The start: 0 to 100 km/h

Off the line, the RS Q8 SUV hits 100 km/h in 3.66 s versus 7.97 s for the Bmw X4 xDrive20d. At this point, the RS Q8 SUV leads by 4.31 s and sits roughly 17 m ahead.

From 100 km/h to 400 metres

At 200 metres, the RS Q8 SUV is doing 161 km/h against 113 km/h for the Bmw X4 xDrive20d. The gap is 2.52 s. The challenger starts to claw back ground.

At 400 metres standing start, the RS Q8 SUV crosses the line in 11.58 s versus 15.80 s. The 4.21 s gap represents roughly 153 m of track — a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the RS Q8 SUV continues to build its lead. At 600 metres, it runs at 223 km/h versus 156 km/h. At 1,000 metres, the RS Q8 SUV finishes in 21.01 s versus 29.28 s, with a 8.27 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the RS Q8 SUV is capped at 250 (i.e. 155 mph — industry threshold) km/h, the Bmw X4 xDrive20d at 213 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 (3.55 kg/hp vs 9.74 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.55 seconds. The 4.31 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
