The start: 0 to 100 km/h

Off the line, the 750Li xDrive hits 100 km/h in 4.05 s versus 4.22 s for the P7. Despite lacking instant torque, 530 hp of power compensates. Despite the faster sprint time, the P7 is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

From 100 km/h to 400 metres

At 200 metres, the 750Li xDrive is doing 162 km/h against 147 km/h for the P7. The gap is 0.24 s. The gap remains stable from the start.

At 400 metres standing start, the 750Li xDrive crosses the line in 11.80 s versus 12.54 s. The 0.74 s gap represents roughly 35 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 750Li xDrive continues to build its lead. At 600 metres, it runs at 229 km/h versus 170 km/h. At 1,000 metres, the 750Li xDrive finishes in 21.02 s versus 25.24 s, with a 4.22 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 750Li xDrive is capped at 250 (i.e. 155 mph - industry threshold) 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.

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 6.49 seconds. The 0.17 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
