Off the line, the S5 Sedan hits 100 km/h in 4.50 s versus 6.03 s for the C 300. At this point, the S5 Sedan leads by 1.53 s and sits roughly 19 m ahead.
At 200 metres, the S5 Sedan is doing 142 km/h against 132 km/h for the C 300. The gap is 1.11 s. The challenger starts to claw back ground.
At 400 metres standing start, the S5 Sedan crosses the line in 12.80 s versus 14.22 s. The 1.42 s gap represents roughly 64 m of track - a gap visible to the naked eye.
Past 400 metres, the S5 Sedan continues to build its lead. At 600 metres, it runs at 198 km/h versus 186 km/h. At 1,000 metres, the S5 Sedan finishes in 23.38 s versus 25.46 s, with a 2.08 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
The S5 Sedan features all-wheel drive (AWD) against the C 300’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 share the same electronic speed cap: the S5 Sedan and the C 300 are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.31 kg/hp vs 6.36 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.14 seconds. The 1.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S5 Sedan wins (4,50 s vs 6,03 s).
S5 Sedan goes from 0 to 100 km/h in 4,50 seconds (calibrated simulation).
