as it so happens the 1.6 is actually still buildable on the Audi UK configurator for MY11 cars - not exactly sure what that means.
tbh as a former owner of the 1.6 MPI i wouldn't recommend it over the newer engines. on it's own it's not a bad lump, but compared to the newer ones i wouldn't bother with it.
the webbie says 105bhp, which is 3bhp up on the 1.6. however it's only £120 more and you'll probably save that in fuel in the first year so it's a bit of a no brainer. in fact i think you'll save most of that on your road tax. and it's top speed is 4mph higher so i'd imagine the 1.2 can cope with the weight.
