The start: 0 to 100 km/h

Off the line, the Giulia Veloce hits 100 km/h in 5.26 s versus 5.83 s for the E 300 d. At this point, the Giulia Veloce leads by 0.58 s and sits roughly 2 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Giulia Veloce is doing 135 km/h against 130 km/h for the E 300 d. The gap is 0.29 s. The challenger starts to claw back ground.

At 400 metres standing start, the Giulia Veloce crosses the line in 13.56 s versus 14.03 s. The 0.47 s gap represents roughly 21 m of track - two to three car lengths.

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 183 km/h. At 1,000 metres, the Giulia Veloce finishes in 24.89 s versus 25.49 s, with a 0.60 s lead. Both vehicles have similar top speeds (240 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Giulia Veloce is capped at 240 km/h, the E 300 d at 250 (i.e. 155 mph - industry threshold) 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.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.68 kg/hp vs 7.15 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.16 seconds. The 0.58 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
