Off the line, the P7 hits 100 km/h in 4.22 s versus 6.12 s for the X7 xDrive40d. The instant torque of 655 Nm from the electric motor makes the difference. At this point, the P7 leads by 1.91 s and sits roughly 12 m ahead.
At 200 metres, the P7 is doing 147 km/h against 126 km/h for the X7 xDrive40d. The gap is 1.19 s. The challenger starts to claw back ground.
At 400 metres standing start, the P7 crosses the line in 12.54 s versus 14.39 s. The 1.85 s gap represents roughly 77 m of track - a gap visible to the naked eye.
Past 400 metres, the gap narrows. The P7 maxes out at 170 km/h while the X7 xDrive40d keeps accelerating towards 245 km/h. At 600 metres, the gap is down to 1.97 s from 1.85 s at 400 metres.
At 1,000 metres, the P7 finishes in 25.24 s versus 26.45 s, with just 1.21 s to spare. The X7 xDrive40d fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the P7 is capped at 170 km/h, the X7 xDrive40d at 245 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 9.90 seconds. The 1.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, P7 wins (4,21 s vs 6,12 s).
P7 goes from 0 to 100 km/h in 4,21 seconds (calibrated simulation).
