The start: 0 to 100 km/h

Off the line, the P7i hits 100 km/h in 6.31 s versus 7.60 s for the 220i Convertible. The instant torque of 430 Nm from the electric motor makes the difference. At this point, the P7i leads by 1.29 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the P7i is doing 129 km/h against 118 km/h for the 220i Convertible. The gap is 0.53 s. The challenger starts to claw back ground.

At 400 metres standing start, the P7i crosses the line in 14.56 s versus 15.54 s. The 0.98 s gap represents roughly 39 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the P7i continues to build its lead. At 600 metres, it runs at 178 km/h versus 163 km/h. At 1,000 metres, the P7i finishes in 26.38 s versus 28.42 s, with a 2.05 s lead. Despite a higher top speed (226 km/h), the 220i Convertible never recovers its launch deficit.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the P7i is capped at 200 km/h, the 220i Convertible at 226 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 12.27 seconds. The 1.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
