2026 BMW X3 Review: Specs, MPG, Price & Verdict

The 3 Series has always been a hallmark of BMW performance: it brings the best combination of the qualities of a family sedan and a performance car in one car. Because of that, expectations were surely going to be high from any model which intended to use the 3 number, even an SUV.

Fortunately, the X3 has handled this mission very well. Dynamic behavior is agile and engaging without taking a toll on fuel consumption, the cabin is roomy and comfortable while preserving the BMW identity, and the equipment list is satisfactory while leaving any excesses to the larger SUVs.

Rather than an “SUV made by BMW”, the X3 is a “BMW in an SUV shape” – and that means a lot. It means that BMW’s excellence at dynamic behavior has been successfully reinterpreted to suit such a larger and heavier model. The base powertrain brings a well-rounded ride while the M50’s take it to a whole new level.

Engine and gear

The base engine is a turbocharged 2.0-liter four-cylinder with 48-volt mild-hybrid assistance, which makes 255 hp. While it does not bring any intense emotions when driving, it is capable enough for this type of SUV in almost all typical situations. It comes with an eight-speed automatic transmission.

People looking for performance-car power may opt for the M50 version, whose turbocharged, 3.0-liter six-cylinder is good for 393 hp and sprints from 0 to 60 mph in just 4.4 seconds — quick enough to match the likes of Mercedes-AMG GLC 43 and Porsche Macan.

Suspension

Adaptive suspension is an interesting item available in the X3’s options list. The equipment offered for the entry-level 30 xDrive is adaptive damper control and brings the Comfort, Sport, and Eco Pro driving modes.

The M50 version has an adaptive M suspension of its own, which not only brings driving modes as well but also sits lower on a sport-tuned chassis.

Handling

The X3 is widely praised for its driving dynamics; in fact, it has been deemed better than some of BMW’s current sedans despite being an SUV. Whether when cornering or when going on stretches at high speeds, it offers a refined and controlled behavior that makes it actually fun to drive.

Ride & Vibration

All those years of experience with SUVs have made BMW reach a well-balanced behavior on the X3. It offers enough firmness to inspire confidence in the driver without reaching the point of affecting ride comfort. Once again, this model is refined as several of the company’s traditional sedans.

While the X3 shines at the previous topic, it only meets expectations here. However, that is far from a bad thing: even the entry-level 30 xDrive brings a long list of standard items and offers many others as options. The M50 is better equipped, of course, but its differences mostly aim at adapting the car to its exclusive performance-oriented behavior.

Brakes

From the base version, the model offers disc brakes on all wheels along with a series of electronic systems to aid their operation. There are ABS, brake-pad wear indicator, Cornering Control, Dynamic Brake Control, and even Brake Fade compensation. The parking brake is electromechanical.

Airbags

The X3’s standard package includes front and side-protection airbags for the front-row seats. The airbags of the first type come with dual-threshold and dual-stage deployment along with a presence sensor for the front passenger seat to prevent unnecessary deployment.

Electronics

The typical suite of safety electronic aids expected from this type of car comes as standard here, with some items left as optional. Automated emergency braking, forward-collision warning, and lane-departure warning are standard while active cruise control is optional.

Lights

The 2026 BMW X3 brings full adaptive LED headlights even at the base trim level along with adaptive brake lights. The M50 version upgrades the headlights with the automatic high-beam function.

Traction control

This model brings a series of electronic systems focused on improving its driving dynamics. The Dynamic Traction Control comes as standard from the base trim level and is part of the Dynamic Stability Control system. The M50 goes further and adds a Performance Control system.

Thanks to the new 48-volt mild-hybrid system, the EPA ratings now place this model near the top of its class. It also brings the great news that the M50 does not consume so much more fuel than the 30 xDrive: it means that opting for the performance SUV will not bring sports-car mileage.

Engine size

The 30 xDrive uses a turbocharged, 2.0-liter four-cylinder engine good for 255 hp of power and 295 lb-ft of torque. The M50 uses a turbocharged, 3.0-liter six-cylinder unit which increases those figures to 393 hp and 428 lb-ft, respectively.

Gas per mileage consumption

The 2026 BMW X3 30 xDrive makes an excellent 27/33 mpg (city/highway) — top-of-class figures for a gas-powered luxury compact SUV. The M50, in turn, makes 25/30 mpg.

German engineering at its finest. While the design is not surprising at all, everything is made with high quality and attention to detail. The base X3 may not come with fancy materials, but everything was designed tastefully and features tight and consistent gaps.

Driving seat

Nothing to complain about here. Plenty of space between a nicely-trimmed dashboard and front seats which come with several functions as standard. The driver will enjoy 10-way power settings, which include adjustable side bolsters.

Dashboard

The latest redesign brought a bold new cabin, with a flat dashboard dominated by a large curved display and wraparound ambient light bars. Depending on the trim, surfaces mix knit textile and metal-look accents with stitched upholstery that also extends to the door panels.

Passenger seats and extras

While the front passenger boasts the same power adjustments on its seat as the driver, the rear ones will enjoy reclining seats cushioned in a way to be ergonomic even during long trips. Standard upholstery is now Veganza, BMW’s synthetic leather, while upscale builds can opt for genuine Merino leather.

Overall height and space

The car’s overall height is 65.4 inches, and the new generation is longer and wider than before. It offers a roomy five-seat cabin, which makes EPA classify it as a small sport utility vehicle.

Trunk space

The 2026 BMW X3 offers 31.5 ft³ of cargo volume, expanding to 67.1 ft³ with the second row folded. That is more space than most rivals, including the Genesis GV70 and Porsche Macan.

Nothing impressive here. Base trims come at average prices while the sporty one charges a hefty extra for its more vigorous performance. The lineup will have more options soon, as mentioned below, but both are expected to be on the expensive side of the spectrum.

For now, these are the only two versions offered in the US; an even sportier full X3 M is rumored to join later in this generation.

AWD/RWD

Every 2026 X3 comes standard with xDrive all-wheel drive — the rear-wheel-drive sDrive version was dropped with the latest redesign.

Warranty

This model offers limited warranty coverage of four years or 50,000 miles, whichever expires first. Besides, BMW offers complimentary scheduled maintenance during the first three years or 36,000 miles. Both services place the X3 at an average position in its category.
