Page 1 of 1 Like its coupe counterpart, the open-air Porsche 911 Carrera 4S, through its wider rear wheel arches flared by 60 millimetres, makes a clear statement, emphasizing that the primary feature in this case is sporting grip on the rear drive wheels. Despite the only slight modification of axle loads and aerodynamic effects remaining only minor, the lowered chassis and suspension of the Carrera 4S are specially designed and tailored for the open body of the car. The result is very sporting and dynamic driving behaviour at all times providing excellent grip and roadholding particularly at high and very high speeds.
The bodyshell of the 911 Carrera 4S Cabriolet is based on its coupe counterpart, the main differences being specific body reinforcements, for example on the side-sills, additional junction plates and reinforcements of the door shaft behind the B-pillar, made for the first time on a Porsche sports car of high-strength DP600 steel and both welded and bonded in the interest of superior stability. All together, these modifications of the bodyshell make this the stiffest body structure on all open-air 911s.
Developing 320 bhp, the 3.6-litre flat-six delivers its power to all four wheels. Featuring four-wheel-drive technology with a viscous multiple-plate clutch, the drivetrain conveys a minimum of 5 per cent to the front wheels and, if necessary, increases this front-wheel power to 40 per cent. Another standard feature is electronic Porsche Stability Management (PSM) which, in combination with four-wheel drive, ensures a particularly high standard of driving safety on the road.
As an option the new 911 Carrera 4S Cabriolet can be fitted with Porsche Ceramic Composite Brakes (PCCB) about 50 per cent lighter than metal brake discs. In conjunction with the brake pads also specially made in this case, the ceramic brake discs immediately develop a very substantial and, in particular, consistent frictional coefficient during application of the brakes.
