We love how Audi just can't stop themselves with the new models. 18 new ones in the coming years is the official company line. Here's one: Looking like the unholy offspring of an A3, a Dodge Magnum and a Mercedes-Benz CLS, somehow this rendering S5 looks pretty good to our wagon loving eyes. Sure, the A4 Avant and A6 Avants are fine cars. No, to our knowledge their will not be an A5 sedan. Why then an A5 station wagon Sportback? Meine Brüder, why the hell not? The Sportback should be wider, taller and more slanty than the A4 Avant. Oh, and hopefully they'll figure out the damn battery for a US bound RS5. [Motor Authority]
