Audi A6 2.4 C6 vs Audi A8 4.2 quattro

Over a standing quarter mile on dry asphalt the Audi A8 4.2 quattro is the quicker car, covering it in 14.61 s at 99.9 mph against the Audi A6 2.4 C6’s 16.23 s — a margin of 1.62 s. To 60 mph the Audi A8 4.2 quattro takes 6.36 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 A8 4.2 quattro faster?
The Audi A8 4.2 quattro. Over a standing quarter mile it runs 14.61 s to the Audi A6 2.4 C6's 16.23 s, a margin of 1.62 s, and it reaches 60 mph in 6.36 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 A8 4.2 quattro 0-60 time?
The Audi A8 4.2 quattro reaches 60 mph in 6.36 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 14.61 s at 99.9 mph.
What trap speed does each car run?
The Audi A6 2.4 C6 trips the lights at 88.0 mph and the Audi A8 4.2 quattro at 99.9 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 9 of 10 for the Audi A8 4.2 quattro. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
