Off the line, the X1 sDrive20i hits 100 km/h in 7.52 s versus 7.79 s for the A5 Sedan. The 0.27 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the X1 sDrive20i is doing 121 km/h against 117 km/h for the A5 Sedan. The gap is 0.09 s. The challenger starts to claw back ground.
At 400 metres standing start, the X1 sDrive20i crosses the line in 15.51 s versus 15.74 s. The 0.22 s gap represents roughly 9 m of track - barely a car length.
Past 400 metres, the X1 sDrive20i continues to build its lead. At 600 metres, it runs at 167 km/h versus 162 km/h. At 1,000 metres, the X1 sDrive20i finishes in 28.07 s versus 28.62 s, with a 0.55 s lead. Despite a higher top speed (242 km/h), the A5 Sedan never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the A5 Sedan is capped at 242 km/h, the X1 sDrive20i at 226 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 (8.92 kg/hp vs 7.73 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.41 seconds. The 0.27 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X1 sDrive20i F48 wins (7,52 s vs 7,79 s).
A5 Sedan goes from 0 to 100 km/h in 7,79 seconds (calibrated simulation).
