Off the line, the Q8 SUV hits 100 km/h in 5.57 s versus 6.04 s for the iX xDrive40. Despite lacking instant torque, 340 hp of power compensates. At this point, the Q8 SUV leads by 0.47 s and sits roughly 5 m ahead.
At 200 metres, the Q8 SUV is doing 131 km/h against 127 km/h for the iX xDrive40. The gap is 0.29 s. The challenger starts to claw back ground.
At 400 metres standing start, the Q8 SUV crosses the line in 13.90 s versus 14.36 s. The 0.47 s gap represents roughly 20 m of track - two to three car lengths.
Past 400 metres, the Q8 SUV continues to build its lead. At 600 metres, it runs at 181 km/h versus 175 km/h. At 1,000 metres, the Q8 SUV finishes in 25.53 s versus 26.37 s, with a 0.84 s lead.
Both rivals are electronically governed, but not at the same level: the Q8 SUV is capped at 250 (i.e. 155 mph - industry threshold) km/h, the iX xDrive40 at 200 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 9.74 seconds. The 0.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Q8 SUV wins (5,57 s vs 6,04 s).
