The start: 0 to 100 km/h

Off the line, the X5 M50i hits 100 km/h in 4.39 s versus 4.94 s for the SQ2. At this point, the X5 M50i leads by 0.56 s and sits roughly 2 m ahead.

From 100 km/h to 400 metres

At 200 metres, the X5 M50i is doing 150 km/h against 133 km/h for the SQ2. The gap is 0.50 s. The gap remains stable from the start.

At 400 metres standing start, the X5 M50i crosses the line in 12.48 s versus 13.47 s. The 0.99 s gap represents roughly 46 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the X5 M50i continues to build its lead. At 600 metres, it runs at 208 km/h versus 190 km/h. At 1,000 metres, the X5 M50i finishes in 22.56 s versus 24.55 s, with a 1.99 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 257 km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the X5 M50i 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 (4.26 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 0.56 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
