Off the line, the S5 Avant hits 100 km/h in 4.53 s versus 5.74 s for the Bmw X4 xDrive30d. At this point, the S5 Avant leads by 1.21 s and sits roughly 11 m ahead.
At 200 metres, the S5 Avant is doing 142 km/h against 130 km/h for the Bmw X4 xDrive30d. The gap is 0.80 s. The challenger starts to claw back ground.
At 400 metres standing start, the S5 Avant crosses the line in 12.83 s versus 14.07 s. The 1.23 s gap represents roughly 54 m of track - a gap visible to the naked eye.
Past 400 metres, the S5 Avant continues to build its lead. At 600 metres, it runs at 197 km/h versus 179 km/h. At 1,000 metres, the S5 Avant finishes in 23.49 s versus 25.82 s, with a 2.33 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 245 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the S5 Avant is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw X4 xDrive30d at 245 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 (5.35 kg/hp vs 6.75 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.17 seconds. The 1.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S5 Avant wins (4,53 s vs 5,74 s).
S5 Avant goes from 0 to 100 km/h in 4,53 seconds (calibrated simulation).
