The start: 0 to 100 km/h

Off the line, the P7 hits 100 km/h in 4.22 s versus 7.05 s for the 320i. The instant torque of 655 Nm from the electric motor makes the difference. At this point, the P7 leads by 2.84 s and sits roughly 15 m ahead.

From 100 km/h to 400 metres

At 200 metres, the P7 is doing 147 km/h against 119 km/h for the 320i. The gap is 1.63 s. The challenger starts to claw back ground.

At 400 metres standing start, the P7 crosses the line in 12.54 s versus 15.11 s. The 2.57 s gap represents roughly 101 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the P7 continues to build its lead. At 600 metres, it runs at 170 km/h versus 166 km/h. At 1,000 metres, the P7 finishes in 25.24 s versus 27.81 s, with a 2.56 s lead. Despite a higher top speed (234 km/h), the 320i never recovers its launch deficit.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the P7 is capped at 170 km/h, the 320i at 235 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 11.54 seconds. The 2.84 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
