Audi R8 LMX vs Audi Q7 4.2 FSI Mk I

Over a standing quarter mile on dry asphalt the Audi R8 LMX is the quicker car, covering it in 11.23 s at 127.5 mph against the Audi Q7 4.2 FSI Mk I’s 15.29 s — a margin of 4.05 s. To 60 mph the Audi R8 LMX takes 3.11 s and the Audi Q7 4.2 FSI Mk I 6.88 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 R8 LMX or the Audi Q7 4.2 FSI Mk I faster?
The Audi R8 LMX. Over a standing quarter mile it runs 11.23 s to the Audi Q7 4.2 FSI Mk I's 15.29 s, a margin of 4.05 s, and it reaches 60 mph in 3.11 s against 6.88 s. These are theoretical times from a physics simulation, not measured runs.
What is the Audi R8 LMX 0-60 time?
The Audi R8 LMX reaches 60 mph in 3.11 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 11.23 s at 127.5 mph.
What is the Audi Q7 4.2 FSI Mk I 0-60 time?
The Audi Q7 4.2 FSI Mk I reaches 60 mph in 6.88 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 15.29 s at 92.9 mph.
What trap speed does each car run?
The Audi R8 LMX trips the lights at 127.5 mph and the Audi Q7 4.2 FSI Mk I at 92.9 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 — 8 of 11 for the Audi R8 LMX and 9 of 10 for the Audi Q7 4.2 FSI Mk I. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
