Off the line, the S8 hits 100 km/h in 3.83 s versus 4.34 s for the GLC 400 4MATIC with EQ Technology. Despite lacking instant torque, 571 hp of power compensates. At this point, the S8 leads by 0.50 s and sits roughly 5 m ahead.
At 200 metres, the S8 is doing 157 km/h against 145 km/h for the GLC 400 4MATIC with EQ Technology. The gap is 0.46 s. The gap remains stable from the start.
At 400 metres standing start, the S8 crosses the line in 11.81 s versus 12.66 s. The 0.85 s gap represents roughly 41 m of track - a gap visible to the naked eye.
Past 400 metres, the S8 continues to build its lead. At 600 metres, it runs at 222 km/h versus 201 km/h. At 1,000 metres, the S8 finishes in 21.26 s versus 23.35 s, with a 2.08 s lead.
Both rivals are electronically governed, but not at the same level: the S8 is capped at 250 (i.e. 155 mph - industry threshold) km/h, the GLC 400 4MATIC with EQ Technology 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.65 seconds. The 0.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S8 wins (3,83 s vs 4,33 s).
S8 goes from 0 to 100 km/h in 3,83 seconds (calibrated simulation).
