Off the line, the GLC 400 4MATIC with EQ Technology hits 100 km/h in 4.34 s versus 4.84 s for the I-PACE EV400. At this point, the GLC 400 4MATIC with EQ Technology leads by 0.50 s and sits roughly 7 m ahead.
At 200 metres, the GLC 400 4MATIC with EQ Technology is doing 145 km/h against 141 km/h for the I-PACE EV400. The gap is 0.38 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 13.18 s. The 0.53 s gap represents roughly 25 m of track - two to three car lengths.
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 192 km/h. At 1,000 metres, the GLC 400 4MATIC with EQ Technology finishes in 23.35 s versus 24.36 s, with a 1.01 s lead. Both vehicles have similar top speeds (210 vs 200 km/h), preventing any comeback.
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 I-PACE EV400 at 200 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 5.52 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.37 seconds. The 0.50 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.
