What are the issues you see in 5-6-7?
I had a miscalculation when browsing the total gear reduction between the final gears in the 6mt and DCT that led me to think that the DCT had a lower gearing.

It just appears to me that gears 5-6-7 seem very closely spaced when 6 and 7 are highway gears. As far as i know the M3 reaches top speed in 5th gear?

I know the V8 doesn't pack low end torque to be able to cruise at 2000 rpms like a Corvette can, but it doesn't mean you should have to cruise at 3000rpm's when there is an extra 7th gear.

Either way i would be interested to hear why they went with lower gearing in the tranny vs. a lower final drive ratio. From what i remember hearing you get the best power delivery when the transmission is at is at 1:1, the DCT would never get to benefit from what.
