The start: 0 to 100 km/h

Off the line, the 430i hits 100 km/h in 5.73 s versus 6.08 s for the i4 eDrive35. Despite lacking instant torque, 258 hp of power compensates. At this point, the 430i leads by 0.35 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 430i is doing 132 km/h against 131 km/h for the i4 eDrive35. The gap is 0.34 s. The gap remains stable from the start.

At 400 metres standing start, the 430i crosses the line in 13.97 s versus 14.38 s. The 0.40 s gap represents roughly 18 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 430i continues to build its lead. At 600 metres, it runs at 185 km/h versus 179 km/h. At 1,000 metres, the 430i finishes in 25.35 s versus 26.26 s, with a 0.91 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the i4 eDrive35 is capped at 190 km/h, the 430i 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 9.27 seconds. The 0.35 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
