The 918 Spyder was designed to replace the Porsche Carrera GT as Porsche's newest top-of-the-line performance car. It combines a V8 engine with two electric motors, making it the first hybrid hypercar by Porsche. Only 918 units were built, giving part of the car's name.
Forget everything you have ever thought about hybrids before you consider the 918 Spyder. It is the culmination of years of research and technical prowess from the first company that ever sported a prancing horse on its badge. The 918 Spyder is the starting point of a new era of performance and has raised the bar of what can be expected of a car, even a hypercar. Nearly 900 combined horsepower from its 4.6-liter naturally-aspirated flat crank V8 and hybrid electrical system and built almost completely of carbon fiber make it a technological marvel. The 918 Spyder already set a production car lap record at Mazda Raceway Laguna Seca and shattered the production car record at the Nürburgring by 14 seconds. It is visually stunning in all regards and distinctly Porsche even though it looks like no other Porsche ever. The blank sheet of paper 918 designers started with produced innovations in every direction and convention was left by the wayside. The result is nothing less that the spark of a new generation of the highest performing vehicles the world has ever seen.
Designed by Michael Mauer, the Porsche 918 Spyder is powered with a 4.6L (4,593 cc) naturally aspirated V8 engine built on the same architecture as the one used in the Porsche RS Spyder Evo with the engine belts removed.
The V8 delivers 608 hp (453 kW) at 8,500 rpm and 389 ft·lb (527 N·m) of maximum torque and is supplemented by two electric motors delivering an additional 279 hp (208 kW), with one 154 hp (115 kW) electric motor driving the rear wheels in parallel with the engine and also serving as the main generator. This motor and engine deliver power to the rear axle through a seven-speed PDK gearbox. The front 125 hp (93 kW) electric motor directly drives the front axle and is decoupled by an electric clutch when not in use. The total output comes out as 887 hp (661 kW) and at least 829 ft·lb (1124 N·m) of torque.
A 312-cell, liquid-cooled 6.8 kWh lithium-ion battery appears behind the passenger cell. In addition to a plug-in charge port at the passenger-side B-pillar, the batteries are also charged by regenerative braking and excess output from the engine when the car is coasting. The V8 can recharge an empty battery on about two liters of fuel (0.53 US gallons). The supplied Porsche Universal Charger requires seven hours to charge the battery on a typical 110V household AC socket or two hours on a dedicated Charging Dock installed with a 240V industrial supply. An optional DC Speed Charging Station can fully recharge the battery in 25 minutes.
The 918 Spyder can operate under five different driving modes: E-Drive, which allows the car to run solely under battery power using the electric motors. Two hybrid modes (Hybrid and Race) utilize the engine and both electric motors to provide desired levels of economy, efficiency, and performance. In Race mode, a push-to-pass button initiates the Hot Lap setting, which delivers additional electrical power for use on the track. The 918 Spyder's chassis is a carbon fiber-reinforced monocoque, while the car uses electromechanical brakes. The car also uses active aerodynamics, with the rear wing folding up under heavy braking.
Porsche provided the 918 Spyder's performance figures as 0-60 mph (97 km/h) in 2.4 seconds, 0-124 mph (200 km/h) in 7.2 seconds, 0-186 mph (300 km/h) in 19.95 seconds, and a top speed exceeding 211 mph (340 km/h). The car can reach 200 mph (322 km/h) in 29.7 seconds.
Some models of the 918 come with the Weissach Package performance option, which includes visual modifications to reduce the car's weight by 88 lb (40 kg).
The Porsche 918 Spyder is one of the fastest-accelerating cars in the series, with 0-60 mph (97 km/h) occurring in 2.2 seconds and 0-100 mph (161 km/h) in 4.9 seconds, due to using an AWD drivetrain mixed with a hybrid powertrain. Only the Hoonigan Ford "Hoonicorn" Mustang and Ford Gymkhana 9 Focus RS RX are faster to 60 mph (97 km/h), reaching that speed in 1.8 and 1.9 seconds, respectively. While also having decent handling, the 918 shows moderately-pronounced understeer on twisty roads due to weighing 3692 lb (1675 kg) and lacking its unique four-wheel steering system, although it makes use of its electromechanical brakes, active aerodynamics, and AWD drivetrain to slow down to appropriate cornering speeds more quickly than its competitors.
In games prior to Forza Horizon 3, the 918 Spyder had a higher value than the Ferrari LaFerrari and McLaren P1 in the Forza series, with 850,000 CR (1,417 - 1,700 TK), even though the latter cars have a much higher price tag in real life.
This was changed in Forza Horizon 3 to have the LaFerrari and P1 priced at 1,500,000 CR and 1,350,000 CR, respectively.
The 918 Spyder's hardtop roof can be removed in ForzaVista. Just like with other cars with removable roofs, the 918's roof always stays on the car when driven.
September 18, 2013 (9/18/2013) was designated as Porsche 918 Day, a reference to its name.
The 918 Spyder's engine, named "4.6L V8 Hybrid" in-game, can be swapped onto the Porsche 959 and Carrera GT.
