DS4 PureTech 225 EAT8 vs Bmw 320d Steptronic: chronicle of a drag race at 245 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 320d Steptronic hits 100 km/h in 6.73 s versus 7.76 s for the DS4 PureTech 225 EAT8. At this point, the Bmw 320d Steptronic leads by 1.03 s and sits roughly 28 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 320d Steptronic is doing 121 km/h against 126 km/h for the DS4 PureTech 225 EAT8. The gap is 0.98 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 320d Steptronic crosses the line in 14.88 s versus 15.61 s. The 0.73 s gap represents roughly 32 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the gap narrows. The Bmw 320d Steptronic maxes out at 240 km/h while the DS4 PureTech 225 EAT8 keeps accelerating towards 245 km/h. At 600 metres, the gap is down to 0.48 s from 0.73 s at 400 metres.
At 1,000 metres, the Bmw 320d Steptronic finishes in 27.33 s versus 27.41 s, with just 0.08 s to spare. The DS4 PureTech 225 EAT8 fails to fully close the launch gap.
What the numbers don’t tell you
Electronically capped at 240 km/h, the Bmw 320d Steptronic 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 7.66 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.04 seconds. The 1.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 320d Steptronic 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.
