The start: 0 to 100 km/h

Off the line, the S3 Sedan hits 100 km/h in 4.63 s versus 6.27 s for the 128ti. At this point, the S3 Sedan leads by 1.64 s and sits roughly 21 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S3 Sedan is doing 138 km/h against 132 km/h for the 128ti. The gap is 1.10 s. The challenger starts to claw back ground.

At 400 metres standing start, the S3 Sedan crosses the line in 13.08 s versus 14.44 s. The 1.36 s gap represents roughly 61 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S3 Sedan continues to build its lead. At 600 metres, it runs at 198 km/h versus 184 km/h. At 1,000 metres, the S3 Sedan finishes in 23.69 s versus 25.86 s, with a 2.18 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 S3 Sedan and the 128ti 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 5.45 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.33 seconds. The 1.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
