Safe as well as comfortable The occupants of the Turbo Coupe are well protected in the case of an accident by the car's supremely strong structure. In addition, the passenger cabin boasts three-point, inertial-reel safety belts on all seats, with belt-latch tensioners and belt-force limiters in front. The belts are supplemented by six airbags. There are two full-size, two stage front-impact airbags, thorax-protecting side-impact airbags in the front seats and head-protecting side-impact airbags mounted in the doors, as part of the Porsche Side Impact Protection (POSIP) system. In a collision from the side, the POSIP's head airbag inflates upward from its location at door window sill forming a flat cushion with a total capacity of nearly 500 cubic inches (8 liters), helping prevent the occupant’s head from impacting the side window. The passenger-side front airbag relies on a sensor in the front passenger seat that defeats that airbag if the sensor detects a child or very small adult is sitting there. The aluminum doors of the Turbo offer all the occupant protection as the steel ones on other 911 models. In the event of a front impact, extrusion-pressed profiles beneath the doorsill transfer the crash forces to the rear, around the passenger cell. Maximum safety through accident avoidance The Porsche philosophy is firm in the belief that avoiding an accident is always preferable to trying to survive one. All Porsche vehicles benefit from uncanny agility and predictable, instant response to driver commands. To ensure that the Turbo Coupe's chassis is more than equal to the task of letting the driver confidently and fully enjoy the awesome drivetrain, Porsche engineers insisted on a fully capable suspension. The design is based on the existing Carrera 4S suspension, but the Turbo has reconfigured and upgraded springs and shocks, with Porsche Active Suspension Management (PASM) as standard. In addition, Porsche engineers gave the Turbo Coupe a wider track than the previous model, which translates to improved handling, particularly at higher speeds. The front track is 0.71-inches (18- mm) wider, while the rear track has been increased by 0.79 inches (20 mm). Mechanically, the front suspension consists of Porsche configured McPherson struts—with gas pressurized, electronically controlled twin-sleeve shocks—longitudinal and lateral arms and antiroll bar. At the rear, each wheel is located by a multilink setup with five control arms, coil springs mounted over electronically controlled, single sleeve gas pressurized shocks, with an antiroll bar.
