Here we have the latest pictures of the new Porsche 911 (991) Turbo and Turbo Cabrio testing near the Arctic Circle in Sweden. You can see the extra spoiler at the rear, side intake ports, wider rear, rear bumper with additional cooling vents and also quad-exhaust tips, though one of the 911 Turbo Cabrio prototypes still has the single exhausts, like the early stage prototypes.
The new Porsche 911 Turbo is rumoured to have three-turbos and around 550bhp. An updated PDK dual-clutch gearbox is also expected, while the seven-speed manual should be available as well.
The new 911 Turbo is expected to debut at the Frankfurt Auto Show in September.
