The start: 0 to 100 km/h

Off the line, the 730d hits 100 km/h in 6.16 s versus 6.58 s for the P7. Despite lacking instant torque, 265 hp of power compensates. At this point, the 730d leads by 0.42 s and sits roughly 5 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 730d is doing 131 km/h against 127 km/h for the P7. The gap is 0.27 s. The challenger starts to claw back ground.

At 400 metres standing start, the 730d crosses the line in 14.36 s versus 14.81 s. The 0.45 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 730d continues to build its lead. At 600 metres, it runs at 183 km/h versus 170 km/h. At 1,000 metres, the 730d finishes in 25.82 s versus 27.64 s, with a 1.82 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 730d 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 10.18 seconds. The 0.42 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
