The start: 0 to 100 km/h

Off the line, the Giulia Veloce hits 100 km/h in 5.26 s versus 7.03 s for the 320d. At this point, the Giulia Veloce leads by 1.78 s and sits roughly 18 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Giulia Veloce is doing 135 km/h against 123 km/h for the 320d. The gap is 1.14 s. The challenger starts to claw back ground.

At 400 metres standing start, the Giulia Veloce crosses the line in 13.56 s versus 15.13 s. The 1.57 s gap represents roughly 65 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Giulia Veloce continues to build its lead. At 600 metres, it runs at 186 km/h versus 173 km/h. At 1,000 metres, the Giulia Veloce finishes in 24.89 s versus 27.23 s, with a 2.35 s lead. Both vehicles have similar top speeds (240 vs 240 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the Giulia Veloce and the 320d are governed to 240 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.68 kg/hp vs 7.63 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.96 seconds. The 1.78 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
