Bmw M340d xDrive Touring vs Giulia Veloce: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M340d xDrive Touring hits 100 km/h in 4.60 s versus 5.26 s for the Giulia Veloce. At this point, the Bmw M340d xDrive Touring leads by 0.66 s and sits roughly 12 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M340d xDrive Touring is doing 138 km/h against 135 km/h for the Giulia Veloce. The gap is 0.52 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M340d xDrive Touring crosses the line in 12.92 s versus 13.56 s. The 0.63 s gap represents roughly 29 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M340d xDrive Touring continues to build its lead. At 600 metres, it runs at 193 km/h versus 186 km/h. At 1,000 metres, the Bmw M340d xDrive Touring finishes in 23.77 s versus 24.89 s, with a 1.12 s lead. Both vehicles have similar top speeds (250 vs 240 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw M340d xDrive Touring 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 (5.87 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 8.11 seconds. The 0.66 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M340d xDrive Touring has a clear edge over the Alfa Romeo Giulia Veloce to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
