Off the line, the Bmw X3 M40d hits 100 km/h in 4.87 s versus 5.30 s for the Bmw i5 xDrive40. Despite lacking instant torque, 326 hp of power compensates. At this point, the Bmw X3 M40d leads by 0.43 s and sits roughly 8 m ahead.
At 200 metres, the Bmw X3 M40d is doing 138 km/h against 137 km/h for the Bmw i5 xDrive40. The gap is 0.34 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw X3 M40d crosses the line in 13.21 s versus 13.59 s. The 0.38 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the Bmw X3 M40d continues to build its lead. At 600 metres, it runs at 191 km/h versus 191 km/h. At 1,000 metres, the Bmw X3 M40d finishes in 24.24 s versus 24.58 s, with a 0.33 s lead.
The Bmw X3 M40d features all-wheel drive (AWD) against the Bmw i5 xDrive40’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 i5 xDrive40 is capped at 215 km/h, the Bmw X3 M40d at 250 (i.e. 155 mph - industry threshold) 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 8.09 seconds. The 0.43 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X3 M40d G01 wins (4,87 s vs 5,30 s).
