BMW X2 xDrive25e F39 vs Audi Q4 40 e-tron 150 kW: which is truly faster?

Off the line, the X2 xDrive25e hits 100 km/h in 6.74 s versus 8.62 s for the Q4 40 e-tron 150 kW. At this point, the X2 xDrive25e leads by 1.88 s and sits roughly 27 m ahead.

At 200 metres, the X2 xDrive25e is doing 122 km/h against 115 km/h for the Q4 40 e-tron 150 kW. The gap is 1.27 s. The challenger starts to claw back ground.

At 400 metres standing start, the X2 xDrive25e crosses the line in 14.89 s versus 16.48 s. The 1.59 s gap represents roughly 61 m of track - a gap visible to the naked eye.

Past 400 metres, the X2 xDrive25e continues to build its lead. At 600 metres, it runs at 169 km/h versus 157 km/h. At 1,000 metres, the X2 xDrive25e finishes in 27.32 s versus 30.31 s, with a 2.99 s lead.

The X2 xDrive25e features all-wheel drive (AWD) against the Q4 40 e-tron 150 kW’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 X2 xDrive25e is capped at 195 km/h, the Q4 40 e-tron 150 kW at 160 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.

With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (7.86 kg/hp vs 10.57 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.70 seconds. The 1.88 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
