How to summarize a decade using a few numbers. In 2001, the horses were 580, now 700. In 2001, the acceleration of 0-100 km / h was covered in 3.8 seconds, now 2.9. In 2001 … better stop here, stop the comparisons, not to be disrespectful to the Murcielago. We think today, the new sedan with a V12 engine. So welcome Aventador LP700-4. Welcome by that name a bit ’so, a new example of bullfighting (a bull Aventador was awarded the “Trofeo de la Peña La Madroñera”following the fighting in the arena of Zaragoza), although less exciting and more complicated than many Miura , Countach, Diablo and Murcielago precisely. Welcome with all your technical and technological solutions from frame to engine, suspension from the exchange rate system to the new media bill.

The LP700-4 Aventador measuring 4.78 meters in length, 2.26 in width (including outside mirrors), and only 1.13 in height, for a mass of 1575 kg distributed with 43:57 ratio of the sum and result of considerable prestige among the various components: the monocoque weighs 147.5 pounds, just complete the 229.5 frame, the 6.5-liter V12 does not exceed the 235 pounds and change ISR merely 79 kg. The Aventador LP700-4 uses carbon fiber and composite materials in large quantities, which helped to contain the emission of pollutants (-20%, 398 g / km CO2) than the Murcielago despite a considerable increase in performance. In fact, the twelve-cylinder delivers 700 hp at 8,250 rpm and 690 Nm at 5,500 rpm, values that allow power to reach a weight of 2.25 kg / hp. The idea 0-100 km / h is then burned in 2.9 seconds and top speed exceeding 350 km / h.

The baggage of early and refinement can not be separated from the transmission ISR Robotic (gearshift times less than 50 m / s), the push-rod suspension and chassis of carbon fiber with an index of torsional strength equal to 35,000 Nm per degree . Not forgetting made of carbon-ceramic brake discs (400 mm and 6-piston front, 380 mm and 4-piston at the rear) alloy wheels hidden behind by 19, and 20-inch tires that wear 255/35 and 335/30. The technicians then del Toro have developed a system of four-wheel drive with Haldex viscous coupling, apparently less sophisticated than a Torsen yet more versatile and immediate reactions: it is possible to address up to 60% of torque to the front wheels when The standard ratio is 30:70. The Aventador also uses a locking rear differential to 40%, rear spoiler and tilt adjustable from 4 to 11 degrees and an electronic device that provides the launch control function, and three driving modes (Normal, Sport and Racing). It ‘even possible to modify the response of the engine mounts.
