First up could be a Targa version of the Cayman that could stand to bridge the gap between the existing Cayman coupe and its open-top counterpart, the Boxster, with removable (or sliding) roof panels. But that's hardly the extent of it.
In speaking with Automotive News, Mueller hinted at plans to introduce a sub-Boxster four-cylinder sports car based on the Boxster's platform but with the possible use of Volkswagen Golf components to keep costs down.
Beyond that, Porsche has big plans for the Panamera, including possible derivatives (like a coupe or convertible as rumored) as well as spin-offs for other Volkswagen divisions including Audi, Bentley and Lamborghini. One thing's for sure, Porsche's not about to sit back and rely on just one continuing product line any longer.
