Off the line, the 750Ld xDrive hits 100 km/h in 4.63 s versus 5.36 s for the 840i Convertible. At this point, the 750Ld xDrive leads by 0.73 s and sits roughly 7 m ahead.
At 200 metres, the 750Ld xDrive is doing 145 km/h against 137 km/h for the 840i Convertible. The gap is 0.50 s. The challenger starts to claw back ground.
At 400 metres standing start, the 750Ld xDrive crosses the line in 12.84 s versus 13.59 s. The 0.75 s gap represents roughly 35 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 191 km/h. At 1,000 metres, the 750Ld xDrive finishes in 23.18 s versus 24.56 s, with a 1.38 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.
Both rivals share the same electronic speed cap: the 750Ld xDrive and the 840i Convertible 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 5.38 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.17 seconds. The 0.73 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 750Ld xDrive G11 wins (4,63 s vs 5,36 s).
750Ld xDrive G11 goes from 0 to 100 km/h in 4,63 seconds (calibrated simulation).
