Summer signing Ryan Nelsen was given his debut for QPR’s second pre-season friendly in Germany, where Alejandro Faurlin is among the substitutes.
Augsburg went ahead courtesy of a penalty by Aristide Bance, who scored from the spot after a free-kick appeared to strike Kieron Dyer’s hand.
The free-kick was awarded after keeper Robert Green’s misjudgement led to him handling the ball outside of his area.
Rangers levelled with a fine strike from Djibril Cisse, but Anton Ferdinand’s own goal meant the home side led at the interval.
New Zealand captain Nelsen, who was recently involved in the Olympics, lined up at centre-back alongside Ferdinand.
Faurlin, out since January with a knee injury, is expected to feature in the second half.
