Off the line, the XC40 B4 hits 100 km/h in 8.23 s versus 9.82 s for the A3 Sedan. At this point, the XC40 B4 leads by 1.59 s and sits roughly 16 m ahead.
At 200 metres, the XC40 B4 is doing 115 km/h against 108 km/h for the A3 Sedan. The gap is 0.78 s. The challenger starts to claw back ground.
At 400 metres standing start, the XC40 B4 crosses the line in 16.10 s versus 17.21 s. The 1.10 s gap represents roughly 41 m of track - a gap visible to the naked eye.
Past 400 metres, the XC40 B4 continues to build its lead. At 600 metres, it runs at 158 km/h versus 151 km/h. At 1,000 metres, the XC40 B4 finishes in 29.39 s versus 31.15 s, with a 1.76 s lead. Despite a higher top speed (215 km/h), the A3 Sedan never recovers its launch deficit.
Electronically capped at 180 km/h, the XC40 B4 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 combustion powertrains, the difference comes down to power-to-weight ratio (8.17 kg/hp vs 11.34 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.05 seconds. The 1.59 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, XC40 B4 wins (8,23 s vs 9,82 s).
XC40 B4 goes from 0 to 100 km/h in 8,23 seconds (calibrated simulation).
