On Thursday, October 28 at the official dealer of Porsche showroom in Russia "Sportcar Center hosted a presentation of new models Carrera 4 and Carrera 4S family 911. Representatives from leading publications writing about automotive topics, including journalist site AVTO.RU, gathered there that evening. After a brief introductory speech was broadcast promo, accompanied by detailed comments from experts. After the official part of a storefront showroom was fitted brand new Porsche 911 Carrera 4 and at the same time to the applause of the audience was charged matter concealed until the car, and the Carrera 4S appeared before the assembled journalists in all its glory. Remainder of the evening passed in a pleasant informal atmosphere in which journalists were able enough, "examine" the car. How, then, was the new Carrera 4 and what it differs from its predecessor - the rear-wheel drive Porsche 911 Carrera, demonstrated the previous year? Porsche has continued to steadily expand the model range of next-generation family 911: after the coupe and convertible Carrera 911 should be the start of production all-wheel drive Carrera 4 and Carrera 4S. New modifications differ from related models are not only technically but also visually. Let's start from the beginning. Located in the rear 3.6-liter six-cylinder boxer engine 911 Carrera 4 gives a maximum torque of 370 Nm at 4250 rpm and spends on average in the EU cycle of 11.3 liters per 100 kilometers. As a result, despite the four-wheel drive and a large mass, a new sports car consumes just 0.3 liters to more than the RWD model. The engine is equipped with a system of adjusting valve timing VarioCam Plus. It allows, on the one hand, to achieve optimal performance of power and torque, on the other hand, reduce fuel consumption, toxic emissions and improve the smoothness of the engine. Engine Porsche 911 Carrera 4S is an improved version of the 3.6-liter powerplant. In this case, the designers were not limited to increasing the diameter of the cylinder from 96 to 99 millimeters, but also resulted in the gas exchange of correspondence in line with the changed combustion chamber. First of all, high-torque 3.8-liter engine is 400 newton-meters, and its balanced characteristics provide improved ride quality and elasticity. Thus, in the range between 3000 and 7000 revolutions per minute before the driver has 350 Nm. Despite the increase in the working volume, torque and power, average fuel consumption of Carrera 4S in the EU cycle is just 11.8 litres/100 km and, as in the case of the 3.6-liter engine, a mere 0.3 liters more than the 911 Carrera S. Porsche 911 Carrera 4 can accelerate from 0 to 100 km / h in 5.1 seconds and reach a maximum speed of 280 km / h. And the 911 Carrera 4S, bi-xenon headlamps fitted as standard, accelerating to 100 km / h significantly more vigorously - for 4,8 seconds, top speed of this sport versions of 288 km / h. As with the rear-wheel drive Porsche 911, a six-speed manual gearbox is different low mass and high accuracy and precision switches. Alternatively, the mechanics are still invited to box Tiptronic S. The electronic control system box (EGS) are stored algorithms designed for different driving modes - from comfortable to extremely sporty. Porsche 911 with index 4 is a special form of dynamism: the two new coupe with balanced traction take turns at extremely high speed, which only allow the coupling properties of tires. Cars are stable in straight-line motion up to the maximum speed, but also have the potential implementation of the traction and directional stability on slippery road surfaces. These qualities are determined by wheel drive system that continuously transmits from 5% to 40% thrust to the front wheels. This distribution of power provides no inclination to the car to understeer and the demolition of the front axle at high speed cornering. Four-wheel drive Porsche 911 behaves on the road is extremely predictable, like a true sports car. For the distribution of power between the axles in the new Carrera 4 and Carrera 4S responsible multidisk viskomufty. To align the wheel speed front or rear axle are applied, respectively, front and rear cross-axle differentials, and viskomufty transmits engine thrust, which is located in the rear, the front axle. On the dynamic characteristics of the new 911 Carrera 4 Coupe also affects the modernized system stabilization Porsche PSM. A new generation of this system with improved algorithms and optimized components of antilock brake system familiar from rear-drive models, Carrera and Carrera S, in which PSM is installed as standard. The possibility of the stabilization system to reduce stopping distances and improved all-wheel drive models, thanks to its two new functions, which utilize electronics in critical situations. One of these innovations is that the PSM in advance increases the pressure in the hydraulic system, which helps reduce stopping distances during an emergency deceleration. When the driver quickly removes the foot off the accelerator, as usually happens before the braking, the system immediately increases the pressure of brake fluid and thereby eliminating the gap between the discs and pads. Thus, when the driver begins to press the brake pedal pad is almost close contact with the discs. On vehicles equipped with the optional sports package Chrono, pressing «Sport» off and PSM system does no longer interfere in the process of inhibition. As optional equipment on new 911 Carrera 4 Coupe and 911 Carrera 4S can be installed brake system with discs of a composite ceramic of the last generation - his own development company Porsche (PCCB). Perforated and internally ventilated ceramic discs 350 mm diameter weigh 50 percent less than the brake discs of the same size of the metal and reduce unsprung weight of more powerful 4S at 14 kg. Ceramic brake discs that achieve the very high and, most importantly, a constant friction coefficient. Compared with metal discs they wear out very slowly due to the extremely high hardness of the surface layer of ceramic composite. Thus, prolonged and life of the brakes, which also guaranteed corrosion-resistant material used. During the height of the clearance system is responsible for active management suspension, PASM (Porsche Active Suspension Management), mounted on the Carrera 4S in the base, and the Carrera 4 - as an option. Active suspension system also compensates for the adverse aerodynamic effects of wider tires model S. Another aerodynamic feature all-wheel drive models little noticeable: for ventilation of the front axle drive in a continuous veneer bottoms are special geometrically adjusted pear-shaped holes, which provide unobstructed airflow and give it an additional acceleration (ventilation elements of this type were developed by NASA - National Aeronautics and Space Administration USA). Intensive cooling is necessary to maintain the viscosity and stability of silicone fluid in viskomufty. Both new models feature a wider track rear wheels: 14 mm R18 tires on 32 mm with 19-inch tires. On the one hand, this is a consequence of wider wheels and tires, on the other - a smaller place. Now the serial 18-inch rear wheels Carrera 4 and 19-inch on Carrera 4S are departures ET 1951 (911 Carrera: ET 1958, 911 Carrera S: ET 67). Because the reference points of tires are now further apart, the car lurches smaller and has a greater potential for lateral acceleration. The front axle wheel-drive coupe installed wheels and tires of the same size as the model for zadneprivodnye: 8J x 18 with tires 235/40 ZR 18 on the 911 Carrera 4 and 8J x 19 with 235/35 ZR 19 tires on the 911 Carrera4S. As an option, you can order and 19-inch wheels with special discs Carrera Classic, SportDesign Carrera Sport. Fuel tank capacity is 67 liters of new products, which is 3 liters more than the rear-wheel drive 911 Carrera. Trunk, which previously housed the spare wheel is a new form, and its volume is now at 105 liters, provides room for two suitcases. New generation Porsche 911 instead of a spare wheel or dokatki "is equipped with a tire repair kit, which includes a compressor, a sealant, a towing loop, a set of onboard tools and adapter bolt sekretok. This set is compactly located under the boot floor in the voids between elements of supporting structure. The driver and passenger of a new four-wheel drive coupe can also rely on additional elements of passive safety features are fitted as standard, as in all other modern models of the Porsche 911. These include three-point automatic seat belts on all seats, belt tensioners in front and belt force limiters. Six airbags include two full-size front airbags with two stages of operation and innovative passive safety systems to protect against side impacts POSIP (Porsche Side Impact Protection). In the case of a serious accident two levels of frontal airbags triggered within a few milliseconds and catch the driver and passengers with an intensity corresponding to the force of impact. The system additionally includes POSIP cushion to protect the chest on the outside of the seatback and cushion the door for head protection, which uses a Porsche for the first time in the world. Side impact a flat pillow for head protection of almost eight liters revealed upward and effectively protects the head from hitting the side window or other items. Interior design follows the traditions of design, already known for coupe and cabriolet 911 Carrera. Particular attention is paid to the combination of colors and materials. Thus, the surface of materials with extremely high quality finish and very pleasant to the touch. Both models in the base leather trimmed gear lever, steering wheel, handbrake lever, the lid storage compartments in the center console compartment lid for small items at the door and door handles. Additionally, the middle part, the side bolsters and headrests front seats are upholstered in embossed leather. Headliner is made of Alcantara. On the Carrera 4S established sports steering wheel, aluminum dials of the instrument panel and painted an aluminum interior details, such as air deflectors and front of the laths. As an individual interior design to the Carrera 4 and Carrera 4S for the first time, and with the new model year on all models of Porsche 911 Series 997, offers an attractive two-tone leather trim three options: black / terracotta, restrained mix of "black / gray and contrast" black / beige. Alternatively, the adjustable height and reach three-spoke steering wheel on the Carrera 4 and sports steering wheel on the Carrera 4S, you can choose a multifunction steering wheel. Depending on the configuration with six function buttons on the steering wheel you can control important functions of the audio, navigation system and telephone. The proposed custom seats with electric can be programmed individually using the memory driver's seat. On the sports seats are also offered as an option, a 50 percent increased lateral support, and adaptive sports seats adjustment allows each driver to individually adjust and program the position of the side rollers cushion and backrest. Four-wheel drive coupe in the base also have communications center (PCM), which now plays CDs with recorded music format MP3. PCM as an option can now be expanded with additional modules, such as a navigation system with DVD-drive or a telephone module GSM. In addition to the basic configuration elements, such as climate control with a combined cabin air filters, alarm system and a package of Sound Package Plus with a tape recorder, CD-player and nine speakers, personality, Porsche 911 Carrera 4 and Carrera 4S can be given through a wide range of additional equipment. This includes, for example, surround sound system BOSE, parking assistance system, which is using ultrasound measures the distance to obstacles and warns the driver about the danger zoom, and even programmable HomeLink. This built-in garage door opening system can replace up to three hand-held transmitters, including lighting systems and alarms. Other options are two-position steel electric sunroof and trunk to be installed on the roof. It only remains to add that the price of the Carrera 4 coupe will be € 107,000, convertible - € 120 000. Cost coupe and convertible Porsche 911 Carrera 4S in the base will be equal to € 120,000 and € 133,000 respectively.
