2026 BMW X3
DIMENSIONS & TECHNICAL SPECS.
EXTERIOR DIMENSIONS: SIZED FOR THE CITY AND THE TRAIL.
The 2026 X3 retains a footprint that balances agility with presence. It has grown slightly over its predecessor, offering a longer wheelbase for improved stability on I-40 without becoming cumbersome to park.
Critical for Tennessee drivers who encounter uneven terrain or steep driveways, the X3 offers substantial ground clearance, 8.5 inches on the 30 xDrive model.

INTERIOR DIMENSIONS & CARGO SPACE.
The interior of the 2026 X3 is a masterclass in spatial efficiency. BMW engineers have maximized the cabin architecture to ensure that five adults ride in comfort, even on long drives to Nashville or Asheville.
The most impressive metric for active families is the cargo capacity. With the rear seats folded flat, the X3 swallows 67.1 cubic feet of gear; enough for bulky furniture, camping equipment, or multiple sets of golf clubs.

TOWING CAPACITY AND PAYLOAD.
Don't let the luxury finish fool you; the 2026 X3 is a capable hauler. When equipped with the optional factory-installed trailer hitch, the X3 punches above its weight class.
The powerful X3 M50 xDrive, utilizing its 3.0-liter inline-6 engine, boasts a maximum towing capacity of 4,850 pounds. This is sufficient to tow a small boat, a pair of jet skis, or a utility trailer with ease. The 4-cylinder X3 30 xDrive is no slouch either, rated for up to 4,001 pounds.
Note on Towing: To achieve these figures safely, we strongly recommend ordering your X3 with the factory towing package, which includes specialized cooling and stability control software.
