2025 BMW X3: What We Know So Far (2024)

Overview

The BMW X3 helped kickstart the compact luxury crossover segment when it debuted back in 2004 and went on to become the maker’s best-selling model. The new, fourth-gen 2025 X3 builds on that solid record of success with incremental updates and improvements that refine the breed rather than reinvent it. All-wheel drive is standard for 2025, and the performance-focused M40i is replaced by the M50. (Notably, BMW drops the "i" from the model names of its gas-powered vehicles going forward, reserving the letter for use exclusively on its EVs.) Our drive of 2025 X3 prototypes revealed the new X3 is larger in every exterior dimension, yet it possesses a lower drag coefficient than the outgoing model, thanks to the newly styled yet more aerodynamic bodywork. BMW cautiously mixes in fresh tech as well, including more audio and video streaming services as well as some gaming options for fun when parked. The four and inline-six-cylinder powertrains return, but both get a mild hybrid component and a small increase in output. The fully electric iX3 will arrive later built on an entirely different platform and will exist alongside the new X3. A plug-in hybrid isn’t yet confirmed for the American market, but we'd be surprised if it doesn't join the lineup given America's renewed interest in hybrids of all stripes. What doesn’t change is the X3’s tasteful luxury appointments, refined ride-handling balance, and its position as a stylish, right-sized compact crossover in one of the hottest segments.

What's New for 2025?

Almost everything. Larger overall, the fourth generation 2025 X3 benefits from a revised exterior design and chassis, tweaked powertrains, and updated infotainment and driver-assist features. Notably, all-wheel drive is now standard, eliminating the sDrive trim, and the M50 replaces the previous M40i. With BMW dropping the "i" from the model names of its gas-powered vehicles, reserving the letter for use exclusively on its EVs, the 2025 models are known as the X3 30 xDrive and the X3 M50. The 2025 X3’s driver-assist systems add a bunch of new comfort- and safety-enhancing tricks including automated lane change, adaptive cruise control with traffic-light recognition, and parking assistant. There’s also a new available Parking Assistant Professional Package that lets the car park itself in a predesignated parking space that's been saved in the vehicle's computers—think your assigned spot in a parking lot or garage—even while you are outside of the vehicle.

Pricing and Which One to Buy

Considering the nearly $15k gap, we think the 30 xDrive represents the best value. Yes, the 2025 M50's 393-hp inline-six ensures a more genuine BMW experience, and for some drivers, the $65,275 price tag is just the cost of doing BMW business. Of course, the inevitable 2025 X3 M performance variant might offer a better horsepower-to-dollar ratio.

Engine, Transmission, and Performance

The turbocharged 2.0-liter four-cylinder in the 30 xDrive is boosted by a 48-volt hybrid system and makes 255 horsepower. The M50 is the real performer though, as its turbocharged 3.0-liter inline-six gets the same hybridization system and a 393-hp rating. Both employ an eight-speed automatic transmission and all-wheel drive. We were able to sample prototypes of the 2025 X3 and found that it builds on the previous-generation model's already good road manners with a stiffer body structure and revised suspension. We’re confident that the changes will sharpen responses while leaving its ride quality unsullied. Speaking of which, an adaptive suspension is standard on the M50 and can be ordered as an option on the 30 xDrive. Three drive modes, Personal, Efficient, and Sport, are provided to tailor responses to the driver's needs. An optional trailer hitch allows the X3 to tow up to 4850 pounds.

0–60-MPH Times

While we haven't tested the 2025 X3 yet, BMW is claiming a 6.0-second 60-mph-time for the new model. That should help the X3 narrow the gap between it and the Porsche Macan S and the Audi Q5. The X3 M50's 393 horsepower should put it within a tenth or two of the outgoing M40i's 4.1-second time. Top speed for the 30 xDrive is 130 mph; the xDrive M50 tops out at 155 mph when equipped with the performance tires.

Fuel Economy and Real-World MPG

The EPA hasn't released official fuel economy numbers for the 2025 X3 yet, but we're hoping the hybridization and engine tweaks will improve on the previous 2024 X3's only so-so numbers. Specifically, the previous base rear-wheel drive model was rated for 23 mpg city and 29 mpg highway while the outgoing M40i was at 21 and 26 in the same measures. Interestingly, both outperformed their EPA estimates in our 200-mile real-world highway test, returning 31 and 29 MPG respectively.

Interior, Comfort, and Cargo

Standard equipment includes new heated and ventilated power-adjustable sport seats with three available color choices for the faux-leather upholstery. There's also an optional faux leather and faux suede combination available, as well as genuine leather. A woven fabric instrument panel made from recycled polyester is also on offer, marking its first use on any BMW product.

Infotainment and Connectivity

BMW's latest iDrive 9 infotainment system makes its X3 debut, and the iDrive rotary knob remains in place—a nice surprise considering its conspicuous absence on the recently refreshed X1 and X2 models. The system also accepts inputs via the touchscreen, steering wheel controls, and voice commands. A head-up display is optional. BMW Digital Premium allows for video streaming and gaming options when the vehicle is stopped, the latter in single- or dual-player modes. Spotify and Amazon Music join the X3's list of audio streaming services.

Safety and Driver-Assistance Features

A full suite of driver-assistance features is available, but BMW offers the basics as standard equipment. For more information about the X3's crash test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:

• Standard automated emergency braking with forward-collision warning
• Standard lane-departure warning
• Available adaptive cruise control

Warranty and Maintenance Coverage

BMW’s warranty offerings on the current X3 don’t stand out among its rivals; its four-year or 50,000-mile basic warranty is common in this segment. Three years of complimentary scheduled maintenance is nice, but it’s something that the Genesis GV70 and the Volvo XC60 also offer.

• Limited warranty covers 4 years or 50,000 miles
• Powertrain warranty covers 4 years or 50,000 miles
• Complimentary scheduled maintenance covered for 3 years or 36,000 miles
