Just yesterday, Lamborghini ->ke44 announced the production of the last Gallardo and today it has already started to tease its successor. The Italian company launched a new microsite -- www.hexagonproject.com -- that allows visitors to "discover the roar of the new creature from Lamborghini."

What does this mean? Well, visitors can push the ignition button from the screen to hear the revs of the supercar's new engine. Lamborghini said nothing about it, but rumors suggest it will be a considerably improved version of the current V-10 engine with its output nearing the 600-horsepower range.

Our only question is why the microsite is called "Hexagon Project" when most people expect the new supercar to be called Cabrera? Could it because we are maybe not listening to the Gallardo's->ke375 successor, but just another special based on the Aventador -- a model that features lots of hexagonal lines? We can't tell for sure, but considering the Cabrera is the only model that Lamborghini is currently testing, to our knowledge, we tend to believe that this is the first teaser for the Gallardo successor.

Lamborghini Cabrera

The Cabrera was caught testing many times and each time it revealed that the new model will feature a new design language, with more aggressive lines and elements inspired by the Aventador supercar.

Rumors suggest that the Cabrera will be powered by the same V-10 engine found in the Gallardo, but a with a special supercharger to crank the final output up to 600 horsepower. The model will also be lighter than the current Gallardo -- about 66 pounds, to be exact -- which will lead to improved performance figures.
