It's been rumored for some time that Audi and Porsche would be teaming up to produce a handful of new models over the next five years. From a manufacturing standpoint, both automakers could benefit from shared development and production costs, while consumers would get their hands on some very compelling product.

The cornerstone of Audi's confusing salvo to "put old luxury on notice" is the expansion of its lineup to fill every conceivable niche. The extension of the "R" line of products – beginning with the R8 – is rumored to include a convertible version of Audi's midship V8 super coupe, along with an R4, R6 and an R10.

Details on the R6, which could slot in between Porsche's Cayman/Boxster and 911 range, and the R10 are scarce, but the next generation Boxster will share a platform with Audi, allowing the four-ringed crew to offer a midship coupe of its own. The R4 is expected to sport the TT's 2.0-liter TFSI four producing 268 hp or a 2.5-liter five-cylinder making upwards of 300 hp. Porsche and Audi are also likely to share everything from aluminum space frames to high-output diesels, torque-vectoring AWD systems and dual-clutch transmissions.

The only concern is how this massive amount of cross-pollination between brands could affect the sales of both automakers. Choice is good, but only if the market can sustain the amount of product being offered.
