The perfect balance of internal and external, the most effective form of body and strong, hardy engine — what do you need from the car? Oh yes. Acceleration to 100 km / h in less than three seconds. Porsche 911 Turbo S. Done.
Taking into account the entire model line, the new 911 second-generation version of the 991 is already the 8th version of the car, whose history began in 1973.
43 years ago was released the first version of the Porsche 911 in 930. It was the first production sports car with a turbocharged three-liter engine with a power of 260 hp Its top speed was 250 km / h and acceleration to 100 km / h takes 5.5 seconds.
Since then, the model is constantly received various technical improvements, all of which were aimed at one thing: to create the most powerful, most dynamic, most balanced of all available car buyer. Such technical solutions can be attributed the appearance of the second generation intercooler, in 1990 there was the catalyst in 1995 — double turbocharging, in the 2000s to replace the air it is liquid cooled. Over the years it's been revolutionary solutions that are initially tested and used on racing cars, and later after improvements and modifications installed and civilian. For example, well-known version of the GT2 was initially a symbol racing class, as cars with this index was constructed of 60 pieces for the homologation and the possibility of performances in races. But very soon, their demand has meant that they have been transformed into a specific model, which was produced for sale.
The new Porsche 911 is a second generation version of the 991, which was first published in 2013. It is interesting that this date coincides with another very significant overseas: Porsche announced that after 16-year hiatus, they returned to the big races and racing prototypes prepared to participate in 24 hours of Lehman in particular and the World Championship of Endurance in general. For this purpose was developed almost perfect Porsche 919 Hybrid, which revealed its civilian incarnation of the supercar Porsche 918 Hybryd. Technologies developed for and work out on the race track, got its application in the civilian version of 919. They later spread even wider, and moved to 911.
Let them a bit, but it can be called a good trend. In addition to the relevance they are also aesthetic load. For example — wheels with a central nut or additional acceleration mode button, acting on the principle of using the stored energy when the vehicle is in use when driving maximum power for 20 seconds. This magic button, available in version 911 Turbo S, an excellent tool to track for overtaking.
Outwardly from the previous generation car is slightly different. The company has traditionally minor design changes account for only one thing: that even the most effective form was developed for the vehicle, and any subsequent changes can be made based on any of the technical necessities, or as an opportunity to freshen up slightly overall appearance.
But from a technical point of view, about 911 can talk endlessly. This is what we have talked at length with the director of after-sales service «Porsche Russland» OOO Dmitry Orlov. Here is what he said:
«Technical differences start with the little things. For example, some very elegant solutions proposed for the new engine. One of them — otherwise the inner coating of aluminum cylinders. The new engine is no longer silicon, as it was before, and metal and concrete — iron. Due to the higher porosity of the material surface is a better retention of oil and as a consequence — less loss through friction.
We modify and adjust the timing. Or rather, we did not change, but added it is not only the intake, but also in the production. Nozzles are now located in the middle of the combustion chamber and the fuel pressure therein is raised to 250 atm (more than 2-fold compared with the previous value). This is to improve the efficiency of engine operation — the higher the pressure, the better the air-fuel mixture, thereby increasing the efficiency, power and engine efficiency.
Invented engineers and another elegant solution for quick warm-up of the engine at cold start: coolant is not supplied to the engine until it reaches the desired temperature. Then open the pump lock, and the process enters the working phase. "
All these little things affect the capacity and efficiency of motors and, by the way, bring a very tangible result. The new generation 911 in version 991 finally broke the 3-second mark of acceleration to 100 km / h. The new Porsche 911 Turbo S does it for 2.9 seconds!
Interesting news about the brand and have a box PDK transmission. Its optimization basically touched the two points. The first — is the emergence of an additional damper design two-mass flywheel, which stores energy that occurs when the torque fluctuation, and then releases it back into the system. This sophisticated device designed to smooth the fluctuation of torque at all times.
The second point — the virtual transmission. This is a regime that not only allows you to connect the two next transmission gear ratios, but also makes it possible to simultaneously slide two clutches. It is included in a time when the speed is not sufficient to go to the next gear, lowers turnover and insures the power and speed of the fall. This loss is less slippage of winning, which is achieved due to the operation of the engine at optimal speeds. This is an interesting feature.
Among other dynamic innovations, we note a few things:
1. Stability has been improved. For available modes added another: Pressing the button causes the stabilization, that stabilization is conventionally activated, but expands the possibilities for control by intervening in the process only as a last resort.
2. Active aerodynamics are now carried out by two members of the body — front and rear spoilers, which can be in different positions depending on the dynamic driving mode. However, the technical specialists of the company Porsche is not advised to use the position for maximum performance acceleration on the line, because This position ensures maximum downforce, which is good on the track.
3. And the third point — it is carrying out on the wheel driving mode switch, which used to be located on the center console. It helps the driver when driving, when you do not need to be distracted by the search for the right button.
With regard to the different support systems for the movement, including some security systems, it is very interesting to watch the dynamics of the development of the company from Stuttgart. Giving all the power to the development of cardinality and dynamic characteristics of the car, many of the technologies that have long been there in the account of other brands, they appear for the first time.
For example, the new 911 appeared, finally, the possibility of using the electro-hydraulic system to raise the front part of the body by 40 mm. Of course, this is not done to overcome off-road, but only for the arrival on the ramps of garages, however, in Russian conditions can be very useful, although it operates at speeds up to 40 km / h.
The same can be said about the new optional safety systems such as the next collision avoidance system, assistance system at evolution and others. The previous generation could not boast of them, however, the main thing in your Porsche is nevertheless not such driver assistance systems, and the opportunity to enjoy power and dynamics of this sports car. And this company from Stuttgart always provides the maximum.
