The 2013 Porsche 911 Turbo Cabriolet in these latest spy shots shows off a roll bar in the back seats and typically shows us what the new turbocharged Cabriolet model is going to look like.

Initial reports about the version is a 3.8 liter flat six with a pair of diesel style variable turbine geometry turbochargers, but now we hear its a tri-turbocharged variant of the 3.8 liter. Power should be up about 20 horses on both standard and "S" models.

The soft-top model will be offered with a seven-speed manual gearbox or an optional PDK dual-clutch transmission with the same number of gears, and standard all-wheel drive.
