Off the line, the John Cooper Works FWD hits 100 km/h in 6.21 s versus 7.44 s for the 420i. Despite the faster sprint time, the 420i is 5 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the John Cooper Works FWD is doing 137 km/h against 117 km/h for the 420i. The gap is 0.33 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 15.38 s. The 1.12 s gap represents roughly 45 m of track - a gap visible to the naked eye.
Past 400 metres, the John Cooper Works FWD continues to build its lead. At 600 metres, it runs at 191 km/h versus 163 km/h. At 1,000 metres, the John Cooper Works FWD finishes in 25.29 s versus 28.23 s, with a 2.94 s lead. Both vehicles have similar top speeds (251 (i.e. 155 mph - industry threshold) vs 238 km/h), preventing any comeback.
Electronically capped at 240 km/h, the 420i 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 8.29 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 1.23 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 7,44 s).
John Cooper Works FWD goes from 0 to 100 km/h in 6,21 seconds (calibrated simulation).
