Toyota AA80E vs ZF 8HP70

Chaps and Chapettes

Wondering if someone can help me. I've recently been looking at the Lexus F range (ISF/RCF/GSF), and several reviews of them had people mentioning about the very long gearing. I went and had a look at the Toyota AA80E (Aisin TL-80SN) and looked to compare it to the infamous ZF 8HP70 (Jaguar F-Type). I had a look at the gear ratio comparisons, as well as the change between gears and got 2 interesting charts, as below





I know final drive will also play a part in this (2.937 in the Lexus and 2.56 in the Jaaaaaaaag), but I see what those 2 charts have made, but what I'm not sure is what they mean. I'm not mechanically minded, so if anyone could shed some light on whether they do mean anything in general terms, or if I'm being stupid I'd be really grateful.

Thanks

It means they really aren't that different.

Although presumably there is a deeper meaning to the enquiry ?

Well I don't know much about these things so I was trying to work out if there really is much of a difference between them as the reviews make them say.

It might just be down to the Jag being supercharged and having the extra torque to make it feel faster.
