The Aventador priced at around $450k has a 6.5L 700 HP V12 in the rear with all wheel drive and a single clutch ISR transmission while the $691k Ferrari F12 has a 6.3L 730HP V12 mounted up front with rear wheel drive and a dual clutch transmission.
As you can see the video it’s a pretty close race from a roll, with Ferrari F12 having a slight edge simply due to it’s dual clutch transmission which allows it to shift faster than the Aventador and gain a tiny bit each time the Aventador has to switch gears. Of course from a roll it would be a different story as the Aventador’s all wheel drive system would catapult it ahead putting the Ferrari so far behind it would most likely never be able to catch up.
