Off the line, the S3 Sportback hits 100 km/h in 4.64 s versus 4.78 s for the M135i xDrive. At this point, the S3 Sportback leads by 0.14 s and sits roughly 4 m ahead.
At 200 metres, the S3 Sportback is doing 139 km/h against 144 km/h for the M135i xDrive. The gap is 0.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the M135i xDrive crosses the line in 13.00 s versus 13.08 s. The 0.08 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, the M135i xDrive continues to build its lead. At 600 metres, it runs at 199 km/h versus 197 km/h. At 1,000 metres, the M135i xDrive finishes in 23.59 s versus 23.72 s, with a 0.13 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 S3 Sportback and the M135i xDrive 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 (4.61 kg/hp vs 4.98 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 0.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
