Now to something different. For curiousity, M3 V8 with manual gearbox reach 180km/h on the speedo in third gear.
How fast is C63 going in third gear, anyone?
The calculated maximum geared speed for an M3 in 3rd gear @ max rpm (8400 rpm) is 169 km/h. So yes, theoretically you may just have reached an indicated speed on the clock of 180 km/h in 3rd.
I don't have the figures for the C63. But I imagine that the combination of a lower redline and a lower gear ratio in the C63 (1.92:1) translates to a geared speed of around 155 km/h true speed.
