Off the line, the Bmw 545e xDrive hits 100 km/h in 4.68 s versus 5.33 s for the Bmw X7 xDrive50i. The instant torque of 600 Nm from the electric motor makes the difference. At this point, the Bmw 545e xDrive leads by 0.66 s and sits roughly 7 m ahead.
At 200 metres, the Bmw 545e xDrive is doing 143 km/h against 137 km/h for the Bmw X7 xDrive50i. The gap is 0.46 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 13.57 s. The 0.66 s gap represents roughly 31 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 190 km/h. At 1,000 metres, the Bmw 545e xDrive finishes in 23.40 s versus 24.64 s, with a 1.24 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the Bmw X7 xDrive50i and the Bmw 545e xDrive are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
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 8.16 seconds. The 0.66 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 5,33 s).
