Mercedes-Benz C63 AMG Coupe vs Audi RS3 Sedan 8Y Facelift

Over a standing quarter mile on dry asphalt the Audi RS3 Sedan 8Y Facelift is the quicker car, covering it in 11.77 s at 117.1 mph against the Mercedes-Benz C63 AMG Coupe’s 12.55 s — a margin of 0.78 s. To 60 mph the Audi RS3 Sedan 8Y Facelift takes 3.35 s and the Mercedes-Benz C63 AMG Coupe 4.17 s.

Simulated, not measured — computed from each car’s published kerb mass, rated power and drivetrain, then fitted to its own published acceleration figures. Dry asphalt, 20 °C, sea level, 1 ft rollout.

Questions

Is the Mercedes-Benz C63 AMG Coupe or the Audi RS3 Sedan 8Y Facelift faster?
The Audi RS3 Sedan 8Y Facelift. Over a standing quarter mile it runs 11.77 s to the Mercedes-Benz C63 AMG Coupe's 12.55 s, a margin of 0.78 s, and it reaches 60 mph in 3.35 s against 4.17 s. These are theoretical times from a physics simulation, not measured runs.
What is the Mercedes-Benz C63 AMG Coupe 0-60 time?
The Mercedes-Benz C63 AMG Coupe reaches 60 mph in 4.17 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.55 s at 114.5 mph.
What is the Audi RS3 Sedan 8Y Facelift 0-60 time?
The Audi RS3 Sedan 8Y Facelift reaches 60 mph in 3.35 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 11.77 s at 117.1 mph.
What trap speed does each car run?
The Mercedes-Benz C63 AMG Coupe trips the lights at 114.5 mph and the Audi RS3 Sedan 8Y Facelift at 117.1 mph at the end of the quarter mile. These are theoretical times from a physics simulation, not measured runs.
Are these real measured times?
No. Every time on this page is produced by a physics simulation, not by a stopwatch at a drag strip. Each car is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it matches its own published acceleration figures — 9 of 10 for the Mercedes-Benz C63 AMG Coupe and 9 of 10 for the Audi RS3 Sedan 8Y Facelift. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
