Under the bonnet

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 eDrive35 hits 100 km/h in 6.08 s versus 6.31 s for the P7i. The 0.23 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the Bmw i4 eDrive35 is doing 131 km/h against 129 km/h for the P7i. The gap is 0.10 s. The challenger starts to claw back ground.

At 400 metres standing start, the Bmw i4 eDrive35 crosses the line in 14.38 s versus 14.56 s. The 0.19 s gap represents roughly 8 m of track — barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The Bmw i4 eDrive35 maxes out at 190 km/h while the P7i keeps accelerating towards 200 km/h. At 600 metres, the gap has dropped to 0.24 s.

At 1,000 metres, the Bmw i4 eDrive35 finishes in 26.26 s versus 26.38 s, with just 0.12 s to spare. The P7i fails to fully close the launch gap.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Bmw i4 eDrive35 is capped at 190 km/h, the P7i at 200 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 7.18 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.78 seconds. The 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
