Off the line, the GLC 400 4MATIC hits 100 km/h in 4.34 s versus 6.12 s for the i5 eDrive40. At this point, the GLC 400 4MATIC leads by 1.79 s and sits roughly 21 m ahead.
At 200 metres, the GLC 400 4MATIC is doing 145 km/h against 135 km/h for the i5 eDrive40. The gap is 1.31 s. The challenger starts to claw back ground.
At 400 metres standing start, the GLC 400 4MATIC crosses the line in 12.66 s versus 14.29 s. The 1.64 s gap represents roughly 73 m of track - a gap visible to the naked eye.
Past 400 metres, the GLC 400 4MATIC continues to build its lead. At 600 metres, it runs at 201 km/h versus 186 km/h. At 1,000 metres, the GLC 400 4MATIC finishes in 23.35 s versus 25.87 s, with a 2.52 s lead.
The GLC 400 4MATIC features all-wheel drive (AWD) against the i5 eDrive40’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the GLC 400 4MATIC is capped at 210 km/h, the i5 eDrive40 at 193 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 6.81 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.92 seconds. The 1.79 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, GLC 400 4MATIC X254 wins (4,33 s vs 6,12 s).
GLC 400 4MATIC X254 goes from 0 to 100 km/h in 4,33 seconds (calibrated simulation).
