BMW X7 xDrive30d G07 vs BMW X1 xDrive25e F48: which is truly faster?

Off the line, the X1 xDrive25e hits 100 km/h in 6.78 s versus 6.94 s for the X7 xDrive30d. The instant torque of 385 Nm from the electric motor makes the difference. Despite the faster sprint time, the X7 xDrive30d is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

At 200 metres, the X7 xDrive30d is doing 119 km/h against 122 km/h for the X1 xDrive25e. The gap is 0.01 s. The challenger starts to claw back ground.

At 400 metres standing start, the X1 xDrive25e crosses the line in 14.92 s versus 15.04 s. The 0.12 s gap represents roughly 5 m of track - barely a car length.

Past 400 metres, the X1 xDrive25e continues to build its lead. At 600 metres, it runs at 168 km/h versus 164 km/h. At 1,000 metres, the X1 xDrive25e finishes in 27.44 s versus 27.89 s, with a 0.46 s lead. Despite a higher top speed (227 km/h), the X7 xDrive30d never recovers its launch deficit.

Both rivals are electronically governed, but not at the same level: the X7 xDrive30d is capped at 227 km/h, the X1 xDrive25e at 193 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 11.64 seconds. The 0.16 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
