Right after I made my departure radio call and taxied onto Runway XX (the preferred departure runway) for a short field takeoff. as I released the brakes to start my roll forward I saw an airplane taxiing at high speed past me on the right and then in front of me onto the runway. I immediately re-engaged the brakes and aborted the takeoff. The other aircraft (a Cessna 210) made a radio call saying 'Cessna 210 is back taxing for Runway XY'. We advised him that he had cut in front of us during our takeoff roll. The pilot replied 'I had bad info. I will expedite my taxi out of your way.' The other CFI who was in the left seat of our plane asked for a radio check; and another aircraft in the pattern confirmed that he had heard our radio calls taxiing to the runup area; to the runway; and our departure call. All radio calls I made were loud and clear. There were no calls from the Cessna 210 pilot that cut in front of me until his call that he was back taxing after he had cut in front of my takeoff roll. There is no way he could have not seen me. He had to taxi forward of my position and around me in a very tight area to avoid striking my wingtip or going off of the narrow 40 feet wide runway. Unfortunately the pilot of the 210 was taxiing so fast I could not get his N number; and he never appeared on my ADSB-IN traffic system. He never identified himself as anything other than a Cessna 210.
GA pilot reported taking evasive action after another aircraft passed him on the Runway during takeoff roll.
