Gear ratios in catalogue?

[Bruce GT3]

Just been leafing through the new Leon brochure online and noticed that they seem to quote for 2 different final drives?

http://media.seat.co.uk/pdf/June_Leon_Spec12.pdf

They quote the usual ratios from 1st through 6th and reverse, and then another ratio with either "Group 1" or "Group 2"?

Anyone know what this means? I assume it's the final drive ratio and alternative's for certain markets?

I assume the mk2 uses a version of the 02M gearbox?

The 02M (as used in the mk1 LC, LCR and other VAG stuff) has two final drive paths, one for 1-4 and the other for 5&6 iirc. That'll be the group 1 and group 2 you are seeing.

It's an 02Q 'box, but running the gears through my gear calculator spreadsheet seems to give the right speeds for the ratios.... odd that it has 2 final drives though...

The two final-drive ratios are down to certain gears taking different paths through the box, as csd_19 says.

It messes with my brain a bit but my engineering-savvy colleague seems to understand it.

http://www.volkspage.net/technik/ssp/ssp/SSP_205.pdf gives information on the 02M, it'll show you the output paths through the two different final drives.
