Bmw 840i xDrive vs Focus ST 280: chronicle of a drag race at 264 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 840i xDrive hits 100 km/h in 4.81 s versus 5.68 s for the Focus ST 280. At this point, the Bmw 840i xDrive leads by 0.87 s and sits roughly 14 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 840i xDrive is doing 142 km/h against 139 km/h for the Focus ST 280. The gap is 0.66 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840i xDrive crosses the line in 13.05 s versus 13.79 s. The 0.74 s gap represents roughly 35 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 840i xDrive continues to build its lead. At 600 metres, it runs at 198 km/h versus 194 km/h. At 1,000 metres, the Bmw 840i xDrive finishes in 23.65 s versus 24.63 s, with a 0.99 s lead. Both vehicles have similar top speeds (250 vs 264 km/h), preventing any comeback.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw 840i 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 (5.39 kg/hp vs 5.11 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.27 seconds. The 0.87 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 840i xDrive has a clear edge over the Ford Focus ST 280 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
