Engine swaps have always been one of the more exciting aspects of automotive customization, especially when someone decides to squeeze a powerful engine into a vehicle that was never designed to accommodate it. However, one enthusiast recently took things a step further by using a 3D scanner and artificial intelligence to help fit a turbocharged Volkswagen engine into a tiny Renault Twingo.
The builder took to Reddit’s r/projectcar community on October 24 to share photographs of the ambitious project involving a first-generation Renault Twingo. Rather than sticking with the little hatchback’s original engine, the owner is installing a Volkswagen 1.8-liter turbocharged 20-valve engine, transforming the compact city car into something considerably more exciting.
Of course, fitting an entirely different engine into such a small vehicle presents several challenges, particularly when it comes to mounting everything securely inside the engine bay. Fortunately, the builder has been using modern technology to eliminate much of the guesswork traditionally associated with custom engine swaps.
According to the Reddit post, the owner used a 3D scanner to capture the engine bay and surrounding components before designing custom engine mounts using computer-aided design software. Even more surprisingly, the builder credited ChatGPT with helping align the scans and develop the mounts, making the unusual project an interesting combination of traditional mechanical work and modern digital tools.
Renault Twingo Builder Uses 3D Scanning and AI To Simplify Engine Swap

According to the original post, the builder scanned the Volkswagen engine and relevant parts of the Twingo before using CAD software to determine how everything would fit together. This allowed the owner to visualize the engine’s position on a computer rather than repeatedly lifting, repositioning, and measuring the components inside the vehicle.
The enthusiast explained that the process was particularly helpful when designing custom engine mounts, which would otherwise require considerable trial and error. So far, the physical components appear to be fitting as expected, with the owner describing the ability to visualize the project digitally as a major improvement over traditional fabrication methods.
Interestingly, the builder is also documenting the project through a YouTube channel called Kris Duprey’s Garage, where a dedicated engine-swap video is expected to be published. The owner hopes to have the Volkswagen engine running within approximately two weeks of the original Reddit post, although the swap is still underway and its final performance remains to be seen.
Comments and Reactions to Renault Twingo’s Ai-Assisted Engine Swap
Several Reddit users were excited about the idea of fitting a turbocharged Volkswagen engine into such a small hatchback, with some suggesting that the finished vehicle could become an unexpectedly quick sleeper. One commenter pointed out that the Twingo’s relatively low weight could make even a modest increase in horsepower feel substantial, particularly if the builder eventually achieves the approximately 250-horsepower target discussed in the community.
Others were more interested in the technology behind the project, asking about the affordability of 3D scanners and whether they could simplify their own engine swaps. One enthusiast with roughly 20 years of engine-swapping experience explained that digital scanning could make the process considerably easier compared with the traditional methods they had used.
The builder responded by identifying the scanner as a Creality Raptor X, acknowledging that it was a relatively expensive investment but expressing enthusiasm about how much it had helped. With the project still progressing and additional videos planned, the unusual Renault Twingo has already attracted interest from enthusiasts eager to see whether its Volkswagen-powered transformation lives up to expectations.
