4. The 918 Spyder could pay tribute to the illustrious past of Porsche, but his real mission is to redefine the possibilities of supercar. Intelligent use of advanced technology works to eliminate the traditional conflict between performance and efficiency. Faster, and theoretically more fuel miser of any past Porsche, the 918 companies over the current expectations of hybrid technology to ensure that the driving fun and extreme performance continue to thrive. This is the Porsche to the age of environmental responsibility.
   
   Now that we have experienced almost a dozen laps is the soul of the 918 is finally available for sharing in the passenger seat of the Porsche test track in Leipzig and the driver. Here's what you need to know about one of the supercar fastest I've ever driven.
   
   You'll never be able to pop open the hood of this exotic supercar. The team of 918 engineers saved weight of hinges, locks, and prop systems required with a conventional engine cover. And then, opening the hood would reveal little more than the 608-hp, 4.6-liter V-8 pipe exhaust, catalytic converters bulky, and mufflers colossal because the motor itself is buried deep in the frame.
   
   

   Inconel Pipes Meet ceramic balls

   
   Minimize weight through the use of exotic materials is the best way to maximize performance and fuel efficiency without compromise. For this purpose, the structural core 918 is a passenger bath of resin injection molded composite bolted to a frame space that surrounds and supports the engine, gearbox, and the rear suspension. Integrating the structure and body panels mainly in carbon fiber, the brake rotors are ceramic carbon, the optional wheels are forged magnesium, the exhaust system is Inconel (a nickel-based alloy containing chromium, iron and other elements) , and the fuel tank is made of aluminum super-size. The engineering team has chased each gram, using ceramic balls to cut 18 ounces of wheel bearings of the optional package Weissach.
   
   Porsche says the 918 weighs 3616-3715 pounds. This is clear only when it represents the mass of two electric motors, the copper wiring, a battery material, and the second differential units needed to provide on-demand on all wheels. In the interest of agility, the heavy parts are unusually low in the chassis, resulting in a slightly higher center of gravity to the centers of the wheels, and a power distribution duplex 57/43 percent.
   
   

   Four-wheel steering and driving

   
   Automatically steering the rear wheels up to three degrees out of phase with the front wheels gives the 918 crispy, turn-fast response (less than 31 mph). To improve stability, the rear wheels turn in phase with the fronts at higher speeds.
   
   In contradiction to his person manchine, we found the 918 surprisingly easy to drive very quickly on the challenging circuit Leipzig. The car provides clear feedback through the quick ratio electrically assisted steering, manageable understeer in the midst of sweeping curves, and a fast reaction to counter steering when the rear wheels drift wide in response to a first, jab enthusiastic throttle. This is the super sports car with the good sense to help drivers of every caliber.
   
   Automatic clutch engagement during the launch control, four-wheel providing the push, and sticky Michelin Pilot Sport Cup 2 tires (size 265 / 35ZR-20 front, 325 / 30ZR-21 in the rear) so that there is virtually no wheelspin acceleration from standstill to 60 mph in a claimed (2.8 seconds). That's almost a full second faster than the Carrera GT.
