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
1/8 scale rally car on 2.2in tarmac tires.
- Pinion is 1-module, not 48P.
- Internal is the 40T/13T diff bevel pair shared with the RS4 Sport 3 and Bullet.
