Off the line, the Bmw M135i xDrive hits 100 km/h in 4.78 s versus 4.94 s for the SQ2. Despite the faster sprint time, the SQ2 is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw M135i xDrive is doing 144 km/h against 133 km/h for the SQ2. The gap is 0.18 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M135i xDrive crosses the line in 13.00 s versus 13.47 s. The 0.47 s gap represents roughly 22 m of track - two to three car lengths.
Past 400 metres, the Bmw M135i xDrive continues to build its lead. At 600 metres, it runs at 199 km/h versus 190 km/h. At 1,000 metres, the Bmw M135i xDrive finishes in 23.59 s versus 24.55 s, with a 0.96 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 Bmw M135i xDrive 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 (4.98 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 0.16 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M135i xDrive F40 wins (4,78 s vs 4,94 s).
M135i xDrive F40 goes from 0 to 100 km/h in 4,78 seconds (calibrated simulation).
