Audi R8 GT Spyder 2012
- Audi R8 GT Spyder, 2012
Even lighter, even more powerful, even more captivating: The Audi R8 GT Spyder delivers breathtaking performance. The open-top flagship version of the high-performance sports car develops 412 kW (560 hp) and - thanks to Audi ultra - has trimmed a full 85 kilograms (187.39 lb) from an already low weight. The Audi R8 GT Spyder accelerates from zero to 100 km/h (62.14 mph) in 3.8 seconds and reaches a top speed of 317 km/h (196.97 mph).
One year ago, Audi unveiled the R8 GT in coupe form as the new flagship model of the R8 model line. It wasnt long before all 333 units in the limited series were sold out. Now the open-top version of the high-performance sports car is being launched, with production again capped at 333 units. Each car sports a tag with its individual number on the gear lever knob.
The Audi ultra lightweight technology is the key to the Audi R8 GT Spyders weight of just 1,640 kilograms (3,615.58 lb). Thats 85 kilograms (187.39 lb) less than its technical basis, the R8 Spyder 5.2 FSI quattro. The Audi Space Frame (ASF) body, consisting of cast nodes, extruded sections and aluminum panels, accounts for just 214 kilograms (471.79 lb) of the total weight. The body is assembled predominantly by hand in the R8 workshop at the Neckarsulm plant. Final assembly of the car takes place in the same way.
The engine frame is made of ultra-light magnesium; the long cover over the soft-top compartment and the large side panels at the rear are made of carbon fiber-reinforced polymer (CFRP). CFRP is also used for the modified front spoiler, the fixed rear spoiler and the new rear bumper. Together, these components provide a weight saving of 5.5 kilograms (12.13 lb).
Visual modifications accentuate the styling of the Audi R8 GT Spyder. These include add-on parts in contrasting titanium gray, a front splitter with a dual lip, flics at the sides of the front bumper, red GT badges, round exhaust tailpipes, an enlarged diffuser and dark LED tail lights in a clear-glass design. Audi offers an optional windshield frame in matt CFRP.
Audi engineers also trimmed weight from the technical components in the area of the transmission, wheels and brakes. In the interior, the bucket seats alone, with their chassis of glass fiber-reinforced polymer (GFRP), saved 31.5 kilograms (69.45 lb) of weight.
In classic Audi fashion, the Audi R8 GT Spyder features a lightweight fabric soft top that is extremely quiet and fully suitable for highway cruising. Its electrohydraulic drive brings it up or down in 19 seconds, even at speeds up to 50 km/h (31.07 mph). The extendible glass rear window is nestled in the bulkhead, separate from the soft top. Integrated in the bulkhead is a rollover protection system comprising two pretensioned plates.
Prodigious power: the drivetrain
The performance offered by the new top-of-the-line model in the R8 family is formidable. The 5.2-liter V10 with an aluminum crankcase draws its fuel from an FSI direct injection system. Dry-sump lubrication ensures a reliable supply of oil even under maximum lateral or straight-line acceleration.
With its modified electronic management, the long-stroke engine produces 540 Nm (398.28 lb-ft) of torque at 6,500 rpm, and its peak output is 412 kW (560 hp). Each unit of horsepower has only 2.93 kilograms (6.46 lb) to move.
The Audi R8 GT Spyder catapults from zero to 100 km/h (62.14 mph) in 3.8 seconds and reaches a top speed of 317 km/h (196.97 mph). In every situation, the engine impresses with its thrust and bite - and that unmistakable sound of an Audi ten-cylinder.
The Audi R8 GT Spyder comes standard with an automated six-speed R tronic transmission with two fully automatic modes. In the additional manual mode, the driver can shift gears using the paddles on the steering wheel or by flicking the joystick. At high load and revs, gear changes take only one-tenth of a second. The launch control program manages the starting sprint with high engine speed and precision-control of the tire slip.
The quattro permanent all-wheel drive has a strong rear-wheel bias, granted by the axle load distribution. If the situation calls for it, the system sends additional torque to the front axle. In tandem with the limited slip differential at the rear, it provides an added measure of traction, stability and cornering speed, giving it a strong lead over the rear-wheel-drive competition.
The suspension, too, is unrivaled in its performance. Aluminum double wishbones locate the wheels, and the rack-and-pinion power steering provides intimate contact with the road. Taut tuning lowers the body by approximately 10 millimeters (0.39 in). The open high-performance sports car has 19-inch wheels, with 235/35 tires up front and 295/30 tires at the rear. The large, lightweight carbon-fiber ceramic brake discs decelerate the car with supreme ease. The ESP stabilization program has a sport mode and can also be deactivated entirely.
Pure comfort: the interior and equipment
Great attention to detail is evident in the materials and workmanship inside the car. The salient aspect of the controls is their logically structured design. The open two-seater offers a roomy interior, and its front end can accommodate up to 100 liters (3.53 cu. ft) of cargo. The rear bulkhead houses three storage compartments.
The interior is black and can be adorned with stitching in a choice of titanium gray or crimson for added refinement. Alcantara upholstery comes standard - on the sport steering wheel and windshield frame, too.
Audi also offers leather in Fine Nappa quality. Numerous details - including white dials and R8 GT logos - provide classy accents. The distinctive R8 "monoposto," a large arch encircling the drivers cockpit, is made of matt CFRP.
Audi ultra requires no sacrifice on the part of Audi R8 GT Spyder owners. The standard equipment includes LED headlights, LED tail lights, an automatic air conditioning system, the navigation system plus, an alarm system and the driver information system with a built-in laptimer.
Audi also offers a sophisticated sound system from Bang & Olufsen and a Bluetooth interface including a seatbelt microphone for carrying on a phone conversation conveniently. Options specific to the R8 GT include bucket seats with a carbon-fiber composite chassis, matt CFRP applications and embroidered logos on the seat upholstery.
The Audi R8 GT Spyder will have a base price in Germany of 207,800 euros.

Porsche 918 Spyder Concept Review
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 Porsches 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 Porsches 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 Porsches 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 Porsches strategy is a milestone in the journey to the true power of mobility.

Porsche 918 Spyder Prototype 2012
- Porsche 918 Spyder Prototype, 2012
The Porsche 918 Spyder is on the road: Dr. Ing. h.c. F. Porsche AG, Stuttgart, has taken the driving trials of the super sports car of the future a step further with completion of the initial prototypes. The Porsche 918 Spyder go into production at the end of September 2013 as planned, with the first customers receiving their vehicles before 2013 is out. "What we are doing with the 918 Spyder is redefining driving fun, efficiency and performance," said Wolfgang Hatz, Member of the Executive Board Research and Development of Porsche AG.
The prototypes, their camouflage harking back to historical Porsche 917 racing cars, signal the final touches to the Porsche 918 Spyder. The focus is on the interplay between the highly sophisticated individual drive components. The combination of combustion engine and two independent electric motors - one on the front axle and one in the drive line, acting on the rear wheels - poses completely new demands on the development of the operating strategies. "They are therefore a critical component in this vehicle into which we have put all of our expertise and capacity for innovation," said Wolfgang Hatz. These operating strategies and the development of the software to go with them are one of Porsches core competences. Both of them have a major influence on the extreme driving fun to be had with the 918 Spyder and they make possible a unique combination of minimal fuel consumption and maximum performance. The initial results of the driving trials are in line with the high expectations placed on the Porsche 918 Spyder.
The super sports car is designed as a plug-in hybrid vehicle combining a high-performance combustion engine with cutting-edge electric motors for extraordinary performance: on the one hand, the dynamics of a racing machine boasting more than 770 hp, on the other hand, fuel consumption in the region of three litres per 100 kilometres. Moreover, Porsche is breaking yet more new ground with the technology demonstrator with spectacular solutions such as the full carbon fibre reinforced plastic (CFRP) monocoque with unit carrier, fully adaptive aerodynamics, adaptive rear-axle steering and the upward-venting "top pipes" exhaust system. In the process, the Porsche 918 Spyder is offering a glimpse of what Porsche Intelligent Performance may be capable of in future.
