The engine, Lamborghini says, is the perfect size for a 12 cylinder. If it was any larger the pistons would become too heavy, the company says, so it is built with optimum response in mind. The engine also uses four throttle bodies which help provide that distinctively deep Lamborghini roar.
Another key aspect to the new engine is its lightness. The entire V12 ensemble weighs just 235kg by using exotic light-weight materials, such as aluminium-silicon alloy for the crankcase and the sand-cast heads. The crankshaft is forged and nitride-hardened and weighs just 24.6kg as well.
Overall dimensions of the pistons mean this baby will rev and rev fast. The bore measures 95mm while the stroke is just 76.4mm. This oversquare design results in less piston travel while still providing a sizeable explosion thanks to the wide bore size. Lamborghini says the engine will have a redline of 8250rpm.
Another new element to the engine is the all-new seven-speed gearbox. It uses ISR technology, or Independent Shifting Rods. Lamborghini says this robotised shifting means gear changes can be done in up to 50 percent less time than a conventional dual-clutch gearbox, and 40 percent faster than the Lamborghini Gallardo e-Gear transmission. This is also made with strength and minimum weight in mind and uses carbon fibre synchronising rings.
Lamborghini recently released a video of the new engine being assembled and tested. Check it out below.
