The two new 911 variants are branded as the Carrera and the high performance Carrera S. These newly developed models will be available in Europe later this year. The manufacturer, which builds only three model lines – the Cayenne SUV, Boxster coupe and 911 – is also thinking of increasing its range by launching a fourth new model. The new addition will probably be a four-door sports car and Porsche would expect it to push its annual sales up from around 75,000 units this year to approximately 100,000.
