We construct new families of solutions of the heterotic G 2 system on squashed homogeneous 3-Sasakian manifolds, that is, using squashed metrics on either the 7-sphere or the Aloff-Wallach space N 1,1 . We obtain AdS 3 solutions for all values of the squashing parameter s except for the nearly-parallel G 2 value s =1/ √ 5 , for which we don't find any solutions. Along the process, we construct different G 2 -instanton connections on bundles over these squashed manifolds.
