Off the line, the 540d xDrive hits 100 km/h in 4.64 s versus 4.69 s for the iX xDrive50. Despite lacking instant torque, 340 hp of power compensates. The 0.05 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 540d xDrive is doing 142 km/h against 144 km/h for the iX xDrive50. The gap is 0.07 s. The gap remains stable from the start.
At 400 metres standing start, the 540d xDrive crosses the line in 12.90 s versus 12.93 s. The 0.03 s gap represents roughly 2 m of track
Past 400 metres, the 540d xDrive continues to build its lead. At 600 metres, it runs at 199 km/h versus 200 km/h. At 1,000 metres, the 540d xDrive finishes in 23.41 s versus 23.92 s, with a 0.51 s lead.
Both rivals are electronically governed, but not at the same level: the iX xDrive50 is capped at 200 km/h, the 540d 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 7.16 seconds. The 0.05 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, iX xDrive50 I20 and 540d xDrive G30 are neck and neck (4,63 s vs 4,69 s, no significant gap).
iX xDrive50 I20 goes from 0 to 100 km/h in 4,69 seconds (calibrated simulation).
iX xDrive50 I20: 523 hp, ratio 4,94 kg/hp. 540d xDrive G30: 340 hp, ratio 5,44 kg/hp.
iX xDrive50 I20: 200 km/h. 540d xDrive G30: 250 km/h.
