The concept’s sophisticated plug-in hybrid drivetrain has also remained largely intact, though there have been some minor changes made for production. A race-bred 4.6-liter V-8 is paired with an electric motor and seven-speed PDK dual-clutch transmission and spins the rear axle, while a second electric motor is used to spin the front axle.
The engine produces 608 horsepower on its own and screams to 9,150 rpm. It is based on the design of the racing engine found in the successful RS Spyder Le Mans prototype and also features lightweight components made from carbon fiber. The two electric motors produce 154 horsepower (rear) and 127 horsepower (front), respectively. System output for the 918 Spyder is 887 horsepower and 940 pound-feet of torque.
These numbers are slightly down on those of the Ferrari LaFerrari and McLaren P1, however, the Porsche 918 Spyder has the added traction of all-wheel drive, in this case a through-the-road hybrid system. The Porsche also benefits from a four-wheel steering system, already showcased on the latest 2014 Porsche 911 Turbo.

For the track, there’s Race Hybrid, where both the engine and electric motors output their full capacity. However, there is an even more extreme mode, Hot Lap. Here, everything is turned to the max and the battery is no longer charged so that the combustion engine can focus purely on driving the wheels. This mode, as its name suggests, is designed for setting lap records.
Also aiding the 918 Spyder on the track is a trick aerodynamics system. Here, there are three modes, with the most potent being a Race mode. A spoiler positioned between the two wing supports near the trailing edge of the airflow extends. Furthermore, two adjustable air flaps are opened in the underfloor in front of the front axle, and they direct a portion of the air into the diffuser channels of the underbody structure, helping to increase downforce.
Double-wishbone suspension is fitted up front and a multilink setup is used in the rear, with adjustable dampers at both ends. An electro-mechanical setup is used for the steering and the brakes are carbon ceramic discs measure up to 16 inches in diameter.

For the 0-60 mph run, owners can expect the 918 Spyder to take just under 2.8 seconds, hit 124 mph in 7.9 seconds and pass 186 mph in 23 seconds. It is this last number that has performance fans wondering, as McLaren has quoted a time of 17 seconds for the 0-186 mph run and Ferrari a mindboggling figure of 15 seconds.
Like its drivetrain, the 918 Spyder’s interior is thoroughly modern, coming with several LED panels and a large center column trimmed in aluminum and glass and featuring numerous controls on a smartphone-like glass surface.
Pricing starts at $845,000.
