You are confusing some metric vs imperial values here.
M4CS is 3.9 seconds 0-100km/h, not to 60mph
M4 CS was advertised as 460hpDIN/454hpSAE and 442lb-ft. Those figure were quoted as “preliminary” in the press release. I assume the final number is now at 453hpSAE. I can only assume the power and torque ratings will be identical for both cars.
EDIT: The international press release states the M3CS at 338kw/460hpDIN 600N-m/442lb-ft, same as the M4CS. I guess the discrepancy resides in the unit conversions and round-up. 338kW=453.3hpSAE -> 338kW=459.5hpDIN -> 460hpDIN=453.7hpSAE -> 600N-m=442.5lb-ft
Good catch with the Mg oil sump.
Interesting about the difference in ground clearance and oil capacity. The later does not really make sense sinse they share the same engine.
Regarding air resistance, something is off too as the technical specs show the same frontal area for both cars, and the M3 has a larger frontal area than the M4.
