Audi S e-tron GT vs Alfa Romeo Giulia Quadrifoglio: which is truly faster?

Off the line, the S e-tron GT hits 100 km/h in 3.36 s versus 3.94 s for the Giulia Quadrifoglio. The instant torque of 640 Nm from the electric motor makes the difference. At this point, the S e-tron GT leads by 0.59 s and sits roughly 11 m ahead.

At 200 metres, the S e-tron GT is doing 158 km/h against 164 km/h for the Giulia Quadrifoglio. The gap is 0.40 s. The challenger starts to claw back ground.

At 400 metres standing start, the S e-tron GT crosses the line in 11.50 s versus 11.74 s. The 0.23 s gap represents roughly 13 m of track - two to three car lengths.

Past 400 metres, the situation changes. The S e-tron GT maxes out at 245 km/h while the Giulia Quadrifoglio keeps accelerating towards 307 km/h. At 600 metres, the gap has dropped to 0.07 s.

Around 705 metres, both vehicles are level. This is the inversion point: the Giulia Quadrifoglio overcomes its launch deficit thanks to a 62 km/h higher top speed.

At 1,000 metres, the Giulia Quadrifoglio finishes in 20.93 s versus 21.11 s. The 0.18 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the S e-tron GT is capped at 245 km/h, the Giulia Quadrifoglio at 307 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 5.51 seconds. The 0.59 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
