Off the line, the Bmw 125i hits 100 km/h in 6.15 s versus 7.76 s for the DS4 PureTech 225 EAT8. At this point, the Bmw 125i leads by 1.61 s and sits roughly 22 m ahead.
At 200 metres, the Bmw 125i is doing 131 km/h against 126 km/h for the DS4 PureTech 225 EAT8. The gap is 1.10 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 125i crosses the line in 14.35 s versus 15.61 s. The 1.25 s gap represents roughly 54 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 125i continues to build its lead. At 600 metres, it runs at 182 km/h versus 178 km/h. At 1,000 metres, the Bmw 125i finishes in 25.91 s versus 27.41 s, with a 1.50 s lead. Both vehicles have similar top speeds (245 vs 243 km/h), preventing any comeback.
Electronically capped at 243 km/h, the Bmw 125i 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 (6.49 kg/hp vs 6.25 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.04 seconds. The 1.61 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
