BMW iX M60 I20 vs BMW X5 xDrive30d G05: which is truly faster?

Off the line, the iX M60 hits 100 km/h in 3.72 s versus 6.05 s for the X5 xDrive30d. The instant torque of 1,100 Nm from the electric motor makes the difference. At this point, the iX M60 leads by 2.34 s and sits roughly 14 m ahead.

At 200 metres, the iX M60 is doing 151 km/h against 125 km/h for the X5 xDrive30d. The gap is 1.48 s. The challenger starts to claw back ground.

At 400 metres standing start, the iX M60 crosses the line in 11.94 s versus 14.33 s. The 2.39 s gap represents roughly 98 m of track - a gap visible to the naked eye.

Past 400 metres, the iX M60 continues to build its lead. At 600 metres, it runs at 212 km/h versus 172 km/h. At 1,000 metres, the iX M60 finishes in 21.84 s versus 26.57 s, with a 4.73 s lead.

Both rivals are electronically governed, but not at the same level: the iX M60 is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X5 xDrive30d at 235 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 10.01 seconds. The 2.34 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
