Off the line, the M850i xDrive Gran Coupe hits 100 km/h in 3.93 s versus 4.94 s for the SQ2. At this point, the M850i xDrive Gran Coupe leads by 1.01 s and sits roughly 5 m ahead.
At 200 metres, the M850i xDrive Gran Coupe is doing 159 km/h against 133 km/h for the SQ2. The gap is 0.87 s. The challenger starts to claw back ground.
At 400 metres standing start, the M850i xDrive Gran Coupe crosses the line in 11.88 s versus 13.47 s. The 1.59 s gap represents roughly 72 m of track - a gap visible to the naked eye.
Past 400 metres, the M850i xDrive Gran Coupe continues to build its lead. At 600 metres, it runs at 222 km/h versus 190 km/h. At 1,000 metres, the M850i xDrive Gran Coupe finishes in 21.34 s versus 24.55 s, with a 3.21 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 M850i xDrive Gran Coupe 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 (3.79 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 8.36 seconds. The 1.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M850i xDrive Gran Coupe G15 wins (3,93 s vs 4,94 s).
M850i xDrive Gran Coupe G15 goes from 0 to 100 km/h in 3,93 seconds (calibrated simulation).
