This is a YT-2400 Outrider from the Star Wars universe, which we definitely knew for ourselves and aren’t simply quoting the builder in an effort to appear knowledgeable about sci-fi.
Built by aido k, the model uses around 4,000 pieces and weighs in at 5kg, which includes a neat lighting system to illuminate the engine.
There’s more superb imagery of the Outrider to see at aido’s album on Flickr – click the link above to something something dark side.
