Off the line, the X7 M50d hits 100 km/h in 5.49 s versus 7.43 s for the 223d xDrive Active Tourer. At this point, the X7 M50d leads by 1.94 s and sits roughly 20 m ahead.
At 200 metres, the X7 M50d is doing 132 km/h against 121 km/h for the 223d xDrive Active Tourer. The gap is 1.21 s. The challenger starts to claw back ground.
At 400 metres standing start, the X7 M50d crosses the line in 13.82 s versus 15.43 s. The 1.62 s gap represents roughly 66 m of track - a gap visible to the naked eye.
Past 400 metres, the X7 M50d continues to build its lead. At 600 metres, it runs at 184 km/h versus 171 km/h. At 1,000 metres, the X7 M50d finishes in 25.28 s versus 27.75 s, with a 2.48 s lead.
Both rivals are electronically governed, but not at the same level: the X7 M50d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 223d xDrive Active Tourer at 233 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 (6.15 kg/hp vs 7.84 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.39 seconds. The 1.94 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X7 M50d G07 wins (5,49 s vs 7,43 s).
X7 M50d G07 goes from 0 to 100 km/h in 5,49 seconds (calibrated simulation).
