> Perseverance has better instruments, but is the same platform and weight because there's no rockets capable of putting anything larger on Mars. Actually this statement has two mistakes. First, despite Curiosity and Perseverance indeed share the platform, later is 150kg heavier (1050kg vs 899kg). Second, there are rockets, which are more performant than Atlas V 541, which launched the Perseverance [1]: Atlas V 551, Ariane 5 ECA, Long March 5, Delta IV Heavy, Falcon Heavy (expended).
