The Alfa Romeo Carabo was unveiled at the 1968 Paris Motor Show.
Carabo was designed by Marcello Gandini at Bertone design.
The orange and green paint scheme was influenced by the color patterns of the Carabidae beetles. The Carabo name is also a reference to these beetles.
The Carabo concept is considered as the direct predecessor of the Lamborghini Countach, De Tomaso Panthera and many similarly styled cars of the day. Its wedge design and scissor doors were included in many supercars that were designed and developed by Marcello Gandini and others in the 1970 and 1980s.
Though it wasn’t intended to become a production model, the concept car was fully functional, and it was built on the chassis of an Alfa Romeo 33 Stradale. It also retained the rear mid-engine layout of the Alfa Romeo 33.
It was powered by a 2.0-liter V8 engine. It was then mated to a six-speed Colotti manual transmission. This setup delivered 230 horsepower at 8800rp. The maximum torque was 148 lb-ft of torque at 7000rpm.
The whole car weighed under 1000kgs due to the excessive use of composite materials.
Alfa Romeo Caimano
The Alfa Romeo Caimano was designed by Giorgetto Giugiaro of Italdesign and was unveiled at the Turin Motor show in 1971.
It was based on a more conventional front-wheel drive, front-engine layout. This setup was very similar to the system used in the Alfa Romeo Alfasud, with the only difference being the shortened length of the car by almost 8 inches.
It features many unconventional design features such as the large glass canopy windshield and roof, which also act as doors to provide access to the car. It also featured small windows on the doors for ventilation, or to exchange documents with the relevant authorities.
The B and C pillars form a trapezoidal roll bar in the rear of the car. This setup also doubles as an adjustable spoiler that can be controlled from inside the cabin.
The car also features pop-up headlights, to provide a more aerodynamic body shape.
The dashboard is cylindrical and was an unusual design for the time being.
Since Caimano was based on the drivetrain of Alfa Romeo Alfasud, it was powered with the same 1.3-liter water-cooled flat four-cylinder engine, which was dubbed as the Boxer H4. Despite the small displacement, this engine delivered an impressive 86 horsepower when connected to a five-speed manual transmission.
The car is now exhibited at the Museo Storico Alfa Romeo.
Alfa Romeo Navajo
Just like the Alfa Romeo Carabo concept, the Navajo was also based on the Alfa Romeo Tipo 33 Stradale. When it was unveiled back in 1976, it looked nothing like the world has ever seen. It looked like a federation space shuttle straight from the Star Trek TOS.
Alfa Romeo Tip 33 Stradale was designed by Franco Scaglione. The car was a beauty and received much appreciation from the press and public alike, but its skyscraping 9.75 million Lira price tag was too much for many Italians at the time. In comparison, the Lamborghini Miura costs only 7.7 million Lira.
Only six cars were made out of the originally planned 18 cars.
The leftover chassis were sent to various design studios such as the Bertone, Carrozeria, Italdesign, and Pininfarina.
The Alfa Romeo Navajo was designed and developed by Nuccio Bertone of the Bertone design.
It was named after the legendary red Indian tribe.
It isn’t good-looking as the Alfa Romeo Tipo 33 Stradale, one of the most beautiful cars ever made. However, there’s some sci-fi mystique attached to the Alfa Romeo Navajo.
The Alfa Romeo Navajo concept received mixed reviews back in the day. Some people argued that it is the most creative car of its time, some considered it as hideous.
It was based on the chassis of the Alfa Romeo Tipo 3 Stradale. The chassis was then mated to a tubular space frame structure.
Its bodywork was completely made out of fiberglass.
The styling was featuring a wedge profile with smooth yet straight-edged boy lines. These styling cues were adopted to apply the latest aerodynamic tricks they learned.
The active spoilers were used in front and rear to improve downforce. Two rear trapezoid wings were fitted to draw hot air from the 2.0-liter V8 engine. This engine was capable of revving up to 8800rpm redline to deliver a maximum output of 220 horsepower.
Due to the excessive use of composite materials, the whole car weighed only 870 kg, therefore offering impressive power to mass ratio.
The popup headlights emerged from the front wing of the car instead of being located on the hood. The whole car was shorter than a Mini Cooper classic and was only 41 inches tall. These small dimensions made this car even more aerodynamically efficient.
Alfa Romeo Cuneo (P33 Roadster)
The Alfa Romeo Cuneo was designed by Paolo Martin of Pininfarina design studio. It featured an aggressive wedge-style body to improve aerodynamic efficiency.
The Italian word Cuneo meant Wedge and it was a reference to the styling cues of the car.
It was based on the chassis of the Alfa Romeo Tip 33 Stradale and featured the tubular space frame chassis and a mid-mounted 2.0-liter V8 engine.
This concept was unveiled at the 1968 Turin Auto show.
This car featured a low wraparound windshield and an aggressively swept-back aero foil.
The car was designed to be minimalist in nature. The aesthetics and the overall design of the car were simple but beautiful in their own right. The subtly curved fins span the entire length of the car, the tilted cover over the velocity stacks was supported by a strut of a small rollover bar. The massive front wheel arches were subtly bulging over the front fascia of the car, without drawing too much attention.
The car featured no doors and the whole car was of a single tub design which was similar to the Formula 1 cars.
The car was scrapped after some time to create a different prototype.
Alfa Romeo Iguana
The Alfa Romeo Iguana was designed by Giorgetto Giugiaro at Italdesign. It was unveiled at the Turin Motor show in 1969.
It was the first Alfa Romeo model to be designed by Giorgetto Giugiaro. This car was also based on the chassis of an Alfa Romeo Tipo 33 Stradale. Iguana also retained the rear mid-engine rear-wheel-drive layout of the Tippo 33 Stradale.
The entire body was finished in a metallic gray finish and the roofline and the cabin pillars were finished in a brushed metal texture.
Many of these styling cues were later used to develop the DMC DeLorean. The brakes were Girling disc brakes and Campagnolo alloys were used.
The suspension system featured upper and lower A-arms at the front and rear.
The Alfa Romeo Iguana was equipped with the same 2-liter aluminum V8 engine. This engine was then mated to a Colotti six-speed manual to deliver 230 horsepower at 8000rpm.
The engine was capable of delivering 260 horsepower easily, but it was deliberately detuned to deliver 230 horsepower only. This was done to improve engine life and reliability. This engine also featured a SPICA fuel injection system for increased efficiency.
This car was capable of reaching a top speed of 161.6mph.
Later, the 2.0-liter V8 engine was replaced with a 2.5-liter V8 engine derived from the Alfa Romeo Montreal. This engine now delivered only 200 horsepower.
