Lamborghini has divulged more details on the upcoming Murcielago replacement known as the LP 700-4.

New in those details is the body and chassis construction which will be made entirely from carbon fiber, according to Lamborghini's research and development head Maruizio Reggiani.

To create the LP 700-4's carbon fiber tub and body, Lamborghini partnered with U.S. aerospace company Boeing Corp. and the University of Washington for help in developing the material. The frame and body feature a stiffness of 35,000 Nm per degree of deflection. That's greater than in comparable supercars such as the Ferrari F50 (34,600 Nm) and the Koenigsegg CCR (28,100 Nm), and a huge improvement over the outgoing Murcielago (20,000 Nm).

The new 6.5 liter V12, upgraded from the previous unit with a different bore and stroke, doles out a remarkable 700 PS (690 bhp / 515 kW) and 690 Nm (509 lb-ft) of torque. The gearbox, still supplied by Graziano Trasmissioni Group, is a 7-speed automatic (single clutch with dual sychronizers) with shift times of just 50 milliseconds when in "Corsa" (race) mode. For comparison, a Formula 1 racecar shifts in 40 ms. This transmission weighs 20 kg (44 lbs) less and take up less space than in the previous unit.

All that adds up to a curb weight of just 1575 kg (3,472 pounds) and with those construction details we get a better idea of how Lamborghini arrived at a 0 to 100 km/h sprint time of only 2.9 seconds for the model, likely to be called the Aventador. Top speed is 350 km/h (217 mph).

The car also features a Haldex all-wheel-drive system and carbon ceramic disc brakes - 400mm at the front and 380mm at the rear. The F1-style suspension features horizontal dampers connected to double wishbones.

Lamborghini has trademarked the Aventador name in the United States but we still await Lamborghini's confirmation on the naming of the LP 700-4.

The model is scheduled to make its debut at the Geneva auto show in March.
