non-mainstream rivals have to offer.. But the talking point is the Complimentary scheduled maintenance, which can be described as a feather to its cap considering that isn’t what its rivals can offer.

BMW offers four years or 50,000 miles (whichever comes first) bumper to bumper warranty. Unlike other manufacturers offering two different warranties covering basic and powertrain separately, BMW provides an original warranty covering both. 



Limited warranty

4 yr./ 50000 miles; whichever is earlier

Powertrain warranty

4 yr./ 50000 miles; whichever is earlier

24-hour roadside assistance

4 yr./ unlimited miles; whichever is earlier

The automaker also offers a Corrosion warranty that covers damage to sheet metal due to corrosion or rust. For cars manufactured in or after 2004, it lasts 12 years or unlimited miles. For vehicles made in 2003 or earlier, it lasts for six years or unlimited miles.

There is also a wear and tear warranty, in which BMW covers specific wear or tear parts if the damage is due to material or manufacturing defect.

Miles Per Dollar

For every mile you’ll make in your X4, you’ll be shelling out $7. This price is still favourable compared with the American rivals when they’re equipped to the same levels.

2021 BMW X4 Buying Advice

We think most buyers who have already come to embrace the X4 compromises will prefer the performance of the M40i version. Its turbocharged inline-six fulfills the promise made by the X4's shapely body, and it is undeniably more rewarding to drive than the base xDrive30i trim.

We suggest sticking with the base model X4 xDrive30i, especially if you can’t afford to stretch your budget. This model should provide enough thrills for most shoppers. It’s also well-equipped with standard features.

Is buying a used car BMW X4 a good idea?

BMW redesigned the X4 for the 2019 model year. There are not many changes apart from that in the SUV. The X4 carries over relatively unchanged. If you’re only interested in the standard model, you can save money by shopping for a 2019 X4, and you’ll get similar performance and features as a new X4.

Be wary of the recalls mentioned above and check the records if the car has been inspected thoroughly, and there were quite a few of them. You can potentially save even more money by shopping for a previous-generation X4, which covers the 2015 to 2018 model years, but you’ll have to make a few concessions

2021 BMW X4 Engine and Performance


BMW has already put their best powertrains in the X4, so they have no intention to fiddle with that. The xDrive30i comes with a turbocharged 2.0-liter four-cylinder offering 248 hp and 258 lb-ft of torque. Despite its small size, the 30i engine feels almost as quick and eager in day-to-day driving. The eight-speed automatic transmission serves up quick, smooth shifts as well.

The more fun version M40i uses a turbocharged 6-cylinder engine, which puts out 382 hp and 365 lb-ft of torque—the M40i’s all-wheel-drive system biases more power toward the rear, which helps the crossover feel sportier.

Regardless of which X4 you choose, you'll be treated to an SUV that matches sharp handling with a ride quality that's easy to live with.

All the cars are almost evenly matched with the power and torque figures though the X4 lags a little behind with its torque output. Mercedes comes off as the most powerful and efficient of the lot, and it offers a class-leading 9-speed automatic transmission.

2021 BMW X4 Acceleration And Braking Performance

The car doesn't just sprint off the line as we some handful of sport SUVs do nowadays, but there is plenty of grunt on offer the moment you get going from a standstill—the base xDrive30i  sprint from zero to 60 mph in a respectable 6.0 seconds. BMW's X4 M40i hustles from zero to 60 mph in a scant 4.2 seconds, and its engine note is as impressive as its acceleration. Launch control also comes as standard.

The brakes in the X4 are smooth and easy to operate in everyday conditions. The car is weighted well, so it inspires a lot of confidence in the corners. The steering and brakes both come together to give sharp and accurate feedback to conquer the twisties faster than you thought you could handle.

The Audi Q5 is the quickest of the lot thanks to its efficient dual-clutch and Quattro AWD tech. Macan is the slowest among the competition, while X4 takes the middle ground, followed by the Mercedes-Benz GLC-Class.

2021 BMW X4 Fuel Economy


The X4 xDrive30i gets an EPA-rated 23 mpg in the city and 28 mpg on the highway. These are some of the best fuel economy ratings in the luxury compact SUV class. The X4 M40i model gets a respectable 21 mpg in the city and 27 mpg on the highway.

The BMW X4 has the best range in its competition, all courtesy to its best in class mpg figures despite all the others having bigger fuel tanks. The Audi Q5 posts the lowest fuel economy and low range due to its smaller fuel tank.

2021 BMW X4 Interior


The interior of the 2021 X4 might be a bit more vanilla and watered down than the exterior, but it is still attractive in its way. The design language of the cabin is clean and quite modern. Trim pieces are made of quality materials, including soft-touch plastic, aluminum, and synthetic leather are strewn across the cabin to give it a little more upmarket feel than it is. The cabin is also really well insulated from any outside noise.

2021 BMW X4 SUV seating layout

Getting into the rear row is a bit tricky as you might bump your head into the swooping roofline if you are not careful. But once you get seated, it is a roomy place to be in with acres of legroom on offer, although some rivals have more. The front seats are more than comfortable for even taller people; their shape is comfortable and supportive. The seats have a great deal of adjustability with thigh extenders and inflatable side bolsters; they make a great place to be during longer stints on the road.

All cars have almost similar dimensions on paper, but in reality, it is the Q5, which is the roomiest. Mercedes offers the smallest interior dimensions in the front row owing to its sloping roofline. This BMW has 18.5 cubic feet of cargo space with its rear seats upright and 50.5 cubic feet with these seats folded down.

How’s the 2021 BMW X4’s infotainment system?

Significant changes have been made in this area for the 2021 model year. The dashboard is completely redefined and looks a lot thinner than before, there is a new dash-top infotainment screen, and overall the whole aesthetic of the upper dash includes many angular lines and shapes. The center stack looks wholly modernized, and an all-new steering wheel and center console sit in front.

BMW also offers plenty of entertainment features inside the cabin, all controlled by a 10.3-inch infotainment screen apart from the 12.3-inch instrument cluster. The iDrive 7.0 system accepts multiple inputs like voice, touchscreen, and iDrive touchpad Controller. Gestures also work great, and they are not as distracting as it was the case before. Here are some of the standard equipment in the 2021 X4

  • iDrive Infotainment System
  • Dual Zone Climate Control
  • Heated Seats
  • HiFi Sound System with 12-speakers and a 205-watt digital amplifier
  • Eight Way Power front seats with memory functions
  • Anti-theft AM/FM stereo with Radio Data System
  • Apple CarPlay Compatibility (now as standard)
  • Bluetooth wireless communication for hands-free mobile phone

Compared to the related X3, the X4 has a tapered roofline that slopes toward the rear liftgate more dramatically than a classic whodunit. Both models get the same 19-inch alloy wheels, although each is styled differently. The xDrive30i comes with LED headlights, taillights, daytime running lights, and fog lights, while the more expensive M40i gets adaptive full LED head- and tail lights.

The sleek coupe-like roofline gives it a distinct silhouette as it houses the panoramic moonroof. The dimensions have been fiddled with just a little bit so that the passengers at the rear have a bit more legroom than before.

The dimensions of the X4 have been increased to increase the room for the rear row, and as a result, it is comparatively bigger and heavier than the rest of the cars. Macan comes off the smallest vehicle of the lot, which is the reason for its sporty and agile handling.

2021 BMW X4 Safety


The 2020 BMW X4 hasn't yet been crash-tested by the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS). There are many optional driver-assistance features available, but the list of standard amenities in this area is meager.

2021 BMW X4 Competition


2021 BMW X4 Vs. Porsche Macan

Both the cars mentioned here are outstanding performance and sporty SUVs. Muscular engines, crisp acceleration, sharp handling, and standard all-wheel-drive; inside are quality materials and crisp styling on both these SUVs.

2021 Porsche Macan

Even the pricing is similar, both are costlier than your average luxury SUV, but both of them offer that solid German engineering. Life is hard, isn’t it, and so are the choices we make.

2021 BMW X4 Vs. Audi Q5

Fortunately, the Q5 has a different flavour in the way it drives; the engine is zestily coupled with agile handling. The interiors are lovely, too, with seats that are comfortable to be in.

2021 Audi Q5

Audi’s reputation for in-car tech shows here with the intuitive infotainment screen doing the duties, but the Q5 has more back-seat space and cargo than the X4, so the practicality is more. Furthering this point is that the starting price of the Q5 is a whole lot less, thousands to be precise than the X4.

2021 BMW X4 Final Verdict

The 2021 BMW X4 is the perfect example of a luxury compact SUV with crisp interiors and comfortable seats. It is also brilliant and fun to drive due to its composed handling. The suspension is also capable of handling almost all bumps thrown its way, and the 4-cylinder has some of the best fuel economy figures in the segment. Should you buy it or not requires some thought as this SUV is not for everyone. Yes, safety is significant, but the car also costs more for a slightly less practical SUV if compared. If practicality is a top priority and the pros of the X4 don’t convince you, you are better off looking elsewhere.
