Off the line, the Q4 45 e-tron 210 kW hits 100 km/h in 6.77 s versus 6.86 s for the Bmw iX3. The 0.09 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Q4 45 e-tron 210 kW is doing 125 km/h against 126 km/h for the Bmw iX3. The gap is 0.11 s. The gap remains stable from the start.
At 400 metres standing start, the Q4 45 e-tron 210 kW crosses the line in 14.98 s versus 15.07 s. The 0.09 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.10 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.
Both rivals share the same electronic speed cap: the Q4 45 e-tron 210 kW and the Bmw iX3 are governed to 180 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two electric powertrains, the difference comes down to power-to-weight ratio (7.50 kg/hp vs 7.64 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.55 seconds. The 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
