Off the line, the Bmw 840i xDrive hits 100 km/h in 4.81 s versus 5.58 s for the Bmw 740Le iPerformance. Despite lacking instant torque, 333 hp of power compensates. At this point, the Bmw 840i xDrive leads by 0.77 s and sits roughly 3 m ahead.
At 200 metres, the Bmw 840i xDrive is doing 142 km/h against 132 km/h for the Bmw 740Le iPerformance. The gap is 0.41 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840i xDrive crosses the line in 13.05 s versus 13.77 s. The 0.72 s gap represents roughly 33 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 840i xDrive continues to build its lead. At 600 metres, it runs at 198 km/h versus 186 km/h. At 1,000 metres, the Bmw 840i xDrive finishes in 23.65 s versus 25.05 s, with a 1.40 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 Bmw 840i xDrive and the Bmw 740Le 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 8.68 seconds. The 0.77 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 840i xDrive G15 wins (4,81 s vs 5,58 s).
840i xDrive G15 goes from 0 to 100 km/h in 4,81 seconds (calibrated simulation).
