If there was ever a prize for the most spied car this year, it should go to the new Porsche 991, which we will come to know as the latest generation of the 911. Our spy shooters have caught up with a variety of prototypes ranging from the standard Carrera coupe all the way up to the Turbo Convertible.

This time they snagged what looks to be either the Carrera or the Carrera S, possibly in final production trim as the car was fitted with the white protective strips we normally find on vehicles that are to be transported. There's also a tag on the passenger seat, but we couldn't zoom close enough to make out what it says.

Truth to be said, we've spied the upcoming Porsche 991 -that's Porsche talk for the next generation of the 911- more times than we can remember these past few months. In fact, just earlier today we brought you some fresh spy shots of the 2013 Porsche 911 Turbo Convertible.

So what's new about these latest scoop pictures? Well, we get a clearer look at both the regular coupe and convertible models of the 911 series without any of that annoying body camouflage.

However, Porsche's engineers have retained the fake surrounds on the headlamps and taillights to confuse us (insert tongue-in-cheek comment here) on the appearance of the 991.

Our spy photographers continue to capture test mules of the upcoming, next generation Porsche 911, which is internally referred to as the 991, ahead of the sports car world premiere at the 2011 Frankfurt Motor Show in September.

We have already shown you the regular 911 Carrera models in both coupe and convertible format as well as the 911 Turbo and what we believe is the 911 Turbo S coupe, but now we have some fresh spy shots of the 911 Turbo Convertible with its top down, caught during hot weather testing.

One could try to explain why such a hotly anticipated new model like the 2012 Porsche 911 was caught out in the open alone (?) and almost completely undisguised, but why bother; it is what it is and you can enjoy the clip and get your first unobstructed view of the 991 in the video after the break.

We’ll just remind you that the next generation of the 911 is due to be unveiled in a world premiere at the 2011 Frankfurt Motor Show in mid-September.

The most famous Porsche model series of all, will mostly likely be offered in two basic flavors at launch, the Carrera with a 350HP 3.4-liter flat-six and the Carrera S powered by a 3.8-liter boxer delivering around 400 ponies.

Show any Porsche 911 to someone old enough to remember when Memorial Day was called Decoration Day, and chances are he or she will probably know the brand and model of the car. But ask someone to tell your which version they’re looking at and you’ll have a pretty hard time getting the right answer unless they’re a true Porschephile.

Take this 911 for example; even our experienced scoop photographers aren’t 100 percent sure about this 2012 Porsche 991 prototype that they bagged testing in Europe.

The chunky rear section with the blistered wheel arches and air-intakes along with the double wing at the back featuring a fixed lower part and a retractable upper section, leave few doubts that this is the new 911 Turbo.

The wait for the next evolution of the Porsche 911 is almost over. In fact, we’re so close to the launch date that the German firm has just entered the teasing phase releasing the first official video of the sports car shot during hot weather testing in South Africa.

The public will have its first chance to see the new 911, codenamed 991, at the 2011 Frankfurt Motor Show in September. What we know up until now is that, the 911 will look like, well, a 911 – don’t forget, it’s all about evolution when it comes to Porsche's most famous model.

The next Porsche 911 will make its world premiere in base trim at the forthcoming Frankfurt motor show this September, but this will only be the first chapter of the 991 saga as the Stuttgart-based firm plans to create an entire range of sub models.

The 911’s lineup will eventually grow to include numerous body styles such as coupe, convertible, Targa and speedster models as well as a variety of standard and limited production versions ranging from the entry level Carreras in two- and four-wheel drive layouts to the GT-spec track racers and the almighty Turbo, which our spies caught testing in Germany.

The new 911, code-named 991, isn’t the only new model that Porsche is working on these days. The second generation Cayman is getting ready for its debut.

We’ve ve already seen the first camouflaged prototypes of the 2013 Cayman, but now it seems that Porsche is gearing up its development program and testing the car in Nurburgring in view of the anticipated 2012 launch, which will coincide with that of its open-top sibling, the Boxster.

Even though the shape is familiar and closely follows the lines of the current model, every panel in the bodywork is, in fact, new. The second-gen Cayman will bigger in all dimensions, including the wheelbase, to provide more ample space for the driver and his or her passenger.

The wall of secrecy surrounding the brand-new 2012 Porsche 911 has cracked thanks to a forum member of Teamspeed who downloaded and shared Car & Driver’s upcoming August issue in which the magazine has an exclusive first ride of the car. C&D joined the Porsche team during the new 911’s final tests in South Africa nd here’s what they found out.

The new 911 is code-named 991 and will be launched in September at the Frankfurt Motor Show. Compared to the 997 that it replaces, it is 2.5 inches longer and has a 4.0-inch longer wheelbase so that it can accommodate a hybrid system, presumably from the Panamera.

We’ve already brought you spy photos of the coupe variant of the 2012 Porsche 911, but now we’ve got our hands on pictures of the open top model caught in action. As you can see, Porsche is sticking with its tried-and-tested cloth top, while the design looks very similar to today’s second-generation 997, albeit with some new details here and there. Read more »
