Some say the Diablo was the last proper Lamborghini (debatable…) because it was developed long before Audi bought the company and sterilised it with their sensible German-ness. The definitive poster-car was launched in 1990 as the Countach’s immediate successor, and remained in production until 2001 when it was replaced by the Murcielago.
Eleven years is a long time, so to keep things fresh Lambo kept fiddling with it. That means there are many different versions, so many that getting your ahead around which ones happened when, for what reason and how they differ is more difficult than actually driving one of the things.
So, we’ve done you a little guide. This gallery covers all the big ones (though Lambo naturally did special editions in runs of one or two cars), because to include them all would be a challenge too big even for us. Use the comments to argue about which one’s best. Ours is the fastest and most extreme, naturally.
