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 midsize cars class

Ranked on the lightest configuration of each nameplate, the CT5 is 20 of 44 in Midsize Cars, 183 lbs below the 3,843 lbs median and lighter than 24 of its peers.

What four-wheel drive costs in weight

Across the 2 body styles recorded in both layouts, four-wheel drive adds between 139 lbs and 170 lbs — roughly 4.0% of the two-wheel-drive weight. The transfer case, front differential and driveshaft account for that in every case, so the penalty barely moves with cab size.

4dr Sedan RWD+139 lbs3,660 lbs → 3,799 lbs

Where the mass sits: 51/49

NHTSA records a 51/49 distribution, so the 3,660 lbs splits to roughly 1,866 lbs on the front axle and 1,794 lbs on the rear.

The two axles are not the same width either: 63.0 in of track at the front against 63.8 in at the rear, 0.8 in narrower in front.

Unchanged since 2020

All 7 model years from 2020 to 2026 are filed at 4,145 lbs, so the model year on a listing does not change the figure.
