Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the Bmw i4 M50 xDrive hits 100 km/h in 3.92 s versus 4.22 s for the P7. The 0.29 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the Bmw i4 M50 xDrive is doing 155 km/h against 147 km/h for the P7. The gap is 0.25 s. The gap remains stable from the start.

At 400 metres standing start, the Bmw i4 M50 xDrive crosses the line in 12.01 s versus 12.54 s. The 0.54 s gap represents roughly 25 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Bmw i4 M50 xDrive continues to build its lead. At 600 metres, it runs at 216 km/h versus 170 km/h. At 1,000 metres, the Bmw i4 M50 xDrive finishes in 21.97 s versus 25.24 s, with a 3.28 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Bmw i4 M50 xDrive is capped at 225 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 (4.07 kg/hp vs 4.81 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.49 seconds. The 0.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
