The start: 0 to 100 km/h

Off the line, the Q8 SUV hits 100 km/h in 4.93 s versus 7.97 s for the X4 xDrive20d. The instant torque of 700 Nm from the electric motor makes the difference. At this point, the Q8 SUV leads by 3.04 s and sits roughly 14 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Q8 SUV is doing 140 km/h against 113 km/h for the X4 xDrive20d. The gap is 1.50 s. The challenger starts to claw back ground.

At 400 metres standing start, the Q8 SUV crosses the line in 13.18 s versus 15.80 s. The 2.61 s gap represents roughly 97 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Q8 SUV continues to build its lead. At 600 metres, it runs at 195 km/h versus 156 km/h. At 1,000 metres, the Q8 SUV finishes in 23.96 s versus 29.28 s, with a 5.32 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Q8 SUV is capped at 240 km/h, the 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.55 seconds. The 3.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
