Stock is as the vehicle ships. Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart. The top speed is kinematic: an ideal no-load RPM with no slip and no loss under load, so a real car is slower.
How these numbers were settled
Tire diameter is from the original catalog and is not manufacturer-sourced.
