What engine does the Porsche 918 use?
3 Answers
The Porsche 918 is equipped with a 4.6-liter V8 naturally aspirated engine, combined with a dual-motor hybrid system, and paired with a 7-speed dual-clutch transmission. This engine delivers a maximum power output of 447 kW and a peak torque of 500 Nm. It features direct fuel injection technology and utilizes an aluminum alloy cylinder head and block. The Porsche 918 has a body length of 4643 mm, width of 1940 mm, and height of 1167 mm, with a wheelbase of 2730 mm. It employs a mid-engine four-wheel-drive layout, with a double-wishbone independent front suspension and a multi-link independent rear suspension.
I previously researched the Porsche 918, and the most impressive thing about this car is its hybrid powertrain. The mid-mounted 4.6-liter V8 naturally aspirated engine sounds absolutely thrilling, capable of revving up to a 9,000 rpm redline and delivering 608 horsepower on its own. But the key lies in the additional three electric motors—two on the front axle, each producing 154 horsepower, and one on the rear axle with 129 horsepower. Combined, the entire system unleashes a狂暴的887 horsepower. Paired with a 7-speed PDK dual-clutch transmission, this results in a monster-like 2.6-second 0-100 km/h acceleration. The system also supports纯电driving for 25 kilometers, making it quite a surreal sight to see a supercar quietly gliding into the neighborhood.
Last week, while chatting with a friend who's into car modifications about the Porsche 918, I discovered its engine is far more fascinating than typical hybrids. The rear-mounted V8 engine incorporates Le Mans racing technology, with piston rods directly sourced from the 911 GT3 RSR race car, and a dry sump design that allows the body to sit even lower. What's even more mind-blowing is the electronic control system—the two independent front-wheel motors not only provide drive but also individually control torque for vector distribution, making it feel like invisible hands are helping steer through corners. The gasoline engine and electric motors work in harmony via a carbon fiber driveshaft, with a precision of 0.001 seconds during power source transitions. And if the battery runs flat, no worries—the gasoline engine can recharge it to 80% in just three minutes.
