Audi R8 LMX vs Porsche Cayman GT4 981

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 Porsche Cayman GT4 981’s 12.21 s — a margin of 0.98 s. To 60 mph the Audi R8 LMX takes 3.11 s and the Porsche Cayman GT4 981 3.91 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 Porsche Cayman GT4 981 faster?
The Audi R8 LMX. Over a standing quarter mile it runs 11.23 s to the Porsche Cayman GT4 981's 12.21 s, a margin of 0.98 s, and it reaches 60 mph in 3.11 s against 3.91 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 Porsche Cayman GT4 981 0-60 time?
The Porsche Cayman GT4 981 reaches 60 mph in 3.91 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.21 s at 116.9 mph.
What trap speed does each car run?
The Audi R8 LMX trips the lights at 127.5 mph and the Porsche Cayman GT4 981 at 116.9 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 Porsche Cayman GT4 981. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
