The start: 0 to 100 km/h

Off the line, the i4 eDrive35 hits 100 km/h in 6.08 s versus 6.58 s for the P7. At this point, the i4 eDrive35 leads by 0.50 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the i4 eDrive35 is doing 131 km/h against 127 km/h for the P7. The gap is 0.28 s. The challenger starts to claw back ground.

At 400 metres standing start, the i4 eDrive35 crosses the line in 14.38 s versus 14.81 s. The 0.43 s gap represents roughly 19 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the i4 eDrive35 continues to build its lead. At 600 metres, it runs at 179 km/h versus 170 km/h. At 1,000 metres, the i4 eDrive35 finishes in 26.26 s versus 27.64 s, with a 1.38 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 P7 at 170 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.

With two electric powertrains, the difference comes down to power-to-weight ratio (6.99 kg/hp vs 7.59 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.18 seconds. The 0.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
