BMW M3 G80 G82 - View Single Post - Why not raise the redline to 7200 RPM for the 6MT?

Time to geek out a bit. I believe there would indeed a bit more performance to be had through a higher redline with the 6MT given its gear ratios. From the S58 technical doc, we know the S58 can still theoretically make ~460hp (~345kW) up to 7,500rpm.

Using the gear ratios published in the press release, we can find the RPM in the next gear when shifting at redline. Knowing that torque plateaus at 406lb-ft from 2,650 to 6,130rpm, we can calculate the power in the next gear. As you can see, the starting power falls quite significantly below 460hp in the lower gears:
