About the CD Coupe Diplomat

The 1973 Bitter CD Coupe Diplomat is a rear-drive naturally aspirated car of 1,720 kg with 228 bhp, which works out at 133 bhp per tonne. Rear drive and 133 bhp per tonne make the launch the hard part of the run: 60 ft takes 3.05 s. Against the 2,929 cars in the set it is the 2,823rd quickest to 60 mph, and the 2nd quickest of the 2 Bitters here. Its 84.2 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 Bitter CD Coupe Diplomat 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.
