The start: 0 to 100 km/h

Off the line, the 750Ld xDrive hits 100 km/h in 4.63 s versus 4.69 s for the iX xDrive50. Despite lacking instant torque, 400 hp of power compensates. The 0.06 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 750Ld xDrive is doing 145 km/h against 144 km/h for the iX xDrive50. The gap is 0.06 s. The gap remains stable from the start.

At 400 metres standing start, the 750Ld xDrive crosses the line in 12.84 s versus 12.93 s. The 0.09 s gap represents roughly 4 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 750Ld xDrive continues to build its lead. At 600 metres, it runs at 203 km/h versus 200 km/h. At 1,000 metres, the 750Ld xDrive finishes in 23.18 s versus 23.92 s, with a 0.74 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the iX xDrive50 is capped at 200 km/h, the 750Ld xDrive at 250 (i.e. 155 mph - industry threshold) 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 7.07 seconds. The 0.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
