Its the same reason that the Panamera Turbo can outlap the M3 on any given track despite it weighing 4300 lbs.
E92 M3 3,704/414= 8.95
E46 M3 3,415/333= 10.26
E82 1M 3,461/335= 10.33
E92 M3 is even farther ahead of E82 1M in power to weight ratio because weight difference is not 300 lbs, it is only 243 lbs.
