DS4 PureTech 225 EAT8 vs Bmw 520d: chronicle of a drag race at 245 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 520d hits 100 km/h in 7.21 s versus 7.76 s for the DS4 PureTech 225 EAT8. At this point, the Bmw 520d leads by 0.55 s and sits roughly 25 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 520d is doing 118 km/h against 126 km/h for the DS4 PureTech 225 EAT8. The gap is 0.77 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 520d crosses the line in 15.24 s versus 15.61 s. The 0.36 s gap represents roughly 16 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Bmw 520d maxes out at 235 km/h while the DS4 PureTech 225 EAT8 keeps accelerating towards 245 km/h. At 600 metres, the gap has dropped to 0.02 s.
Around 589 metres, both vehicles are level. This is the inversion point: the DS4 PureTech 225 EAT8 overcomes its launch deficit thanks to a 10 km/h higher top speed.
At 1,000 metres, the DS4 PureTech 225 EAT8 finishes in 27.41 s versus 28.10 s. The 0.69 s delta in favour of the DS4 PureTech 225 EAT8 shows that top speed makes a clear difference.
What the numbers don’t tell you
Electronically capped at 235 km/h, the Bmw 520d 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 (6.49 kg/hp vs 8.68 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.95 seconds. The 0.55 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 520d has a clear edge over the DS DS4 PureTech 225 EAT8 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
