Off the line, the SQ2 hits 100 km/h in 4.94 s versus 5.49 s for the X7 M50d. At this point, the SQ2 leads by 0.55 s and sits roughly 6 m ahead.
At 200 metres, the SQ2 is doing 133 km/h against 132 km/h for the X7 M50d. The gap is 0.26 s. The challenger starts to claw back ground.
At 400 metres standing start, the SQ2 crosses the line in 13.47 s versus 13.82 s. The 0.35 s gap represents roughly 16 m of track - two to three car lengths.
Past 400 metres, the SQ2 continues to build its lead. At 600 metres, it runs at 190 km/h versus 184 km/h. At 1,000 metres, the SQ2 finishes in 24.55 s versus 25.28 s, with a 0.73 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 257 km/h), preventing any comeback.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the X7 M50d never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (6.15 kg/hp vs 5.12 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.69 seconds. The 0.55 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, SQ2 wins (4,94 s vs 5,49 s).
X7 M50d G07 goes from 0 to 100 km/h in 5,49 seconds (calibrated simulation).
