Ever since the original Countach went on sale in 1974, Lamborghini has had a habit of designing some of the craziest-looking cars ever to be put into production. Whether they're low-slung wedges like the Diablo and Aventador, hulking SUVs along the lines of the LM002, or limited-run specials such as the Reventon, Veneno and Centenario, it seems Lamborghini's designers have always pushed the limits of what's acceptable on a road car. Italian designer Vittorio Serpetti would therefore make a mighty fine design chief at Lamborghini.

The reason for this presumption, you ask? It's simple - Serpetti's the man who brought us the Lamborghini Raton. It's claimed to be based on the same platform that underpins the Lamborghini Aventador (so presumably has the same 700-hp V12 engine and seven-speed paddleshift gearbox), and he's already shown how bonkers such a car would be. Now, though, Serpetti's revisited his Raton by giving it a 'Vision Gran Turismo' makeover. The VGT inspiration isn't new to independent designers (for instance, we showed not so long ago a design student's take on a potential Seat VGT ), but what makes his Raton concept stand out to us is that it takes an already incredibly barmy shape and makes it even more extraordinary to look at.

On top of the wedged proportions and Disco Volante-esque front wings, Serpetti's Raton Vision Gran Turismo features several outlandish flourishes over its 'standard' predecessor like the spoilers that sprout from the enclosed rear fenders, the engine cover that now flows smoothly into the bodywork and the more aggressive scattering of vents and air intakes. With all of these additions, you'd be forgiven for thinking there'd be no trace of the regular Raton it's based on, let alone the hypothetical donor Aventador - and yet you can, if you look ever so carefully. The glasshouse is perhaps the biggest giveaway, and the angular front fascia that is usually covered by the number plate has also been carried over virtually unscathed.

Which is certainly something that can't be said of the Veneno and Centenario - we actually quite liked how you could clearly tell the Reventon was based on the already rather badass Murcielago. Bigging up the Raton VGT won't put it into production anytime sooner, though, as it's purely a flight of fantasy for the time being. That is, unless a wealthy fan of Serpetti's work decides to pay Lamborghini a lot of money in exchange for an actual, fully realized, Aventador-based Raton.
