The start: 0 to 100 km/h

Off the line, the 128ti hits 100 km/h in 6.22 s versus 9.82 s for the A3 Sedan. At this point, the 128ti leads by 3.60 s and sits roughly 19 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 128ti is doing 136 km/h against 108 km/h for the A3 Sedan. The gap is 1.69 s. The challenger starts to claw back ground.

At 400 metres standing start, the 128ti crosses the line in 14.31 s versus 17.21 s. The 2.90 s gap represents roughly 104 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 128ti continues to build its lead. At 600 metres, it runs at 190 km/h versus 151 km/h. At 1,000 metres, the 128ti finishes in 25.37 s versus 31.15 s, with a 5.77 s lead.

What the numbers don’t tell you

Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the 128ti never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.45 kg/hp vs 11.34 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.05 seconds. The 3.60 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
