Bmw 420i Gran Coupe vs DS3 Crossback PureTech 155 EAT8: chronicle of a drag race at 236 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 420i Gran Coupe hits 100 km/h in 7.31 s versus 9.00 s for the DS3 Crossback PureTech 155 EAT8. At this point, the Bmw 420i Gran Coupe leads by 1.69 s and sits roughly 35 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 420i Gran Coupe is doing 117 km/h against 118 km/h for the DS3 Crossback PureTech 155 EAT8. The gap is 1.42 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 420i Gran Coupe crosses the line in 15.34 s versus 16.76 s. The 1.41 s gap represents roughly 56 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 420i Gran Coupe continues to build its lead. At 600 metres, it runs at 166 km/h versus 164 km/h. At 1,000 metres, the Bmw 420i Gran Coupe finishes in 28.04 s versus 29.59 s, with a 1.55 s lead.
What the numbers don’t tell you
Electronically capped at 236 km/h, the Bmw 420i 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 (8.51 kg/hp vs 7.88 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.40 seconds. The 1.69 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 420i Gran Coupe has a clear edge over the DS DS3 Crossback PureTech 155 EAT8 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
