The start: 0 to 100 km/h

Off the line, the 125i hits 100 km/h in 6.15 s versus 7.35 s for the ID.3 Pro. Despite lacking instant torque, 224 hp of power compensates. At this point, the 125i leads by 1.20 s and sits roughly 11 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 125i is doing 131 km/h against 121 km/h for the ID.3 Pro. The gap is 0.69 s. The challenger starts to claw back ground.

At 400 metres standing start, the 125i crosses the line in 14.35 s versus 15.50 s. The 1.14 s gap represents roughly 46 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 125i continues to build its lead. At 600 metres, it runs at 182 km/h versus 160 km/h. At 1,000 metres, the 125i finishes in 25.91 s versus 29.13 s, with a 3.22 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 125i is capped at 243 km/h, the ID.3 Pro 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 11.71 seconds. The 1.20 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
