DETROIT -- Though saving the unveiling of its upcoming supercar until the Geneva Motor Show in March, Lamborghini divulged several major technical details about its Murcielago replacement.
The vehicle will retain its V-12, all-wheel-drive layout, but the body and chassis will be entire constructed from carbon fiber, said Maurizio Reggiani, Lamborghini's r&d chief.
Teaming with Boeing Corp. and the University of Washington for research help, Lamborghini created a carbon fiber tub and body that boasts stiffness calculated as 35,000 Newton-meters per degree of deflection. By comparison of stiffness, the Koenigsegg CCR is 28,100 Nm, the Ferrari F50 is 34,600 Nm, and the existing Murcielago is 20,000 Nm.
The V-12 engine will remain at 6.5 liters, but with a different bore and stroke. It will generate 700hp and 509 foot-pounds of torque. It also will produce 20 percent fewer CO2 emissions, about 390 grams per kilometer, Reggiani said.
The gearbox, still sourced from Graziano Trasmissioni Group, will be the first seven-speed automatic mated to a V-12 engine. When in “Corsa” mode, shifts can be accomplished in 50 milliseconds. By contrast, a typical Formula 1 racecar shifts in 40 ms.
Rather than borrow Audi's dual-clutch gearbox technology, Lamborghini will use a single-clutch with dual synchronizers, which Reggiani says weighs 44 pounds less and occupies less space.
Slowing the car will be carbon ceramic disc brakes, 400mm in the front, 380mm in the back. The suspension will feature horizontal dampers connecting to double wishbones, very similar to how Formula 1 cars are equipped.
Although Lamborghini officials declined to give the name of the car -- referring to it by code name A34 -- the company has applied for the U.S. trademark name “Aventador.”
