Bmw 318i Sedan vs Astra L 1.2 DI Turbo 130 8AT: chronicle of a drag race at 223 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 318i Sedan hits 100 km/h in 8.33 s versus 10.36 s for the Astra L 1.2 DI Turbo 130 8AT. At this point, the Bmw 318i Sedan leads by 2.03 s and sits roughly 38 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 318i Sedan is doing 113 km/h against 110 km/h for the Astra L 1.2 DI Turbo 130 8AT. The gap is 1.58 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 318i Sedan crosses the line in 16.06 s versus 17.77 s. The 1.70 s gap represents roughly 63 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 318i Sedan continues to build its lead. At 600 metres, it runs at 157 km/h versus 154 km/h. At 1,000 metres, the Bmw 318i Sedan finishes in 29.44 s versus 31.43 s, with a 1.99 s lead.
What the numbers don’t tell you
Electronically capped at 223 km/h, the Bmw 318i Sedan 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 (9.55 kg/hp vs 9.69 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.96 seconds. The 2.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 318i Sedan has a clear edge over the Opel Astra L 1.2 DI Turbo 130 8AT to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
