The start: 0 to 100 km/h

Off the line, the S3 Sportback hits 100 km/h in 4.64 s versus 4.67 s for the M240i. The 0.03 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the M240i is doing 147 km/h against 139 km/h for the S3 Sportback. The gap is 0.09 s. The gap widens compared to the 0-100.

At 400 metres standing start, the M240i crosses the line in 12.78 s versus 13.08 s. The 0.31 s gap represents roughly 15 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M240i continues to build its lead. At 600 metres, it runs at 205 km/h versus 197 km/h. At 1,000 metres, the M240i finishes in 23.03 s versus 23.72 s, with a 0.68 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

On paper, the M240i combines 340 hp, 500 Nm and 1,525 kg - a clear theoretical edge over the S3 Sportback. Yet the S3 Sportback launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the S3 Sportback has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs - exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.

Both rivals share the same electronic speed cap: the M240i 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 (4.49 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 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
