Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the iX xDrive40 hits 100 km/h in 6.04 s versus 6.86 s for the iX3. At this point, the iX xDrive40 leads by 0.82 s and sits roughly 17 m ahead.

From 100 km/h to 400 metres

At 200 metres, the iX xDrive40 is doing 127 km/h against 126 km/h for the iX3. The gap is 0.67 s. The challenger starts to claw back ground.

At 400 metres standing start, the iX xDrive40 crosses the line in 14.36 s versus 15.07 s. The 0.71 s gap represents roughly 30 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the iX xDrive40 continues to build its lead. At 600 metres, it runs at 175 km/h versus 172 km/h. At 1,000 metres, the iX xDrive40 finishes in 26.37 s versus 27.54 s, with a 1.17 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the iX xDrive40 is capped at 200 km/h, the iX3 at 180 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.

With two electric powertrains, the difference comes down to power-to-weight ratio (7.48 kg/hp vs 7.64 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.53 seconds. The 0.82 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
