Off the line, the 125d hits 100 km/h in 6.48 s versus 7.22 s for the A3 Sportback TFSI e 150 kW. Despite lacking instant torque, 224 hp of power compensates. At this point, the 125d leads by 0.74 s and sits roughly 10 m ahead.
At 200 metres, the 125d is doing 130 km/h against 124 km/h for the A3 Sportback TFSI e 150 kW. The gap is 0.51 s. The challenger starts to claw back ground.
At 400 metres standing start, the 125d crosses the line in 14.67 s versus 15.38 s. The 0.70 s gap represents roughly 30 m of track - a gap visible to the naked eye.
Past 400 metres, the 125d continues to build its lead. At 600 metres, it runs at 180 km/h versus 174 km/h. At 1,000 metres, the 125d finishes in 26.39 s versus 27.44 s, with a 1.04 s lead.
Both rivals are electronically governed, but not at the same level: the 125d is capped at 240 km/h, the A3 Sportback TFSI e 150 kW at 225 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.16 seconds. The 0.74 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 125d F20LCI wins (6,48 s vs 7,22 s).
125d F20LCI goes from 0 to 100 km/h in 6,48 seconds (calibrated simulation).
