AbstractFor any m ≥ 3, we construct properly convex open sets Ω in the real projective space
$$\mathbb{P}^m$$ whose Hilbert metric is Gromov hyperbolic but is not quasiisometric to the hyperbolic space
$$\mathbb{H}^m$$. We show that such examples cannot exist for m = 2.Some of our examples are divisible, i.e. there exists a discrete group Г of projective transformations preserving Ω with a compact quotient Г\Ω. The open set Ω is strictly convex but the group Г is not isomorphic to any cocompact lattice in the isometry group of
$$\mathbb{H}^m$$.
