Volkswagen's plans to roll out three production versions of the BlueSport Concept sparked all sorts of discussions on which vehicles would get treated to the design. As of now it looks as if Porsche will be dishing out the 550 (Baby Boxster?) based on the iconic 550 Spyder launched in 1953, Volkswagen will be serving up the Bluesport production model using the concept's design, and Audi will be treating us to the R4.

The new Audi R4 will only be offered in a roadster version and will take its design inspiration from the E-tron Spyder concept, as well as new design lines that will also be seen in the next generation R8 supercar. It will be powered by a choice of three engines, including the current 2.0-liter four-cylinder turbocharged engine featuring a new variable cam and valve lift control system and an output of about 280 HP. The second choice will be a turbocharged 2.5-liter five-cylinder engine with an output of about 350 HP and the third will be a twin-turbocharged 2.0-liter four-cylinder diesel with an output of about 200bhp and 295lb ft.

Audi will be debuting the new R4 sometime in 2014 with sales starting in 2015 at about $40,000-$45,000.
