America’s FASTEST BMW M5 1356BHP on the STREET! Acceleration & Sound by turboandstance - November 4, 2025 In this episode, we take a ride in the fastest F90 BMW M5 in the United States — a fully-built, AWD monster pushing over 1,100+ WHP and capable of 8.8-second quarter-mile passes. From the outside, it still carries the presence of a luxury family sedan… until you notice the cage, beadlock wheels, and the parachute hanging off the back. Built from the block up with a sleeved S63, custom turbos, cams, fueling upgrades, and a sequential-sharp transmission setup, this M5 is a statement of pure intent: daily-driven comfort meets drag-strip brutality. What makes this car even crazier is that it’s not just a track toy — the owner still puts a child seat in the back when the cage isn’t installed. This is a car that can run high 8s, then cruise home like nothing happened. No off-the-shelf parts here — nearly everything is custom-fabricated, developed through trial, failure, and relentless refinement. It’s rare to see someone push the F90 platform to this level. Consider this your reminder: the V8, twin-turbo M5 is far from done. For more content like this one follow us also on Facebook, Pinterest or Instagram!
