The core contains a Porsche 918 Spyder concept : It's racing technology breed excellent suitability for everyday use and maximum performance with minimum consumption . The task facing the super sports car for the next decade to provide the development team a very effective and powerful hybrid drive. The developed from scratch , starting accordance with white sheet of paper car, the team was able to come up with a concept without compromise. The whole car was designed for the hybrid drive. Thus, the 918 Spyder , the potential for a hybrid drive unprecedented step , the improved efficiency and performance you would not at the expense of the other parallel. This is an idea that is out of the Porsche 911 is the most successful sports car in the world for 50 years. In short, the 918 Spyder will act as a gene pool for future Porsche sports cars .
Reveals the 918 Spyder with close links with the motorsport in different ways. It was designed , developed and manufactured by Porsche engineers to build race cars , produced in conjunction with the series production specialists . There are many lessons learned from the development of the Porsche race car won for 24 - hour race at Le Mans in 2014 and thus integrated 918 Spyder - and vice versa. It is a tradition at Porsche racing car - the structural concept of the 918 Spyder as a rolling chassis base - base vehicle can be driven without a body. The concept comes from the V8 engine of the RS Spyder LMP2 race car. The supporting structure is the monocoque and subframe made of carbon fiber reinforced plastic. Porsche has many years of experience in high - regained strength , lightweight materials and the best results with the development of the 918 Spyder product line. In many parts of the super sports car comes from the manufacturers as suppliers have a proven record for motorsports vehicles.Hybrid drive offers advantages in terms of driving dynamics
The 918 Spyder is a central message of the campaign is a hybrid of Porsche driving dynamics and a non - compromise. A unique wheel combination of combustion engine and electric motor on the rear axle and the second electric motor at the front axle - Drivers may experience thanks to the whole campaign concept . It is based on information obtained during car race with the successful Porsche 911 GT3 R Hybrid . For this reason, the top drive being individually controllable Further, a new start-up strategies accelerated curves secure implementation, especially for curves. In addition, managed progress "surge " strategy of the electric drive power , so smart , for each sprint with maximum acceleration , the full power of the 918 Spyder by simply fully developed the gas pedal down. In short, the 918 Spyder can workout without motorsport drivers to experience the potential of advanced longitudinal and lateral dynamics.
Has the potential to be many records and the Porsche 918 Spyder to break . The current lap time for the Nordschleife of the Nürburgring 7:14 minutes. In this day and age of international journalists achieved during testing in September 2012 - more than a year before the start of production. The 918 Spyder prototype , ie about 20 seconds faster than the Porsche Carrera GT. The following additional test runs on the Nürburgring - Nordschleife. More importantly, the 918 Spyder outperforms previous models and competitors also extended effectiveness . As a plug - in hybrid vehicle , it is systematically dynamic performance racing machine with over 880 hp and low NEDC consumption of approximately three liters of fuel per 100 km better than most small cars now days . To sum it up : maximum Fahrspaßbei minimum consumption.Carbon monocoque lightweight construction ensures a low center of gravity
The 918 Spyder with state - of - the - best to achieve art technologies directly from racing , top performance. The supporting structure is made of carbon fiber , while reinforced plastic (CFRP ) for large torsional stiffness. Crash elements added to the front and rear to absorb and reduce the energy of the collision. The Fahrzeugleergewichtvon about 1640 kg ( " Weissach " package ) , low weight for outstanding performance hybrid vehicle class, the majority of most of this concept. The drive components and parts weighing more than 50 kg as low and as central as possible within the vehicle. This resulted in a rear end slightly biased axle load distribution of 57 per cent over the rear axle and 43 percent to the front axle, combined with a very low center of gravity at about the height . Wheel hubs, suitable for driving dynamics and low central location on the traction battery directly behind the driver not only supports the efforts to the masses targeted and lower the center of gravity , it also offers the best temperature conditions for optimal battery power capacity .Chassis race car genes and rear steering axle -
The chassis is a multi - connect the Porsche 918 Spyder motor sports inspired design , complete with auxiliary systems such as the system PASM adaptive shock absorbers and rear - axle steering . Basically, the system includes the electro- mechanical adjustment of each rear wheel . The speed adjustment - and lead sensitive steering angle up to three degrees in any direction. It is therefore possible to control the rear axle in the same direction as the front wheels , or against it. At low speeds , the system steers the rear wheels in the opposite direction of the front wheels. The curves makes direct , faster and more accurate , and it reduces the turning circle . At higher speeds , the system steers the rear wheels in the same direction as the front wheels . Significantly improve the stability of the rear when changing lanes quickly. The result is a very safe and stable handling .Porsche Active Aerodynamics ( PAA ) for different driving modes
Porsche Active Aerodynamics ( PAA ), a system of adjustable aerodynamic elements , the unique aerodynamics and variable; setting is automatically changed by optimum efficiency and maximum contact pressure is adjusted to the mode hybrid drive system. In " Race" mode retractable rear wing is set to produce a sharp angle high downforce on the rear axle. The spoiler between Flügelträgernin near the rear edge of the air stream and expanded. In addition, two adjustable flaps them. Underfloor - air in front of the front axle, and provide guidance on types of air diffuser underbody structure This also creates a " floor effect" on the front axle .
In "Sport" mode , the system reduces the aerodynamic control of the angle of attack of the wing back a little , allowing a higher top speed . The spoiler extended. Lips close aerodynamic Unterbodenbereichund reduces drag and increases also accessible vehicles . Velocities in the mode "S" is the tax is completely designed for low air resistance ; retracted spoiler rear wing and the flaps and closed underbody .Adjustable air vents on the headlights round out the aerodynamic adaptive system . With the vehicle stationary and the " Race" mode and "Sport" is that they are for an optimal air supply open . In "E - Power" and " hybrid " they conclude to drive the car just to keep the air resistance to a minimum . You do not have to open until the car reaches speeds of about 130 km / h or at higher cooling demand.From comfortable to race - finished : five methods for three motor
The heart is the 918 Spyder concept car drive the distribution of power between the three power units; cooperation is regulated by a system of intelligent control . To take advantage of the best approaches defined Porsche developers the five operating modes can be activated by the " map switch" on the steering wheel , as well as in motor sports cars. Based on the pre - selected, use the 918 Spyder , the operational strategy and driver amplification case without intervention , so that the driver concentrate on the road.Quiet and elegant: "R - Power"
Mode is the standard mode , as long as the battery is sufficiently charged - when the vehicle is on the "Power E" started. Under ideal conditions, the 918 Spyder covering more than 30 km all-electric . In pure electric mode the 918 Spyder accelerates from 0 to 100 km / h in less than seven seconds and can reach speeds of up to 150 km / hr. mode, the engine is used only when necessary. If the battery charge drops below a set value , at least , the vehicle automatically switches to hybrid mode .Efficient and convenient: " Hybrid"
Working in " hybrid " mode , the electric motor and combustion engine to alternately focus on maximum efficiency and minimum fuel consumption . The use of individual drive components as a function of the current driving situation and the desired capacity modulation. The hybrid mode is typically used for the fuel consumption -oriented driving style.Sporty and dynamic: " Hybrid Sports "In dynamic situations , you choose the 918 Spyder "Sport Hybrid " mode for power sources. Operation of the engine at a constant rate , the main driving force . Moreover, these carriers in the form of electric motor speed, or when the operating point of the engine to be optimized for better combustion efficiency. The focus is on the method performance and sporty driving at maximum speed .For fast laps : "Hybrid Race"
The "Hybrid Race" mode for maximum performance and sportier mode . The internal combustion engine is used primarily due to high load , and charging the battery when the driver is not at maximum capacity. Again , provided that the electric motor in the form of additional carrier density . In addition, the Appliance Program - Transfer of PDK in place for even sportier drive . the electric motor to deliver up to the maximum limit of the output power for optimum performance on the racetrack , are used. In this mode, there is a constant battery charge state , but it varies over the entire range of the charges. In contrast to the hybrid sports mode , the electric motor runs at the maximum Grenzleistungfür a short period of time to better speed . The increased power of the engine offset the battery charging robust. Electrical power is available , therefore , also with some very fast laps .For the pole position : "Hot Lap "
Published the "Hot Lap " button in the center of the map to change the last reserves of the 918 Spyder and can only be activated in the "Race Hybrid" mode. As quality method , this pushes the limits of their traction battery output power for a few quick laps. The method uses the full power in the battery.Main drive : The car race on an eight -cylinder engine
Generated liter eight- cylinder engine , 608 horsepower - The main source of driving 4.6 . The engine is derived directly from the drive unit to the successful RS Spyder, which explains why it can deliver speeds of up to 9150 engine rpm. As the race engine in the RS Spyder features, the drive unit 918 Spyder dry lubrication - oil tank and sump with separate oil production. Weight-saving components such as the oil tank into the subframe and air intake system of carbon fiber reinforced polymer integrated air filter box. Further extensive lightweight construction in features out as titanium connecting rods, thin - wall , low resolution - press the crankcase and cylinder heads , high - strength , lightweight steel crankshaft with 180 degree crank offset and extremely thin - System - alloy steel walls / nickel exhaust . Distinctive features of the V8 is that it no longer supports auxiliary systems , there are no outer belt drives and the motor is particularly compact.
Weight and performance optimizations achieved a capacity of approx. 132 hp / liter - the highest output per liter naturally aspirated engine of the Porsche - which is much higher than that ( 106 hp / l) and unpaid for natural aspirated engine is the Carrera GT.Unique racing car design heritage : Top- pipesIt is not only the performance but also the sound it makes to the emotionality of the 918 Spyder Stokes .
This is partly due to the pipes above the so-called : the tailpipes in the upper part of the back end to end just above the engine. Any other production car with this solution. Is the upper tubes ' heat dissipation optimal because the hot exhaust gases released by the shortest route , and is still the exhaust back pressure is low .
The design requires a new concept of thermodynamic air distribution. The HSI engine is the hot side inside cylinder is V , the Einlasskanalnach outside. There are other advantages: the engine compartment cooler. This is particularly advantageous for lithium-ion traction battery , such as . The best performance at temperatures between 20 and 40 degrees Celsius Therefore, less energy needs to be used for active cooling of the battery.Parallel powertrain : a hybrid model
The V8 engine in combination with a hybrid module , since the 918 Spyder is designed as a parallel hybrid like the present Hybridmodellevon Porsche. Basically, the module contains a 115 kW electric motor hybrid and separating clutch , which serves as a link to the internal combustion engine . Due to a parallel hybrid configuration , the Spyder 918 , by the internal combustion engine or electric drive or are driven together at the rear axle , either individually both . As is typical of Porsche supercar that has the power of the 918 Spyder was the rear axle over , and there is no direct mechanical connection to the front axle .Upside - Down for a low center of gravity : dual-clutch transmissionHandles seven - speed dual clutch transmission ( PDK) transmission power transmission to the rear axle.
The transmission is high - the sportiest version of the PDK considerable success , it was re-designed completely by the 918 Spyder and is further optimized for high performance. To ensure a low mounting position for a low center of gravity of the entire vehicle , the transmission "upside down" had rotated by rotating 180 degrees around its longitudinal axis , in contrast to other Porsche series. If there is no power on the rear axle is required, the two motors can be uncoupled from the separating clutch open and clutch PDK . This is the action behind the typical " idle " off the internal combustion engine Porsche hybrid drive.All independent campaign - Wheel: front axle with electric motor
On the front axle and the other independent electric motor with an output of about 95 kW. The electric drive unit drives the front wheels at a fixed ratio . A disconnect-type clutch disconnects the electric motor at high speed to prevent the motor from turning. Driving torque is controlled independently for each axis. This functionality makes the whole campaign - very more responsive wheel that offers great potential in terms of traction and driving dynamics .Lithium -ion battery with plug - in charging system
The electrical energy for the electric motor is stored by a lithium ion battery - Liquid - cooled consists of 312 individual cells with energy content of about seven kilowatt hours. The battery is the 918 Spyder the performance-based design in terms of loading capacity , so that the performance requirements of the electric motor can meet . The capacity and lifetime of the lithium ion - traction battery , is dependent upon several factors including the thermal conditions. Therefore, the battery is is the 918 Spyder liquid - cooled by their own cooling circuit. Is the global warranty period for the battery pull seven years.In order to supply it with energy , Porsche developed a new system with port plug- in vehicle charging and potential improved recovery . This allows the Fahrzeugladeanschlussin the B - pillar on the passenger side users connect to the network battery and charging it at home. The charge port is to buy the land standardized. The onboard charger is located near the battery pull . It converts the AC to DC power supply with an output of 3.6 kW maximum fee .
