Bold textPosted by someone else from here on (I couldn't figure out how to make my own post, sorry!): Its actually generally the later Diablos that weren't RWD since Audi took over in 1996.  Although the VT has always been AWD/4WD (I have no idea what the difference is if there is one!) and perhaps the only AWD/4WD Diablo (I'm not sure!) Audi began to produce more models of VT (i.e. the VT 6.0, VT 6.0 SE and the VT Millenium Roadster as well as the previously made VT and VT Roadster) because of their stupid beliefs about sensible 4WD being better than the more dangerous yet obviously more thrilling RWD mainly due to the danger factor!

Now all Lamborghinis made are AWD/4WD however and that's thanks to Audi who have Audified the entire Lamborghini model range in probably every way!  Oh well, at least Lamborghini were able to produce the Diablo SE30 Jota before it all went wroong...
