Off the line, the X6 M50d hits 100 km/h in 5.29 s versus 6.63 s for the 225i xDrive Active Tourer. At this point, the X6 M50d leads by 1.34 s and sits roughly 14 m ahead.
At 200 metres, the X6 M50d is doing 135 km/h against 126 km/h for the 225i xDrive Active Tourer. The gap is 0.86 s. The challenger starts to claw back ground.
At 400 metres standing start, the X6 M50d crosses the line in 13.62 s versus 14.83 s. The 1.21 s gap represents roughly 51 m of track - a gap visible to the naked eye.
Past 400 metres, the X6 M50d continues to build its lead. At 600 metres, it runs at 187 km/h versus 174 km/h. At 1,000 metres, the X6 M50d finishes in 24.91 s versus 26.93 s, with a 2.02 s lead.
Both rivals are electronically governed, but not at the same level: the X6 M50d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 225i xDrive Active Tourer at 235 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 (5.73 kg/hp vs 6.58 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.33 seconds. The 1.34 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X6 M50d F16 wins (5,29 s vs 6,63 s).
X6 M50d F16 goes from 0 to 100 km/h in 5,29 seconds (calibrated simulation).
