the Secret MINI Superleggera Prototype and How It Almost Went Into Production

When the MINI Superleggera Vision debuted at Villa d’Este in 2014, it looked almost too perfect to be real — a minimalist, hand-formed sculpture that captured MINI’s spirit while stripping away every trace of clutter. But it wasn’t just a showpiece. This was a fully functional prototype, hand-built over nearly a year with engineering as beautiful as its design. Here’s the story of how MINI not only design but actually built the most beautiful MINI ever.

A Coachbuilt MINI for the Electric Age

The Superleggera Vision was born from a rare collaboration between MINI Design in Munich, led by Anders Warming, and Touring Superleggera, the legendary Milanese coachbuilder whose name literally means “super light” in Italian.

Touring handled the construction the old-school way: hand-shaped aluminum panels wrapped around a tubular space frame, built using the same techniques that once created Aston Martins and Maseratis. Every curve, joint, and line was formed by hand. The result was a structure that weighed next to nothing and radiated the kind of craftsmanship modern manufacturing can’t replicate.

While MINI supplied the design and vision, Touring’s artisans turned those sketches into metal. This wasn’t a modified production shell. It was a completely bespoke chassis and body, engineered from the ground up.

The Secret production Based Prototype

Before the aluminum masterpiece was born, MINI quietly built a styling prototype using an R59 MINI Roadster as a test mule. That car served as an early proving ground for proportions, stance, and design details like the signature fin and minimalist interior.

Engineers and designers used it to experiment with surfacing, lighting, and even seating position before handing things off to Touring Superleggera. Only after the concept was fully resolved in clay and on the Roadster mule did the team move to the final hand-built aluminum version. That step ensured the Superleggera’s proportions felt grounded in MINI reality, even as it pushed far beyond it.

MINI’s Plan to Build It

After its debut, enthusiasm inside MINI and BMW was enormous. Designers, engineers, and executives all saw potential in turning the Superleggera Vision into a low-volume production model. For months, MINI explored how to make it happen.

One path involved re-engineering it on the UKL platform, which underpinned the Cooper and Countryman at the time. This version would have been front-wheel drive and offered in combustion form. MINI even went as far as developing feasibility studies, cost models, and early clay revisions for a slightly taller, production-friendly version.

But the numbers never worked. Building an aluminum-bodied two-seater by hand was far too expensive, and adapting the design for steel production would have compromised the proportions that made it special. It could have been watered down and built on the line as MINI did with the R59 Roadster but there was concern it would have lost what made it so special. MINI leadership ultimately concluded that while it could be built, it couldn’t be sold profitably.

Still, the internal desire was strong enough that the Superleggera lived on in MINI’s design studio for years as a reference point. Its influence was felt in the brand’s next-generation design language, especially in the clean surfacing and lighting now visible on the J01 electric Cooper.

A Bespoke Build With R59 Components

Despite the Roadster connection, the finished Superleggera Vision did not share its platform. MINI engineers borrowed suspension and steering components from the R56-generation Cooper S parts bin, but the chassis itself was custom-designed to accommodate an electric drivetrain and rear-wheel-drive layout, something no MINI had ever done before.

The result was a car that looked familiar in size and proportion but was fundamentally different underneath.

A BMW i3 Heart

Power came from an early BMW i3 drivetrain, a rear-mounted electric motor and single-speed gearbox producing about 170 horsepower. According to sources, the lightweight frame and compact dimensions made it lively, balanced, and quiet, almost surreal for a MINI in 2014.

BMW’s i-division engineers worked side by side with Touring to integrate the system into the hand-built frame. Every component, from battery placement to wiring harnesses, was adapted by hand. It was an engineering puzzle that shouldn’t have worked, but it did.

Tested, Tuned, and Alive

The Superleggera Vision wasn’t static art. It was tested around Munich and later driven on BMW’s private test track. Its proportions, shorter, wider, and lower than any production MINI, were a direct result of that custom frame and the compact electric drivetrain. The drive experience reportedly matched its looks: light, direct, and pure.

What It Meant Inside MINI

Within MINI Design, the Superleggera became a symbol of what could happen when design leads engineering. Though the production version never materialized, its influence is still visible today, from the surfacing and lighting of the J01 electric Cooper to the minimalist interiors shaping the brand’s next generation. It may not be the exact same aesthetic, but there are similar concepts behind them both that drive towards simplicity.

It also reminded us that MINI could move beyond retro without losing its soul. Underneath that stunning aluminum body sat a true electric MINI roadster, one that pointed toward a future the brand is only now catching up to.
