Reports out of France and Germany indicate that in addition to the all-new A8 and A5 Sportback, Audi plans to reveal two versions of the R8 at the Frankfurt Motor Show this September.

Both Auto Motor und Sport and L'Automobile report that Audi will finally reveal the R8 Spyder at the IAA expo, with the French pub saying the drop-top supercar will be available with either the standard 420 hp, 4.2-liter V8 or the newly released 525 hp, 5.2-liter V10, allowing Audi to compete directly with the 911 4S, Turbo and convertible models.

However, the big news is the rumored reveal of an electric version of the R8. Details are scarce, so it's unclear if the R8 concept will be a pure EV, a diesel/gasoline-electric hybrid, a limited production model or, more likely, just an indication that Audi is looking at future powertrains. Regardless, we'll be on the floor in Frankfurt to bring you both the reveals if/when they happen.
