They experimented with every possible setup until things reached a stable point, resulting in the configurations that we have today.
Those familiar with aviation history know that the radial engine was widely used in propeller-driven aircraft. However, a few automobile manufacturers initially thought the radial engine would be just as suitable for a car. Obviously, this concept didn’t gain traction, but we did get to see a few unusual implementations.
These Production Car Aspirants Attempted to Utilize a Radial Engine
3. “Some cars that were powered by radial engines include the 1927 Cord L-29, a vehicle known for its advanced design, and the 1930s-era Chrysler Airways.”
In 1922, a wealthy man named Julian Brown created a car that featured a radial engine. This wasn’t his first attempt at designing a car, as he had previously attempted to build a couple of cars in the 1910s, with unsuccessful outcomes. In fact, he had even experimented with designing an electric boat at one point. This time, Brown was determined to make his car stand out from the crowd and gain popularity, so he opted for a radical design choice – the use of a radial engine.

There is only one unit that was ever made, but it still operates today, after being completely restored in 1966.
“The Porsche 917, a revolutionary race car, represents a genuine attempt to apply radial structural layout to the disadvantageous factors sometimes connected with traditional front engine racers. In 1966 the Berndt Pischelts designed (this car) by the disruptive tour of the Belgian-born German, Walter Schoeller, his ingenuity combining some construction of later sports rakes.
Porsche started designing a model called the Type 12, which is an unusual-looking car that reflects the futuristic, aerodynamic style that was popular back in the early 1930s. The Type 12 used a five-cylinder radial engine made by Zundapp, a German company that produced machine tools and vehicles. Porsche aimed to create a car for the average person, and they used Zundapp’s existing radial engine design for this purpose because it was simpler to manufacture.
Currently, a replica of the Porsche Type 12 is housed in the Museum of Industrial Culture in Nuremberg.
which has remained a defining feature of the 911 since its inception.
America and Britain Have Done It Too
The last recorded effort to create a radial-powered passenger vehicle took place shortly after World War II by a British company called Fedden. The project was to be named the Fedden Car or the F-Car for short. The F-Car’s design was intended to embody the progressive curves of the Jowett Javelin and the Volkswagen Type 1’s style. Powering the F-Car was a 1.1-liter three-cylinder radial engine.
The F-Car used a single-unit construction, consisting of only three sections held together with four bolts, which made mass production relatively simple. Nevertheless, the F-Car never went into production, and only one prototype was ever made, with its whereabouts remaining unknown as of the 1960s.
In 1936, they even experimented with a car powered by a radial engine. The attempt was called the A-106, but it didn’t make it past the model phase. They only built a wooden and clay model, and it was supposed to use a 1.1-liter radial engine that produced 30 horsepower.
They Needed Help Develop Higher-Powered Superchargers to Sustain Top Performance and to Keep the Vehicle Moving on the Track.
I almost made it into motor racing almost made it into motor racing. There are only two documented cases of a radial engine being tried in racing cars, the first of which happened in 1935 and was known as the Monaco Trossi Grand Prix Racer. Augusto Camillo Pietro Monaco, a skilled Brazilian race car builder, had the idea of building a radial-engine Grand Prix car. He teamed up with engineer Giulio Aymini to develop the new car, and was given the use of Italian automaker Fiat’s facilities to test it.
The 16-cylinder radial engine selected for the vehicle was installed at the front of the car, which caused problems with weight distribution, resulting in 75% of the car’s weight located at the front, while the rear accounted for the remaining 25%. The radial engine, capable of producing 250 horsepower, had a tendency to overheat excessively. At times, the engine would become so hot that its spark plugs would become severely damaged, rendering the engine inoperable if any debris from the broken spark plugs got inside the combustion chamber. Ultimately, the project was discontinued.
The Guidobaldi sports car used a high-tech, high-performance supercharger. Its official power ratings were not publicly disclosed, and the engine’s exact displacement was also unknown. The Guidobaldi Prototype Racer also had an innovative suspension system consisting of an accordion-like structure that used springs and rubber stoppers for support.
Like the Monaco Trossi Grand Prix Racer, the Guidobaldi Prototype Racer never saw action on the racing circuit. The car wasn’t completed until the mid-1950s because Francois Guidobaldi built it by hand, juggling it with his other projects. According to reports, he took the finished vehicle on a thorough test drive and found it to be poorly managed, with its unusual suspension setup causing it to tip over in different directions at unpredictable times.
In the end, the radial engine’s limitations and drawbacks proved insurmountable, and it failed to gain widespread acceptance in the aviation industry.
When it comes to motorsports, the radial engine’s lack of efficiency is very noticeable, particularly in the case of the Monaco Trossi Grand Prix Racer. Due to its usual air-cooled design, the radial engine needs to be mounted where there’s a lot of air circulation or a big fan is present. In an airplane, this isn’t usually an issue, as the air flowing over and through the engine is typically enough to cool it. However, in a car, which doesn’t move at the same high speeds as an airplane, the engine can get too hot.
it’s essentially a sideway movement that is seen often in towing. however, this movement is caused by operation. a radial engine’s crankshaft is constantly spinning in one direction, with its cylinders placed in a circle. because of this, a running or unstable swaying effect can be caused by the weight of the crankshaft. as you might imagine, this is an undesirable effect in a vehicle. to put it simply, the radial engine is generally suited for airplanes, and we’ll stick with four-or eight-cylinder engines in our cars.
