BMW 750Ld xDrive G11 vs MG4 Long Range RWD: which is truly faster?

Off the line, the 750Ld xDrive hits 100 km/h in 4.63 s versus 6.73 s for the 4 Long Range RWD. Despite lacking instant torque, 400 hp of power compensates. At this point, the 750Ld xDrive leads by 2.10 s and sits roughly 23 m ahead.

At 200 metres, the 750Ld xDrive is doing 145 km/h against 129 km/h for the 4 Long Range RWD. The gap is 1.50 s. The challenger starts to claw back ground.

At 400 metres standing start, the 750Ld xDrive crosses the line in 12.84 s versus 14.92 s. The 2.08 s gap represents roughly 88 m of track - a gap visible to the naked eye.

Past 400 metres, the 750Ld xDrive continues to build its lead. At 600 metres, it runs at 203 km/h versus 176 km/h. At 1,000 metres, the 750Ld xDrive finishes in 23.18 s versus 27.23 s, with a 4.05 s lead.

The 750Ld xDrive features all-wheel drive (AWD) against the 4 Long Range RWD’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 750Ld xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 4 Long Range RWD at 180 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 10.07 seconds. The 2.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
