Yes, the Concorde actually flew with afterburners, which are notoriously fuel-inefficient. Modern engines can do Mach 2.2 without afterburners.

This was only for take off and acceleration through the trans-sonic regime. It certainly didn't use them for super-cruise at Mach 2; at this speed the engines were operating at their peak efficiency.
