Off the line, the 540i xDrive hits 100 km/h in 4.75 s versus 6.81 s for the i3s. Despite lacking instant torque, 340 hp of power compensates. At this point, the 540i xDrive leads by 2.06 s and sits roughly 18 m ahead.
At 200 metres, the 540i xDrive is doing 145 km/h against 124 km/h for the i3s. The gap is 1.37 s. The challenger starts to claw back ground.
At 400 metres standing start, the 540i xDrive crosses the line in 12.90 s versus 15.05 s. The 2.15 s gap represents roughly 88 m of track - a gap visible to the naked eye.
Past 400 metres, the 540i xDrive continues to build its lead. At 600 metres, it runs at 203 km/h versus 160 km/h. At 1,000 metres, the 540i xDrive finishes in 23.22 s versus 28.59 s, with a 5.37 s lead.
The 540i xDrive features all-wheel drive (AWD) against the i3s’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 540i xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the i3s at 160 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 10.76 seconds. The 2.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 540i xDrive G30 wins (4,75 s vs 6,81 s).
