Off the line, the Focus ST 250 Gen3 hits 100 km/h in 6.43 s versus 8.14 s for the 420i Convertible. At this point, the Focus ST 250 Gen3 leads by 1.71 s and sits roughly 4 m ahead.
At 200 metres, the Focus ST 250 Gen3 is doing 134 km/h against 115 km/h for the 420i Convertible. The gap is 0.64 s. The challenger starts to claw back ground.
At 400 metres standing start, the Focus ST 250 Gen3 crosses the line in 14.55 s versus 15.96 s. The 1.41 s gap represents roughly 55 m of track - a gap visible to the naked eye.
Past 400 metres, the Focus ST 250 Gen3 continues to build its lead. At 600 metres, it runs at 188 km/h versus 161 km/h. At 1,000 metres, the Focus ST 250 Gen3 finishes in 25.77 s versus 28.97 s, with a 3.20 s lead.
Electronically capped at 236 km/h, the 420i 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 (5.56 kg/hp vs 9.18 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.10 seconds. The 1.71 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Focus ST 250 Gen3 wins (6,43 s vs 8,14 s).
Focus ST 250 Gen3 goes from 0 to 100 km/h in 6,43 seconds (calibrated simulation).
