The start: 0 to 100 km/h

Off the line, the P7 hits 100 km/h in 4.22 s versus 5.26 s for the Giulia Veloce. The instant torque of 655 Nm from the electric motor makes the difference. At this point, the P7 leads by 1.04 s and sits roughly 10 m ahead.

From 100 km/h to 400 metres

At 200 metres, the P7 is doing 147 km/h against 135 km/h for the Giulia Veloce. The gap is 0.71 s. The challenger starts to claw back ground.

At 400 metres standing start, the P7 crosses the line in 12.54 s versus 13.56 s. The 1.01 s gap represents roughly 46 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. The P7 maxes out at 170 km/h while the Giulia Veloce keeps accelerating towards 240 km/h. At 600 metres, the gap has dropped to 0.86 s.

Around 906 metres, both vehicles are level. This is the inversion point: the Giulia Veloce overcomes its launch deficit thanks to a 70 km/h higher top speed.

At 1,000 metres, the Giulia Veloce finishes in 24.89 s versus 25.24 s. The 0.36 s delta shows an extremely tight race.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the P7 is capped at 170 km/h, the Giulia Veloce at 240 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 8.11 seconds. The 1.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
