BMW X4 M Competition G02 vs Audi Q6 SUV e-tron: which is truly faster?

Off the line, the Bmw X4 M Competition hits 100 km/h in 4.13 s versus 6.82 s for the Q6 SUV e-tron. Despite lacking instant torque, 510 hp of power compensates. At this point, the Bmw X4 M Competition leads by 2.69 s and sits roughly 26 m ahead.

At 200 metres, the Bmw X4 M Competition is doing 151 km/h against 128 km/h for the Q6 SUV e-tron. The gap is 2.00 s. The challenger starts to claw back ground.

At 400 metres standing start, the Bmw X4 M Competition crosses the line in 12.22 s versus 15.00 s. The 2.79 s gap represents roughly 116 m of track - a gap visible to the naked eye.

Past 400 metres, the Bmw X4 M Competition continues to build its lead. At 600 metres, it runs at 207 km/h versus 174 km/h. At 1,000 metres, the Bmw X4 M Competition finishes in 22.35 s versus 27.06 s, with a 4.71 s lead.

The Bmw X4 M Competition features all-wheel drive (AWD) against the Q6 SUV e-tron’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 Bmw X4 M Competition is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Q6 SUV e-tron at 210 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 10.26 seconds. The 2.69 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
