The start: 0 to 100 km/h

Off the line, the SQ8 SUV hits 100 km/h in 4.03 s versus 8.50 s for the X4 xDrive20i. At this point, the SQ8 SUV leads by 4.47 s and sits roughly 21 m ahead.

From 100 km/h to 400 metres

At 200 metres, the SQ8 SUV is doing 154 km/h against 112 km/h for the X4 xDrive20i. The gap is 2.55 s. The challenger starts to claw back ground.

At 400 metres standing start, the SQ8 SUV crosses the line in 12.11 s versus 16.22 s. The 4.10 s gap represents roughly 148 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the SQ8 SUV continues to build its lead. At 600 metres, it runs at 213 km/h versus 155 km/h. At 1,000 metres, the SQ8 SUV finishes in 21.98 s versus 29.79 s, with a 7.82 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the SQ8 SUV is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X4 xDrive20i at 215 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 (4.42 kg/hp vs 9.48 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.15 seconds. The 4.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
