Off the line, the S3 Sedan hits 100 km/h in 4.63 s versus 4.78 s for the X3 M40i. At this point, the S3 Sedan leads by 0.15 s and sits roughly 3 m ahead.
At 200 metres, the S3 Sedan is doing 138 km/h against 142 km/h for the X3 M40i. The gap is 0.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the X3 M40i crosses the line in 13.02 s versus 13.08 s. The 0.06 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, the X3 M40i continues to build its lead. At 600 metres, it runs at 197 km/h versus 198 km/h. At 1,000 metres, the X3 M40i finishes in 23.67 s versus 23.69 s, with a 0.01 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the X3 M40i and the S3 Sedan are governed to 250 (i.e. 155 mph - industry threshold) 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 combustion powertrains, the difference comes down to power-to-weight ratio (5.13 kg/hp vs 4.61 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.68 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S3 Sedan wins (4,63 s vs 4,78 s).
X3 M40i G01 goes from 0 to 100 km/h in 4,78 seconds (calibrated simulation).
