Bmw 640i xDrive Gran Turismo vs Giulia Veloce: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Giulia Veloce hits 100 km/h in 5.26 s versus 5.37 s for the Bmw 640i xDrive Gran Turismo. At this point, the Giulia Veloce leads by 0.11 s and sits roughly 1 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Giulia Veloce is doing 135 km/h against 135 km/h for the Bmw 640i xDrive Gran Turismo. The gap is 0.08 s. The gap remains stable from the start.
At 400 metres standing start, the Giulia Veloce crosses the line in 13.56 s versus 13.61 s. The 0.05 s gap represents roughly 2 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Giulia Veloce maxes out at 240 km/h while the Bmw 640i xDrive Gran Turismo keeps accelerating towards 250 km/h. At 600 metres, the gap has dropped to 0.01 s.
Around 588 metres, both vehicles are level. This is the inversion point: the Bmw 640i xDrive Gran Turismo overcomes its launch deficit thanks to a 10 km/h higher top speed.
At 1,000 metres, the Bmw 640i xDrive Gran Turismo finishes in 24.70 s versus 24.89 s. The 0.19 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 Bmw 640i xDrive Gran Turismo is capped at 250 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.74 kg/hp vs 5.68 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.25 seconds. The 0.11 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Alfa Romeo Giulia Veloce is slightly faster than the Bmw 640i xDrive Gran Turismo to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
