Off the line, the C 300 hits 100 km/h in 6.03 s versus 7.79 s for the A5 Sedan. At this point, the C 300 leads by 1.76 s and sits roughly 11 m ahead.
At 200 metres, the C 300 is doing 132 km/h against 117 km/h for the A5 Sedan. The gap is 0.87 s. The challenger starts to claw back ground.
At 400 metres standing start, the C 300 crosses the line in 14.22 s versus 15.74 s. The 1.52 s gap represents roughly 60 m of track - a gap visible to the naked eye.
Past 400 metres, the C 300 continues to build its lead. At 600 metres, it runs at 186 km/h versus 162 km/h. At 1,000 metres, the C 300 finishes in 25.46 s versus 28.62 s, with a 3.16 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 242 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the C 300 is capped at 250 (i.e. 155 mph - industry threshold) km/h, the A5 Sedan at 242 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 combustion powertrains, the difference comes down to power-to-weight ratio (6.36 kg/hp vs 8.92 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.41 seconds. The 1.76 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
