2013 Porsche Panamera 4S Extremely Powerful

The new 2013 Porsche Panamera 4S is equipped as standard with adaptive air suspension including Porsche Active Suspension Management (PASM). This combined system enhances both dynamic performance and comfort. It features a leveling system, ride-height adjustment, spring rate adjustment and electronic adjustment of damping forces. With the air suspension at Normal Level, the 2013 Panamera 4S already sits 0.39 in (10 mm) lower than other Panamera models and the suspension has a firmer setting. As soon as SPORT PLUS mode is selected, the suspension automatically drops to Low Level (0.59 in lower). At the same time, a harder spring rate is achieved through a reduction in the amount of air stored in the air suspension.

The manual lift function enables you to raise the vehicle body by 1.18 in (30 mm) to High Level to minimize the risk of grounding, e.g. on car park ramps.* The purpose of the leveling system is to keep the vehicle level constant automatically and regardless of load distribution. PASM is an electronic damping control system. It actively and continuously regulates damping forces according to driving style and road conditions for increased body stability and a more direct steering response. It is possible to select from three modes: Comfort, SPORT or SPORT PLUS. For you, this involves nothing more than the press of a button and you can feel the result: increased driving stability, more comfort and improved performance.

Fitted as standard in the 2013 Porsche Panamera 4S, Porsche Traction Management (PTM) comprises an active all-wheel drive with electronic and map-controlled multiplate clutch with Automatic Brake Differential (ABD) and Anti-Slip Regulation (ASR). The electronically controlled multiplate clutch regulates the fully variable distribution of drive force between the permanently driven rear axle and the front axle. Through continuous monitoring of driving conditions, the electronics are able to respond to a variety of situations. Sensors check, among other variables, the rotation speeds of all four wheels, the longitudinal and lateral acceleration of the vehicle, and the steering angle. If the rear wheels threaten to spin under acceleration, a greater proportion of drive force is distributed to the front by a more powerful engagement of the multiplate clutch. In addition, ASR reduces wheel slip.

When cornering, the front wheels only ever receive as much drive force as is necessary to guarantee optimum lateral stability. In this way, PTM, in interaction with Porsche Stability Management (PSM, p. 27) ensures that the perfect distribution of drive is achieved every time: whether on long straights, through tight corners, or on surfaces with different friction coefficients. In this situation, traction is additionally enhanced by the Automatic Brake Differential (ABD). Whenever the brake control systems are required to intervene, PTM decouples the front axle completely so that PSM interventions can take place at each individual wheel.

Precise and direct: describes a typical Porsche steering system with variable steering ratio. Around the straight-ahead position, such as during motorway driving, the ratio is less direct with no loss of agility or feedback from the road. When the steering wheel is turned further, the ratio becomes more direct, allowing easier cornering and parking. Servotronic, the speed-sensitive powersteering system, is available as an option. At high speeds, the steering is firm and responds with extreme precision while steering comfort remains as high as you would expect. At low speeds, Servotronic’s ratio adjusts for easy maneuvering and parking.

The 2013 Panamera 4S is an extremely powerful vehicle, which is why it comes equipped as standard with 19-inch Panamera Turbo wheels featuring a classic sporty design. Tire sizes 255/45 ZR 19 and 285/40 ZR 19 are fitted to the front and rear respectively. For a wider track, wheel spacers (5 mm) are fitted at the rear as standard. A selection of 19- or 20-inch wheels is available in our range of options. Alternatively, you can select a set of 19-inch all-season tires. A low-rolling resistance version of these tires is available as an option. These reduce fuel consumption and offer improved durability. Tire Pressure Monitoring System (TPMS), which is fitted as standard, sends warnings to the on-board computer’s display screen in the event of excessive pressure loss.

 PSM is an automatic control system that stabilizes the vehicle at the limits of dynamic driving performance. Sensors continuously monitor driving direction, speed, yaw velocity and lateral acceleration. Using this information, PSM computes the actual direction of motion. If this direction deviates from the desired course, PSM can, for example, initiate braking interventions targeted at individual wheels in order to stabilize the vehicle. Under acceleration on wet or low-grip road surfaces, PSM improves traction using the ABD (Automatic Brake Differential) and ASR (Anti-Slip Regulation) functions. For an even more involving driving experience, you always have the option to deactivate PSM. It is automatically reactivated, for your safety, only if you brake harder and either of the front wheels (in SPORT PLUS mode, both of the front wheels) requires ABS assistance. PSM comes with two additional functions: precharging of the brake system, enabling maximum braking power to be achieved much sooner; and brake assist, for maximum deceleration in a critical situation.

PDCC is available as an option for the Panamera 4S. This is an active anti-roll system that anticipates and significantly reduces lateral body movement during cornering maneuvers. In addition, it minimizes the lateral instability of the vehicle on uneven ground. The effect is
achieved with the aid of active anti-roll bars on the front and rear axles which respond to the current steering angle and lateral acceleration by producing a stabilizing force that precisely negates the roll of the body. PTV Plus combined with PDCC is a system that actively enhances vehicle dynamics and stability. Operating in conjunction with an electronically regulated rear differential lock, it works by varying the torque distribution to the rear wheels. To be more precise, this means that when the car is driven assertively into a corner, moderate brake pressure is applied to the inside rear wheel. Consequently, a greater amount of drive force is distributed to the outside rear wheel, inducing an additional rotational pulse (yaw movement) around the vehicle’s vertical axis.


This results in a direct and sporty steering action as the car enters the corner. At low and medium vehicle speeds, PTV Plus significantly increases agility and steering precision. At high speeds and when accelerating out of corners, the electronically regulated rear differential lock ensures greater driving stability. It also serves to improve traction at the rear wheels on road surfaces with varying levels of grip, in the wet and on snow. For the driver, this means remarkable lateral vehicle stability, optimum traction as well as a high degree of agility at every speed with precise steering and stable load transfer characteristics. In short, it offers pure driving pleasure.
