In the early 1960s, the British Motor Corporation had a bold idea. Could the iconic Mini be transformed into a stylish, affordable sports car to compete with the Fiat 850 Spider and Triumph Spitfire? The answer, though tantalizingly close, never reached production. Today, the story of the ADO34, 35, and 36 offers a fascinating look into automotive ambition, corporate politics, and the paths not taken.
The ADO34 project represented both vision and frustration. Engineers at MG in Abingdon and Longbridge aimed to turn the Mini into a nimble, low-cost sports car. Conflicting priorities, cost concerns, and the strong opinions of Alec Issigonis, the Mini’s creator, meant the project quietly faded away. For enthusiasts in Dubai and across the UAE, understanding this story highlights how innovation can be both inspiring and fleeting.
The Vision of ADO34
Between 1960 and 1964, BMC explored expanding the Mini’s appeal beyond its compact saloon form. The ADO34 project was intended as a direct replacement for the MG Midget and Austin-Healey Sprite, with variants including a coupé (ADO35) and an Austin-Healey-branded roadster (ADO36).
The plan was simple: use the Mini’s proven front-wheel-drive mechanics and agile handling, wrap them in sleeker bodies, and deliver an affordable sports car. BMC even looked abroad for expertise. Longbridge sent Mini subframes and tuned A-Series engines to Pininfarina in Turin, where Italian designers reimagined the Mini as a stylish roadster. Meanwhile, MG engineers experimented with stretched Mini chassis to create a design that hinted at the MGB’s proportions.
Conflicting Designs: Abingdon vs Longbridge
The Abingdon prototypes reflected a British approach. Engineers extended the Mini Countryman wheelbase and added a compact roadster body. While visually tidy and promising, practical issues soon appeared. The chassis lacked stiffness, causing severe scuttle shake on uneven roads. This made the car feel unstable and almost undriveable.
Longbridge’s collaboration with Pininfarina offered a different solution. The Italians created a separate chassis, addressing rigidity, and designed a sleek body with showroom appeal. Painted gold with red trim, it looked every bit a modern sports car. Yet this fix introduced new problems. Moving away from the Mini’s architecture made the car expensive and complex, undermining the goal of a low-cost vehicle.
Alec Issigonis reportedly disliked the Pininfarina prototype, seeing it as a departure from the Mini’s simple, efficient design. Engineers in both Abingdon and Longbridge found themselves at an impasse. Neither prototype offered a complete solution, and no design gained full approval.
ADO35 and ADO36: Coupé and Austin-Healey Variants
The ADO34 project included plans for a coupé (ADO35) and an Austin-Healey-branded roadster (ADO36). Neither progressed beyond mock-ups. The coupé showed promise but retained Abingdon’s structural weaknesses, while the Austin-Healey version explored styling ideas that never moved forward.
Had these cars reached production, they could have offered a Mini-based sports car capable of competing in Europe and beyond. Instead, the MG Midget and Austin-Healey Sprite continued well into the 1970s with minimal updates, leaving the Mini’s sporty potential largely untapped.
Why the Project Failed
Several factors led to the program’s quiet demise:
- Engineering Limitations: Abingdon prototypes were too fragile, while Pininfarina’s designs were expensive and complex.
- Corporate Politics: Competing visions from Abingdon and Longbridge slowed progress, with no unified direction.
- Cost Concerns: A separate chassis increased production costs, undermining affordability.
- Market Priorities: The MGB already captured attention and sales, reducing urgency for a new Mini-based roadster.
- Design Philosophy Conflicts: Issigonis valued simplicity, efficiency, and Mini authenticity, making radical departures less acceptable.
By 1964, the program was quietly abandoned. The Mini continued its successful run, and the Midget and Sprite remained in production.

The surviving ADO34 prototypes at the British Motor Museum show the potential and pitfalls of automotive innovation. They reveal how cost, politics, and personal vision shape the fate of even the most promising projects.
For modern car enthusiasts in Dubai and across the UAE, the ADO34 story is a reminder of the balance required between design, engineering, and market demand. Even with ambition and creativity, practical realities often dictate whether a concept reaches the showroom.
Although the ADO34, 35, and 36 never entered production, their influence can be seen in later compact sports cars that blended style with agile handling. Mini-based roadsters remain a sought-after niche today, showing that the idea was ahead of its time.
