Porsche Communication Management with MP3 player and an electronic logbook

Porsche 911 Carrera 4 / Carrera 4SThe 911 Carrera 4 and Carrera 4S all-wheel-drive coupés further expand the 911 model fa-mily. These outstanding models in the range are indeed clearly recognisable at very first sight: The extra-fat rear wheels measuring 295/35 ZR 18 on the Carrera 4 and an even more impressive 305/30 ZR 19 on the Carrera 4S are encased by wheel arches extended far out to each side, widening the rear end of the car by no less than 44 millimetres or 1.73" overall.
Porsche Stability Management with even faster brakes The two four-wheel-drive models proudly boast modified Porsche Stability Management (PSM) comprising additional functions: The first point is that the brake system is filled prior to application of the brakes all-out, which eliminates the usual air gap between the brake pads and the brake disc, and makes stopping distances even shorter. The second point is that PSM also intervenes in a critical situation: If the driver presses down the brake pedal quickly, but not hard enough, the hydraulic pump will build up the extra pressure required in order to activate the ABS control mode on all four wheels and thus ensure optimum brake power. This additional pressure on the brakes is however decreased immediately if the driver does not increase pedal pressure himself or if he takes back the brake pedal. So even with a sporting style of motoring, the system offers that option to precisely "dose" the brakes so typical of Porsche. In their basic features, the brake systems on the 911 Carrera 4 and 911 Carrera 4S naturally maintain that supreme standard of the Porsche 911: The monobloc fixed-calliper brakes are made of aluminium and come in each case with four pistons as well as cross-drilled, inner-vented discs. As an option both the 911 Carrera 4 and Carrera 4S are available with the latest generation of PCCB Porsche Ceramic Composite Brakes. These ceramic brake discs weigh approximately 50 per cent less than brake discs of the same size made of me-tal, offering a rapid, superior and consistent response and keeping brake wear to a minimum. Simply outstanding: aerodynamics and suspension Despite the two wheel arches bulging out as genuine signs of power over the rear axle, the aerodynamic qualities of the new models in the 911 range remain truly outstanding: The drag coefficient of the 911 Carrera 4 is Cd = 0.30, with the Carrera 4S boasting an even more impressive Cd = 0.29. This difference results from the ground clearance of the S-mo-del lowered by 10 millimetres or almost 0.4 inches and therefore offering even better all-round aerodynamics thanks to the standard use in this case of PASM Porsche Active Sus-pension Management. This suspension available as an option on the 911 Carrera 4 comes with a more comfortable damper setting in the normal mode, but switches immediately to a particularly firm and taut setup as soon as the driver presses the sports button. In both modes, however, the set-up adjusts permanently to the driver's style of motoring and road conditions, thus switching to the most appropriate control map between the two basic modes within fractions of a se-cond, depending on the standard of dynamic performance the driver wishes to enjoy at any given point in time. The 911 Carrera 4 comes in standard trim with conventional suspension, but both models are available with a sports suspension lowering the entire car by 20 millimetres or 0.79" and featuring a mechanical transverse lock on the rear axle. Sports Chrono Package for the sports driver Porsche offers the optional Sports Chrono Package Plus for the particularly sports-minded driver on both four-wheel-drive models, giving various functions of the car a particularly dynamic setting. The program is activated by the sports button in the centre console, modi-fying the behaviour and characteristics of engine management, PSM Porsche Stability Management, and - if fitted - PASM Porsche Active Suspension Management. Less fuel consumption, greater safety: tyre pressure control as an option As an option Porsche's four-wheel-drive sports cars are available with TPC tyre pressure control. Apart from offering greater safety against possible tyre damage, TPC serves above all to avoid inconsistent or excessive tyre wear as well as excessive fuel consumption thanks to the simple verification of tyre pressure. An important safety factor is the warning function informing the driver of any excessive loss of pressure in the tyres: Whenever the pressure measured in one or several tyres drops 0.3 bar below the prescribed level the driver receives a signal before and after each trip. As of 0.5 bar a red warning signal comes on in the display while driving and the driver is warned additionally by a gong. Wide range of passive safety features It almost goes without saying that the driver and his passengers in the four-wheel-drive coupés benefit from Porsche's wide range of passive safety elements featured as standard, as on all other models in the current 911 series. The car's safety features include three-point inertiareel safety belts on all seats, complete with belt latch tensioners and belt force limiters at the front. The total range of six airbags is made up of two two-stage full-size frontal airbags as well as Porsche's progressive POSIP Side Impact Protection System comprising a thorax airbag on the outer side of the seat backrest as well as a head airbag in the door, a feature intro-duced by Porsche as the first manufacturer in the world. Stylish and sophisticated interior with an even wider range of features The interior follows the superior style and design already featured on the 911 Carrera Coupé and Cabriolet, a very attractive combination of two colours now available over and above the "basic" level of equipment in the two models: The bi-colour scheme is available in the three leather combinations Black/Terracotta, in Black/Stone Grey and in Black/Sand Beige. PCM Porsche Communication Management comes as a standard feature and is also able to play CDs with MP3-compressed music titles. As an option PCM may be supplemented by further modules such as a navigation system complete with a DVD player. Yet a further option is the electronic trip recorder able to record up to 1,500 different trips and meeting all the requirements made by the authorities - for example in Germany - of an automatic trip recorder system.

The Carrera 4 models are powered by
engines already well-known in the market: The 3.6-litre six-cylinder in the
911 Carrera 4 develops maximum output of 239 kW (325 bhp), the 3.8-litre
in the 911 Carrera 4S delivers an even more significant 261 kW (355 bhp).
This kind of power accelerates the 911 Carrera 4 to 100 km/h in 5.1 seconds,
giving the car a top speed of 280 km/h or 174 mph. Accelerating from 0 -
100 km/h in just 4.8 seconds and reaching a top speed of 288 km/h or 179
mph, the 911 Carrera 4S is an even more outstanding performer.
