The Gauss-Seidel B50 is a classic car from the game Teardown. It is very well known because of its relevance in the Teardown campaign, when Lawrence Lee Jr. wins two classic cars from a classic car auction in Black River at Löckelle Municipality, which are the Jacobi SL and the Gauss-Seidel B50. Then, Gordon Woo, a wealthy contractor, asks the player to steal the cars at the West Point Marina from Lee, which angers him, starting the conflict.
