Lexus UX Curb Weight: 3,516 lbs

At 57/43, the 3,516 lbs puts about 2,004 lbs on the front axle and 1,512 lbs on the rear — 492 lbs more over the front wheels, which is what front tires and front brake pads wear against first.

The two axles are not the same width either: 61.0 in of track at the front against 61.8 in at the rear, 0.8 in narrower in front.

The lightest 2019 record is 3,307 lbs; the lightest 2026 record is 3,516 lbs — 209 lbs heavier (6.3%).

At the top of the range the 2026 file reaches 3,516 lbs against 3,605 lbs in 2019, a 89 lbs reduction — driven by which configurations exist, not by the same truck gaining mass.

Ranked on the lightest configuration of each nameplate, the UX is 9 of 22 in Compact Cars, 141 lbs below the 3,657 lbs median and lighter than 13 of its peers.

EPA files 4 separate 2026 entries for the model, spanning 42–43 mpg combined, covering 2 engine and drive combinations (2.0L 4-cyl hybrid AWD; 2.0L 4-cyl hybrid FWD) plus their transmission choices, while NHTSA weighs the body once. Engine and gearbox choice is therefore not reflected in the figure above.
