There are a few internet speculators that are anticipating the exotic Italian super car builder Lamborghini will unveil their topless version of the jet fighter inspired Reventon at the upcoming auto show this September. It would make sense for the Reventon Roadster to say hello to the entire world from Frankfurt, after all it was at the same show two years ago that the very stealth like Reventon made its official debut.

Details about the upcoming open air Lamborghini are not very clear, especially when it comes to the engine that will power the new Reventon->ke2866. Initial rumors said that vehicle will use the same engine as the Lamborghini LP670-4SV, but the automaker might have problems putting all that power to the ground safely in a Roadster body. So the only thing that is left is the engine from the Lamborghini LP650-4 Roadster.

Either way it won't matter which engine they choose, because the most attractive feature of the Reventon is its exterior, and because the it will be built as an extremely limited edition model, demand for the open air Reventon will always be in the stratosphere no matter how much power it makes, but will it be ready in time for Frankfurt?
