We've been bringing you spy shots and details on the Jota, Lamborghini's replacement for the Murcielago, for years now. This weekend, some specs leaked from a purported secret presentation of the first working prototype in Singapore, and they include the alphanumeric code LP700-4.

That, of course, signifies output of 700 horsepower and all-wheel drive. According to the source at FerrariChat forums, the power comes from a 6.5-liter engine (presumably a V-12) that redlines at 8,250 rpm. Peak torque is stated at 500 pound-feet, and comes at 5,500 rpm. All of that adds up to 0-62 mph in 2.9 seconds and a top speed of 217 mph.

The real surprise, however, is that the car features a carbon fiber monocoque chassis, which shaves about 500 pounds off the current Murcielago's curb weight, and makes it 70 percent stiffer.

According to the source, the car will make its world debut at the Geneva Motor Show next March. For more on the Murcielago replacement/Jota, check out our previous coverage.
