BMW X1 xDrive25e F48 vs BMW X2 sDrive18d F39: which is truly faster?

Off the line, the X1 xDrive25e hits 100 km/h in 6.78 s versus 9.16 s for the X2 sDrive18d. The instant torque of 385 Nm from the electric motor makes the difference. At this point, the X1 xDrive25e leads by 2.38 s and sits roughly 23 m ahead.

At 200 metres, the X1 xDrive25e is doing 122 km/h against 110 km/h for the X2 sDrive18d. The gap is 1.25 s. The challenger starts to claw back ground.

At 400 metres standing start, the X1 xDrive25e crosses the line in 14.92 s versus 16.72 s. The 1.80 s gap represents roughly 66 m of track - a gap visible to the naked eye.

Past 400 metres, the X1 xDrive25e continues to build its lead. At 600 metres, it runs at 168 km/h versus 152 km/h. At 1,000 metres, the X1 xDrive25e finishes in 27.44 s versus 30.60 s, with a 3.16 s lead. Both vehicles have similar top speeds (193 vs 206 km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the X1 xDrive25e is capped at 193 km/h, the X2 sDrive18d at 207 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 15.20 seconds. The 2.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
