Off the line, the M4 Convertible hits 100 km/h in 4.69 s versus 6.21 s for the John Cooper Works FWD. At this point, the M4 Convertible leads by 1.52 s and sits roughly 17 m ahead.
At 200 metres, the M4 Convertible is doing 151 km/h against 137 km/h for the John Cooper Works FWD. The gap is 1.17 s. The challenger starts to claw back ground.
At 400 metres standing start, the M4 Convertible crosses the line in 12.64 s versus 14.26 s. The 1.62 s gap represents roughly 75 m of track - a gap visible to the naked eye.
Past 400 metres, the M4 Convertible continues to build its lead. At 600 metres, it runs at 213 km/h versus 191 km/h. At 1,000 metres, the M4 Convertible finishes in 22.51 s versus 25.29 s, with a 2.78 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 251 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the M4 Convertible never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.15 kg/hp vs 5.09 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.88 seconds. The 1.52 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 Convertible F82 wins (4,69 s vs 6,21 s).
