Chevrolet Volt Curb Weight: 3,543 lbs

At 60/40, the 3,543 lbs puts about 2,126 lbs on the front axle and 1,417 lbs on the rear — 709 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: 60.6 in of track at the front against 61.8 in at the rear, 1.2 in narrower in front.

The lightest 2015 record is 3,781 lbs; the lightest 2020 record is 3,543 lbs — 238 lbs lighter (6.3%).

At the top of the range the 2020 file reaches 3,543 lbs against 3,781 lbs in 2015, a 238 lbs reduction — driven by which configurations exist, not by the same truck gaining mass.
