2026 BMW X3 Engines and Powertrain Options

Both 2026 X3 engines use 48-volt mild-hybrid assistance for smoother stop-start and a small efficiency gain, and both send power through an eight-speed automatic to standard xDrive all-wheel drive. The split is straightforward: a four-cylinder for efficient daily driving, an inline-six for performance.

X3 30 xDrive

The 30 xDrive runs a turbocharged 2.0-liter four-cylinder rated at 255 horsepower and 295 lb-ft of torque, reaching 60 mph in about 6.0 seconds (BMW preliminary). It returns an EPA-estimated 29 mpg combined, which makes it the efficient, everyday choice for highway miles and around-town errands.

X3 M50 xDrive

The M50 xDrive upgrades to a turbocharged 3.0-liter inline-six producing 393 horsepower and 428 lb-ft of torque, with a 0-60 mph time of roughly 4.4 seconds (BMW preliminary) and an EPA-estimated 27 mpg combined. Standard on the M50 xDrive: Adaptive M Suspension, M Sport brakes, an M Sport differential, and a quad exhaust, giving it sharper reflexes and a firmer tune than the 30 xDrive.

X3 Trim Lineup and Pricing

The lineup is two trims, and the choice is really about powertrain and intent.

X3 30 xDrive — the efficient default

Starting in the low $50,000s, the 30 xDrive delivers the core X3 experience: the curved display, the standard driver-assist suite shared across the lineup, AWD traction, and a refined four-cylinder. Many shoppers find it more than enough, and it is easy to option without crossing into M50 money.

X3 M50 xDrive — the performance pick

Starting in the mid $60,000s, the M50 xDrive adds the inline-six, M Performance chassis tuning, and M styling cues for drivers who want sports-sedan pace in an SUV body.

MSRP excludes destination, taxes, and fees; figures vary with options and current incentives, so confirm current pricing with the dealership. Exact per-trim MSRP is broken out on the trims compared and specs pages.

Technology and Connectivity

The 30 xDrive and M50 xDrive share a 14.9-inch BMW Curved Display paired with a 12.3-inch digital instrument cluster, running BMW Operating System 9 (iDrive 9) as standard across the lineup. That software arrived with the fourth-generation X3 redesign, which was introduced for the 2025 model year and carries into 2026, replacing the prior iDrive 8 interface and reorganizing the home screen around widgets. The interface supports touch, voice, steering-wheel controls, and a rotary controller, and the BMW Interaction Bar adds ambient lighting and quick-access controls across the dash. BMW Digital Premium is available as a subscription for streaming and in-vehicle apps, and a Head-Up Display is available.

Interior and Comfort

Inside, the X3 takes a clean, minimalist approach with standard front sport seats on the 30 xDrive and M50 xDrive, a choice of Veganza and leather upholstery, and available Ambient Lighting offering 15 colors. The cabin seats five, with room for three across a comfortable rear bench. For dimensions, upholstery options, and cargo figures, see the cargo space page.

Cargo and Passenger Space

The X3 balances a compact footprint with a usefully flexible cargo area, and the rear seats fold to expand it for road-trip gear or a weekend's worth of equipment. Available towing capability, when properly equipped, adds practical utility for light trailers. Exact cargo volumes and the towing figure are detailed on the cargo space and specs pages.

Safety and Driver Assistance

On the 30 xDrive and M50 xDrive alike, the Active Driving Assistant suite is standard, bundling Frontal Collision Warning, Lane Departure Warning, and Active Blind Spot Detection. A rear camera and Brake Assist support everyday confidence, and Driving Assistance Plus is available for hands-on assisted driving with adaptive cruise and steering support. For a full feature breakdown, the specs page breaks down standard and available equipment by trim.

Which 2026 BMW X3 Is Right for You?

Around here, much of the driving is dry-pavement freeway commuting with the occasional climb into the Coast Range or a weekend run toward the mountains, where standard xDrive all-wheel drive adds traction without anyone needing a dedicated off-roader. Use this quick router to match an X3 to how you actually drive.
