Off the line, the P7 hits 100 km/h in 4.22 s versus 4.34 s for the GLC 400 4MATIC with EQ Technology. At this point, the P7 leads by 0.12 s and sits roughly 2 m ahead.
At 200 metres, the P7 is doing 147 km/h against 145 km/h for the GLC 400 4MATIC with EQ Technology. The gap is 0.10 s. The gap remains stable from the start.
At 400 metres standing start, the P7 crosses the line in 12.54 s versus 12.66 s. The 0.11 s gap represents roughly 6 m of track - barely a car length.
Past 400 metres, the situation changes. The P7 maxes out at 170 km/h while the GLC 400 4MATIC with EQ Technology keeps accelerating towards 210 km/h. At 600 metres, the gap has dropped to 0.33 s.
Around 475 metres, both vehicles are level. This is the inversion point: the GLC 400 4MATIC with EQ Technology overcomes its launch deficit thanks to a 40 km/h higher top speed.
At 1,000 metres, the GLC 400 4MATIC with EQ Technology finishes in 23.35 s versus 25.24 s. The 1.90 s delta in favour of the GLC 400 4MATIC with EQ Technology shows that top speed makes a clear difference.
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 P7 at 170 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 4.81 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.65 seconds. The 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, P7 wins (4,21 s vs 4,33 s).
GLC 400 4MATIC with EQ Technology X254 goes from 0 to 100 km/h in 4,33 seconds (calibrated simulation).
GLC 400 4MATIC with EQ Technology X254: 489 hp, ratio 5,18 kg/hp. P7: 424 hp, ratio 4,81 kg/hp.
GLC 400 4MATIC with EQ Technology X254: 210 km/h. P7: 170 km/h.
