Lamborghini LP700-4 Aventador


Lamborghini has always been known for building hairy-chest-pounding, unapologetic supercars. The kind of cars that make enthusiasts tingle and environmentalists draw on posterboard with big black markers. It was a bit of a shock when Lamborghini recently announced an initiative to increase the efficiency of its Raging Bulls, and fans of Sant' Agata's creations cringed at the thought of smaller, less-powerful cars. Well, they can put their fears to rest, because the new Lamborghini LP700-4 Aventador is as monstrous as any Lambo in history -- and it's more efficient to boot.
The Aventador follows the traditions of the Countach, first produced in 1974. The body is sculpted around the passenger compartment, with the longitudinally mounted 6.5-liter 690-horsepower naturally aspirated V-12 situated in the middle. The look is modern and aerodynamic, but still purely Lamborghini. Driver and passenger enter through scissor doors and the optional clear engine cover allows owners to show off the heart of the beast. The roofline is sculpted to allow for maximum headroom for passengers while tying in the character lines on the hood and minimizing the aerodynamic frontal area. Mechanically operated side intakes are carried over from the Murcielago, allowing air flow to be adjusted based on the engine's current needs.

The clean sheet, aluminum block V-12 features direct injection, variable valve timing, four individual throttle bodies, dry sump lubrication, and an 11.8:1 compression ratio. The big engine has a screaming high 8250 RPM redline accomplished using lightweight internal components and a high bore-to-stroke ratio of 95mm and 76.4mm respectively. Maximum piston speeds have been reduced from almost 24 m/s at 8000 RPM, the Murcielago's redline, compared to 21 m/s at 8250 RPM at the Aventador's redline, resulting in fewer frictional losses. It also uses a new dry sump lubrication system that requires less power, provides better oil scavenging under high cornering loads, and decreases the size of the oil pan. The new system also allows the 518-pound engine to sit 2.36 inches lower in the car, reducing the center of gravity height.
