The start: 0 to 100 km/h

Off the line, the iX3 hits 100 km/h in 6.86 s versus 7.04 s for the 420d. The instant torque of 400 Nm from the electric motor makes the difference. Despite the faster sprint time, the 420d is 11 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

From 100 km/h to 400 metres

At 200 metres, the 420d is doing 119 km/h against 126 km/h for the iX3. The gap is 0.24 s. The gap remains stable from the start.

At 400 metres standing start, the iX3 crosses the line in 15.07 s versus 15.10 s. The 0.03 s gap represents roughly 1 m of track

Beyond 400 metres: top speed comes into play

Past 400 metres, the iX3 continues to build its lead. At 600 metres, it runs at 172 km/h versus 166 km/h. At 1,000 metres, the iX3 finishes in 27.54 s versus 27.77 s, with a 0.24 s lead. Despite a higher top speed (240 km/h), the 420d never recovers its launch deficit.

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 420d at 240 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 11.60 seconds. The 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
