508 PureTech 180 EAT8 vs Bmw 318i: chronicle of a drag race at 238 km/h
The launch: 0 to 100 km/h
Off the line, the 508 PureTech 180 EAT8 hits 100 km/h in 8.32 s versus 8.33 s for the Bmw 318i. The 0.01 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Bmw 318i is doing 113 km/h against 119 km/h for the 508 PureTech 180 EAT8. The gap is 0.44 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 318i crosses the line in 16.06 s versus 16.20 s. The 0.14 s gap represents roughly 6 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Bmw 318i maxes out at 223 km/h while the 508 PureTech 180 EAT8 keeps accelerating towards 238 km/h. At 600 metres, the gap has dropped to 0.14 s.
Around 498 metres, both vehicles are level. This is the inversion point: the 508 PureTech 180 EAT8 overcomes its launch deficit thanks to a 15 km/h higher top speed.
At 1,000 metres, the 508 PureTech 180 EAT8 finishes in 28.78 s versus 29.44 s. The 0.65 s delta in favour of the 508 PureTech 180 EAT8 shows that top speed makes a clear difference.
What the numbers don’t tell you
Electronically capped at 223 km/h, the Bmw 318i 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 (8.32 kg/hp vs 9.55 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.71 seconds. The 0.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Peugeot 508 PureTech 180 EAT8 is slightly faster than the Bmw 318i to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
