Off the line, the Bmw 545e xDrive hits 100 km/h in 4.68 s versus 6.12 s for the Bmw X7 xDrive40d. The instant torque of 600 Nm from the electric motor makes the difference. At this point, the Bmw 545e xDrive leads by 1.45 s and sits roughly 9 m ahead.
At 200 metres, the Bmw 545e xDrive is doing 143 km/h against 126 km/h for the Bmw X7 xDrive40d. The gap is 0.87 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 545e xDrive crosses the line in 12.91 s versus 14.39 s. The 1.48 s gap represents roughly 62 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 545e xDrive continues to build its lead. At 600 metres, it runs at 200 km/h versus 174 km/h. At 1,000 metres, the Bmw 545e xDrive finishes in 23.40 s versus 26.45 s, with a 3.06 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 245 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 545e xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 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 1.45 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 545e xDrive G30 wins (4,67 s vs 6,12 s).
545e xDrive G30 goes from 0 to 100 km/h in 4,67 seconds (calibrated simulation).
