Off the line, the Model X Long Range hits 100 km/h in 4.11 s versus 4.34 s for the GLC 400 4MATIC with EQ Technology. Despite the faster sprint time, the GLC 400 4MATIC with EQ Technology is 1 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Model X Long Range is doing 160 km/h against 145 km/h for the GLC 400 4MATIC with EQ Technology. The gap is 0.29 s. The gap remains stable from the start.
At 400 metres standing start, the Model X Long Range crosses the line in 11.92 s versus 12.66 s. The 0.73 s gap represents roughly 36 m of track — a gap visible to the naked eye.
Past 400 metres, the Model X Long Range continues to build its lead. At 600 metres, it runs at 224 km/h versus 201 km/h. At 1,000 metres, the Model X Long Range finishes in 21.31 s versus 23.35 s, with a 2.04 s lead.
Both rivals are electronically governed, but not at the same level: the Model X Long Range is capped at 249 (i.e. 155 mph — industry threshold) km/h, the GLC 400 4MATIC with EQ Technology 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 (3.51 kg/hp vs 5.18 kg/hp) and transmission (Automatic vs auto).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.65 seconds. The 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
