Bmw 840i xDrive Convertible 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 Convertible hits 100 km/h in 5.30 s versus 5.68 s for the Focus ST 280. At this point, the Bmw 840i xDrive Convertible leads by 0.38 s and sits roughly 11 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 840i xDrive Convertible is doing 136 km/h against 139 km/h for the Focus ST 280. The gap is 0.34 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 840i xDrive Convertible crosses the line in 13.56 s versus 13.79 s. The 0.23 s gap represents roughly 11 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the gap narrows. The Bmw 840i xDrive Convertible maxes out at 250 km/h while the Focus ST 280 keeps accelerating towards 264 km/h. At 600 metres, the gap is down to 0.15 s from 0.23 s at 400 metres.
At 1,000 metres, the Bmw 840i xDrive Convertible finishes in 24.59 s versus 24.63 s, with just 0.05 s to spare. The Focus ST 280 fails to fully close the launch gap.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw 840i xDrive Convertible 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 (5.75 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 0.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 840i xDrive Convertible 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.
