Porsche AG will unveil its Carrera GT 'supercar' in March at the Geneva International Motor Show. The project, which includes a range of motorsport developments such as its V10 engine, ceramic-composite braking and clutch systems and underbody aerodynamics package, has occupied Porsche's Competition Department at the expense of new motorsport programmes. Its completion releases the engineers in Weissach, Germany, for a new motorsport project, soon to be announced.
