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.

How the figure moved since 2015

The lightest 2015 record is 3,461 lbs; the lightest 2026 record is 3,913 lbs — 452 lbs heavier (13.1%).

At the top of the range the 2026 file reaches 3,913 lbs against 3,814 lbs in 2015, a 99 lbs increase — driven by which configurations exist, not by the same truck gaining mass.

Front and rear axle loads

At 55/45, the 3,913 lbs puts about 2,152 lbs on the front axle and 1,761 lbs on the rear — 391 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: 62.2 in of track at the front against 61.8 in at the rear, 0.4 in narrower behind.

Against the rest of the compact cars class

At 3,715 lbs the IS sits within 58 lbs of the 3,657 lbs median for the 22 vehicles EPA files under Compact Cars, with 7 of them heavier.

What is not in the record

EPA files 2 separate 2026 entries for the model, covering 2 engine and drive combinations (3.5L 6-cyl AWD; 3.5L 6-cyl RWD) plus their transmission choices, while NHTSA weighs the body once. Engine and gearbox choice is therefore not reflected in the figure above.

Weights, track and weight distribution from the NHTSA Canadian Vehicle Specifications; powertrain list and MPG from fueleconomy.gov (US DOE).
