Off the line, the Bmw 128ti hits 100 km/h in 6.27 s versus 6.81 s for the Bmw i3s (120 Ah). Despite lacking instant torque, 265 hp of power compensates. At this point, the Bmw 128ti leads by 0.54 s and sits roughly 2 m ahead.
At 200 metres, the Bmw 128ti is doing 132 km/h against 124 km/h for the Bmw i3s (120 Ah). The gap is 0.25 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 128ti crosses the line in 14.44 s versus 15.05 s. The 0.61 s gap represents roughly 25 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 184 km/h versus 160 km/h. At 1,000 metres, the Bmw 128ti finishes in 25.86 s versus 28.59 s, with a 2.73 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 128ti is capped at 250 (i.e. 155 mph — industry threshold) km/h, the Bmw i3s (120 Ah) at 160 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 10.76 seconds. The 0.54 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
