Fastest Car: The Mitsubishi GTO twin turbo fully modified puts out 944 hp(thats with a stage IV turbo) Submission: Chris (PMPN8EZ@webtv.net) Alternate Fastest Car: The Actual Fastest car in Gran Turismo is the Toyota Supra. Why you ask, because it doesn't put out as much horse power as the skyline or GTO do and it aslo isn't 4wd. Well trust me on this, if you go to the testing tracks and go for the top speed ring, after a few modifications to the suspension, aerodynamics, final drive and gear ratios you should be able to get the supra up around 422km per hour. (obviously this is after modifing the supra with every thing turbo, exhaust etc.) I have tried with the skyline and GTO and can only seam to achieve very low 400s to 408s. Try it......!!
