Road Test Gemballa GT Porsche 991 Cabriolet

Following our first review of the new 911 (991 Series) Coupe and the tuning programs from TechArt and SpeedArt, it was time to have a look at the brand new 2012 Porsche 991 Cabriolet, which is the sum of 30 years of 911 convertibles. In the end it has a similar setup as the 991 Coupe, but with the ability to remove the roof electronically. German tuner Gemballa provided a Porsche 991 Carrera S convertible fitted with their latest kit as our ride for the day. The most noticeable and fundamental difference with our previous experiences inside the new 991 was the new roof. Like previous 911s, Porsche added an intelligent system to the car, which offers a good-looking Coupe-like silhouette when its closed and excellent open-top drive when it is opened. But it is not simply the old top on the new car. The new roof is an evolution with respect to its predecessor. The new panel bow roof design has solid magnesium panels hidden beneath the fabric surface. These create a smooth and rigid finish and an excellent cover when the roof is closed. The design also includes the use of aluminum and high strength steel, which ensures lower vehicle mass. The roof system adds a total of only 36kg to the weight of the car. You can open and close the roof up to a speed of 50km/h and it finishes its roof dance after just 13 seconds.
