Off the line, the Bmw X7 xDrive50i hits 100 km/h in 5.33 s versus 5.58 s for the Bmw 740Le iPerformance. Despite lacking instant torque, 462 hp of power compensates. Despite the faster sprint time, the Bmw 740Le iPerformance is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw X7 xDrive50i is doing 137 km/h against 132 km/h for the Bmw 740Le iPerformance. The gap is 0.07 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X7 xDrive50i crosses the line in 13.57 s versus 13.77 s. The 0.20 s gap represents roughly 9 m of track - barely a car length.
Past 400 metres, the Bmw X7 xDrive50i continues to build its lead. At 600 metres, it runs at 190 km/h versus 186 km/h. At 1,000 metres, the Bmw X7 xDrive50i finishes in 24.64 s versus 25.05 s, with a 0.41 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 X7 xDrive50i 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 0.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X7 xDrive50i G07 wins (5,33 s vs 5,58 s).
