Off the line, the GLC 400 4MATIC with EQ Technology hits 100 km/h in 4.34 s versus 6.86 s for the iX3. At this point, the GLC 400 4MATIC with EQ Technology leads by 2.53 s and sits roughly 24 m ahead.
At 200 metres, the GLC 400 4MATIC with EQ Technology is doing 145 km/h against 126 km/h for the iX3. The gap is 1.75 s. The challenger starts to claw back ground.
At 400 metres standing start, the GLC 400 4MATIC with EQ Technology crosses the line in 12.66 s versus 15.07 s. The 2.42 s gap represents roughly 100 m of track - a gap visible to the naked eye.
Past 400 metres, the GLC 400 4MATIC with EQ Technology continues to build its lead. At 600 metres, it runs at 201 km/h versus 172 km/h. At 1,000 metres, the GLC 400 4MATIC with EQ Technology finishes in 23.35 s versus 27.54 s, with a 4.19 s lead.
Both rivals are electronically governed, but not at the same level: the GLC 400 4MATIC with EQ Technology is capped at 210 km/h, the iX3 at 180 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 (5.18 kg/hp vs 7.64 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.53 seconds. The 2.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, GLC 400 4MATIC with EQ Technology X254 wins (4,33 s vs 6,86 s).
GLC 400 4MATIC with EQ Technology X254 goes from 0 to 100 km/h in 4,33 seconds (calibrated simulation).
