Bmw M5 2025 Weight Kg To Lbs. But it’s a midsize premium crossover, not a performance sedan. Whereas the outgoing m5 sedan has a curb weight of 4,345 lbs (1,971 kg), the incoming 2025 m5 weighs a whopping 5,390 lbs (2,445 kg).

What really underscores the m5’s weight gain is comparing it to the new 2025 x5, which is no welterweight at 4,998 lbs. Tracking the weight increase across m5 generations, we see a relatively gradual trend until now.
