Some concept cars are the stuff of dreams. In many cases, these vehicles are nothing but design fantasies, with their respective manufacturers never intending to give them the green light for production. But when you give the world’s best car designers free reign to imaging what the future looks like, you end up with automobiles who are insanely gorgeous. Take a look at the 10 cars we wish made it from concept to production:

2006 Ferrari P4/5 Pininfarina


The P4/5 is a one-off sports car made by Ferrari, but redesigned by Pininfarina for film director James Glickenhaus. The car was first an Enzo Ferrario but then owner Glickenhaus preferred a slightly more vintage styling.  Glickenhaus spent $4 million on the redesign and it was officially presented to the public on August 2006 at the Pebble Beach Concours d’Elegance. The P4/5 can accelerate from 0-60 in 3 seconds flat, and has a top speed of 233 mph.


2003 Cadillac Sixteen


The 1,000 horsepower Cadillac Sixteen, featuring a monster 13.6 lire, 32 valve V16 engine, was designed to reference the Cadillac V-16 of the 1930’s. This monster weighed in at 5,000 lbs. and just narrowly fell short of production approval.


2006 Saab Aero X


Unveiled at the Salon International de l’Auto, the twin-turbo V6 running on pure ethanol had Saab fans begging for its production. Saab responded by saying that it wasn’t a priority for them at the time, and the Aero X never saw the light of day.


2008 BMW Gina


GINA, which stands for “Geometry and functions In ’N’ Adaptations,” was a concept designed by BMW’s head of design, Chris Bangle. The GINA never made it to production, instead, the model sits at the BMW Museum in Munich.


1958 Ford X-2000


This amazing creation is the Ford X2000, a styling fantasy from 1958, is what the Ford design department imagined what we would possibly be driving by the year 2000.


2008 BMW M1 Hommage Concept


The recently released BMW i8 is rumored to be what the BMW M1 Homage became.  Back in 2008, this futuristic looking M1 was announced by the company to commemorate the 30th anniversary of the M1. The concept vehicle uses a mid-engne layout and was designed by Giorgio Giugiaro.


2002 Mercedes F400


Unveiled at the 35th Tokyo Motor Show, The F400 Carving is a research vehicle boasting a new system that varies the camber angle on the outer wheel between 0 and 20 degrees, depending on the road situation.


2005 Ford Shelby GR-1


First introduced to the public at the 2005 North American International Auto Show, the GR-1 was created with inspiration from the famed Shelby brand. The project was led by Manfred Rumpel and devalued by Ford’s Advanced Product Creation group, but was never given the green light for production.


2010 Red Bull X2010


The people who made Gran Truism 5 asked Red Bull in 2010 what they would do if they were tasked with designing a race car. Their answer was bonkers. The X2010 was imagined to have a 1,483 horsepower twin-turbo V6, suction aero, and would dust an F1 car.


2008 Citroen GT Concept


Debuting as a concept car on October 2 at the 2008 Paris Motor Show, the collaboration between Citroen and Polyphony Digital were expected to be built – but only six of them, at a price of $2,100,000. However in 2010, rumors that production on the GT was suspended began to surface.


2007 Mazda Furai


The Furai was a concept car that debuted at the 2008 North American International Auto Show in Detroit. Meaning “sound of the wind,” it was the fifth and last of the Mazda Nagare line of concept cars. The Furai has appeared in several video games such as Gran Turismo, and was destroyed by fire during a road test by Top Gear in 2008.
