I got these stats from the Mazda website. What the heck is that Final Drive? The 6 doesn't have a 6 speed right.
Sorry if it looks unorganized, I arranged them but when I post it goes back like this.

Final drive is the ratio of the gear in the differential. (Same as rear end gear in RWD)

Reading Topic: Gear Ratios

I know there is no such thing as a stupid question but....

What do these numbers mean? I'm not exactly Mr. mechanic and I don't pay attention to gear ratio numbers - If I like how a car drives that's what matters.

So when it states that 1st gear ratio for the 4-cyl automatic is 2.816 what does this mean to me??

Thanks for the education.

Example:

engine is turning at 3000 RPM.
transmission in first gear reduces that to 1065 rpm (3000/2.816)
Final gear reduces that to 257 RPM (1065/4.147)

So in first gear while the engine is turning at 3000 RPM the wheels are turning 257 RPM

Thanks LBJay.

So, essentially what this tells me is that at the same engine rpm the wheels of the 4-cyl have to turn more often than in the v6 because each wheel revolution in the v6 is more powerful. Something like that.

Interesting. Almost too much for my non-mechanical brain.

I think I'll stick with driving what feels good as I always have. When my dad had a Regal Grand National in '87 I certainly didn't know anything about gear ratios - I just knew that I was the luckiest 16 year old in Toronto!
