Porsche develops high-quality, innovative and durable products. With each new model generation, Porsche consistently sets new standards in quality, environmental compatibility and safety throughout the entire life cycle of all vehicles.
Increased efficiency & reduced consumption
A successful concept for more efficient driving is intelligent lightweight construction. At every point in the vehicle, the optimum material due to its properties is used. As a matter of principle, lightweight construction is consistently implemented at Porsche throughout the entire vehicle - this concept already has a long tradition through racing. For example, the use of light metals in the current generation of the 911 has been increased by a further eight percent, that of even lighter plastics by four percent. Particular attention is paid here to the mixed construction. The Rohkarossen of the new Panamera and the new Panamera Sport Turismo are also built in this intelligent multi-material mix. The designers in the body are focusing on light alloys in direct connection with a very wide range of steel alloys of different strength. In the field of drive components and chassis, the traditionally high proportion of light metal alloys is being continuously expanded. Recently, in some top models, such as the 911 GT2 RS, even components made of carbon are used. The use of lightweight construction materials is flanked by state-of-the-art development processes, with the help of which the solution with the greatest weight reduction can be realized for every material and every application. Thanks to the consistent implementation of lightweight construction in all areas, it was possible to reduce the weight of the third generation of the Cayenne by up to 65 kilograms, despite extended standard equipment.
The introduction of downsizing engines started at Porsche in the front-end motor vehicles and was consequently extended to the boxer engines in the next step. After the naturally aspirated engines with 3.4 liters and 3.8 liters displacement were replaced by turbocharged engines with 3.0 liter displacement in the current 911 Carrera, the completely newly developed units in the 718 Cayman and the 718 Boxster were not only reduced in size, but also changed from six to four-cylinder boxer. Nevertheless, performance and torque of the now 2.0-liter and 2.5-liter turbo engines also increased here. A key mechanism for reducing fuel consumption is shifting the operating point to specifically higher loads and lower speeds. The good efficiencies achieved are attributable to a new technology portfolio of turbocharged engines. The engines are equipped with turbocharging, direct injection with central injector position, VarioCam Plus with intake and exhaust camshaft adjustment and additional valve lift on the intake side. For friction reduction, a fully variable oil pump and a variable engine thermal management system are used. With the development of the new turbocharged V8 petrol engine, which was used for the first time in the new Panamera, downsizing was once again optimized. A displacement reduction from 4.8 liters to 4.0 liters made a significant contribution to reducing fuel consumption possible while at the same time increasing the performance and performance of the engines.
Porsche Doppelkupplungsgetriebe (PDK)
The eight-speed PDK was introduced to the market with the new generation of the Panamera. Compared to the already very good predecessor transmission, the new PDK unites apparently contradictory requirements such as comfort, performance and efficiency again at an increased level. In addition, the PDK offers optimum cost-effectiveness with regard to the drive variants used in the Panamera, thanks to the consistently developed modular system. Already in the concept phase, the development engineers have made it their task to construct the possibility of hybridization as an integral part of the new PDK. Thanks to the so-called 6 + 2 design, the transmission allows driving comfort, outstanding performance and a simultaneous reduction in fuel consumption. The first gear is designed for maximum starting performance, the top speed is achieved in sixth gear. The seventh and eighth gear as so-called overdrive gears serve the ride comfort and the consumption reduction. A product innovation of the PDK represents the demand-controlled hydraulic power supply of the transmission by means of an adjustment system pressure pump. With the help of these and numerous further optimization measures the transmission losses could be reduced by 28 Percent (in test cycle NEDC).
In conjunction with the Porsche Doppelkupplungsgetriebe (PDK) is a further consumption savings by means of so-called sailing possible. It is avoided by the decoupling of the engine whose braking effect. The vehicle can thus optimally exploit its kinetic energy and roll a longer distance. If the driver reduces the throttle or takes the throttle off, the PDK automatically disengages the engaged gear and the vehicle sails with minimum fuel consumption at idle speed until the kinetic energy for the desired speed is insufficient.
Direct fuel injection (DFI)
The gasoline direct injection of the current boxer engines was converted to a further increase in efficiency and emission reduction from lateral injector position to central injector position. Thus, the fuel wetting of the cylinder walls and also the open intake valves can now be avoided. Furthermore, the variability of the valve train, the combustion in the cylinder combustion chambers can be influenced even more targeted. In total, this results in significantly improved operating conditions in the respective cylinder. This leads to a higher efficiency and thus also to a reduced fuel consumption at higher power. In addition, this can significantly reduce the formation of pollutants already during combustion.
InnoDrive: Driving Strategy for Consumption-Optimized Driving
With new measures to reduce fuel consumption, on the one hand the spectrum of individual driving programs and, on the other hand, the operator complexity for the driver are increasing. For this reason, Porsche developed the InnoDrive assistance system for maximum efficiency, individual dynamics and maximum comfort. Based on navigation data, the system looks ahead to the route to be covered, gaining information for controlling the engine, transmission and brakes for consumption-optimized driving. The driver is guided through the InnoDrive high-end ACC system - with minimal consumption and high driving pleasure.
Hybridization & e-mobility
Hybridization and electromobility are considered to be key components when it comes to conserving resources and reducing energy consumption and emissions. Porsche combines sportiness with the highest technological standards in its vehicles. This has been shown in the years 2015 to 2017 including the 919 Hybrid with its victories in the 24 Hours of Le Mans. The technically possible of the racetrack serves as a model for the standard sports cars in conjunction with the typical Porsche everyday usability. Porsche was the world's first premium manufacturer with three hybrid vehicles in the fleet - the Cayenne S E-Hybrid, the Panamera S E-Hybrid and the 918 Spyder. In the 2017 reporting year, Porsche also positioned a plug-in hybrid as the top model in a series for the first time with the Panamera Turbo S E-Hybrid. For the future, Porsche continues to focus on hybrid propulsion, but also on a purely electrically powered vehicle: With the Mission E, the company is breaking into a new age and underscoring its goal of being the leading sports car manufacturer in this field as well.
High-power charging network IONITY
With the founding of the joint venture IONITY in November 2017, the BMW Group, Daimler AG, Ford Motor Company and the Volkswagen Group set the course with Audi and Porsche for building the most efficient fast charging network for electric vehicles in Europe. The construction and operation of around 400 fast charging stations by 2020 are important steps to ensure long-distance electromobility and to establish it in the market. At such high-charging stations, the Porsche Mission E can be charged in just 15 minutes for a range of 400 kilometers.
Porsche Turbo Charging
In the future, the charging break of an electric vehicle will no longer or only minimally different from the usual tank break today: The driver parks his vehicle at a charging station and starts the charging process. Meanwhile, he uses the time for usual pause activities such as shopping in the kiosk, meal break or toilet. The payment of the shop can be made directly during the loading process.
Panamera 4 E-Hybrid
Electric and petrol engines form a harmonious whole in the Panamera 4 E-Hybrid right from the start. The 136 hp (100 kW) of the electric motor are available from the first tap on the accelerator pedal. Together with the 2.9-liter V6 twin turbo engine with 243 kW (330 hp) creates an impressive boost scenario in which the electric motor permanently provides additional thrust. The all-wheel Porsche creates a system output of 340 kW (462 hp) and 278 km / h in the top. In "Hybrid Auto" driving mode, the vehicle automatically switches and combines the two drive sources, guaranteeing the most efficient driving operation. Up to a range of 50 kilometers and a speed of 140 kilometers, the plug-in hybrid, which always starts in electric mode, is locally emission-free.In 4.6 seconds, the sporty luxury sedan accelerates from zero to 100 km / h. Out of the stand, 700 Newton meters of system torque are available. According to NEDC for plug-in hybrid models, the model consumes 2.5 l / 100 km and 15.9 kWh / 100 km of electrical energy. The brake system of the Panamera 4 E-Hybrid is the logical further development of the system in the 918 Spyder: a so-called 2-box system consisting of an electromechanical brake booster and a hybrid-capable hydraulic unit. The Panamera 4 E-Hybrid benefits from recuperation, ie the recovery of energy during the braking process via the generator operation of the electric machine. The active recuperation management decides whether the driver's braking request is generated via the torque of the electric motor and / or the conventional brake. The process is not noticeable to the driver, but allows a maximum level of recuperation and efficiency.
Panamera Turbo SE Hybrid
With the second hybrid variant of the Panamera, Porsche is positioning a plug-in hybrid as the top model in a series for the first time and underlining the great importance of electromobility for Porsche. The Panamera Turbo S E-Hybrid combines the four-liter V8 engine from the Panamera Turbo with an electric motor. The result is a system output of 500 kW / 680 hp and a superior power delivery: just above idle speed, 850 Nm of torque are available. This provides acceleration from zero to 100 km / h in 3.4 seconds and a top speed of 310 km / h. The four-wheel drive Panamera's boost strategy comes from the supercar 918 Spyder. The average fuel consumption in the New European Driving Cycle is 2.9 l / 100 km, and the Panamera top model can drive up to 50 kilometers purely on electric power. The electric motor is powered by a liquid-cooled lithium-ion battery with an energy content of 14.1 kWh. Within six hours, the rear-mounted high-voltage battery is fully charged via a 230-volt, ten-amp connection . As an alternative to the standard 3.6 kW charger, the Panamera uses the optional 7.2 kW on-board charger and a 230-volt 32-amp connection, so the battery is full after only 2.4 hours.
Cayenne S E-Hybrid
With the introduction of the Cayenne S E-Hybrid in September 2014, Porsche is playing a pioneering role in the premium SUV segment. The technical progress compared to the previous Cayenne S Hybrid is very clear: The performance of the electric drive has more than doubled, from 34 kW to 70 kW (95 hp) - while reducing the total consumption by almost 60 percent (from 8, 2 liters to 3.4 liters per 100 kilometers in the test cycle NEDC). Substantial improvements are also evident in the acceleration, range and top speed of 125 km / h in electric driving. The Cayenne S E-Hybrid has a lithium-ion traction battery with an energy content of currently 10.8 kWh - previously it was a nickel-metal hydride battery with 1.7 kWh. Depending on the driving style, 18 to 36 kilometers of purely electric driving are possible. A large part of everyday driving can thus be covered in many cases without fuel consumption and without local emissions. As the most environmentally friendly vehicle in its class, the Cayenne S E-Hybrid was honored by the trade magazine Auto Test and the independent Institute for Environmental Research as "winner in green 2017" in the year under review.
Electric concept study Mission E: tribute to tomorrow
At the beginning of December 2015, the Porsche AG Supervisory Board gave the green light for the construction of the concept study Mission E, which celebrated its premiere at the Frankfurt Motor Show IAA just three months earlier. The project shows what the first purely electrically powered sports car in brand history can look like. It meets all the requirements of a Porsche: performance and efficiency, driving dynamics and practicality. Based on revolutionary technology, the mission E is accelerated by two permanent-magnet synchronous motors (PSM) with zero emissions and recovers energy during braking. There are two PSM machines in the concept study Mission E, one on each axis. In this way, they convert the electrical energy into propulsion efficiently, evenly and with high continuous power. Together, the electric motors make over 440 kW (600 hp) and accelerate the electric sports car in less than 3.5 seconds to 100 and in less than twelve seconds to 200 km / h.
In addition to the athletic performance requirements of Mission E, the topics of charging time and range are of great importance for electromobility. Here, too, typical Porsche requirements are met: the range of the concept study is more than 500 kilometers thanks to a high-dimensioned lithium-ion battery. A 15-minute charge break is enough to recharge 80 percent of the energy. For this, Porsche has taken a new path and with its turbo charging concept doubled the usual charging voltage to 800 volts.
Longevity, materials & recycling
More than two-thirds of all 911s ever built are still on the road today. Among other things, this is due to the long-lasting and low-wear materials, which reduce the maintenance of a Porsche vehicle to a minimum. Basically, it is Porsche's concern to achieve a constant interval extension during maintenance, for example when changing the oil filter. The total cost of materials for the maintenance of a vehicle during its life decreases.
All larger plastic components used are labeled with their material designation for later sorted recycling. Wherever they meet the high technical requirements, plastic recyclates can be used as a substitute for new material.
Porsche has set the legal and internal requirements for product development and design that is suitable for exploitation in its own standard, the Porsche Standard "PN 1002". It serves, together with other existing standards, to achieve maximum environmental compatibility together with the suppliers and their subcontractors. The implementation is checked by Porsche in disassembly studies on real vehicles. Under realistic working conditions and with an original recycling tool, a deactivation of the pyrotechnic components that is safe for the employees, a quick and complete draining of fluid-carrying components such as the tank and the dismantling of components for reuse is checked. A Porsche vehicle is therefore 95 percent recyclable and 85 percent recyclable.
The Porsche vehicle features with a high performance potential in the transmission of power between tires and road surface offer high lateral acceleration reserves and short braking distances.Functions of integral safety with Porsche-typical character promote the sovereignty of the driver, who is actively involved in the control circuit driver-vehicle environment. In addition, Porsche vehicles offer a high potential for occupant protection through the optimized interaction of vehicle structure and restraint systems.
Porsche Stability Management (PSM)
Porsche Stability Management (PSM), which is standard in all Porsche models, is responsible for maintaining stability and traction in the dynamic driving limits and in unforeseeable, critical driving situations. Numerous sensors determine this while driving uninterrupted direction, lateral acceleration and driving and yawing speed of the vehicle. The PSM calculates the actual direction of movement from the collected data. If this deviates from the desired lane, the control system initiates targeted braking processes on individual wheels and thus enables stabilization of the vehicle. Even when accelerating on different surfaces, the PSM's Auto Brake Differential (ABD) and Traction Control (ASR) features enhance traction for agility, control and safety. If, during a drive with the control system switched off, a critical driving situation occurs, the driver can activate the function of the PSM by pressing the brake strongly. The anti-lock braking system must be activated with it.
The brakes are as important at Porsche as the engines or the suspension. With a strong driving performance, a high braking performance is indispensable. For example, the S models of the 718 Boxster, 718 Cayman, and 911 have front and rear wheels that are ten or fifteen millimeters larger than the base model. To ensure the best braking performance, all Porsche models are equipped with internally ventilated brake discs. The brake discs with hole or groove structure also provide improved wet response.
The best available brake technology is the optional Porsche Ceramic Composite Brake (PCCB). The perforated ceramic composite brake discs have a significantly higher surface hardness and a larger diameter - for the 911, for example, 410 millimeters at the front axle and 390 millimeters at the rear axle - and thus enable a particularly high braking performance. Compared to the cast iron brake, the PCCB is characterized by a significantly lower weight. The high fading stability of the PCCB also increases the safety during repeated braking from high speed.
To enable the best possible illumination of the road in the dark and in difficult weather conditions, Porsche has developed special lighting concepts for its vehicles. The models of the 911, Panamera and Cayenne as well as the 718 Boxster S have, for example, bi-xenon headlamps and a driving light assistant, which switches automatically from daytime running lights to dipped headlights as darkness falls. Another feature that significantly increases safety in critical driving situations is provided by the adaptive LED brake lights. In the case of emergency braking, these pulsate in their light intensity, when reached standstill, the hazard warning light is automatically activated. The subsequent traffic can thus be warned quickly and effectively of a dangerous situation.
The bi-xenon headlamps with additional halogen headlamps, headlamp cleaning system and automatic dynamic headlamp leveling ensure uniform illumination of the lane in both low beam and high beam. The dynamic cornering light turns the headlamps into the curve depending on the steering angle and driving speed. On the Panamera and Cayenne models, the static cornering light activates additional headlights to illuminate narrow curves or when turning. The Porsche Dynamic Light System (PDLS) also adjusts the light distribution of the speed. The bad weather light is activated together with the rear fog lamp. The result is increased safety - not just at night and in turns. The PDLS Plus offers two additional functions: The high-beam assistant detects the traffic ahead and oncoming traffic and automatically dimms the main beam. If the track is clear, the high beam is reactivated. By activating the static cornering light, intersections or indentations are better illuminated.
The LED headlights are technically and visually a complete new development. Each headlight module consists of two light housings each in a stepped arrangement. Integrated into this is the four-point daytime running light. The main advantages of the LED light are the particularly high luminosity and long life. LEDs consume very little energy and reduce eye fatigue, thanks to optimized near, side and long-distance illumination, as well as daylight-like color and low light scattering, less quickly than other systems.
Other security systems
The distance control tempostat regulates the speed depending on the distance to the vehicle in front. A radar sensor in the front section monitors the area up to 200 meters on the lane in front of the vehicle. If a certain speed is set and you approach a slower moving vehicle, the radar sensor detects this. The system reduces its own speed by removing the gas or by gently braking until a - previously adjustable - distance has been created. The vehicle now follows the vehicle in front at a reduced speed. If this slows down further, the adaptive cruise control continuously reduces the tempo - up to a standstill. When the road is clear again, the vehicle accelerates again to the originally set speed. The adjustable speed range extends from 30 km / h to 210 km / h. The integrated "stop-and-go" function enables - at the driver's request in a traffic jam situation - an automatic braking and restarting. Even more safety is ensured by the integrated Porsche Active Safe (PAS). If you drive too fast, you will be warned by an acoustic signal and a brake pressure. In addition, the system can amplify a driver-initiated braking.
The lane change assistant (SWA) uses radar sensors to monitor the area to the side behind the vehicle and the "blind spot". From a speed of 30 km / h and up to a speed of 250 km / h, the system, through an optical signal in the exterior mirrors, informs about vehicles that are approaching quickly from behind or are at a "blind spot". Especially on the highway, the lane change assistant increases comfort, but does not intervene in the vehicle guidance and can be deactivated at any time.
The speed limit display informs the driver about the current traffic situation. A camera detects speed limits, overtaking bans and their cancellations. If a traffic sign is not recognized, for example during heavy rain or darkness, the speed limit stored in the navigation module is automatically displayed. The driver can thereby devote full attention to the traffic.
Lane Departure Warning assists the driver on all multi-lane roads with lane boundary lines. A camera in the rearview mirror housing monitors the lane area in front of the vehicle. If you approach a boundary line or run the risk of leaving the lane without having set the turn signal, a warning tone warns you.
