Off the line, the Bmw 840i xDrive hits 100 km/h in 4.81 s versus 6.58 s for the P7. Despite lacking instant torque, 333 hp of power compensates. At this point, the Bmw 840i xDrive leads by 1.77 s and sits roughly 18 m ahead.
At 200 metres, the Bmw 840i xDrive is doing 142 km/h against 127 km/h for the P7. The gap is 1.20 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 14.81 s. The 1.76 s gap represents roughly 74 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 170 km/h. At 1,000 metres, the Bmw 840i xDrive finishes in 23.65 s versus 27.64 s, with a 3.99 s lead.
The Bmw 840i xDrive features all-wheel drive (AWD) against the P7’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the Bmw 840i xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the P7 at 170 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
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 10.18 seconds. The 1.77 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 6,58 s).
