296 GTB vs Bmw M850i xDrive Gran Coupe: 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 3.97 s for the Bmw M850i xDrive Gran Coupe. At this point, the 296 GTB leads by 1.03 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 158 km/h for the Bmw M850i xDrive Gran Coupe. The gap is 1.02 s. The gap remains stable from the start.
At 400 metres standing start, the 296 GTB crosses the line in 10.30 s versus 11.88 s. The 1.58 s gap represents roughly 83 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 221 km/h. At 1,000 metres, the 296 GTB finishes in 18.57 s versus 21.37 s, with a 2.80 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw M850i xDrive Gran Coupe 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 3.79 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.71 seconds. The 1.03 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 Gran Coupe to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
