The start: 0 to 100 km/h

Off the line, the RS Q8 SUV hits 100 km/h in 3.66 s versus 4.30 s for the Model X Long Range. Despite lacking instant torque, 640 hp of power compensates. At this point, the RS Q8 SUV leads by 0.64 s and sits roughly 10 m ahead.

From 100 km/h to 400 metres

At 200 metres, the RS Q8 SUV is doing 161 km/h against 158 km/h for the Model X Long Range. The gap is 0.49 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 12.14 s. The 0.56 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 RS Q8 SUV continues to build its lead. At 600 metres, it runs at 223 km/h versus 221 km/h. At 1,000 metres, the RS Q8 SUV finishes in 21.01 s versus 21.65 s, with a 0.64 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the Model X Long Range and the RS Q8 SUV are governed to 249 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

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 5.92 seconds. The 0.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
