The start: 0 to 100 km/h

Off the line, the 740Le xDrive iPerformance hits 100 km/h in 5.32 s versus 5.74 s for the X4 xDrive30d. The instant torque of 400 Nm from the electric motor makes the difference. At this point, the 740Le xDrive iPerformance leads by 0.42 s and sits roughly 7 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 740Le xDrive iPerformance is doing 134 km/h against 130 km/h for the X4 xDrive30d. The gap is 0.35 s. The gap remains stable from the start.

At 400 metres standing start, the 740Le xDrive iPerformance crosses the line in 13.54 s versus 14.07 s. The 0.53 s gap represents roughly 23 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 740Le xDrive iPerformance continues to build its lead. At 600 metres, it runs at 188 km/h versus 179 km/h. At 1,000 metres, the 740Le xDrive iPerformance finishes in 24.72 s versus 25.82 s, with a 1.09 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 245 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 740Le xDrive iPerformance is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X4 xDrive30d at 245 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 9.17 seconds. The 0.42 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
