Standing and rolling acceleration runs, simulated from published kerb mass, rated power and drivetrain data — then fitted to each car’s full published acceleration profile.
Air density scales aero drag and engine power; surface sets the grip ceiling.
My Auto Racer is a drag race simulator for real cars. Pick any two of 15,000 models, set the distance, the surface and the weather, and watch them run — a full standing start with a Christmas tree, 60 ft, 1/8 mile, 1/4 mile, trap speed and a rolling speed trace for each car.
Every time is simulated, not measured. Each car is modelled from its published kerb mass, rated power, drivetrain and gearing; the model then trims tyre grip and delivered power until the car reproduces its own published acceleration figures. Both cars run in identical conditions — dry asphalt, 20 °C, sea level, 1 ft rollout — which is what makes the comparison fair even though no single time is a timing slip.
