The start: 0 to 100 km/h

Off the line, the iX M60 hits 100 km/h in 3.72 s versus 3.94 s for the Giulia Quadrifoglio. The instant torque of 1,100 Nm from the electric motor makes the difference. At this point, the iX M60 leads by 0.23 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the iX M60 is doing 151 km/h against 164 km/h for the Giulia Quadrifoglio. The gap is 0.12 s. The challenger starts to claw back ground.

At 400 metres standing start, the Giulia Quadrifoglio crosses the line in 11.74 s versus 11.94 s. The 0.20 s gap represents roughly 10 m of track - two to three car lengths.

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 212 km/h. At 1,000 metres, the Giulia Quadrifoglio finishes in 20.93 s versus 21.84 s, with a 0.92 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the iX M60 is capped at 250 (i.e. 155 mph - industry threshold) 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 5.80 seconds. The 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
