I've often wondered what all the names and acronyms mean on cars. Things like GT I thought was Grand Tourer but then what is GTi? I mean you can't call a Pug 106GTi a Grand Tourer?? Others are: RS - as in Ford, Porsche and Audi is it Rally Sport? VRS - Skoda XR - Ford and Peugeot TD = Turbo Diesel RX - Mazda GL - Many GLX - Many ST - Ford And many more. Anyone help with explanations?
