Off the line, the S3 Sportback hits 100 km/h in 4.64 s versus 4.74 s for the X3 M40i. The 0.10 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the X3 M40i is doing 142 km/h against 139 km/h for the S3 Sportback. The gap is 0.05 s. The gap remains stable from the start.
At 400 metres standing start, the X3 M40i crosses the line in 12.98 s versus 13.08 s. The 0.11 s gap represents roughly 5 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 X3 M40i and the S3 Sportback 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 (5.19 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 7.65 seconds. The 0.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X3 M40i G01 and S3 Sportback are neck and neck (4,64 s vs 4,74 s, no significant gap).
X3 M40i G01 goes from 0 to 100 km/h in 4,74 seconds (calibrated simulation).
