Class supercar Porsche 918 Spyder_news car.

 

Owning the most advanced technology, the most expensive, both 918 Spyder is capable of racing rebellion, but also exemplary as electric vehicles.After 2 years from the first appearance, owns 918 power block beyond expectations. At the 2010 Geneva auto show, the new car has 715 horsepower, a year later, this figure was up 767 horsepower. Many said that power hitting just 800 horsepower, but the value that Porsche announced to reach 887 horsepower.
918 Spyder has three separate power source, a V8 engine capacity of 4.6 liter capacity 608 hp mid-set. This is one of the samples used on the V8 car race (RS Spyder LMP2), which can reach speeds of 9,150 r / min. Support through 5 Differential V8 is 154 hp motor mounted next booking of 127 horsepower.

After the motor is part of the hybrid system. It can independently transmit torque to the rear axle or in combination with an internal combustion engine. In contrast to the internal combustion engine can also power transmission to the rear axle via independent PDK 7-speed gearbox. Motor with independent front drivetrain follows. Torque transmitted to the front wheels via fixed transmission ratio. Separated from the motor when the car in high speed.
Block lithium-ion battery capacity 6.8 kWh, liquid-cooled, can be recharged in 25 minutes with a quick charger hits, 2 hours with voltage 240 V, 7 hours with a voltage of 110 V.
The combination of three sources of motivation created 5 operating modes. 918 Spyder is just as likely rebellious race car fuel thirsty, just like electric car model. The driver can select the mode on the control panel mounted on the steering wheel.
E-Power is the default mode at startup. Vehicles operated by reserve power, accelerates from 0 to 100 km / h in 7 seconds, a maximum speed of 150 km / h, operating within 29 km. V8 activated only when needed.
When the reserve power batteries to a certain reduction, automatic 918 Spyder Hybrid mode. 2 electric motors working in conjunction with the V8 engine to reduce fuel consumption max.
Sport Hybrid and Race Mode Hybrid uses both gasoline and electricity, but they work with the target operation, ignore performance. Race Mode seek more optimal performance, engine working under severe load, recharge the battery when the driver does not use its full capacity. Charging process is shortened so that the motor is energized.
Last mode works in conjunction with Race mode. Button "Hot Lap" between the red will change everything, in any given situation the remaining energy from the battery is rumored move to the motor to produce the fastest performance.
Porsche Active System 918 aerodynamic help better adapted to the driving mode. In Race mode and the Hot Lap, tilt system rear wing to increase the tire pressure down the road. 2 front wing open floor increase pressure for the front wheels.
Sport mode, steering angle and the lid down on the floor to close down and open sump at high speed. At E-Mode mode, and Hybrid, the goal is to reduce air resistance most, retractable spoiler in, underfloor branches, and the inlet cavity with closed engine cooling.
Rear drive system operation within 3 degrees, 918 have been allowed flexibility. Low speeds, the rear wheels rotate in the opposite direction to the front wheels go faster cornering, more accurately, reduce turnaround radius. High-speed, rear-wheel steering system and front wheel to increase dimensional stability.
From the rear, large exhaust placed high is what the car can not be ignored. Set immediately after the engine, exhaust diversion duty when pouring out the quickest way to the engine radiator and battery. Not only that it also increases the robustness.
Weighing 1,685 kg, the 918 Spyder is not really superior to P1 LaFerrari and McLaren, but it retains a certain point. Body carbon monocoque, structural supports and side frames made of carbon fiber reinforced plastics combine with (CFRP). CFRP oil tanks, titanium connecting rod, crankshaft bearing steel lightweight engine also contributes to weight loss. Weight distribution ratio for the last 2 - after the 57/43.
Package option Weissach 918 Spyder will decrease by 40 kg due to magnesium wheels, remove some of the sound quality and a number of other factors. It includes staging eye-catching exterior carbon fiber, leather and Alcantara upholstery special, 6 point safety belt and interior upgrades.
In terms of total transmit power at the wheels, 918 Spyder classified under LaFerrari and McLaren P, but it features kinetic par.

The time Porsche has not updated the exhaust emissions of 918, but that does not mean small hybird system will create dense black smoke screen rear. It said 918 Spyder is designed with racing dynamics and low fuel consumption. In the past, each running 100 km 918 with 3 liters of fuel, giving 70 g of CO2 per 1 km.
The price of a Porsche 918 Spyder at the 2010 was announced as $ 845,000 if additional Weissach package will be $ 929,000.
