While Porsche->ke1 is trying to delay the official launch of the new generation 911 Turbo, our spy photographers have caught the convertible version testing yet again, this time wearing less camouflage than ever. Compared to the standard 911->ke282 models, the future Turbo->ke571 variant will be distinguished by wider rear fenders, additional cooling vents, a new active rear spoiler, and of course, a soft-top for those nice long drives.

Under the hood, Porsche has placed the same 3.8 liter turbocharged flat six engine tricked to deliver a few more HP compared to the current model. Just like all of the other 911 models previously launched, the future Turbo model will get auto start/stop, thermal management, electrical system recuperation, and the world’s first seven-speed manual transmission (or an optional PDK). Porsche has also been working on improving fuel consumption and CO2 emissions, so expect to see a drop of up to 15%.

The new 911 Turbo, in both coupe and cabrio versions, will be launched sometime during Summer 2012, so stay tuned!
