Audi A6 2.4 C6 vs Audi S4 B6

Over a standing quarter mile on dry asphalt the Audi S4 B6 is the quicker car, covering it in 13.99 s at 101.3 mph against the Audi A6 2.4 C6’s 16.23 s — a margin of 2.24 s. To 60 mph the Audi S4 B6 takes 5.63 s and the Audi A6 2.4 C6 8.12 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 Audi A6 2.4 C6 or the Audi S4 B6 faster?
The Audi S4 B6. Over a standing quarter mile it runs 13.99 s to the Audi A6 2.4 C6's 16.23 s, a margin of 2.24 s, and it reaches 60 mph in 5.63 s against 8.12 s. These are theoretical times from a physics simulation, not measured runs.
What is the Audi A6 2.4 C6 0-60 time?
The Audi A6 2.4 C6 reaches 60 mph in 8.12 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 16.23 s at 88.0 mph.
What is the Audi S4 B6 0-60 time?
The Audi S4 B6 reaches 60 mph in 5.63 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 13.99 s at 101.3 mph.
What trap speed does each car run?
The Audi A6 2.4 C6 trips the lights at 88.0 mph and the Audi S4 B6 at 101.3 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 Audi A6 2.4 C6 and 10 of 10 for the Audi S4 B6. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
