These patent images are likely to be those of the upcoming Porsche 911 Targa. They were published by French publication, TF1.
As you can see from the images, Porsche is adopting a retro look for the 911 Targa that harks back to the original version from the 1960s through to the 1980s.
It features a removable section above the passenger compartment followed by a thick B-pillar in front of a fixed wraparound rear window.
The new Targo is rumoured to be launched in 2014 with two engine choices – a 3.4-litre flat-six developing 257kW and 390Nm, and a more potent 3.6-litre flat-six with 294kW and 440Nm in the 911 Targa S.
