New Lamborghini V12 and ISR transmission * updated with assembly Video *
This V12 is claimed to be a new design, 6.5 liters, sporting 700 horsepower and 509 pound-feet of torque.
The interesting thing is the transmission. ISR (independent shifting rod) is said to shift 50% faster than a comparable dual clutch transmission! It employs dual shifting rods that make it weigh considerably less as well... interesting.

The new engine is a naturally aspirated 6.5 liter V12, known internally as the L539, with a total output of 515 kW (700 PS) at 8,250 rpm and 690 Nm of torque available at an engine speed of 5,500 rpm.
The new V12 was developed by Lamborghini at its Sant'Agata Bolognese facility. It comes with a classic cylinder bank of 60 degrees and is compact - measuring 665 millimeters tall, 848 mm wide and 784 mm in length. It has a bore diameter of 95 mm and a cylinder stroke of 76.5 mm. The nitride-hardened crankshaft weighs just 24.6 kg while the engine weighs a total of 234 kg.
The 6.5 liter V12 also comes with two mufflers in a single casing - one low-volume and the other high for that pitch-perfect Lambo sound.
Also newly developed to accompany this engine is the ISR (Independent Shifting Rods) transmission. A 7-speed, single clutch gearbox with exceptionally quick shift times due to the independent shifting rods - Lamborghini claims almost 50 percent less than a standard dual-clutch gearbox. The independent shift rods work similar in concept to a dual-clutch - as one rod is disengaging the current gear, the second rod is already engaging the next one.
Weight reduction is a theme here too, as the new gearbox weighs in at just 70 kg.
The transmission comes with three driver settings - Strada, Sport and Corsa mode - with Corsa mode made for high-performance driving that also includes a launch control function.

Lamborghini is an awesome company, helping fund that carbon fiber research center/school and developing new technologies for more efficient acceleration. 4 throttle bodies on that thing, and 700 horsepower NA while passion modern emission standards, a transmission that shifts faster, weighs less and is likely more efficient than any other out there.
Now if only I could find some $$$$$............
