The start: 0 to 100 km/h

Off the line, the X3 xDrive30d hits 100 km/h in 5.62 s versus 6.86 s for the iX3. Despite lacking instant torque, 286 hp of power compensates. At this point, the X3 xDrive30d leads by 1.24 s and sits roughly 21 m ahead.

From 100 km/h to 400 metres

At 200 metres, the X3 xDrive30d is doing 130 km/h against 126 km/h for the iX3. The gap is 0.93 s. The challenger starts to claw back ground.

At 400 metres standing start, the X3 xDrive30d crosses the line in 13.96 s versus 15.07 s. The 1.11 s gap represents roughly 47 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the X3 xDrive30d continues to build its lead. At 600 metres, it runs at 180 km/h versus 172 km/h. At 1,000 metres, the X3 xDrive30d finishes in 25.66 s versus 27.54 s, with a 1.88 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the iX3 is capped at 180 km/h, the X3 xDrive30d 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 10.53 seconds. The 1.24 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
