BMW i5 xDrive40 G60 vs BMW 740Ld xDrive G11: which is truly faster?

Off the line, the 740Ld xDrive hits 100 km/h in 5.01 s versus 5.30 s for the i5 xDrive40. Despite lacking instant torque, 340 hp of power compensates. At this point, the 740Ld xDrive leads by 0.29 s and sits roughly 7 m ahead.

At 200 metres, the 740Ld xDrive is doing 137 km/h against 137 km/h for the i5 xDrive40. The gap is 0.26 s. The gap remains stable from the start.

At 400 metres standing start, the 740Ld xDrive crosses the line in 13.31 s versus 13.59 s. The 0.28 s gap represents roughly 13 m of track - two to three car lengths.

Past 400 metres, the 740Ld xDrive continues to build its lead. At 600 metres, it runs at 192 km/h versus 191 km/h. At 1,000 metres, the 740Ld xDrive finishes in 24.26 s versus 24.58 s, with a 0.31 s lead.

The 740Ld xDrive features all-wheel drive (AWD) against the i5 xDrive40’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 i5 xDrive40 is capped at 215 km/h, the 740Ld xDrive at 250 (i.e. 155 mph - industry threshold) 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 8.09 seconds. The 0.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
