The Polyphony F686/M is a Formula One style car available in the NTSC version of Gran Turismo 3: A-Spec. It is based on the 1986 Williams FW11 driven by Nigel Mansell to second place in the Formula One World Championship, with teammate Nelson Piquet winning the driver's title that year and helping Williams win the Constructor's Championship that year. The car is the most powerful of six Formula One style cars in the NTSC version, and among the best in the game in terms of acceleration and grip.
The F686/M is not available for purchase in Gran Turismo 3. It can be acquired as one of four prize cars from:
- Internally, the car is named "williams_fw11", alluding to the base car.
- Although the actual car used Mobil 1 fuel, the car carries Castrol sponsorship instead. However, the placement of Castrol text logos in the sidepod and rear wings matches the placement of Canon logos in the FW11.
