Off the line, the 125i hits 100 km/h in 6.15 s versus 6.31 s for the P7i. Despite lacking instant torque, 224 hp of power compensates. The 0.16 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 125i is doing 131 km/h against 129 km/h for the P7i. The gap is 0.09 s. The gap remains stable from the start.
At 400 metres standing start, the 125i crosses the line in 14.35 s versus 14.56 s. The 0.21 s gap represents roughly 9 m of track - barely a car length.
Past 400 metres, the 125i continues to build its lead. At 600 metres, it runs at 182 km/h versus 178 km/h. At 1,000 metres, the 125i finishes in 25.91 s versus 26.38 s, with a 0.47 s lead.
Both rivals are electronically governed, but not at the same level: the P7i is capped at 200 km/h, the 125i at 243 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.78 seconds. The 0.16 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 125i F20LCI wins (6,15 s vs 6,31 s).
P7i goes from 0 to 100 km/h in 6,31 seconds (calibrated simulation).
