BMW X5 M Competition G05 vs Audi e-tron GT quattro: which is truly faster?

Off the line, the X5 M Competition hits 100 km/h in 3.83 s versus 4.14 s for the e-tron GT quattro. Despite lacking instant torque, 625 hp of power compensates. At this point, the X5 M Competition leads by 0.31 s and sits roughly 4 m ahead.

At 200 metres, the X5 M Competition is doing 155 km/h against 149 km/h for the e-tron GT quattro. The gap is 0.27 s. The gap remains stable from the start.

At 400 metres standing start, the X5 M Competition crosses the line in 11.94 s versus 12.36 s. The 0.42 s gap represents roughly 21 m of track - two to three car lengths.

Past 400 metres, the X5 M Competition continues to build its lead. At 600 metres, it runs at 215 km/h versus 208 km/h. At 1,000 metres, the X5 M Competition finishes in 21.80 s versus 22.46 s, with a 0.66 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 245 km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the X5 M Competition is capped at 250 (i.e. 155 mph - industry threshold) km/h, the e-tron GT quattro at 245 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 6.28 seconds. The 0.31 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
