The start: 0 to 100 km/h

Off the line, the iX xDrive40 hits 100 km/h in 6.04 s versus 7.41 s for the Atto 3 Extended Range. At this point, the iX xDrive40 leads by 1.37 s and sits roughly 20 m ahead.

From 100 km/h to 400 metres

At 200 metres, the iX xDrive40 is doing 127 km/h against 121 km/h for the Atto 3 Extended Range. The gap is 0.94 s. The challenger starts to claw back ground.

At 400 metres standing start, the iX xDrive40 crosses the line in 14.36 s versus 15.57 s. The 1.20 s gap represents roughly 48 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 160 km/h. At 1,000 metres, the iX xDrive40 finishes in 26.37 s versus 29.19 s, with a 2.82 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 Atto 3 Extended Range at 160 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 8.58 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.71 seconds. The 1.37 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
