From the invention of the first steam-powered automobile to the advanced electric cars of today, the history of the auto industry is remarkably diverse. Over time, car designs and features have undergone significant changes. Throughout this progressive auto evolution, the role of prototyping has been undeniably crucial.
Automotive prototyping serves as an integral part of the car design validation process that leads to manufacturing. From a mere concept to a production-ready vehicle, auto prototypes provide invaluable assistance at every step of the way.
Here we will discuss the different types of automotive prototypes, detailing their purpose and significance in the car production process.
Before we delve into the details, let’s take a quick look at the history of auto prototyping.
Brief History of Auto Prototyping
The first car prototype is often attributed to Karl Benz, who is credited with inventing the first practical automobile. In 1886, Benz unveiled a three-wheeled vehicle powered by a gasoline engine. This prototype vehicle marked a significant milestone in automotive history.
It was the first automobile to be powered by an internal combustion engine and designed specifically for personal transportation. This development paved the way for the evolution of automobiles and set the stage for the automotive revolution that followed.
Different Types of Auto Prototypes in Car Production
Different types of car prototypes are created for different phases of the automotive manufacturing process. Let’s learn more about them.
Design Validation Prototypes
Design validation prototypes are of different kinds. They include concept cars, which are often showcased at motor shows to gauge customer reaction and feedback on new technology and design. The exhibition of future vehicles at Dubai Expo 2020 is a fine real-life example in this regard.
Similarly, production-intent prototypes are more realistic than concept cars. They are made of the same materials that would be used in the final production vehicles. This makes them a more accurate representation of the final product, allowing more result-oriented prototyping and testing. On a side note, here are some of the best concept cars and their specs for this decade.
Pre-Development Prototypes
After a design has been validated and stakeholders and production teams have given their approval, the early pre-development stage requires a more refined prototype to test usability and address any design challenges.
Automotive engineers sometimes refer to this as the “mule stage.” In this stage, engineers take existing cars (donor cars) and strip them down to their bare frames. After this, they place the prototype products in the donor cars to see how they fit and interact with the other parts. This allows engineers to identify any potential problems and consider design alternatives.
The mule stage is an important step in the development process, as it helps ensure that the final product is safe, reliable and user-friendly.
Production Validation Prototypes
After the mule stage, engineering prototypes are developed and used for production validation at the manufacturing or assembly plant. These car prototypes are developed using various techniques including 3D printing, CNC machining, metal stamping, metal forming and fabrication. At this stage, the most reliable method for finalising and creating the desired automotive product is determined.
Furthermore, the process of working with engineering prototype cars enables engineers to identify potential production problems and ascertain the most cost-effective manufacturing processes. Thanks to advanced technology, the production validation process is also aided by virtual automotive prototypes. These car prototypes also come in handy when working on different kinds of future car technologies.
This prototyping technique is used to evaluate and validate the performance, functionality and manufacturability of the design before physical prototypes are produced.
Safety Testing Prototype Cars
When it comes to the safety testing of automobiles, prototypes play a crucial role. They undergo rigorous testing during the pre-production phase, where real-world usage scenarios are simulated and testing automotive prototypes are subjected to extreme conditions.
Through these safety tests, potential issues or safety risks that could affect the car’s performance and safety are identified and addressed. Many of the key safety features in modern cars are also tested during the process, such as forward collision warning, anti-lock braking system (ABS), adaptive cruise control, etc. This prototype testing phase helps assess the reliability of the car in production.
Customer Testing Prototypes
The customer testing prototype vehicle is very similar to the final product. Customers are given a chance to experience or test-drive these prototype cars. Their feedback is crucial for automotive product development in many ways. It helps engineers sell their concepts to stakeholders, identify potential problems and select the appropriate manufacturing materials.
Customer testing can occur at any of the final stages of the development process. The feedback obtained from these studies or surveys is used to evaluate the product’s desirability, usability, and appeal to potential buyers. However, it is important to note that customer testing for auto prototypes is always conducted in a controlled environment to ensure safety.
Prototyping for Autonomous Vehicles
The primary motive of carmakers today is to make self-driving cars safer than human drivers. However, autonomous technology in cars is still in its primitive stages. Many of the autonomous cars we see today are either concept cars or prototypes that have been tested. The maturing process of their software quality and machine learning is in the works.
Since these vehicles will have a lot of sensors and actuators to drive on their own, safety testing becomes all the more important. That said, there are still different types of challenges that self-driving cars have to overcome before their widespread adoption.
This was all there is to know about the role of different auto prototypes in car production. Additionally, other advancements have been made in car manufacturing processes, such as the introduction and application of nanotechnology in the auto industry.
The more advance the vehicles get, the more complex their production becomes. All the models you see in these listings of used cars for sale in the UAE may have gone through the various stages of auto prototyping during their first production run before becoming road-ready.
