The manual gearbox on the Contour is a 4.06:1 ratio......that is an excellent ratio for acceleration. The automatic gearbox is 3.92:1 which is also excellent. I don't think you need a different gear. For Mustangs you can get up to 5.30:1 (for killer accleration) or all the way down to 2.90:1 (for high top speeds). But those are for highly modified ones with TONS of HP.
