The start: 0 to 100 km/h

Off the line, the X6 M Competition hits 100 km/h in 3.83 s versus 5.74 s for the X4 xDrive30d. At this point, the X6 M Competition leads by 1.91 s and sits roughly 13 m ahead.

From 100 km/h to 400 metres

At 200 metres, the X6 M Competition is doing 155 km/h against 130 km/h for the X4 xDrive30d. The gap is 1.33 s. The challenger starts to claw back ground.

At 400 metres standing start, the X6 M Competition crosses the line in 11.93 s versus 14.07 s. The 2.14 s gap represents roughly 92 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the X6 M Competition continues to build its lead. At 600 metres, it runs at 215 km/h versus 179 km/h. At 1,000 metres, the X6 M Competition finishes in 21.75 s versus 25.82 s, with a 4.07 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 245 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the X6 M Competition is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X4 xDrive30d at 245 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 (3.71 kg/hp vs 6.75 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.17 seconds. The 1.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
