The most unique and revolutionary concept cars from Italy that sadly never made the streets.

Concept cars aren't meant to be realistic, they're meant to show off what a brand can do, prove they don't have tunnel vision, and are a healthy way to keep their creative legs stretched out. Take a look at Audi's e-tron lineup, for example—they're big, bodacious, extraordinarily expensive, come equipped with never-seen technology, and look like nothing else on the road...but they still capture the Audi brand's characteristics. Then, on the other hand, you have the BMW XM Concept.

While some production-version of cars come nowhere close to their initial concept design, others manage to stay true to their idea, like the Lotus Evija for example. For this list, we'll be diving into some of the most daring, out-of-the-box designed concept cars built by big Italian names like Ferrari and Lamborghini. And we can't help but wonder what their current model lineup—or, well, the entire automotive market—would have looked like today if some of these innovative yet somewhat questionable vehicles made it into production.

Modern-day Ferrari models all share the same goal - sleek, fast, and expensive, but the 512 S Modulo concept car... well that's a bit different. It almost looks as if a Lotus Espirit and a Delorean DMC-12 had an intergalactic child; it had an extremely low ride height of just 36.8-inches, a broad stance, a glass lid that slides open to act as a passage for the driver to get in and out of, and a monstrous V12 engine.

This '70s engine has a displacement of 5.0 liters and pushed out a whopping 550 hp. This meant that the Ferrari flying saucer was theoretically capable of accelerating to 220 mph and reaching 60 mph from a standstill in 3 seconds dead.

Out of all the cars on our list, this is the one we want to be produced the most. Lamborghini has strayed away from its roots the past few years, and it's not all their fault - the market demands powerful SUVs today. But unlike the Urus, the Estoque wasn't a lifted Audi with a V8 motor, no, it would have been propelled by the same naturally-aspirated 5.2-liter V10 found in the Lamborghini Gallardo.

We truly believe that the Estoque would have thrived in today's auto culture; everyone isn't phased by fast super SUVs anymore, and the sports sedan market is ruled by the BMW M5 CS and Mercedes' new AMG GT 63 S E, we'd love to see a Lamborghini-built family sedan in there too.

To quote Italdesign: "It’s not a car, and it’s not a motorbike. The perfect synthesis between them." The Machimoto was Italdesign's attempt at solving the rise in fuel prices back in the '80 without sacrificing seats, and it was built on a VW Golf platform, it even had the 1.8-liter four-banger from the GTI too.

So, to be able to accommodate as many people at once as possible, the Machimoto had a nifty little trick up its sleeve, it could morph from a 6-seater to a 9-seater without a lot of fuss, and because it lacked a roof, headroom was never an issue, but safety might have been.

If you thought the new limited-edition revival of the iconic Countach was Lamborghini's first attempt at making something old new again, you'd be heavily mistaken. In 2006, Lamborghini went and sketched up a new, reimagined Miura without replacing its ancestor's noteworthy style elements like its striking paint, flat, flush face, and rear louvers.

And of course, as Lamborghini does, it was powered by a naturally-aspirated 6.5-liter V12 derived from the Murcielago, and it was capable of pushing out between 600 and 700 hp.

The name Pininfarina shouldn't be unfamiliar to an auto enthusiast like yourself, after all, they specialize in designing all sorts of gorgeous sports cars, especially Ferrari-built ones. Pininfarina has yet to come out with their self-built vehicle, and this is the closest they have come yet, but it's still built in conjunction with the Chinese tech firm called Hybrid Kinetic.

Pininfarina really aced its design; it looks modern, yet still has a classic grand tourer sense to it, its gull wing doors open at just a slight angle, and it comes equipped with four seats in the cabin, so it's practical too. And did we mention it was powered by a 38-kWh battery that causes the four electric motors to wind up more than 1,000 hp?

When we first saw this vehicle, we were in pure disbelief...a Lamborghini V12-powered minivan with gullwing doors that are only found on-high end supercars—we thought we were having a fever dream of an old Pimp My Ride episode. Yet, here we are. We can't imagine the Genesis was meant to be anything more than just a ludicrous show car, but it gets even weirder.

Since this minivan had 455 hp at its disposal, we assumed it would have a standard 6-speed stickshift, or perhaps some one-of-a-kind auto box, but Bertone decided to make use of a 3-speed automatic transmission from none other than... Chrysler? We don't know why either.

Now this entry isn't purely one car, it's actually a whole series of concept cars from Alfa Romeo called the BAT, which was short for Berlina Aerodinamica Tecnica. Throughout the '50s Alfa released the BAT 5, 7, and 9, and every single one was designed by Bertone. They all shared the same design style: an aerodynamic-obsessed body that would eliminate drag as much as possible. And for that reason, the most powerful BAT had only 100 hp but managed to run up to 120 mph thanks to its perfectly sculpted body.

But let's leave numbers alone for a moment and appreciate every single BAT's styling, absolutely breathtaking. And if we're honest, we wouldn't have been surprised to see Batman himself drive one of these, after all, it's called the BAT!

That's right; before Tesla made use of the Model X name with their electric SUV, Pininfarina did all the way back in the '50s, and they both resemble each other as much as a squirrel and a potato chip do.

Pininfarina had the same idea as all other manufacturers during the "Race To Space" era and added some large fins at the rear of its Model X, but what truly made it a sight to behold was its bulbous shape and three-wheel configuration. Perhaps if this car went into production we would have seen a whole genre dedicated to cars that all looked like they were meant to be in an episode of The Jetsons.

And the award for having the weirdest, most ironic name on the list goes to no other than the Maserati Boomerang. Boomerangs are supposed to be curvaceous, and smooth, but Maserati clearly thought otherwise and gave that name to one of the sharpest wedged cars we've ever seen.

It was designed by the iconic Giorgetto Giugiaro, and not only did he pay extra attention to detail in its captivating exterior design, but its entire was equally quirky. Just have a look at that gargantuan steering wheel that holds the different gauges; impractical, but quirky nonetheless.

If you think Fiat is all about producing fun little city cars with their vocal point being achieving good fuel economy, we'd recommend clicking off this article now and continuing living your life in denial. See, back in the '50s, Fiat gave birth to one of the most challenging engineering feats ever, a turbine-propelled sports car.

Surprisingly, its engine only produced 300 hp, but it had a redline of 22,000 RPM, and because its body had an extremely low drag coefficient of 0.14, it could achieve a top speed of 160 mph. The Turbina's idea was scrapped for a very prominent flaw though, it drank fuel like there was no tomorrow, and it was prone to overheat - never would have seen that coming.
