The Polyphony F688/S is a Formula One styled car available in the NTSC version of Gran Turismo 3: A-Spec. It is based on the 1988 McLaren MP4/4 driven by Ayrton Senna (and Alain Prost) in the Formula One World Championship, dominating the whole season winning all but one races that season. It is one of six Formula One style cars in the NTSC version of the game. It is identical in specification to the PAL version's Polyphony002.
The F688/S is not available for purchase in Gran Turismo 3. It can be acquired as one of four prize cars from:
- The F688/S is shown to use Pirelli tires (and carries BP sponsorship, possibly using BP fuel as well), despite the source car, the MP4/4, using Goodyear tires and Shell fuel.
- Internally, the car is named "mclaren_mp4_4", alluding to the base car.
