CONFIDENCE 94%The Taycan GTS reaches 100 km/h first (3.65 s vs 3.93 s), but the Giulia Quadrifoglio is ahead at every metre of the race. Explanation: the Giulia Quadrifoglio accelerates harder at low speed and builds a distance gap before either car hits 100 km/h.
Why this result?
The Porsche Taycan GTS is faster at 0-100 km/h, but the Alfa Romeo Giulia Quadrifoglio compensates at high speed thanks to higher peak power or top speed. At 400 m, Alfa Romeo Giulia Quadrifoglio leads by 0.02 s.

Taycan GTS vs Giulia Quadrifoglio: chronicle of a drag race at 307 km/h
The launch: 0 to 100 km/h
Off the line, the Taycan GTS hits 100 km/h in 3.65 s versus 3.93 s for the Giulia Quadrifoglio. The instant torque of 850 Nm from the electric motor makes the difference. At this point, the Taycan GTS leads by 0.28 s and sits roughly 7 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Taycan GTS is doing 156 km/h against 164 km/h for the Giulia Quadrifoglio. The gap is 0.17 s. The challenger starts to claw back ground.
At 400 metres standing start, the Giulia Quadrifoglio crosses the line in 11.73 s versus 11.75 s. The 0.02 s gap represents roughly 1 m of track
Beyond 400 metres: top speed comes into play
Past 400 metres, the Giulia Quadrifoglio continues to build its lead. At 600 metres, it runs at 228 km/h versus 219 km/h. At 1,000 metres, the Giulia Quadrifoglio finishes in 20.92 s versus 21.32 s, with a 0.40 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Taycan GTS is capped at 249 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 5.53 seconds. The 0.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Taycan GTS is slightly faster than the Alfa Romeo Giulia Quadrifoglio to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
