The start: 0 to 100 km/h

Off the line, the Bmw 750Ld xDrive hits 100 km/h in 4.63 s versus 5.49 s for the Bmw 840i Gran Coupe. At this point, the Bmw 750Ld xDrive leads by 0.86 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Bmw 750Ld xDrive is doing 145 km/h against 135 km/h for the Bmw 840i Gran Coupe. The gap is 0.59 s. The challenger starts to claw back ground.

At 400 metres standing start, the Bmw 750Ld xDrive crosses the line in 12.84 s versus 13.72 s. The 0.88 s gap represents roughly 41 m of track — a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Bmw 750Ld xDrive continues to build its lead. At 600 metres, it runs at 203 km/h versus 189 km/h. At 1,000 metres, the Bmw 750Ld xDrive finishes in 23.18 s versus 24.81 s, with a 1.63 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph — industry threshold) vs 250 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the Bmw 750Ld xDrive and the Bmw 840i Gran Coupe are governed to 250 (i.e. 155 mph — industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold — an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.95 kg/hp vs 5.45 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.39 seconds. The 0.86 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
