Fitted as standard to 911 Turbo models, the 19-inch 911 Turbo II wheels seamlessly combine function and design.

The car has 8.5 J x 19 wheels at the front combined with 235/35 ZR 19 tires. At the rear are 11 J x 19 wheels with 305/30 ZR 19 tires. The wheels are forged, of course, to reduce weight and unsprung masses. The material is also very strong, making it possible to achieve a fine spoke wheel design which provides better ventilation of the brakes.

The five-spoke design is stylish and distinctive. The linear twin spokes have a high-sheen surface

finish, contrasting with the titanium-colored base paint. Part of the wheel rim also has a high-sheen finish.

Reminiscent of the classic RS Spyder design, these forged aluminum wheels with a motorsport-derived central locking device are available on request for the 911 Turbo models and are fitted as standard to the new 911 Turbo S models. By reducing rotating masses, they deliver an even more agile driving experience. Benefiting from innovative ongoing developments to the

engineering conventionally used only in a racing environment, the striking central locking devices offer effective protection against corrosion and are easy to clean.

Alternatively, the 19-inch 911 Turbo II wheels are available for the 911 Turbo S models at no extra cost.

Tire Pressure Monitoring, included as standard equipment, warns against tire pressure loss. The driver is informed via the on-board computer display.

The driver can check the pressures of all four tires from the instrument cluster. Each time the tires are re-inflated, or whenever a wheel has been changed, the updated tire pressures are displayed quickly – for increased comfort and safety.

Included as standard equipment, Porsche Active Suspension Management (PASM) is an electronic active damping system. It offers continuous adjustment of the damping force on each wheel, based on current road conditions and driving style.

At the press of a button, the driver can choose between two modes. While ‘Normal’ mode provides a blend of performance and comfort, the ‘Sport’ setup mode has a much firmer range of settings. The system responds to changing road conditions and/or driving style by continuously varying the individual damping forces within the parameters defined for the selected setup mode (‘Normal’ or ‘Sport’). Pitch and roll are reduced, whilst contact of each wheel with the road is optimized.

The Sport Chrono Package Turbo with dynamic engine mount system is standard on 911 Turbo S models and available as an option for 911 Turbo models. This integrated system provides simultaneous enhancement for engine, chassis and transmission.

Key features include a digital and analog stopwatch on the dashboard, a performance display, a personal memory function in the Porsche Communication Management (PCM), the SPORT button and – in combination with PDK – the SPORT PLUS button, and an additional display on the steering wheel which informs the driver if the SPORT buttons and Launch Control have been activated. The 911 Turbo models additionally offer the ‘overboost’ function. This is how it works:

When ‘Sport’ mode is selected, the engine management system creates a much more aggressive

response to pedal inputs. To do this, it implements an alternative throttle map which relates the pedal position in the footwell to a wider angle of opening in the throttle body. In higher gears, it uses a hard rev-limiter to protect the engine under power.

In the 911 Turbo models, under full acceleration, the maximum boost pressure in the lower and medium speed ranges is now temporarily increased by approximately 2.9 psi. As a result, engine torque is boosted by 480 lb.-ft. to a maximum of 516 lb.-ft. for a limited period. (The 911 Turbo S models are configured to operate with a higher boost pressure level, which means that their maximum torque is always 516 lb.-ft.)

In addition to the engine, ‘Sport’ mode is enabled in the standard Porsche Active Suspension

Management (PASM) suspension. The dampers become firmer, enabling faster turn-in as well as better contact with the road.

In automatic mode of PDK, the basic gearshift pattern is switched to high-performance mode. The gear change action is virtually instantaneous, while the shift points are timed for maximum acceleration. Lift off the throttle – even at high revs – and the system automatically shifts down to apply engine braking. In manual shift mode, gear changing is faster and more dynamic.

Porsche Stability Management (PSM) is also adapted, with the intervention threshold raised. As a result, the car has a more natural response to lateral and longitudinal forces. Cornering agility is greatly enhanced, when both braking to turn in and applying power on exit – particularly in

low-speed curves. For even greater driving pleasure.

For maximum manoeuvrability, PSM can be partially disabled while the car is still in ‘Sport’ mode. PSM simply monitors the forces acting on the car and will only intervene in the most critical scenarios, e.g. when ABS assistance is required on both front wheels.

In conjunction with PDK (standard on 911 Turbo S models), the Sport Chrono Package Turbo with dynamic engine mount system has two additional functions that can be activated via the SPORT PLUS button, for a sporty drive that borders on a motorsport experience.

The first function is ‘Launch Control’, which, for example when performing laps, helps you achieve

optimum acceleration from a standing start, a racing start in other words.

The function works like this: press the SPORT PLUS button when the transmission is in ‘D’ or ‘M’. Then, with your left foot, press the brake pedal and accelerate fully with the right foot. The car recognizes ‘Launch’ mode from the accelerator kickdown action and adjusts the engine speed to the optimum level, which is around 5,000 rpm. At the same time, boost pressure is increased to approximately 7.3 psi, engine torque is increased and the clutch is applied lightly. ‘Launch Control’ now appears in the steering wheel display. Now release the brake as quickly as you can – and feel the acceleration power unleashed to the road.

The second function is the ‘motorsport-derived gearshift strategy’. Using this, Porsche

Doppelkupplung (PDK) is geared up for the shortest possible shift times and optimum shift points for maximum acceleration – ideal for the racetrack.

A key component of the Sport Chrono Package Turbo with dynamic engine mount system is the stopwatch mounted on the dashboard. Porsche Communication Management (PCM) has a special performance display to view, store and evaluate lap times or other driving times. It shows the total driving time, lap distance, lap number and the lap times recorded so far. You can view the current fastest lap and the remaining range until empty. Traveled distances can be recorded and benchmark times defined.

The personal memory function of the Sport Chrono Package Turbo can also be used to store

personalized settings for a range of systems, including the orientation lighting or air conditioning.

Stiffness and softness as required. That’s the principle behind the dynamic engine mount system now being offered for the first time as part of the Sport Chrono Package Turbo. Essentially, it’s an electronically controlled system for controlling the stiffness of the engine mounts.

The engine is bolted to the body using two mounts and follows Newton’s law of inertia, namely that a body will continue to move in a uniform straight line unless it is made to change its direction by a force acting upon it.

Put more simply: when you are driving into a curve, the vehicle will follow your steering but, at first, the mass of the engine won’t. This means that the rear of the vehicle is pushed outwards because of the inert forces from the engine’s mass acting on it.

The dynamic engine mount system minimizes this effect. The steering angle longitudinal and lateral acceleration values are constantly recorded by sensors and the stiffness of the two engine mounts is changed automatically according to the driving style. This is achieved using a magneticable (magnetorheological) fluid and an electrically generated magnetic field. The magneticable particles align with each other and the fluid’s viscosity changes. This alters the stiffness and absorption of the engine mounts: softer for greater comfort and less vibration when driving normally, harder for a more direct driving feel when driving more sportily.

The dynamic engine mount system also reduces the vertical oscillations of the engine when accelerating under full load. The result: greater and more uniform force on the rear axle, increased traction and better acceleration.

All this means two things: perceptibly more stable handling under load change conditions and in fast corners and a step closer to the ultimate sporty drive – combined with enhanced levels of comfort.

The independent front suspension combines McPherson-type struts with longitudinal and transverse links. Each front wheel is precisely located, ensuring excellent handling and directional stability.

Proven in motorsport, the rear axle assembly features multi-link LSA (Lightweight, Stable, Agile) subframe-based suspension. Its lightweight construction offers excellent dynamic properties. The axle kinematics improves stability under acceleration by reducing excessive compression. The lightweight strut has an aluminum damper instead of conventional steel to help improve handling and agility.

The resulting suspension enables smooth high-speed maneuvers in all road and track scenarios.

Pitch and roll are reduced to a minimum, as are tire noise and vibration. The car offers exceptionally high levels of stability.

Sensitive and direct, the power-assisted steering also offers accurate feedback from the road. For a sports car, driver effort is minimal. In short: all the precision of a race-designed system, yet perfect for everyday road use.

One of the key features of the steering system is the variable-ratio gearing. Around the straight-ahead position, the ratio is less direct, enabling smoother maneuvers on the motorway. It also reduces the risk of excessive steering inputs which could destabilize the car at high speed. Agility and feedback, however, are maintained.

Turn the wheel harder and the ratio becomes more direct, enabling better control through low-speed corners as well as easier parking manoeuvres. The turning circle is a modest 35.8 feet.

The Bi-Xenon(TM) headlight system is fitted as standard. The brightness of the lights is approximately twice as great as that of conventional halogen lights. Light output is improved and the road illuminated more uniformly on both low and high beam, helping to minimize driver fatigue. Also included is dynamic range control to prevent hazardous dazzling of oncoming vehicles due to undulations in the road or the loading of the car. A headlight cleaning function is also incorporated.

Dynamic cornering lights (standard on 911 Turbo S models, optional for 911 Turbo models) offer particularly effective illumination of the road ahead, especially through curves. Sensors

continuously monitor the speed, lateral acceleration and steering lock and, from these variables, calculate the course of the curve. This determines the angle of illumination for the low beam lights, up to a maximum of 15 degrees. On twisting roads, this means the course of the road and obstacles can be seen earlier by the driver.

The lighting concept also benefits from the latest technology, in the form of high-performance LEDs for the horizontal front indicators and also for the separate daytime running lights, the taillights and the third brake light in the rear wing.

In addition to the distinctive look that makes the car very recognisable, the lighting also provides high illuminating power. The brake lights also respond very quickly, meaning that following traffic is alerted sooner. Plus the lighting saves energy, is environmentally sound and has a longer service life in comparison to conventional bulbs.

When the vehicle is opened or closed using the key remote, the ‘Welcome Home’ lighting function automatically switches on the LED daytime running lights.

Two additional lights inside each door ensure you see and are seen better when getting into and out of the car.
