The start: 0 to 100 km/h

Off the line, the M240i xDrive hits 100 km/h in 4.45 s versus 4.64 s for the S3 Sportback. At this point, the M240i xDrive leads by 0.19 s and sits roughly 1 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M240i xDrive is doing 147 km/h against 139 km/h for the S3 Sportback. The gap is 0.25 s. The gap remains stable from the start.

At 400 metres standing start, the M240i xDrive crosses the line in 12.66 s versus 13.08 s. The 0.42 s gap represents roughly 20 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M240i xDrive continues to build its lead. At 600 metres, it runs at 203 km/h versus 197 km/h. At 1,000 metres, the M240i xDrive finishes in 23.03 s versus 23.72 s, with a 0.69 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.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the M240i xDrive 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 (4.53 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 0.19 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
