Off the line, the 318i hits 100 km/h in 8.33 s versus 9.98 s for the A5 Sedan. At this point, the 318i leads by 1.65 s and sits roughly 22 m ahead.
At 200 metres, the 318i is doing 113 km/h against 108 km/h for the A5 Sedan. The gap is 0.97 s. The challenger starts to claw back ground.
At 400 metres standing start, the 318i crosses the line in 16.06 s versus 17.30 s. The 1.23 s gap represents roughly 45 m of track - a gap visible to the naked eye.
Past 400 metres, the 318i continues to build its lead. At 600 metres, it runs at 157 km/h versus 150 km/h. At 1,000 metres, the 318i finishes in 29.44 s versus 31.28 s, with a 1.84 s lead. Both vehicles have similar top speeds (223 vs 216 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 318i is capped at 223 km/h, the A5 Sedan at 216 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (9.55 kg/hp vs 11.30 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.30 seconds. The 1.65 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 318i G20 wins (8,33 s vs 9,98 s).
318i G20 goes from 0 to 100 km/h in 8,33 seconds (calibrated simulation).
