Off the line, the Bmw 128ti hits 100 km/h in 6.22 s versus 6.31 s for the P7i. Despite lacking instant torque, 265 hp of power compensates. The 0.09 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the P7i is doing 129 km/h against 136 km/h for the Bmw 128ti. The gap is 0.05 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 128ti crosses the line in 14.31 s versus 14.56 s. The 0.26 s gap represents roughly 11 m of track - two to three car lengths.
Past 400 metres, the Bmw 128ti continues to build its lead. At 600 metres, it runs at 190 km/h versus 178 km/h. At 1,000 metres, the Bmw 128ti finishes in 25.37 s versus 26.38 s, with a 1.00 s lead.
Both rivals are electronically governed, but not at the same level: the P7i is capped at 200 km/h, the Bmw 128ti at 250 (i.e. 155 mph - industry threshold) 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 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
