How About an Eight-Liter Lamborghini V12?

It's very similar to the first 3.5 Lamborghini V12 Bizzarrini created for the 350GT, but it's so huge, they wouldn't put it in a car.

Lamborghini is so fond of naturally-aspirated engines that despite outsourcing the Urus' twin-turbo V8 to parent company Audi, its sport cars will continue on without forced induction, even in their upcoming hybrid era.

Since 1963, Lamborghini has had just four different V12 designs. The most famous of those is their first road car engine, which was designed by the genius Giotto Bizzarrini, with the goal of being significantly more powerful than Ferrari's V12s. Much to Ferruccio Lamborghini's satisfaction, their 3.5-liter V12 was more advanced as well, being a quad-cam engine as opposed to Ferrari's, which continued to use single overhead camshafts.

Through the decades, this V12 grew from 3.5 to 3,9, then 4.8-liters, followed by the 5.2, 5.7, 6.0 and 6.5 versions. Finally, it went from 6496 cc to 6498 cc for the 2009 Murciélago LP 670–4 SuperVeloce, before Lamborghini replaced it with its second-generation V12, built for the Aventador.

Lamborghini's rarest V12 was commissioned under the Chrysler Corporation's ownership, when Bob Lutz decided to use the brand for their entry into Formula 1. Lamborghini's new 3.5-liter racing V12 was designed by ex-Ferrari engineer Mauro Forghieri. The LE3512 debuted in 1989, only to be last used by Ayrton Senna and Mika Häkkinen for McLaren's test runs in 1993.

Last but not least, Lamborghini's largest V12s came to be when the company's owners decided to enter the marine business on the side. Motori Marini Lamborghini produced two large engines based on the Bizzarrini V12. The carbureted L900 was a luxury boat motor with roughly 770 horsepower, while the fuel-injected L802 was an eight-liter racing motor producing up to 900 horsepower. Unfortunately, at 990 pounds, it wasn't suitable for Lamborghini's road cars. Not even the LM002.
