Off the line, the Model X Performance hits 100 km/h in 3.05 s versus 7.77 s for the GLC 220 d 4MATIC. The instant torque of 1,139 Nm from the electric motor makes the difference. At this point, the Model X Performance leads by 4.72 s and sits roughly 20 m ahead.
At 200 metres, the Model X Performance is doing 168 km/h against 116 km/h for the GLC 220 d 4MATIC. The gap is 3.09 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model X Performance crosses the line in 10.92 s versus 15.67 s. The 4.75 s gap represents roughly 176 m of track - a gap visible to the naked eye.
Past 400 metres, the Model X Performance continues to build its lead. At 600 metres, it runs at 233 km/h versus 163 km/h. At 1,000 metres, the Model X Performance finishes in 19.92 s versus 28.57 s, with a 8.65 s lead.
Both rivals are electronically governed, but not at the same level: the Model X Performance is capped at 262 km/h, the GLC 220 d 4MATIC at 222 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 12.53 seconds. The 4.72 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Model X Performance wins (3,05 s vs 7,77 s).
Model X Performance goes from 0 to 100 km/h in 3,05 seconds (calibrated simulation).
