01 / THE STORY
History & context
The Fiat X1/10 design mock-up by Bertone represents a fascinating and enigmatic chapter in the history of automotive design. Created in the late 1970s, this prototype was conceived as either a successor to the celebrated Fiat X1/9 or as an entirely new addition to the Fiat Group’s lineup. Its story remains shrouded in mystery, with two competing narratives adding intrigue to its legacy. The first account suggests that the project was initially developed for Lancia, intended to slot beneath the Beta Montecarlo in the brand’s lineup. Just before its presentation to management, however, the project was reportedly redirected to Fiat. Notably, the mock-up lacks any badges, possibly a deliberate choice to leave its branding open for Fiat Group executives to decide. The second version of the story ties the X1/10 more directly to the Fiat X1/9. While the X1/9 was a commercial success, it faced criticism for its cramped cabin. In response, Bertone’s X1/10 aimed to address these concerns by offering a more spacious design. It featured two front seats and a child seat positioned behind the passenger seat, while the spare wheel was relocated behind the driver’s seat. This configuration suggested a practical evolution of the X1/9, though its exact positioning in the Fiat lineup remains unclear. Was it intended as a replacement for the X1/9 or as a slightly more premium companion model? While Fiat may have seen the idea as redundant and potentially cannibalistic, Bertone viewed it as a credible niche offering to bolster its business and maintain strong ties with Fiat Group. The X1/10 prototype itself is a testament to Bertone’s forward-thinking approach. Constructed using an advanced combination of glass resin and chalk, it showcases the innovative materials and techniques employed in Bertone’s design experiments. Painted in a bold metallic green, the mock-up exudes a sense of modernity and dynamism. This striking color choice underscores the vision of the Italian design house, blending aesthetic appeal with forward-looking ideas. Stylistically, the X1/10 reflects Marcello Gandini’s evolving design language, which he had introduced with the Ferrari 308 GT Rainbow three years earlier. The prototype also incorporates design elements reminiscent of the Volvo Tundra, further highlighting Gandini’s influence. However, Gandini did not see the X1/10 through to completion, leaving Bertone in mid-1979. It is believed that Marc Deschamps took over and finalized the project, though Fiat ultimately declined to move it into production. Despite never reaching the market, the Fiat X1/10 remains an invaluable artifact in automotive history. Preserved in Bertone’s archives, it serves as a tangible reminder of a transformative period in car design, characterized by bold experimentation and innovation. Its sleek lines, futuristic proportions, and thoughtful interior layout hint at what could have been a significant step forward for compact sports cars. As one of Bertone’s least-documented projects, the X1/10 continues to captivate enthusiasts and historians alike. It stands as a vivid symbol of Bertone’s creative legacy and its impact on the automotive world, a testament to the ambition and ingenuity that defined the Italian design house during its golden era.

- Independent specialist history supports the X1/10 as a late-1970s/1980 Bertone proposal and surviving full-scale static model.

Engine & performance
- Specification notes
- The surviving Bertone X1/10 is documented as a full-scale static design mock-up, not a running vehicle. Production X1/9 engine and chassis data are therefore not inherited.
