The start: 0 to 100 km/h

Off the line, the Q8 SUV hits 100 km/h in 5.97 s versus 6.82 s for the G6. Despite lacking instant torque, 286 hp of power compensates. At this point, the Q8 SUV leads by 0.85 s and sits roughly 20 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Q8 SUV is doing 125 km/h against 126 km/h for the G6. The gap is 0.75 s. The gap remains stable from the start.

At 400 metres standing start, the Q8 SUV crosses the line in 14.25 s versus 14.96 s. The 0.71 s gap represents roughly 30 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The G6 maxes out at 200 km/h while the Q8 SUV keeps accelerating towards 241 km/h. At 600 metres, the gap has dropped to 0.64 s.

At 1,000 metres, the Q8 SUV finishes in 26.36 s versus 26.81 s, with just 0.45 s to spare. The G6 fails to fully close the launch gap.

What the numbers don’t tell you

The Q8 SUV features all-wheel drive (AWD) against the G6’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the G6 is capped at 200 km/h, the Q8 SUV at 241 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 10.49 seconds. The 0.85 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
