I was pretty disappointed about this. The predecessor games to Elite Dangerous, Frontier and Frontier First Encounters, had a Newtonian flight model (and an optional "time acceleration" feature to artificially shorten intra-system flight time).
Pioneer also exists as an open source Frontier remake, with the same sort of flight model and universe: http://pioneerspacesim.net/
Realistically a space battle would be, does the evader want to evade and has more thrust? => they evade, else, the attacker approaches and both get to shoot until one is dead. There would be no real combat other than weapon size and armour plating. I don't think there would be space dogfights as the onboard computers would just be able to track each other too accurately / apply optimal game theoretic evasions given the constraints. Boring ... might as well play spreadsheets.
See, point, shoot.
