The start: 0 to 100 km/h

Off the line, the iX3 hits 100 km/h in 6.86 s versus 6.88 s for the Prius PHEV. The 0.02 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the Prius PHEV is doing 121 km/h against 126 km/h for the iX3. The gap is 0.12 s. The gap widens compared to the 0-100.

At 400 metres standing start, the iX3 crosses the line in 15.07 s versus 15.09 s. The 0.02 s gap represents roughly 1 m of track

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. The iX3 maxes out at 180 km/h while the Prius PHEV keeps accelerating towards 262 km/h. At 600 metres, the gap has dropped to 0.11 s.

Around 951 metres, both vehicles are level. This is the inversion point: the Prius PHEV overcomes its launch deficit thanks to a 82 km/h higher top speed.

At 1,000 metres, the Prius PHEV finishes in 27.46 s versus 27.54 s. The 0.07 s delta shows an extremely tight race.

What the numbers don’t tell you

Electronically capped at 180 km/h, the iX3 never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (7.64 kg/hp vs 6.91 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.22 seconds. The 0.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
