Porsche is taking its time to iron out all the kinks on the upcoming 911 Turbo models of its brand-new 991 series, the Carrera and Carrera S versions of which have already been announced.

This time, our crafty spy photographers caught up with the new 911 Turbo Cabriolet during cold weather tests near the Arctic Circle. Like the Carrera/S models, the Turbo Cabriolet features a retractable soft top made out of composite materials supported by a new magnesium frame to keep the weight down.

However, the Turbo variant also sports a wider bodywork in the rear along with a prominent rear wing, redesigned front and rear bumpers, 20-inch wheels and eye-catching air inlets on its hips.

The big surprise for the 991 Turbo may very well come from the engine bay as according to recent reports from British media, the new model may get a tri-turbocharged variant of Porsche’s 3.8-liter flat-six.

The setup is said to comprise a smaller turbocharger positioned closer to the 3.8-liter flat-six for instant response and increased torque at low revs, and two larger units that are similar to the Variable Turbine Geometry turbochargers employed by the current 997 Turbo.

The system will help the engine provide a more linear delivery of power and at the same time, improve fuel economy and reduce CO2 emissions.
