Wheelbase
The distance between the front and rear axle centers, a dimension worth reading alongside overall length to see how a car's length is packaged.
Wheelbase is measured from the center of the front wheels to the center of the rear ones, and it is the dimension to check when overall length alone says little. The cabin sits between the axles, so two cars of the same length can split that length differently: a longer wheelbase means shorter overhangs beyond the wheels, and the reverse. Geometry also ties wheelbase to maneuvering, since a longer wheelbase, all else equal, gives a larger turning circle.
Hyundai says its dedicated electric platform makes deliberate use of this. Hyundai says its E-GMP platform uses a long wheelbase, short overhangs, and a battery pack under the floor to maximize interior space. Comparing wheelbase against overall length is a quick way to spot such packaging on a spec sheet, though the interior figures are what confirm it.
CarPairly stores wheelbase in millimeters and shows inches alongside for US and UK visitors, like every dimension on the site.
