Several recent all-speed time-explicit numerical methods for the Euler equations on Cartesian grids are presented and their properties assessed experimentally on a complex application. These methods are truly multi-dimensional, i.e. the flux through an interface also depends on the values in cells adjacent to the endpoints of the edges (corners).
