Rumor has it that Porsche is prepping a 911 to serve as an homage to that very machine, and it could arrive in 2015. The German automaker is said to be looking to produce a Speedster version of the current 991-series 911. This means it will be a true open-top motoring machine, with the possibility of an emergency-only roof covering. The rumor states that Porsche will build just 550 examples for the 2015 model year. This means Porsche may unveil the car by as early as January 2014.
