Jaguar I-PACE EV400 vs BMW X3 M40d G01: which is truly faster?

Off the line, the I-PACE EV400 hits 100 km/h in 4.84 s versus 4.87 s for the Bmw X3 M40d. The instant torque of 696 Nm from the electric motor makes the difference. The 0.04 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Bmw X3 M40d is doing 138 km/h against 141 km/h for the I-PACE EV400. The gap is 0.03 s. The gap remains stable from the start.

At 400 metres standing start, the I-PACE EV400 crosses the line in 13.18 s versus 13.21 s. The 0.03 s gap represents roughly 1 m of track

Past 400 metres, the situation changes. The I-PACE EV400 maxes out at 200 km/h while the Bmw X3 M40d keeps accelerating towards 250 (i.e. 155 mph — industry threshold) km/h. At 600 metres, the gap has dropped to 0.06 s.

Around 897 metres, both vehicles are level. This is the inversion point: the Bmw X3 M40d overcomes its launch deficit thanks to a 50 km/h higher top speed.

At 1,000 metres, the Bmw X3 M40d finishes in 24.24 s versus 24.36 s. The 0.11 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the I-PACE EV400 is capped at 200 km/h, the Bmw X3 M40d 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 7.63 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
