Some interesting four-door sports cars and exotic cars over the years. Ford Mustangs, Porsche 911s, Chevy Camaros, Ferraris, Lamborghinis, Cadillac Eldorados and much more

Four-door sports cars based on two-door coupes (even two-seaters) have always been intriguing. Whether produced by automakers themselves or customized via cut-and-stretch methods by limousine builders, this classification of car represents a slightly rebellious nature. For if two-door Ferraris and Mustangs are the establishment, then a four-door sedan version becomes distinctly anti-establishment.

In chronological order, a slideshow of some sedans that cast aside their mainstream boy-racer images for more mature ones…

: While the 1961-65 Lagonda Rapide was a personal favorite of Aston Martin’s then chairman Sir David Brown, the Rapide saw limited sales of only 55 units over three years before being dropped.

: One side of this early mockup of the 1964 Ford Mustang is a styling exercise to see what a four-door version would look like. The side of the car facing away from the camera is traditional Mustang coupe. This sedan concept later served as basis for the Falcon model of that time.

: It featured an inline 4.0-liter 6-cylinder, dual-overhead-cam engine which produced 236 horsepower. Four wheel disc brakes and all-independent front and rear suspensions were equipped on the Rapide as well. It was a car ahead of its time, and a nicely integrated design based on Aston’s famous coupe featured in early James Bond movies.

: BMW’s 1800ti (1964-71) was a sister version of what Americans know as the 2002ti model sold in the United States from 1968-1976. Unlike the 2002 model that Americans got, European 1800s were also sold as 4-doors.

: This 4-door 1970 Plymouth Barracuda was custom built recently by two craftsman as a result of an old reported sighting of a 4-door model at created at Chrysler’s headquarters in 1969. See our related article here https://bit.ly/3coPwTZ

: During the styling process for the first 1970 coupe-only Monte Carlo model, Chevrolet stylists created this 4-door styling exercise.

: When the following generation of the Monte Carlo was created, this was the official sedan rendering. Typically, clay mockups were done as a coupe on one side, and a 4-door on the other.

: Built in extremely limited numbers during 1974, Aston Martin’s next foray into four-door GT cars was a stretched version of its popular 1970s “V8” coupe model. , this car featured an advanced aluminum block V8 engine of 5.3 liters which produced 350 horsepower.

: Production of the V8 sedan was cut short during the winter of 1974-75 due to financial difficulties the company was having.

: Engineering on these cars was advanced. 1974 Aston Marton V8s featured 4-wheel disc brakes, all-independent suspension, and an aluminum block V8 engine of 5.3 liters which produced 350 horsepower.

: The Monica company was a vision of French railway company CEO Jean Tastevin. Development began on this car in 1967, and just before actual production began the Triumph engine originally planned for use in the car was ditched in favor of an American Chrysler V8 (280 hp) and automatic transmission.

: 1973 – 1975 Monicas featured a suspension of all-independent control arms, and disc brakes at all four corners. As often happens with visionary upstart car brands, the vehicles themselves become a victim of compromise due to financial necessity and fail to appeal fully to their intended target audience. Sales suffer until the company goes into receivership, as did the Monica brand. (Photo credit: Pontfire)

: Designed to celebrate the 50th anniversary Ferrari’s styling house Pinin Farina, Ferrari’s only factory-built 4-door sedan made its world premiere at the 1980 Turin Motor Show in Italy. Initially, it was a non-running concept. (Photo credit: Wikicars)

: The styling of the low-slung sedan was the work of the same stylists that designed Ferrari’s Dino, Daytona, P5, and more. (Photo credit: Wikicars)

: After its debut at the Turin show, the Ferrari Pinin continued its motorshow appearances until 1981 when it was put in storage. It was later sold to a close personal friend of Enzo Ferrari’s, then again in 2008 to its current owner.

: Although the concept was well received by the public, Ferrari never put the Pinin into production. Nevertheless, certain styling cues such as the high belt-line can be found on later models designed by Pininfarina such as the Peugeot 405. (Photo credit: Auto Galeria)

: While the Pinin was originally a non-running concept car, the current owner had it fitted with a 4.9-liter 12-cylinder engine from a 512BB and a specially adapted five-speed gearbox from the Ferrari 400GT. Horsepower was rated at 360. Other changes included the strengthening of the chassis, the addition of a fuel tank plus new suspension and brakes. (Photo credit: Auto Galeria)

: In 1984, a stretched-wheelbase 928 was given to company founder Ferry Porsche as a birthday present by his company. Three years later in 1987, the lengthened 928 that had been presented to the company’s founder on his 75th birthday turned up as a “Feasibility Study”, now with a second set of of rear-hinged doors.

: The Porsche 928 “Study H50” 4-door concept car disappeared without a ripple initially. Two decades later, with the launch of the larger four-door Porsche Panamera, it acquired greater significance.

: Sales of Porsche’s 928 front-engine V8 powered coupe (1978-95) were so strong in the mid-’80s it inspired the company to begin work on a front-engine V8 powered four door, known inside the company as the “989”. This early factory protoype was created after all design and engineering work was locked in.

: Big financial losses Porsche suffered after the recession of 1990 began caused the company to cancel planned production of the 989 in late 1991.

: Although styling of the 989 mirrored the rear-engine Porsche 911, the new model was to be fitted with a front-mounted V8 engine.

: Many Porsche fans considered this a thoroughly thought out styling excercise based on Porsche’s classic 911 two-seater, and its cancellation met with much disappointment.

: Three of these 4-door sedans were based on the new-for-1993 Ferrari 456 front-engine four seater coupe. Built by Pininfarina (the design house which does regular work for Ferrari on production models), they both were commissioned especially for Nafsas Al Khaddaja of South Belgium.

: Not to be outdone, Prince Jefri of Brunei ordered seven of these wagon versions of the 456 GT coupe to be built. After Pininfarina designed and built them, the prince only purchased six. (Photo credit: B. Hughes)

: One of the seven Ferrari 456GT Venice station wagons made.

: This 4-door prototype (photographed testing during 2002) shows that Mini considered a 4-door model as far back as their first generation Cooper. As talk circulates of such a model actually reaching production over a dozen years later, we sincerely hope they keep the rear door and C-pillars at the far corners – without ungainly-looking extra side windows and D-pillars.

: When Mercedes-Benz introduced their new-for-2007 S-class sedan, they rolled out this “Ocean Drive” concept four-door convertible.

: As an April Fool’s joke, Road & Track magazine ran this series of photos showing a 4-door Mustang in development.

: These 4-door Mustang pictures are so well done, it’s hard to believe they are not real. Or maybe they are.

: Currently the Fiat 500 is produced only as a two-door hatchback. Although many differing spy photos of an upcoming four-door model keep surfacing, we like this artist’s rendering of what a 500 “sedan” should look like the best.
