Off the line, the M135i xDrive hits 100 km/h in 4.78 s versus 6.80 s for the 225xe iPerformance. Despite lacking instant torque, 306 hp of power compensates. At this point, the M135i xDrive leads by 2.02 s and sits roughly 19 m ahead.
At 200 metres, the M135i xDrive is doing 144 km/h against 126 km/h for the 225xe iPerformance. The gap is 1.36 s. The challenger starts to claw back ground.
At 400 metres standing start, the M135i xDrive crosses the line in 13.00 s versus 14.96 s. The 1.96 s gap represents roughly 83 m of track - a gap visible to the naked eye.
Past 400 metres, the M135i xDrive continues to build its lead. At 600 metres, it runs at 199 km/h versus 176 km/h. At 1,000 metres, the M135i xDrive finishes in 23.59 s versus 26.93 s, with a 3.34 s lead.
Both rivals are electronically governed, but not at the same level: the M135i xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 225xe iPerformance at 202 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 10.41 seconds. The 2.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M135i xDrive F40 wins (4,78 s vs 6,80 s).
M135i xDrive F40 goes from 0 to 100 km/h in 4,78 seconds (calibrated simulation).
