Audi always seems to have something great in store for us at the Detroit Auto Show every year, and in addition to the Sportback Concept, the long-awaited R8 V10 5.2 FSI made its official world debut at this year's show. With the 5.2L V10 plucked from the Gallardo LP560-4 mounted amidships, the new R8 now packs 525 horsepower and 391 lb-ft torque. Exterior styling has been subtly updated and includes all-LED headlights, wide side sills, revised matte aluminum exhaust tips, and new 19-inch 10-spoke wheels
