overdrive that allows you to travel at high speeds at lower rpms...thus saving gas etc. if you were going 130 mph in 5th ud maybe go like 6k rpm...but in overdrive u could do it in 4k rpms. well i jus made those numbers up but a z06 vette can do 171 mph at 4250 rpms in overdrive. but in a normal gear itd be redlining
