296 GTB vs Bmw M850i xDrive: chronicle of a drag race at 338 km/h
The launch: 0 to 100 km/h
Off the line, the 296 GTB hits 100 km/h in 2.94 s versus 3.83 s for the Bmw M850i xDrive. At this point, the 296 GTB leads by 0.89 s and sits roughly 9 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 296 GTB is doing 184 km/h against 161 km/h for the Bmw M850i xDrive. The gap is 0.93 s. The gap remains stable from the start.
At 400 metres standing start, the 296 GTB crosses the line in 10.30 s versus 11.74 s. The 1.43 s gap represents roughly 77 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 296 GTB continues to build its lead. At 600 metres, it runs at 255 km/h versus 225 km/h. At 1,000 metres, the 296 GTB finishes in 18.57 s versus 21.08 s, with a 2.51 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw M850i xDrive never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (2.37 kg/hp vs 3.64 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.51 seconds. The 0.89 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Ferrari 296 GTB has a clear edge over the Bmw M850i xDrive to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
