Lamborghini's filed a claim with the U.S. trademark office on the name "Aventador." Some believe it's the new name for the Italian automaker's Murcielago-replacing supercar. Below, what the name means and specifications we expect for this new raging bull.

According to a self-identified participant in a Lamborghini preview, the upcoming LP700-4 is the Murcielago replacement we've been calling Jota. It'll offer a 700-hp V12, a carbon-fiber body, sub-3.0-second 0-to-62 mph time, and hit 217 mph.

Hey, look at the secret Lamborghini spy shots, just leaked on the net! It's the 2012 Jota! Or maybe... someone just tried to milk the Lambo Cnossus design study from earlier this year. [CarConceptDesign]

According to AutoGuide, contrary to popular belief the Lamborghini Jota will not debut in Paris, neither will the rumored "83X" Gallardo replacement, instead Lambo will only show a "technology concept." Well, that explains all the teaser images. So confusing. [AutoGuide]

Two fully-camouflaged variants of the Lamborghini Jota were seen testing at the Nurburgring, one with a spoiler, one without. Could it be Lamborghini's mysterious 83X project is really a Jota Superleggera?

Whether it's the Murcielago-replacing Lamborghini Jota, or the Lambo-that-isn't-Jota-as-it-only-has-ten-cylinders, this third teaser image belongs to one of two Paris Motor Show Lamborghini unveils and gives us our first glimpse of the devilish black-and-red-themed carbon fibergasmic interior.

According to a leaked Lamborghini meeting agenda, two models are headed for a Paris reveal: the "LB715-5″ (the V12-powered Jota) and the mysterious "83X." This 83X could be a Gallardo-replacement (i.e. the V10-implying teaser image), Estoque, SUV, Baby Lambo... [0-60Mag]

The Lamborghini Jota's over-the-top design will redefine what "supercar" means, as shown in this teaser. But Lamborghini's got another mission: no more fatties. They say top speed's irrelevant and will focus on handling and weight reduction through more carbon fiber.

This is the first glimpse of what's rumored to be the Murciélago-replacing, 700-hp Lamborghini Jota, set for a debut at the Paris Motor Show. Angular.
