Porsche 718 Cayman vs Alfa Romeo 4C

Over a standing quarter mile on dry asphalt the Alfa Romeo 4C is the quicker car, covering it in 12.77 s at 106.7 mph against the Porsche 718 Cayman’s 12.81 s — a margin of 0.04 s. To 60 mph the Alfa Romeo 4C takes 4.41 s and the Porsche 718 Cayman 4.18 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 Porsche 718 Cayman or the Alfa Romeo 4C faster?
The Alfa Romeo 4C. Over a standing quarter mile it runs 12.77 s to the Porsche 718 Cayman's 12.81 s, a margin of 0.04 s, and it reaches 60 mph in 4.41 s against 4.18 s. These are theoretical times from a physics simulation, not measured runs.
What is the Porsche 718 Cayman 0-60 time?
The Porsche 718 Cayman reaches 60 mph in 4.18 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.81 s at 108.9 mph.
What is the Alfa Romeo 4C 0-60 time?
The Alfa Romeo 4C reaches 60 mph in 4.41 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.77 s at 106.7 mph.
What trap speed does each car run?
The Porsche 718 Cayman trips the lights at 108.9 mph and the Alfa Romeo 4C at 106.7 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 Porsche 718 Cayman and 9 of 10 for the Alfa Romeo 4C. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
