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.

Front and rear axle loads

At 58/42, the 4,288 lbs puts about 2,487 lbs on the front axle and 1,801 lbs on the rear — 686 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: 65.4 in of track at the front against 66.5 in at the rear, 1.2 in narrower in front.

Against the rest of the small sport utility vehicle 4wd class

Ranked on the lightest configuration of each nameplate, the RX is 75 of 98 in Small Sport Utility Vehicle 4WD, 340 lbs above the 3,948 lbs median and lighter than 23 of its peers.

How the figure moved since 2016

The lightest 2016 record is 4,453 lbs; the lightest 2026 record is 4,288 lbs — 165 lbs lighter (3.7%).

At the top of the range the 2026 file reaches 4,751 lbs against 4,740 lbs in 2016, a 11 lbs increase — driven by which configurations exist, not by the same truck gaining mass.
