Porsche 918 Spyder Concept Review

Porsche 918 Spyder concept combines high-tech racing features with electric mobility to offer a variety of attractive qualities. For example, it is intended to provide the level of emissions of just 70 grams CO2 per kilometer on fuel consumption of just three litres/100 kilometers (equal to about 78 miles per U.S. gallon), which is really remarkable, even for ultra-city car compact. This car, however, is designed to give the performance of a super sports car with acceleration from zero to 100 km / h in under 3.2 seconds, top speed 320 km / h (198 mph) and laps at the Nurburgring Nordschleife in a time of less than 7:30 minutes, even faster than the Porsche Carrera GT.
Porsche 918 Spyder is one of three Porsche-powered hybrid made their world debut at the Geneva Motor Show 2010. The trio - comprised of the new Porsche Cayenne S Hybrid SUV with a full parallel hybrid drive, 911 GT3 R hybrid race car with electric motors on the front axle and flywheel batteries, and high performance two-seater mid-engined Porsche 918 Spyder sports car with the technology plug-in hybrid - clearly demonstrates not only the bandwidth of the great new drive technologies, but also the innovative power of Porsche as a true pioneer in hybrid drive.
The concept of a Porsche 918 Spyder Porsche's philosophy of combining innovative technology with intelligent high-performance motor sport, with a classic yet modern design to make a statement that really convincing.
Innovative Powertrain combines race bred V8 engine with electric drive
This open two-seater is powered by a V8 engine developing at a rapid rate of more than 500 horsepower and maximum engine speed of 9200 revolutions per minute - as well as an electric motor at the front and rear axle with overall mechanical output of 218 hp (160 kW).
V8 combustion engine is the next step in the evolution of the 3.4-liter power unit has been very successful in the RS Spyder racing car and positioned amidships, forward of the rear axle, giving the car excellent balance and good overall performance-for the race track The main.
Power transmitted to the wheels via Porsche's seven-speed transmission-Doppelkupplungsgetriebe (PDK) which feeds electrical power drive systems of the rear axle. The front-wheel drive electric power wheels through a fixed transmission ratio.
Energy reservoir of liquid-cooled lithium-ion battery positioned behind the passenger cell. The great advantage of the plug-in hybrid is that the battery can be charged on the strength of normal tissue. Another thing is that the kinetic energy is converted into an electric vehicle and charge the battery when the brakes are applied, providing additional power for acceleration and dynamic.
The driver can choose between four different driving modes



 
A button on the steering wheel allows the driver to choose between four different modes: E-Drive mode to run the car in electric mode only, with a distance of up to 25 km or 16 miles. In hybrid mode, the Porsche 918 Spyder uses both electric motors and internal combustion engine in accordance with driving conditions and requirements, offering a variety of specific energy saving up to an extra-strong.
Sport Mode Hybrid uses two drives, but with an emphasis on performance. Most of the power going to the rear wheel drive, with torque vectoring is used to improve driving dynamics and more of the car.
In the course of hybrid drive systems are focused on pure performance with the highest standard of driving dynamics on the track, running at the limits of their power and dynamic output. With enough battery power, push-to-pass button feeds additional power supply (E-Boost), when overtaking or for better performance.
With a hybrid drive system offers a wide range of individual modes and applications, the Porsche 918 Spyder is able to achieve lap times comparable with horse racing cars, or very low emissions and high levels of fuel economy of a hybrid plug-in.
Body structure and advanced design provides more than just look good
Powertrain, body structure lighter than the Porsche 918 Spyder also carries the DNA of the car was taken directly from motorsport: a modular structure with monocoque carbon fiber reinforced plastic (CFP) and liberal use of magnesium and aluminum not only reduce weight below 1.490 kg or 3285 pounds, but also to ensure, thanks to the precision of your driving high levels of torsional rigidity.
Reminds us, a successful race cars such as Porsche's legendary 917 and the Porsche RS Spyder at this time, 918 Spyder, with a design concept so typical of Porsche evoke strong emotions. The combination of racing car dimensions, clearly structured design with perfectly balanced surfaces, and innovative details throughout, creating an ideal synthesis of form and function - following Porsche Design DNA.
The balance of sweet tradition and progress gives the car a powerful stance on the road. Variable aerodynamics, typical of Porsche, ensures both visionary and emphasizes in particular around the traditional rear spoiler. The striking rear hoods extending head restraints, in turn, not only to fill an aerodynamic function on the Porsche 918 Spyder, but also accommodate retractable air intakes with a ram air function.
High-tech interior offers a glimpse of the future



 
The driver and passenger are not only integrated into the contoured sport bucket seats, but also part of the cabin, which provides an efficient synthesis of functionality and ergonomic high-tech operation. In addition, the cockpit provides an overview of the architecture of the future potential of Porsche sports Super. Three free-standing circular calling for road speed (left), engine speed (middle) and energy management (right) seems to come directly from car racing in 60 years, showed that the unique philosophy of driver orientation so typical of Porsche.
Climbed into the front center console in a Porsche 918 Spyder and houses a touch screen for intuitive control functions of the car, used to reduce the amount of control look and maintain the principle of direct use.
Control units relevant to the driver mainly concentrated on three-wheel sports multifunction steering wheel while driving is equipped with a variable mode switch allows the driver to call the various training programs and serve as a push-to-pass button for E-stimulant. Lighting instruments, finally, varies from green to red oriented consumption patterns run the program focused on driving performance.
Porsche 918 Spyder concept also comes with innovative features such as range managers. Once activated on the central screen, Range Manager uses the map in the navigation system to present the range is the car able to cover, allowing the driver to influence the natural range over the appropriate choice of power and performance.
In urban areas Range Notification Manager environment also indicates whether the driver is able to achieve certain goals on electric power alone.
Applying this information and uses more information about availability and location specific charging power station, the driver is then able to choose his personal style of driving and the battery on the right and fill out a strategy.
Offering a unique combination of fuel consumption is very low, the highest performance and a long electric range, the concept of the Porsche 918 Spyder Porsche's strategy is a milestone in the journey to the true power of mobility.
