Off the line, the M440i xDrive hits 100 km/h in 4.47 s versus 6.31 s for the P7i. Despite lacking instant torque, 374 hp of power compensates. At this point, the M440i xDrive leads by 1.84 s and sits roughly 18 m ahead.
At 200 metres, the M440i xDrive is doing 146 km/h against 129 km/h for the P7i. The gap is 1.29 s. The challenger starts to claw back ground.
At 400 metres standing start, the M440i xDrive crosses the line in 12.65 s versus 14.56 s. The 1.91 s gap represents roughly 81 m of track - a gap visible to the naked eye.
Past 400 metres, the M440i xDrive continues to build its lead. At 600 metres, it runs at 204 km/h versus 178 km/h. At 1,000 metres, the M440i xDrive finishes in 22.93 s versus 26.38 s, with a 3.44 s lead.
The M440i xDrive features all-wheel drive (AWD) against the P7i’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 M440i xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the P7i at 200 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 9.78 seconds. The 1.84 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M440i xDrive G22 wins (4,47 s vs 6,31 s).
M440i xDrive G22 goes from 0 to 100 km/h in 4,47 seconds (calibrated simulation).
