For a company with only two principal model lines, Lamborghini sure has been busy lately. The limited run of Reventon seven-figure supercars are still rolling off the line, the Gallardo LP560-4 is reaching the market, the crowds at the Paris Motor Show were wowed by the four-door Estoque concept, there's an anticipated Superveloce (SV) version of the Murcielago on its way, and all the while, the team at Sant'Agata has been working on an all-new supercar. Sources differ on whether the new model, tentatively known as the Jota (reviving a classic Lamborghini nameplate) will emerge as another limited-edition ultra-car to rival the Ferrari Enzo or whether it will serve as the replacement for the aging Murcielago. The latter has been on the market for about seven years now in various iterations, the original breeding the Roadster, the LP640 revision, a handful of Versace editions and the aforementioned Reventon. But Lambo has known for a while now that its supercar, as eminently desirable as it remains, is due for replacement.

The spy shots, snapped (where else) at the Nürburgring, show a test mule running with Murcielago bodywork, only with a few key modifications that betray its secret identity like Clark Kent caught without his glasses. For starters, the wheels are bearing what appears to be some sort of telemetry hubs. The vehicle also appears even wider than the linebacker Murcielago, and the vents behind the side windows have a different shape. Eyewitness accounts suggest the new Raging Bull will wear lightweight carbon fiber bodywork, except for the doors and roof, which seems like an odd choice. The Reventon-inspired bodywork is expected to be laid over an aluminum spaceframe to replace the current Murcielago's outdated and overweight steel tub. We expect the vehicle to retain its all-wheel-drive system – by now a hallmark of modern Lambos – with power coming from the latest version of the company's perennial V12, but with the potential addition of direct injection for improved power delivery. Whether the car in question will emerge as yet another limited version of the existing Murcielago or its anticipated replacement will become clearer as we get closer to its anticipated debut in two years as a 2011 model. But our money's on the latter.
