The special edition 911 will likely bow at next year's Frankfurt Motor Show.

Porsche has confirmed that it is planning a surprise to commemorate the 50th birthday of the iconic 911.

Speaking at a media event in Austria, August Achleitner, the director of the 911 line, indicated that the automaker will treat its oldest nameplate to "something special" next year. Achleitner declined to give more information but the surprise will likely take the form of a special edition model that will feature a specific treatment inside and out. Whether or not mechanical modifications will be made to the car is not currently known.

Since the Porsche 911 debuted as a thinly-veiled concept dubbed 901 at the 1963 Frankfurt Motor Show, it is a safe bet that the surprise Porsche is preparing will greet the public for the first time at next year's Frankfurt show.

The 50th anniversary model will not be the only addition to the 911 lineup. Achleitner announced that Porsche is planning more versions of the car in order to deal with an ever-changing global market.

"Here in my head there are many more variants [of the 911]," said Achleitner in an interview. "We are not running out of ideas. It will not get boring in the next few years."
