About the Spider 1600 Duetto

The 1966 Alfa Romeo Spider 1600 Duetto is a rear-drive naturally aspirated roadster of 990 kg with 107 bhp, which works out at 108 bhp per tonne. Rear drive and 108 bhp per tonne make the launch the hard part of the run: 60 ft takes 3.09 s. Against the 2,939 cars in the set it is the 2,910th quickest to 60 mph, and the 42nd quickest of the 43 Alfa Romeos here. Its 77.7 mph trap speed sits about where its 0-60 puts it, so it launches and pulls in roughly equal measure. The simulation is trimmed to 9 of 9 published acceleration figures for this car.

Are these real measured times?
No. Every figure on this page is produced by a physics simulation, not by a stopwatch at a drag strip. The Alfa Romeo Spider 1600 Duetto is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 9 of its 9 published acceleration figures. Conditions are the same for every car in the set: dry asphalt, 20 °C, sea level, 1 ft rollout.
