Off the line, the GLC 400 4MATIC hits 100 km/h in 4.34 s versus 4.37 s for the SQ6 SUV e-tron. The 0.03 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the GLC 400 4MATIC is doing 145 km/h against 144 km/h for the SQ6 SUV e-tron. The gap is 0.02 s. The gap remains stable from the start.
At 400 metres standing start, the GLC 400 4MATIC crosses the line in 12.66 s versus 12.70 s. The 0.04 s gap represents roughly 2 m of track
Past 400 metres, the situation changes. The GLC 400 4MATIC maxes out at 210 km/h while the SQ6 SUV e-tron keeps accelerating towards 230 km/h. At 600 metres, the gap has dropped to 0.07 s.
Around 944 metres, both vehicles are level. This is the inversion point: the SQ6 SUV e-tron overcomes its launch deficit thanks to a 20 km/h higher top speed.
At 1,000 metres, the SQ6 SUV e-tron finishes in 23.29 s versus 23.35 s. The 0.06 s delta shows an extremely tight race.
On paper, the SQ6 SUV e-tron combines 509 hp, 855 Nm and 2,425 kg - a clear theoretical edge over the GLC 400 4MATIC. Yet the GLC 400 4MATIC launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the GLC 400 4MATIC has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs - exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.
Both rivals are electronically governed, but not at the same level: the SQ6 SUV e-tron is capped at 230 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 (4.76 kg/hp vs 5.18 kg/hp) and transmission (Unknown vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.73 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
