To quote road and track: "The 8HP automatic transmission has received updated gearing with shorter first and second gears, helping the 3-series be quicker off the line. Unfortunately, third gear hasn’t changed, and the resulting spread looks like it’ll cause a big drop in revs between second and third gears."
So BMW aggressively geared it for that fast 0-60... and I think there could be some sort of adaptive ECU algorithm at play that give it more horsepower than advertised during initial acceleration. My guess is they were aiming to match the Tesla dual motor by any means possible. Have you driven the M340i? If you have, you'll notice it has an acceleration flat spot going from gear three to four during rolling acceleration but not so noticeable flat spot if you hit third gear from second gear at WOT during initial acceleration. It's my one knock on the car... inconsistent rolling vs launching acceleration performance.
