Our trusty spy photographers have caught the upcoming Porsche 911 Turbo Cabriolet with its top down and its tail up on a stroll through German streets. To our eyes, the extended length and wheelbase are accentuated in the rear-end packaging, but it's still a looker.

Some reports say that motivation will come from a twin-turbo 3.8-liter flat-six, others say there will be three turbos affixed for immediate low-end action. Horsepower ratings are also a muddle for now, with various reports suggesting 515 horsepower or thereabouts, making for a 15-hp increase over the current Turbo, and that would be followed by a Turbo S with somewhere around 550 hp, a 20-hp bump on the present Turbo S. Other reports say the regular turbo will go straight for the 550-hp jugular, leaving the S to haunt the neighborhood of 600 hp.

What we do know is that it will pack all-wheel drive, a seven-speed transmission in traditional stick or PDK, and every electro-bauble in Porsche's arsenal when it finally is revealed. For now, catch what you can in the high-res gallery of spy photos.
