Curb weights sourced from the NHTSA Canadian Vehicle Specifications database and recorded per body style, with fluids and a full fuel tank but no occupants or cargo.

Against the rest of the two seaters class

At 3,296 lbs the Z4 sits within 88 lbs of the 3,384 lbs median for the 24 vehicles EPA files under Two Seaters, with 15 of them heavier.

How the figure moved since 2015

The lightest 2015 record is 3,263 lbs; the lightest 2026 record is 3,296 lbs — 33 lbs heavier (1.0%).

At the top of the range the 2026 file reaches 3,463 lbs against 3,494 lbs in 2015, a 31 lbs reduction — driven by which configurations exist, not by the same truck gaining mass.

Where the mass sits: 50/50

NHTSA records a 50/50 distribution, so the 3,296 lbs splits to roughly 1,648 lbs on the front axle and 1,648 lbs on the rear.

The two axles are not the same width either: 63.8 in of track at the front against 63.4 in at the rear, 0.4 in narrower behind.
