Off the line, the John Cooper Works FWD hits 100 km/h in 6.21 s versus 6.48 s for the 125d. The 0.27 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the John Cooper Works FWD is doing 137 km/h against 130 km/h for the 125d. The gap is 0.14 s. The challenger starts to claw back ground.
At 400 metres standing start, the John Cooper Works FWD crosses the line in 14.26 s versus 14.67 s. The 0.41 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the John Cooper Works FWD continues to build its lead. At 600 metres, it runs at 191 km/h versus 180 km/h. At 1,000 metres, the John Cooper Works FWD finishes in 25.29 s versus 26.39 s, with a 1.10 s lead. Both vehicles have similar top speeds (251 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.
Electronically capped at 240 km/h, the 125d 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 (5.09 kg/hp vs 6.61 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.81 seconds. The 0.27 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, John Cooper Works FWD wins (6,21 s vs 6,48 s).
