2026 BMW X3 Extended Specs, Engine, Review – BMW is gearing up to redefine midsize luxury SUVs with the all-new 2026 BMW X3 Extended. This latest generation brings an elongated wheelbase and stretched proportions that are more than just cosmetic—they’re engineered for comfort and presence. Compared to the outgoing X3, the 2026 Extended model features a 4.3-inch longer body, optimizing both rear-seat space and cargo capacity without compromising BMW’s hallmark proportions. The updated design is underpinned by the modular CLAR platform, now optimized for hybrid and electric integration alongside combustion engines. 2026 BMW X3 Extended Specs
2026 BMW X3 Extended Redesign and Update Plan
Exterior & Interior
From the outside, the 2026 BMW X3 Extended exudes refinement without losing its athletic BMW essence. The longer rear overhang is seamlessly integrated into the silhouette, allowing for a harmonious blend of design and space. Standard 19-inch wheels are newly designed, while higher trims offer optional 21-inch performance rims. BMW also debuts a new range of metallic paint finishes like “Frozen Bronze,” “Mineral Red,” and “Skyline Graphite,” giving the SUV a high-end, modern appeal. Roof rails and chrome window trim add functional luxury, while aerodynamic sculpting reduces wind resistance for better efficiency.
The interior is where the Extended badge earns its name. Rear-seat occupants are the true beneficiaries, with more legroom, wider door openings, and adjustable seat recline that turn the second row into a premium lounge. The cabin layout is minimalist yet high-tech, anchored by a massive 14.9-inch curved display with integrated 12.3-inch digital gauge cluster. Soft-touch vegan leather surfaces, genuine aluminum inlays, and customizable ambient lighting create a welcoming yet futuristic feel. The rear cargo area now exceeds 31.2 cubic feet, expandable to over 65 cubic feet with the seats folded.
BMW’s focus on comfort and acoustics shows in the use of dual-pane laminated glass, added cabin insulation, and vibration-dampening subframes. Tri-zone automatic climate control, power rear sunshades, and massage functionality for the front seats are all available. The redesigned gear selector has been downsized to a minimalist toggle integrated into the center console, freeing up space for storage and wireless device charging pads. Cup holders are now heated and cooled—an extra touch of refinement you won’t find in competitors.
The exterior receives a bolder identity, aligning the X3 Extended more closely with the X5 in terms of design language. The front fascia now showcases slimmer matrix LED headlamps, a vertically stacked kidney grille with active shutters, and a sculpted hood that adds visual tension. Side profiles are sleeker with pronounced shoulder lines, flush door handles, and aerodynamic side mirrors. The extended rear doors subtly hint at the added legroom inside, while the tailgate boasts new L-shaped LED clusters with integrated dynamic indicators.
This model also introduces the iDrive 9 ecosystem across the entire trim range, with over-the-air (OTA) software support for continuous improvement. The infotainment system is smarter and faster, with a redesigned interface that supports touch, voice, and gesture commands more intuitively than ever before. BMW’s digital key functionality has been upgraded to work with Apple and Android ecosystems, and users can now share access to the vehicle remotely with encrypted, temporary digital keys.

Engine & Performance
Under the hood, the 2026 BMW X3 Extended offers a diverse powertrain lineup, catering to all driving preferences. The base xDrive30i uses a turbocharged 2.0-liter inline-4 producing 255 hp and 295 lb-ft of torque—enough for a 0-60 mph time of 6.1 seconds. This engine is now coupled with a 48-volt mild hybrid system for smoother idle-stop transitions and better fuel economy. The all-wheel-drive system has been recalibrated for quicker torque distribution and improved off-road capability.
The xDrive40e plug-in hybrid variant returns with an upgraded 2.0-liter engine paired with a 135 kW electric motor, generating a combined 375 hp and 406 lb-ft. BMW claims an electric-only range of up to 52 miles thanks to the new 22.1 kWh battery, making it more usable for daily commutes. It supports both AC charging at 11 kW and DC fast charging up to 50 kW—rare in the PHEV segment. Driving dynamics are more engaging too, thanks to adaptive M suspension and revised steering geometry.
For enthusiasts, BMW will offer the X3 M50 xDrive, powered by a turbocharged 3.0-liter inline-6 with 48V support, delivering 420 hp and 443 lb-ft. This variant completes the 0–60 sprint in just 4.4 seconds and includes performance enhancements like M Sport brakes, variable sport steering, and a rear-biased AWD system. Engine noise is digitally tuned via BMW’s IconicSounds system, giving drivers full control over the auditory experience inside the cabin. 2026 BMW X3 Extended Specs
2026 BMW X3 Extended Fuel Economy
Fuel economy sees meaningful improvements across the board thanks to mild hybridization and weight optimization. The base xDrive30i now returns up to 29 mpg combined, while the xDrive40e plug-in hybrid boasts a total range of 530 miles (combined gas and EV). The hybrid also delivers up to 89 MPGe in electric mode, making it one of the most efficient SUVs in its class. Regenerative braking settings can be adjusted via the infotainment system, and the hybrid powertrain has a new “Predictive Energy Management” mode for routing through traffic with optimal battery usage.
2026 BMW X3 Extended Safety Features
BMW prioritizes occupant protection and peace of mind in the 2026 X3 Extended by implementing its most comprehensive safety and driver assistance suite yet. Standard features include front and rear collision mitigation, blind spot detection, rear cross-traffic alert, and automated emergency braking. The vehicle’s new sensor suite includes a front-facing radar with 300m range and side-facing ultrasonic sensors embedded within the redesigned bumpers for a cleaner, more integrated appearance.
Level 2+ semi-autonomous capabilities now come with the Driving Assistant Professional package. This includes Highway Assist, which allows hands-free driving at speeds up to 85 mph on designated highways. The Intelligent Speed Assist system uses camera and GPS data to anticipate speed limit changes and adjust throttle response accordingly. A 3D surround-view camera system and BMW’s Remote Parking Assistant are now enhanced with AI-based object recognition to better identify pets, bicycles, or children near the vehicle.
The X3 Extended also offers BMW’s new Emergency Interior Camera that monitors driver health metrics like heart rate and drowsiness using infrared sensors. In case of a medical emergency, the system can safely bring the vehicle to a stop, activate hazard lights, and contact emergency services. For families, the inclusion of rear-seat occupant alerts and child lock automation increases peace of mind when traveling with young passengers.
