Tesla Model X P90D vs BMW X5 M Competition G05: which is truly faster?

Off the line, the Model X P90D hits 100 km/h in 3.32 s versus 3.83 s for the Bmw X5 M Competition. The instant torque of 967 Nm from the electric motor makes the difference. At this point, the Model X P90D leads by 0.51 s and sits roughly 4 m ahead.

At 200 metres, the Model X P90D is doing 166 km/h against 155 km/h for the Bmw X5 M Competition. The gap is 0.47 s. The gap remains stable from the start.

At 400 metres standing start, the Model X P90D crosses the line in 11.18 s versus 11.94 s. The 0.76 s gap represents roughly 40 m of track — a gap visible to the naked eye.

Past 400 metres, the Model X P90D continues to build its lead. At 600 metres, it runs at 231 km/h versus 215 km/h. At 1,000 metres, the Model X P90D finishes in 20.35 s versus 21.80 s, with a 1.45 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 Model X P90D and the Bmw X5 M Competition are governed to 249 (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 5.72 seconds. The 0.51 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
