Off the line, the 840d xDrive hits 100 km/h in 4.73 s versus 5.32 s for the 740Le xDrive iPerformance. Despite lacking instant torque, 340 hp of power compensates. The 0.59 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 840d xDrive is doing 142 km/h against 134 km/h for the 740Le xDrive iPerformance. The gap is 0.28 s. The challenger starts to claw back ground.
At 400 metres standing start, the 840d xDrive crosses the line in 13.00 s versus 13.54 s. The 0.54 s gap represents roughly 25 m of track - two to three car lengths.
Past 400 metres, the 840d xDrive continues to build its lead. At 600 metres, it runs at 198 km/h versus 188 km/h. At 1,000 metres, the 840d xDrive finishes in 23.58 s versus 24.72 s, with a 1.14 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 840d xDrive and the 740Le xDrive iPerformance 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.
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 8.34 seconds. The 0.59 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 840d xDrive G15 wins (4,73 s vs 5,32 s).
840d xDrive G15 goes from 0 to 100 km/h in 4,73 seconds (calibrated simulation).
