The 2025 BMW M5 has once again proven that BMW's official power figures are far from the full story. A recent dyno test conducted by IND Distribution reveals that the new M5 produces a staggering 696 horsepower and 730 lb-ft of torque at the wheels. These figures significantly exceed BMW's official claims, continuing the tradition of understated M.

In this video, we put the new BMW G90 M5 on the dyno at MSL Performance to find out whether it truly delivers BMW's claimed 727 horsepower. Tested on 99 RON fuel with a fully charged hybrid. This is the seventh and most powerful generation of the super sedan to date, and when the 2025 M5 was revealed, BMW quoted a figure of 717 horsepower, along with 738 lb.

UK-based Evolve Automotive has recently strapped a G90 BMW M5 to their dyno. As expected of an M car, BMW has been rather conservative with its declared output ratings. With 99.

At the heart of the G90-generation BMW M5 is a bi-turbocharged 4.4-liter V-8, which, on its own, produces 577 peak horsepower between 5,600 and 6,500 rpm, and 553 pound-feet of torque from 1,800. 2025 M5 G90 AWD Dyno Results (post break-in): 678whp / 723wtq Engine, Exhaust, Drivetrain, Tuning Modifications.
