The various powers/abilities/motives/motifs of characters in comic books changes depending on the time period, who's writing them, among other things. Superman for instance used to simply have superhuman strength and invulnerability, and got around by running and leaping long distances (he can leap tall buildings in a single bound!), and primarily gained his ability to fly due to radio show depictions, and then because it was cheaper (and less silly, apparently) to animate flying than leaping for the original Fleischer cartoons. At one point his powers were considered standard for Kryptonians even before Krypton was destroyed, but was later retconned to be a side effect of being exposed to earth's yellow sun (Krypton had a red sun).
As such, consider the depictions of Wonder Woman you're referencing, specifically comparing modern versions to the Lynda Carter version of the 1970s TV show. Showing superhuman strength such as hurtling tanks and large objects is a costly endeavor, more so when you have to rely on more practical effects because it's the 1970s. In general, though, Diana has typically been depicted as having strength on par with that of Superman.
Characters and their depictions change over time, depending on who's writing them, what era they're in, and even what budgets for the medium will allow.
