Off the line, the Model X Performance hits 100 km/h in 3.05 s versus 4.34 s for the GLC 400 4MATIC. At this point, the Model X Performance leads by 1.29 s and sits roughly 10 m ahead.
At 200 metres, the Model X Performance is doing 168 km/h against 145 km/h for the GLC 400 4MATIC. The gap is 1.12 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 12.66 s. The 1.74 s gap represents roughly 83 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 201 km/h. At 1,000 metres, the Model X Performance finishes in 19.92 s versus 23.35 s, with a 3.43 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 400 4MATIC at 210 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.
With two electric powertrains, the difference comes down to power-to-weight ratio (3.16 kg/hp vs 5.18 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.65 seconds. The 1.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
