Off the line, the Model X 90D hits 100 km/h in 5.03 s versus 7.74 s for the 420i xDrive. The instant torque of 967 Nm from the electric motor makes the difference. At this point, the Model X 90D leads by 2.71 s and sits roughly 7 m ahead.
At 200 metres, the Model X 90D is doing 147 km/h against 115 km/h for the 420i xDrive. The gap is 1.33 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model X 90D crosses the line in 13.07 s versus 15.61 s. The 2.54 s gap represents roughly 96 m of track - a gap visible to the naked eye.
Past 400 metres, the Model X 90D continues to build its lead. At 600 metres, it runs at 205 km/h versus 160 km/h. At 1,000 metres, the Model X 90D finishes in 23.32 s versus 28.71 s, with a 5.40 s lead.
Both rivals are electronically governed, but not at the same level: the Model X 90D is capped at 249 (i.e. 155 mph - industry threshold) km/h, the 420i xDrive at 238 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 12.85 seconds. The 2.71 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Model X 90D wins (5,03 s vs 7,74 s).
Model X 90D goes from 0 to 100 km/h in 5,03 seconds (calibrated simulation).
