Porsche has been spotted testing the next-generation 2013 Porsche 911 Turbo out on public streets once again. This is the first time we've been able to see most of the new Turbo's major exterior details.
Details exposed include the front bumper layout, which looks like it will incorporate new larger front air dams in the middle and those increasingly popular side air intakes for the front brakes. The front end will also showcase new spotlights embedded into the very edges of the front bumper bar.
The rear end design will also see some pretty dramatic revisions, including a new rear bumper bar. The shape of the bumper seems more curvaceous than the existing model's and it incorporates the exhaust outlets higher up within the bumper bar mould - unlike the existing model exhaust which exits lower down in the bumper bar.
There also appears to be a new, larger rear spoiler. The spoiler will be hydraulically operable like the current model, and help produce more downforce and airflow over the car.
Engine details for the new 911 Turbo are yet to be finalised, but it is likely to feature a turbocharged flat-six engine of some capacity. Reports suggest it will produce around 420kW, or about the same as the Ferrari 458 Italia and near the Chevrolet Corvette ZR1.
Like the new standard 991 Porsche 911, the 2013 Porsche 911 Turbo will be larger in dimensions than the existing model. It will feature a longer wheelbase and offer more interior room. Reports also say the new model will use plenty of exotic lightweight materials in its construction to keep the weight down even though the size has grown.
The 2013 Porsche 911 is expected to be unveiled sometime after the standard 2012 911 is unveiled at this year's Frankfurt Motor Show in September.
