Audi Q6 Sportback e-tron vs BMW X4 xDrive25d G02: which is truly faster?

Off the line, the X4 xDrive25d hits 100 km/h in 6.90 s versus 7.52 s for the Q6 Sportback e-tron. Despite lacking instant torque, 231 hp of power compensates. At this point, the X4 xDrive25d leads by 0.62 s and sits roughly 11 m ahead.

At 200 metres, the X4 xDrive25d is doing 121 km/h against 120 km/h for the Q6 Sportback e-tron. The gap is 0.46 s. The challenger starts to claw back ground.

At 400 metres standing start, the X4 xDrive25d crosses the line in 15.07 s versus 15.60 s. The 0.54 s gap represents roughly 22 m of track - two to three car lengths.

Past 400 metres, the X4 xDrive25d continues to build its lead. At 600 metres, it runs at 167 km/h versus 164 km/h. At 1,000 metres, the X4 xDrive25d finishes in 27.65 s versus 28.40 s, with a 0.75 s lead.

The X4 xDrive25d features all-wheel drive (AWD) against the Q6 Sportback 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 Q6 Sportback e-tron is capped at 210 km/h, the X4 xDrive25d at 230 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 11.98 seconds. The 0.62 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
